Introduction: University Safety Manual
Michigan Tech’s mission to “prepare students to create the future” involves the use of a wide variety of hazardous materials and processes that require special training and control measures to protect students, employees, and our environment from harm. The following University safety, health, and environmental policy and the management program outlined in this document form the basis for accomplishing our mission in a safe and environmentally responsible manner.
Michigan Tech Safety and Environmental Policy
The Safety Policy of Michigan Technological University is based on the firm conviction that accidents that cause personal injury or damage to property or the environment can be prevented. No phase of University business or operation is of greater importance than the safety.
Michigan Technological University will provide and maintain a safe and healthy environment at all locations and will establish operating practices designed to assure the safety of all.
All students, faculty, and staff are responsible for their individual safety performance and for protection of the environment. Each instructor/supervisor also has the responsibility to create a climate of safety and environmental awareness. Safety and environmental protection must be an integral part of every job. It is the responsibility of all to comply with safety rules and to work in such a manner as to prevent injuries to themselves and others and to prevent damage to the environment.
The prevention of accidents and the protection of the environment are in the best interest of all. Only through constant mutual effort and cooperation can we achieve these goals.
Dr. Glenn D. Mroz, University President

Chapter 2: Emergency Action and Fire Prevention Plan
2.0 Emergency Action and Fire Prevention Plan
This section contains general emergency response procedures to be followed in the absence of department- or facility-specific procedures. The supervisor or person responsible for the area where an emergency occurs is responsible for investigating all emergency incidents and reporting them to Environmental Health and Safety.
2.1 Building Evacuations
There are several types of actual and potential emergency situations that might necessitate a building evacuation including fire, explosion, chemical spill, gas leak, terrorist threats, etc. The evacuation alarm is primarily intended for initiating a general evacuation during fire emergencies. During emergencies other than fire, the possibility that occupants could enter a danger area (e.g., chemical spill in exit path, potential explosion area, exposure to gunman, etc.) while exiting the building should be considered before initiating the evacuation alarm. In those instances where a general evacuation is not safe, the evacuation will have to be conducted room by room in buildings that do not have a public address system.
2.1.1 Physically Disabled Occupants
It is the responsibility of faculty to notify students in each class of the need to identify themselves (in private, if desired) if they will need assistance during a building evacuation and to establish an evacuation plan for those identified. Such evacuation plans may include the buddy system and the use of safe refuge areas—places relatively resistant to smoke and heat within a building (for example a sprinkler protected room or hallway, or a stairway landing) where an occupant could wait until help arrives to assist in an evacuation. If a safe refuge area is to be used, it is essential to assign, at the time of the emergency, a specific individual with the task of notifying emergency responders of the location of the waiting occupant.
Employees are responsible for identifying themselves to their supervisor if they will need assistance during a building evacuation, and the supervisor is responsible for establishing a workable evacuation plan for those employees.
2.2 Building Fires
- Initiate a building evacuation using the nearest alarm pull station.
- Dial 911 to notify Public Safety and request fire department assistance.
- If the fire is small and you have been trained in the use of portable fire extinguishers, you may attempt to extinguish the fire.
- Use the nearest safe exit route to exit the building. Close all doors on the way out to prevent the spread of smoke and fire.
- After exiting, immediately proceed to a safe location at least 100 feet from the building.
- Do not re-enter the building until the all-clear is given by Public Safety or the fire department.
2.3 Medical Emergencies
- Evaluate the immediate area for potential safety hazards (fire, toxic or explosive gas vapors, etc.) or situations that may require moving the injured to a safer location. Otherwise move the injured no more than necessary.
- Dial 911 to notify Public Safety and request first aid assistance or an ambulance.
- Provide emergency first aid as needed if you have been trained to do so.
- If the injury involves exposure to a hazardous chemical, provide the Material Safety Data Sheet to the medical emergency responders. If the MSDS cannot be located in time, call the emergency room to offer the information as soon as possible.
2.4 Chemical Spills
Each employee responsible for an activity involving the use of a hazardous substance must prepare a written procedure to be followed in the event of a spill and communicate the procedure to any students, contractors, visiting scholars and scientists, and employees involved in the activity. The written procedure and associated training must include information on when to request outside assistance.
The following procedures are for chemical spills that cannot be handled safely by persons working in the area.
2.4.1 Developing Written Spill Response Procedures
Individuals that supervise the use or storage of hazardous chemicals and materials
must develop written procedures for responding to a spill of those chemicals and materials. For more information on developing spill response procedures, see the American
Chemical Society (ACS) “Guide for Chemical Spill Response Planning in Laboratories.” Spill response procedures must prioritize human health and safety and clearly define
the circumstances when a spill can be safely managed by on-site personnel and when
it is necessary to seek outside assistance. Supervisors must ensure that everyone
who uses hazardous chemicals and materials is trained to manage spills and knows how
and when to get outside assistance if necessary.
If a spill or release is immediately dangerous to life or health OR on-site personnel are unable to safely manage the spill, seek outside assistance as described below:
2.4.2 Spill of a Hazardous Chemical or Material Inside a Building
- Evacuate everyone in the immediate area and close all doors as you leave. If there is a potential risk to others in the building pull the nearest fire alarm to evacuate the building.
- From a safe location, call 911.
- Give the dispatcher your location: e.g., Michigan Technological University, in Houghton, along with the location on campus including the building name and room number.
- Describe the situation, any injuries, and if there is a fire or potential for a fire.
- Contact your supervisor. Explain what happened and tell them what is being done in
- It is expected that supervisors will ensure that the department safety officer, department chair, director and/or dean are aware of the incident.
- If you are unable to contact your supervisor, contact your departmental safety officer or unit leader (chair, director, dean).
- From a safe location, meet campus Public Safety and Police Services (PSPS) and other
emergency first responders. Provide them with directions to the location of the spill/release
and information about the spilled or released substance including:
- Name of substance(s), quantity released, and any known hazards;
- A copy of the Safety Data Sheet(s), if available;
- Other hazards that may be in the room / area.
