Chapter 8: Writing Standard Operating Procedures
The OSHA/MIOSHA Laboratory Standard requires that written SOPs are developed for all laboratory work that involves hazardous chemicals or physical hazards. SOPs are written documents that provide step by step instructions for completing laboratory procedures. A well- written SOP will also include information about potential hazards associated with the procedure and how the risks associated with these hazards will be mitigated. For this reason, a hazard analysis is the first step in developing an effective SOP (see section 2.1 ). Laboratory-specific SOPs must be prepared by laboratory personnel who are knowledgeable and involved with the experimental process/or procedure. The laboratory supervisor/PI is ultimately responsible for approving SOPs regardless of who prepares them. Laboratory-specific SOPs for laboratory work involving hazardous chemicals and physical hazards will comprise Chapter 9 of the laboratory’s CHP. These SOPs must be followed without deviation by faculty, staff, and students working in the laboratory.
A template for developing laboratory-specific SOPs is provided below. Note: Some laboratory equipment may present special hazards that will require a written SOP to assure safety. A similar approach for developing equipment SOPs may be followed though outside the requirements of the CHP.
In addition to promoting safety and helping ensure consistent experimental results, SOPs can also be used as a tool for instruction and training in the laboratory. As a standardized document, a written SOP can be used to effectively communicate the risks associated with research in the laboratory, helping to ensure that one person is not over-trained while another is under-trained. A written SOP also provides for continuity in laboratory training, making sure that instructions are not distorted or weakened over time and by staff turn-over. SOPs should be updated as necessary and as part of the CHP should be included in annual lab-specific CHP training/retraining.