2.4.3 Outdoor Spill of a Hazardous Chemical or Material
- Evacuate anyone in the immediate area.
- From a safe location, Call 911.
- Give the dispatcher your location: e.g., Michigan Technological University, in Houghton, along with a description of location on campus.
- Describe the situation, any injuries, and if there is a fire or potential for a fire.
- If the hazard is primarily to the environment and the spill is too large to be cleaned up by on-site personnel OR has the potential to reach the Portage Lake waterway, including through storm drains, request assistance from Environmental Health and Safety. Do not attempt a cleanup once you have determined that outside assistance is needed, or if the spill has entered the soil, groundwater, or surface water.
- Contact your supervisor. Explain what happened and tell them what is being done in
- It is expected that supervisors will ensure that the department safety officer, department chair, director and/or dean are aware of the incident.
- If you are unable to contact your supervisor, contact your departmental safety officer or unit leader (chair, director, dean).
- Remain a safe distance away from the spill and warn others to stay clear until help arrives.
- When campus Public Safety and Police Services or other emergency responders arrive,
provide directions to the location of the spill and information about the spilled/released
- Name of substance(s), quantity released, and any known hazards;
- A copy of the Safety Data Sheet(s), if available;
- Any other hazards in the area.
2.4.4 Management of the Scene During a Spill
- Public Safety and Police Services (PSPS), local Fire Departments, Michigan Tech staff, and others responding to the spill or release will use established Incident Command/Unified Command structures to manage the active incident.
- PSPS will secure the area to ensure safety and prevent unauthorized entry, based on guidance from the “Emergency Response Guidebook,” and / or consultation with knowledgeable persons at the scene.
- PSPS will contact Michigan Tech Environmental Health and Safety (EHS) for assistance.
- Based upon recommendations from EHS and other knowledgeable persons at the scene Incident
- Prohibit access to the room / building / outdoor area until the spilled / released material is properly cleaned and the area has been determined safe for general occupancy.
- Declare the room, building, or area safe for re-entry.
2.4.5 Demobilization After the Spill is Cleaned Up and the Area is Declared Safe
- EHS will work with PSPS/Incident Commander to ensure any remaining concerns are addressed.
- Upon clearance for re-entry, PSPS will take the lead in reopening the room / building /area.
- Incident and Injury Report(s) must be submitted by the supervisor(s), providing details of the incident and documenting any injuries to employees. A separate report must be submitted for each injured employee.
- An after action meeting will be convened by EHS for debriefing. This meeting shall be scheduled within 1 week of the incident and shall include all involved parties (Examples Include: EHS, PSPS, the affected department(s), Facilities Management, local Fire, local County Emergency Management, etc.).
- Following the debriefing and after action report should be generated outlining steps to be taken to help prevent future incident occurrences, as well as ways to improve the emergency response.

Chapter 3: Safety, Health, and Environmental Policies
3.0 Safety, Health, and Environmental Policies
3.1 Government Regulations
Policy: Michigan Technological University will comply with all federal, state, and local
safety, health, and environmental regulations.
Additional Information: Due to the large number of these regulations, it is not feasible to list or summarize them here. Environmental Health and Safety is responsible for communicating the requirements of these regulations to appropriate University departments and employees on behalf of the University administration and for making them available to students and employees as needed.
3.2 Children in the Workplace
Children: Persons under the age of 18
Policy: To ensure the safety of all children, it is University policy that children under the age of 12 are permitted in the workplace (such as offices, classrooms), with prior approval of the department chair, manager, or director and in accordance with the guidelines below. Children age 12 and under who are not enrolled in a Michigan Tech class or program are not allowed in laboratories at any time.
The following rules apply to ensure the child's safety and to respect others working in the space:
- The child must be under the parent or guardian's supervision at all times and must not be unaccompanied
- The child must not have access to any laboratory or other hazardous areas.
- The child must not be disruptive to others in the work place.
- Appropriate measures must be taken to ensure the privacy of the personal information if the child is in the workplace.
- Must comply with University Policy 1.02 Minors Involved in University-sponsored Programs or Held in University Facilities.
Individuals age 13-18 must, at all times, be under the direct supervision of the designated laboratory supervisor while visiting or participating in MTU sponsored activities in laboratories containing hazardous chemicals or equipment.
3.3 Employees and Graduate Students Leaving the University or Department Transfers
Policy: Prior to leaving the University or transferring to another department, academic employees and graduate students must complete a workspace cleanout form. Department Chairs and/or School Deans are responsible for ensuring that the form is completed correctly and that each employee or graduate student has properly disposed of all waste materials from their office, laboratory, shop and/or other work or storage areas. Waste materials include but are not limited to chemical and hazardous waste, scrap, raw materials, product samples, and laboratory/research samples. Any equipment, unused chemicals, laboratory/samples, etc., that are not disposed of must be transferred to another responsible member of the department as indicated on the cleanout form. A digital copy of the completed and signed workspace cleanout form is submitted according to instruction provided on the form. A hard copy of the completed and signed form will be kept on file with the department.
3.4 Donations of Chemicals and Waste Minimization
Policy: Donations of laboratory chemicals, or substances which would be subject to Michigan
Hazardous Waste regulations at the time of disposal, shall not be accepted without
approval by the Director of Environmental Health and Safety and shall not exceed the
quantity necessary for use in an ongoing or funded project.
Additional Information: Minimization of chemical waste is in the best interest of the faculty and staff as well as the University. Excessive laboratory waste production diverts valuable funds away from more productive activities and increases the regulatory compliance burden on the University. Because there is a direct correlation between the total University chemical inventory and our total waste production, waste minimization must begin with chemical inventory minimization. Chemicals should be acquired in the amounts needed for a specific project and not simply to have on hand. Current purchase and delivery services make this practice unnecessary and waste disposal costs make the practice short sighted. Effective methods to minimize laboratory waste include micro- or reduced-scale experiments, just-in-time delivery for reagents, good housekeeping, proper labeling, prompt disposal, and ordering only what is needed for the project.
3.5 Building Construction and Renovation
Policy: All proposed projects involving changes in use, alterations, construction, or additions
to buildings or spaces owned or operated by Michigan Technological University shall
be approved in writing for adequacy of utilities and life safety by Facilities Management
and Environmental Health and Safety prior to requesting a purchase order, funding,
or construction bid proposal. Facilities Management and Environmental Health and Safety
will also conduct a physical space review before a new or renovated space may be occupied.
Additional Information: Departments or individuals considering a potential building renovation or alteration should contact Facilities Management, which is responsible for the administration of these activities.
Policy: All University employees are prohibited from wearing portable stereo headsets or any other devices that may limit the hearing capabilities of the employee while on the job. This does not include protective devices that are required for hearing safety.
3.7 Student Projects
Policy: A hazard analysis shall be completed for each student project. Students working on projects shall complete a hazard analysis for the proposed project to identify hazards; evaluate the potential risks connected with the hazards and determine appropriate ways to eliminate the hazards and/or control the risks. This shall be done during the early planning stages of the project and continually re-evaluated with the implementation of new procedures, tools, equipment, processes, materials, chemicals, etc. Students shall also commit to following safe working procedures and sharing the responsibility for safety with other members of the project team.
Advisors of student projects shall, oversee the hazard analysis process for evaluating the health, safety and environmental hazards associated with the project and ensure that appropriate methods are used to mitigate risks connected with these hazards. Advisors are encouraged, as needed, to enlist the help and support of departmental or other University systems and personnel with knowledge and expertise related to the project.
This policy applies to projects where work is conducted without the immediate and
direct supervision by University faculty or staff. new or renovated space may be

- Class-A—Limited voltage protection
- Class-B—High voltage protection
- Class-C—No voltage protection
A Class-C helmet or any metallic head device shall not be furnished or used for head protection, except where it has been determined that the use of other types of protective helmets or safety hats or caps is impractical, such as where chemical reaction will cause the deterioration of other types of head protection.
Bump hats or caps or other limited-protection devices shall not be used as a substitute for protective helmets for the hazards described in this section.
A hat, cap, or net shall be used by a person where there is a danger of hair entanglement in moving machinery or equipment, or where there is exposure to means of ignition. It shall be designed to be reasonably comfortable to the wearer, completely enclose all loose hair, and be adjustable to accommodate all head sizes. Material used for a hair enclosure shall be fast dyed, nonirritating to the skin when subjected to perspiration, and capable of withstanding frequent cleaning. It shall not be reissued from one person to another unless it has been thoroughly sanitized.
5.1.5 Hearing Protection
When a noise exposure of 85 dBA (an environment where normal speech levels can not be understood) is exceeded for any eight-hour time period, a hearing conservation program shall be established. If there are concerns that this action level of 85 dBA may be exceeded, Environmental Health and Safety should be contacted to make noise measurements and to assist in selecting appropriate noise abatement measures and establishing a hearing conservation program, if necessary.
5.1.6 Foot Protection
Each affected person shall wear protective footwear when working in areas where their feet are exposed to electrical hazards or where there is a danger of foot injuries due to falling or rolling objects or a danger of objects piercing the sole of the shoe. Safety shoes and boots which are not worn over shoes and which are worn by more than one person shall be maintained, cleaned, and sanitized inside and out before being reissued.
Where a hazard is created from a process, environment, chemical, or mechanical irritant that would cause an injury or impairment to the feet by absorption or physical contact—other than from impact—footwear, such as boots, overshoes, rubbers, wooden-soled shoes, or their equivalent, shall be used.
All protective footwear purchased after July 5, 1994, shall bear a permanent mark to show the manufacturer's name or trademark and certification of compliance with the provisions of American National Standards Institute (ANSI) standard Z41-1991 (now ASTM F2412-05 and F2413-05).

5.1.7 Respiratory Protection
Selection of respiratory protection is solely the responsibility of Environmental Health and Safety. Any person who suspects the presence of a hazardous air contaminant must request assistance and obtain approval from Environmental Health and Safety before selecting, or using, a respirator or dust mask. More information about respiratory protection can be found in the written University Respiratory Protection Program.
5.2 Working Alone
Students, contractors, visiting scholars and scientists, and employees may not work alone if the work involves exposure to hazards that are potentially life threatening, could inhibit self-rescue, could cause injuries requiring immediate assistance, or pose a fire or explosion hazard beyond the person's ability to respond effectively. Appropriate methods to address the need to perform such hazardous operations include the buddy system, intercom communication to a nearby area, periodic supervisor inspections, periodic phone contacts, etc., as long as the method implemented is appropriate to the level of hazard and the required response time in the event of an incident. Each department is responsible for establishing a system and criteria for approving requests to work alone.
5.3 Hot Work
Hot work is any temporary activity involving an open flame or that produces heat, sparks, or hot slag. This includes, but is not limited to, brazing, cutting, grinding, soldering, thawing pipes, torch-applied roofing, and welding. Such activities will require the issuance of a Hot Work Permit before beginning hot work and adherence to the procedures outlined in the University Hot Work Program.
5.4 Exposure to Blood-borne Infectious Diseases
Each department must determine if they have employees whose required job duties result in actual, or reasonably likely, exposures to human blood or other potentially infectious body fluids. If so, a blood-borne infectious diseases program must be established to protect them from exposure. The program will include a written compliance plan, employee training, the use of universal precautions, personal protective equipment, engineering controls, and offering the hepatitis-B vaccination series.
Employees who believe that their required job duties involve exposure to blood or other infectious materials should contact their supervisor to see if they should be part of the department blood-borne infectious diseases program. If the department does not have an existing blood-borne infectious diseases program, the supervisor should contact Environmental Health and Safety for information and assistance in determining whether a program is needed.
Students or employees who are concerned about potential exposure to blood-borne infectious diseases due to Good Samaritan activities may also contact Environmental Health and Safety for information about protective measures that can be taken.
5.5 Asbestos In Buildings
Several older campus buildings were constructed using a variety of products containing asbestos fibers. These products most commonly include structural steel fire insulation, steam pipe fitting insulation, and floor tiles. Although some of the asbestos-containing materials have been removed, it is neither economically feasible nor prudent to attempt to remove it all.
Wherever asbestos-containing insulation is located above a suspended ceiling, only authorized and trained employees may lift or remove the ceiling tiles for any purpose. Maintenance or other procedures that have the potential for releasing asbestos fibers are not allowed except under controlled conditions by trained and authorized employees.
It is the responsibility of each department to inform employees of the existence and location of asbestos-containing products in their work areas and the health reasons for avoiding contact with, or disturbance of, asbestos fibers. Department officials should contact Facilities Management for information on the types and locations of asbestos-containing materials in their building.
5.6 Safety and Health Training
Each department shall be responsible for providing safety orientation training for each new employee within five days of their start date. Additional training must also be provided as required for specific tasks and, depending on the task, may be required before the employee is permitted to begin work.
5.6.1 Training Responsibilities
- Individual department chairs, deans of schools, and directors are responsible for ensuring that safety training is provided for all employees, as appropriate.
- Supervisors and faculty members are responsible for providing training to employees and students under their supervision and are responsible for requesting Environmental Health and Safety assistance when needed.
- Employee supervisors are required to attend all safety training provided for their employees.
- Environmental Health and Safety is responsible for providing the safety portion of the training associated with the use of forklifts, respirators, portable fire extinguishers, shipping and receiving dangerous goods, and asbestos work. Other training may be requested on a case-by-case basis.
5.6.2 Qualifications, Training Content, and Record Keeping
Except where the qualifications of the trainer are specified in a regulation or standard, department chairs may assign training duties to knowledgeable employees as appropriate. Likewise, the content of the training may be determined by the trainer, except where specified in a regulation or standard.
Environmental Health and Safety should be consulted to determine whether the training content is specified under a particular regulation and can assist with content and training materials and aids.
All safety training shall be documented in writing and a record retained for a period of no less than two years for annual training and for the duration of employment for one-time training.
5.6.3 Training Topics
Every employee, including student, temporary, and part-time employees, shall be given safety orientation training before beginning any job assignments. The safety orientation should include general information about emergency response procedures, how to report injuries, how to obtain emergency assistance, and how to get additional safety information.
Additional training may be required by specific safety and health standards before an employee is assigned to perform tasks covered under the standard. Examples include heavy equipment operation, electrical work, exposure to blood-borne pathogens, work with radioisotopes, chemical laboratory work, respirator use, hazardous materials shipping and receiving, and many others.
All departments are responsible for contacting Environmental Health and Safety to assist them in determining what type of safety training is required and appropriate for their employees.
5.7 Incident and Injury Investigations and Reporting
Supervisors, including faculty, laboratory managers, office managers, etc., are responsible for investigating and reporting incidents involving injury or property loss in their area as well as close calls or “near misses.” The supervisor will complete a Supervisor's Incident and Injury Investigation Report and submit a copy to Environmental Health and Safety. The form also serves as a helpful investigation guide.
Incident investigations typically involve a review of the location as well as interviews of all who were involved in or observed the incident. Emphasis should be placed on identifying the underlying causes of the incident rather than placing blame. The investigation is not considered complete until all actions that will prevent recurrences have been identified. Corrective actions taken as a result of the investigation should be documented.
If the injured employee, including student employees, requires medical attention, a copy of the Workers Compensation Return to Work Form should be filled out by the physician after completing the examination and submitted to Environmental Health and Safety. The supervisor may insist that an injured employee be seen by a doctor if in his/her judgment it is prudent to do so. Injuries to students during class activities or on University property should also be reported, however, students may not be forced to accept medical treatment.
All employee fatalities must be reported to Environmental Health and Safety immediately, regardless of cause.
Chapter 6: Storage and Handling of Hazardous Materials
6.0 Storage and Handling of Hazardous Materials
The use and storage of hazardous materials is regulated by the Michigan Right to Know Law, also called the Hazard Communication Standard. The Right to Know Law affects nearly every employee at the University because it applies to the use of all chemicals or products that have a documented safety or health hazard. Such substances include toners and cleaners used in office environments, janitorial supplies, lubricants, welding electrodes and gases, metal stock, etc. The MIOSHA Laboratory Standard supersedes the Right to Know Law in chemical laboratories.
6.1 The University Hazard Communication Plan
The University Hazard Communication Plan requires containers to be properly labeled and Material Safety Data Sheets to be maintained in an organized collection and available at all times to employees in each work area. It also requires each employee to be trained in the interpretation of Material Safety Data Sheets, the protective measures to be taken, the symptoms of exposure, and other information related to the substances they use. Each person who supervises students or employees exposed to substances regulated by the MIOSHA Hazard Communication Standard must be familiar with the University Hazard Communication Plan and comply with its requirements.
6.2 Flammable Liquids Outside of Laboratories
Storage of flammable liquids in buildings shall be limited to that required for the operation of office equipment, maintenance, and classroom demonstrations in addition to the following restrictions:

6.4 Labeling Requirements for Hazardous Chemicals
Hazardous chemicals subject to this labeling policy include any chemical which is
classified as a physical hazard or a health hazard, a simple asphyxiant, combustible
dust, pyrophoric gas, or hazard not otherwise classified. The full definition of these
substances can be found in 29 CFR 1910.1200(c), adopted by reference into MIOSAH Part
92, the Hazard Communication Standard. This policy does not apply to hazardous chemicals
that remain inside of a chemical laboratory where the labeling requirements of the
written laboratory chemical hygiene plan apply.
1. The MIOSHA hazard communication standard requires labels on all original containers received from the manufacturer or vendor to have the following information:
a. Product identifier (chemical or product name)
b. Signal word (“danger” or “warning” – "Danger" is used for the more severe hazards, while "warning" is used for the less severe hazards)
c. Hazard statement(s) (a statement assigned to a hazard class and category that describes the nature of the hazard(s))
e. Precautionary statement(s), and
f. Name, address, and telephone number of the chemical manufacturer, importer, or other responsible party
These labels may not be removed or defaced while the substance is in the workplace. If part or all of the information on the label becomes illegible, a new label with the same information must be created and affixed to the container.
It is recommended that containers be dated on receipt and working containers be dated when filled or topped off. This helps prevent the expiration of older stock and assists in disposal decisions.
2. Secondary container labels (portable containers, spray bottles, sample bottles, flasks, etc., containing the original substance, working solutions, or mixtures) must have the following information:
a. Either the items listed in 1), above, or:
b. The hazardous chemical name(s) [the names must be the same as those used on the original container and the SDS] and a written description or GHS pictograms showing the hazard(s) present. Mixtures and solutions must include the names and concentrations of all components in the container, for example, 10% Clorox Bleach in water or 5 molar hydrochloric acid.
Secondary container labels must be legible and durable so that the information cannot be easily washed off or stained. If part or all of the information on the label becomes illegible, a new label with the same information must be created and affixed to the container.
Example label in accordance with 2) b), above:
10% Clorox Bleach in water
Causes mild skin irritation and serious eye irritation
Chapter 7: Environmental Protection
7.0 Environmental Protection
7.1 Waste Disposal
Numerous types of wastes are generated at the University, and their disposal is regulated under a variety of federal, state, and local laws and regulations. The following is a general description of most waste streams and how they are regulated and disposed of. Environmental Health and Safety should be contacted for specific information regarding proper waste disposal procedures.
7.1.1 Office Waste
Michigan solid waste rules regulate the disposal of solid office waste, which includes such things as paper, cardboard, textiles, etc. These items may be placed in wastebaskets and the large trash receptacles outside each building. Office equipment and machines, furniture, and liquid wastes may not be disposed of in these office waste receptacles.
7.1.2 Sewer Waste
The City of Houghton municipal waste ordinance regulates the disposal of wastewater from kitchens, bathrooms, and work areas. The intent of the ordinance is to avoid the accumulation or release of toxic or flammable vapors within the system and to prevent damage to the treatment plant or contamination of the environment. Solvents, cleaners, and other substances that are not intended for use in the fixtures connected to the sewerage system may not be disposed of in any drain without prior approval from Environmental Health and Safety.
7.1.3 Old Furniture and Equipment
Michigan solid waste rules for scrap metals apply to the disposal of metal furniture and equipment or components. As long as the scrap does not include other regulated substances like mercury, PCBs, or oil, it can be disposed of by contacting the Grounds Department for removal. Also contact the Grounds Department for disposal of wood or plastic furniture and large pieces of wood. Equipment or components containing circuit boards, cathode ray tubes, mercury, PCBs, or other hazardous substances may not be disposed of with other materials in this category.
7.1.4 Lighting, Computers, and Monitors
Michigan's Universal Waste Rules regulate the disposal of computers, video monitors, televisions, and fluorescent lights. Facilities Management coordinates the disposal of all fluorescent light tubes at the University unless they are broken. Broken fluorescent light tubes are disposed of as hazardous waste through Environmental Health and Safety. Contact Central Stores for disposal of all fluorescent light tubes, computers, video monitors, and televisions. Computers without batteries or monitors may also be disposed of as scrap metal by contacting the Facilities Grounds Department.
7.1.5 Laboratory Waste
Laboratories generate a number of waste streams that include medical waste, hazardous waste, liquid industrial waste, broken glassware, empty containers, chemical spill cleanup debris, and supplies. Prior approval must be obtained from Environmental Health and Safety before any laboratory waste, except for office-type wastes, may be disposed in drains or placed in wastebaskets or outdoor receptacles. The rules and regulations affecting the collection, storage, and disposal of laboratory wastes are too extensive and complex to summarize in this document. Prior to generating chemical wastes, contact Environmental Health and Safety for information and assistance in identifying and classifying laboratory waste streams for disposal and to ensure compliance with applicable regulations.
Once appropriate waste collection procedures have been implemented, a waste chemical may be disposed of by submitting a completed collection request form available from Environmental Health and Safety, which will pick up the waste, place it in temporary storage, and then arrange for its disposal.
Waste disposal costs vary widely depending on the quantity and type of waste as well as the type of collection container used. It is highly recommended that Environmental Health and Safety be contacted during the project planning stage to discuss waste minimization and disposal options. The University policy on laboratory waste minimization can be found in Section 3.4.
Broken glass must be collected in a designated broken glass container; labels on empty reagent containers should be defaced prior to disposal in the regular trash.
7.1.6 Non-Laboratory Chemical Waste
Chemical wastes (such as old cleaning products, fuels, solvents, asbestos contaminated materials), and biohazardous wastes (such as blood-contaminated sharps) are regulated in Michigan. A waste determination must be made at the time of generation of each waste type to determine if and how it is regulated. Storage, labeling, handling, and disposal of these wastes are subject to the requirements discussed above. Environmental Health and Safety should be contacted for training and information related to the generation and disposal of these types of wastes.
7.2 Spill Prevention and Control
Highly toxic, flammable, or environmentally hazardous liquids should be stored in unbreakable containers, when possible and glass containers should be placed in secondary containment devices. When these liquids are dispensed, provisions must be made to prevent them from spilling into or entering a sink or floor drain. This can be accomplished by working within a containment device or area, covering the drain opening, etc. All drum quantities of hazardous liquids should be stored in a secondary containment device. An appropriate type and quantity of liquid absorbent material should always be available wherever hazardous liquids are used or stored. Users must be trained in spill cleanup procedures, as well as when and how to request outside assistance.
In the absence of a substance- or area-specific emergency spill response procedure, follow the procedures outlined in Section 2.3.
Chapter 8: Electrical Safety
8.0 Electrical Safety
8.1 Portable Equipment, Tools, and Appliances
All portable devices must be UL-listed for the intended use. In addition, tools that are not double insulated and appliances with metal housings must be grounded. Electrical cords must be free from damage, unauthorized repairs, and deterioration. Portable tools or devices used in wet or damp locations or near a source of water must be protected by a ground fault circuit interrupting (GFCI) outlet or adapter.
8.2 Fixed and Hardwired Equipment
Non-portable equipment wiring and connections must meet the requirements of the National Electrical Code and MIOSHA Part 39. A local disconnect capable of being locked out must be provided.

8.3 Electrical Welding Equipment
All electrical welding equipment must meet the requirements of the Michigan General Industry Safety Standard Part 12 for welding and cutting.
8.4 Extension Cords
The use of extension cords is restricted to portable equipment intended to be moved from place to place. Items that are capable of being moved, for example a desktop computer, but are part of a fixed workstation are not considered portable. Surge protection devices are not considered to be extension cords when used to protect sensitive electronics.
Extension cords may not be used as an alternative to fixed wiring or to extend the existing electrical supply capacity of a work area. Instead, request that Facilities install additional outlets.
Never combine extension cords end to end and always verify that an extension cord is rated for the maximum capacity of the load to be applied and for the environment in which it is to be used. Do not run an extension cord under carpeting or where it will be damaged or cause a tripping hazard.
8.5 Electrical Safety-Related Work Practices
Employees who face a risk of electrical shock that is not reduced to a safe level by the installation design must be trained in the safety-related work practices that pertain to their respective job assignments and the requirements of MIOSHA Safety Standard Part 40. Job titles of employees typically requiring such training include but are not limited to: electrical and electronics engineers, electrical and electronics technicians, electricians, equipment operators, welders, painters, and their supervisors. Training and work practice requirements specific to these employees can be found in the University Electrical Safe Work Practices Plan.
Unauthorized persons shall not tamper with electrical fuse boxes, alter existing wiring, or install electrical wiring. Facilities Management authorizes, in writing, those personnel specifically permitted to work on campus electrical circuits. All electrical wiring installation, service, and maintenance will be performed in accordance with the National Electrical Code and MIOSHA General Industry Standard Part 39.
Chapter 9: Equipment Safety
9.0 Equipment Safety
Departments purchasing new or used equipment are responsible for ensuring that all required and necessary safety guards and systems are in place and properly functioning before using the equipment. The fact that a piece of equipment is new is no assurance that it meets MIOSHA requirements for the protection and safeguard of the operator.
Employees and students are responsible for replacing any guards that have been removed for maintenance or adjustments before operating the equipment and for reporting any missing guards to their supervisor so they can be replaced before the equipment is put back into operation.
Students and employees who operate equipment subject to the lockout provisions of the University Hazardous Energy Control Program must receive training in those procedures prior to operating the equipment.
9.1 Grounds Keeping and Heavy Equipment
Grounds keeping and heavy equipment including lawn tractors, end loaders, dump trucks, and road graders, must be operated and maintained according to the manufacturer's instructions. Operators must be trained according to the manufacturer's operating instructions as well as any applicable equipment-specific MIOSHA standards.

Employees who work in metal or wood shops must be qualified by education and/or apprenticeship in the operation of the equipment and must also be trained according to the applicable requirements of MIOSHA General Industry Safety Standards Parts 26 and 27. Operators should also be familiar with and follow the manufacturer's operating and maintenance instructions.
Adequate space must be provided for aisles, layout, material handling, and machine setup and maintenance.
9.5 Welding and Cutting
Only employees who have been properly trained and authorized by their supervisor may perform welding and cutting operations using electrical or fuel-operated equipment. In addition, authorized employees must also be trained in the safe operation of the equipment, and the University Confined Space Entry and Hot Work programs. Equipment must meet the requirements of MIOSHA General Industry Safety Standards Part 12. In addition, the supervisor shall select and provide personal protective equipment according to the requirements of MIOSHA General Industry Safety Standards Part 33 for welding and cutting operations.
The principle hazards to welders are: fire, burns, electric shock, metal vapor poisoning, bruises, and explosions of compressed and/or flammable gases.
The welder's clothing should be nonflammable, have no pockets, cuffs, or folds, and must completely cover all skin areas. A long leather apron with a high bib is desirable for outer clothing. Gloves with long gauntlets prevent metal from burning the welder's wrists. Shoes should have tops high enough to extend up inside the trouser leg. Ears should be covered only when goggles are worn.
Appropriate eye protection must be worn at all times. All faculty, staff, students, and visitors are required to wear eye protection in areas classified as potentially hazardous to the eye, including protection from welding flash. Detailed requirements are outlined in the MIOSHA Face and Eye Protection Standard (Part 35) available from Environmental Health and Safety.
Be sure the arc welder is insulated and transformers are grounded. Dry leather gloves and nonconductive flooring are standard.
In welding operations, metals with coatings of lead, zinc, cadmium and other toxic metals present fume hazards. Other noxious fumes, depending upon the base metal being welded and the welding rods used, can include the oxides of nitrogen and carbon, copper, manganese, selenium, silica, arsenic, titanium, and fluorine. Proper ventilation must be provided.
9.6 Department-Specific Equipment
Departments are responsible for establishing safe operating and emergency response procedures and training for students and employees who operate or work near hazardous equipment. Examples of hazardous equipment include high-energy magnets, robots, injection molding machines, power presses, pressure vessels (see Pressurized System Safety Guide), lasers (see Laser Safety Guide), cryogenic gas storage, and delivery systems, etc.
9.7 Lockout of Hazardous Energy Sources
Employees authorized by the University to perform maintenance or repairs on machines and equipment in which the unexpected energization or startup could cause injury must be trained in accordance with the provisions of the University's Hazardous Energy Control Program for authorized employees. All other employees who operate or work near such machines or equipment must be trained in accordance with the provisions of the University's Hazardous Energy Control Program for affected employees.
Each department responsible for the operation of machines or equipment that could cause injury due to unexpected energization or startup during maintenance or repairs is responsible for establishing a written lockout procedure for each machine. Either the written lockout procedure or directions to its location must be posted where it will be visible from the point of operation of the equipment.
Chapter 10: Laboratory Safety
10.0 Laboratory Safety
The doors to laboratories utilizing hazardous equipment, toxic or flammable chemicals—and the doors to hazardous materials storage rooms—must be posted with an emergency response sign listing the nature of the hazards and name(s) and phone number(s) (work and home) of the individuals who are responsible for and/or familiar with the hazards and secured against unauthorized entry when the laboratory is unattended.
10.1 Flammable Liquids In Laboratories And Chemical Storage Rooms
The storage and use of flammable liquids in laboratories shall comply with the applicable provisions of the National Fire Protection Association Standard 45, Fire Protection For Laboratories Using Chemicals, 1997.
Refrigerators used for the storage of flammable liquids must be designed for this purpose and labeled as such. Domestic refrigerators may not be used for flammable liquids storage and must bear a label prohibiting flammable storage. Existing domestic refrigerators modified by Facilities may continue to be used for flammable storage as long as they are properly labeled. Explosion-proof refrigerators (also referred to as intrinsically safe) are intended for use in locations where the atmosphere outside the refrigerator is, or is reasonably likely to be, explosive and are typically not required in University laboratory environments.
Most laboratory fires are caused by ignition of flammable liquid spills or vapors that have spread from open containers near ignition sources such as hot plates and burners. Experiments and demonstrations should be planned in advance to ensure that sufficient distance is maintained between ignition sources and exposed flammable liquids (some solvent vapors can spread 10 feet or more along a bench top or floor).
The purpose of a flammable liquid storage cabinet is to delay the ignition of stored flammable liquids during a laboratory fire. It is not intended to contain or remove harmful or foul smelling vapors from poorly capped or contaminated containers. Venting of storage cabinets can reduce the level of fire protection and is discouraged except when the contents are so volatile and foul smelling that it is absolutely necessary. Venting must be accomplished according to the manufacturer's recommendations and in compliance with building fire safety codes and with the approval of Environmental Health and Safety and Facilities. The vent covers provided with the cabinet must be maintained in place at all times except when removed for the installation of a vent system.
Storage of flammable liquids in a laboratory shall be limited to that required for the operation of the laboratory. In addition, the following restrictions for laboratories and chemical storage rooms apply:
- Containers of Class IA liquids shall not exceed one pint capacity for glass containers, one gallon capacity for metal or approved plastic, or two gallons capacity for safety cans.
- Containers of Class IB liquids shall not exceed one quart capacity for glass containers, five gallons capacity for metal or approved plastic and safety cans.
- Containers of Class IC liquids shall not exceed one gallon capacity for glass containers, five gallons capacity for metal or approved plastic and safety cans.
- Containers of combustible liquids shall not exceed one gallon capacity for glass containers, five gallons capacity for metal or approved plastic containers and safety cans, and 60 gallons for metal drums.
- Not more than five gallons of Class I flammable liquids—or 10 gallons for Class I and combustible liquids combined—shall be stored outside of a UL-listed or FM-approved storage cabinet per 100 gross square feet of floor space.
- The maximum amount of flammable liquids stored inside and outside of approved storage cabinets may not exceed ten gallons of Class I flammable liquids —or 20 gallons for Class I and combustible liquids combined—per 100 gross square feet of space.
Approved Plastic—A plastic container approved for shipment of a particular flammable liquid under Chapter I, Title 49 of the Code of Federal Regulations.
Class IA flammable liquid—a liquid having a flash point below 73 F (22.8 C) and having a boiling point below 100 F (37.7 C).
Class IB flammable liquid—a liquid having a flash point below 73 F (22.8 C) and having a boiling point at or above 100 F (37.7 C).
Class IC flammable liquid—a liquid having a flash point at or above 73 F (22.8 C) and below 100 F (37.7 C).
Combustible liquid—a liquid having a flash point at or above 100 F.
10.2 Chemical Laboratories
10.2.1 Chemical Hygiene Plan
Chemical laboratories requiring a chemical hygiene plan and a chemical hygiene officer are those that use multiple chemical procedures or chemicals in a laboratory environment (i.e., where protective laboratory practices and equipment are available and in common use to minimize the potential for employee exposure to hazardous chemicals). Pilot plant operations that simulate production processes are exempt.
Departments with laboratories meeting the MIOSHA definition of a chemical laboratory must appoint a chemical hygiene officer who will assist in the development and implementation of a written department-specific chemical hygiene plan. The chemical hygiene plan will contain procedures for procurement, storage, use, and disposal of laboratory chemicals as well as the use of emergency equipment, personal protective equipment, engineering controls, and administrative controls for student and employee protection against laboratory hazards. The chemical hygiene plan must also contain laboratory-specific standard operating procedures, SOPs, for each chemical procedure. The written laboratory-specific SOPs must include a list of chemicals in use, the required personal protective equipment to be used for each procedure, and the safe work practices for each procedure. Spill response and waste disposal procedures should also be addressed in the SOP.
The department chemical hygiene officer shall be qualified by training or experience to provide technical guidance in the development and implementation of the provisions of the chemical hygiene plan. This should include a knowledge of the regulatory requirements for laboratory work as well as chemical safety and related industrial hygiene practices; supervisory experience; knowledge of department-specific chemical operations, inventories, hazards, purchasing and disposal practices, and safety equipment; and good written and verbal communication skills.
10.2.2 Chemical Labels and Material Safety Data Sheets
Chemical reagent containers must be labeled in accordance with Section 6.4 of this safety manual. Laboratory preparations must be labeled with the chemical identity of the contents, the date, and the identity of the owner. Chemical formulas are not acceptable as part of the identity description except for those that would be recognized and understood by faculty and staff outside the department. If the laboratory preparation is transferred to another location, the label must also include a primary hazard warning statement. A material safety data sheet or its equivalent may be required if the material is to be shipped off campus.
It is the responsibility of the person who receives an incoming chemical shipment to retain any material safety data sheets that are included. Each department may decide how and where material safety data sheets will be made available to students and employees as long as they are available whenever students or employees are on site. The Chemical Stores archive does not meet the requirement for availability, and therefore, may not be referenced on the required MIOSHA workplace notification poster, available from Environmental Health and Safety.
10.2.3 Fume Hoods
Fume hoods are critical components of the total safety and health protection system provided to students and employees working with hazardous materials, and they serve to protect the rest of the building occupants as well. However, a fume hood is only effective if it is designed, installed, maintained, and used properly. Fume hood users share responsibility for ensuring that the hoods are properly maintained by notifying the laboratory supervisor or department chair whenever a fume hood is not functioning properly. The user is also responsible for properly utilizing the hood. The following guidelines should be considered:
- Always work in a fume hood rather than on an open bench when using substances that have objectionable odors or emit toxic or flammable vapors.
- Verify proper air flow in the hood before starting work by checking the built-in flow meter or by holding a piece of paper towel near one of the air slots at the rear of the hood (learn to distinguish between the strength of the airflow caused by the blower and the flow caused by the “chimney effect” when the blower is not running). The sound of the blower motor is no assurance of hood operation because the drive belt may have failed.
- Remove everything from the hood that is not needed for the work to be performed.
- Avoid situations that could cause cross drafts in front of the hood, like open windows or doors, fans, pedestrian traffic, rapid movement of hands in or out of the hood, or rapid changes in sash position.
- Always work with the sash in the lowest possible position.
- Set up work at least six inches behind the plane of the sash.
- Adjust the hood baffles, if available, for the anticipated density of vapor emissions relative to that of the surrounding air. Emissions lighter than air, as a result of heating or low molecular weight, should correspond to shifting the baffle opening toward the top of the hood, and vapors heavier than air should be captured near the bottom.
- Use a support stand, if possible, to keep large containers and instruments a few inches above the work surface inside the hood to improve air flow around the setup.
- Avoid placement of cabinets or other objects in close proximity to the hood that might restrict the operator's ability to back away during an emergency or that cause turbulence in the airflow into the hood.
- Work with heated perchloric acid only in a properly functioning perchloric acid hood. Be sure you are familiar with the manufacturer's operating instructions.
- California hoods are designed to be operated with all doors fully closed.
- “Walk-in” hoods are not intended to be entered by the operator while in use; they are designed to permit the use of larger setups than a bench-top hood can accommodate. The same general principles of operation apply as for a bench-top hood.
- Pay attention to the most recent face velocity measurement posted on the hood. Do not work with highly toxic substances in a hood with a face velocity significantly less than 100 fpm.
- Use only intrinsically safe electrical instruments and connections in a hood when using heated or highly volatile flammable liquids and eliminate all other sources of ignition.
- The hood sash is not an explosion shield. If an explosion is the possible outcome of an instrument or operator failure, the experiment should be operated remotely or in a specially designed test cell or facility.
10.2.4 Chemical Purchases
Laboratory chemicals may not be delivered directly to an individual's office. All deliveries must be made to an area staffed during University operating hours by personnel who have been trained in accordance with the Michigan Tech Hazard Communication Plan and the Department of Transportation requirements. The delivery area and process must also provide for adequate security to prevent unauthorized access to the chemicals.
It is the policy of Purchasing to not use procurement cards to purchase laboratory chemicals.
10.3 Radiation Producing Equipment and Materials
10.3.1 Nuclear Regulatory Commission Regulated Materials
Work involving equipment or materials regulated by the Nuclear Regulatory Commission (NRC) is overseen by the University Radiation Safety Committee and the Radiation Safety Officer (RSO) in the Environmental Health and Safety Department. Requirements and procedures for the purchase, use, storage, and disposal of these materials are described in the University Radiation Safety Manual. Only employees specifically named in the University radioactive materials license may purchase these materials and each purchase must be approved by the RSO in advance. Faculty and staff wishing to engage in research involving radioactive materials should contact the RSO for information and assistance in obtaining any necessary approvals.
10.3.2 Ionizing Radiation Producing Equipment and Radioactive Materials
The installation and use of equipment which generates ionizing radiation is regulated by the Radiation Section of the Michigan Bureau of Health Systems. Radiative materials used as radiation sources in such equipment are also regulated by the Michigan Department of Environmental Quality if they are not regulated by the NRC. The University Radiation Safety Committee and RSO also oversee the use of these devices. Faculty and staff intending to purchase equipment that produces ionizing radiation—for example, X-ray diffraction machines, scanning electron microscopes, gas chromatographs, etc.—must first contact the RSO for information about registration, operation, and training.
Each department is responsible for ensuring that laser equipment is classified and labeled according to the requirements of the Federal Laser Product Performance Standard: Title 21 of the Code of Federal Regulations; Part 1000; [parts: 1040.10 and 1040.11]. Depending on the power output classification of the laser(s) in use, the department may need to designate a laser safety officer (LSO) to oversee the installation, use, and maintenance of equipment as well as the training of personnel. The University Laser Safety Guide contains important information from the Occupational Safety and Health Administration on laser safety.
10.4 Biological Laboratories
All activities involving the use of recombinant DNA/RNA must receive prior approval of the Institutional Biosafety Committee. Work involving infectious agents generally requiring Biosafety Level 2 or 3 practices must receive prior approval of the Biological Safety Committee. Activities requiring Biosafety Level 4 practices are forbidden at this time.
Activities involving the use of human body fluids, cell lines, and unfixed tissues require training and implementation of a written blood-borne infectious diseases exposure control plan.
Activities involving the use of nonhuman primate body fluids, cell lines, and unfixed tissues require training and documentation.
Activities that generate medical waste (sharps and potential or known human pathogens including zoonotic) require training and site registration with the Michigan Department of Health. Decontaminated biohazardous waste may not be placed in the regular trash without removal of all biohazard labels and markings. Over packing or covering a biohazard label is not acceptable.
Activities involving the release of plants or organisms into the environment require completion of a USDA permit application.
10.5 Shipping Hazardous Materials
Shipments of hazardous materials—such as explosives, compressed gases, flammable solids and liquids, oxidizers, toxic and infectious materials, radioactive materials, corrosive substances, and environmental pollutants—are regulated by the Department of Transportation (DOT), regardless of quantity. Employees who offer such materials for shipment, as well as those responsible for receiving shipments, must be trained in accordance with DOT regulations. Contact Environmental Health and Safety for information and assistance with training and shipments of materials that could potentially be regulated.
