University Standard Operating Procedures

University Standard Operating Procedures (USOPs) provide detailed information about the safe use of hazardous chemicals in different situations. All University of Arizona laboratory workers must comply with any USOPs that apply to their work with hazardous chemicals. The hazards, control measures, spill, exposure procedures, and waste disposal requirements for each Hazard Class are described in specific Hazard Class USOPs. Other USOPs include "Unattended Reactions," "Proper Use of a Chemical Fume Hood" and "Use of Hazardous Chemicals in Animals."

All USOPs are included in Appendix B of the University Chemical Hygiene Plan and they are also available as separate PDF documents below.

Laboratory Standard Operating Procedures

Some procedures are specific to each laboratory so cannot be covered in the general University Standard Operating Procedures. These procedures must be documented as Laboratory Standard Operating Procedures (LSOPs) to address the specific chemical hazards and situations expected in the laboratory.

LSOPs are required for the use of hazardous chemicals with their own OSHA vertical standard (49 CFR 1900.1001 – 1910.1052). Examples of such chemicals include benzene, mercury, methylene chloride, and lead. LSOPs may also be required for specialized procedures or equipment in the laboratory that may present a unique hazard to laboratory workers, or that are meant to mitigate hazards presented to laboratory workers.  All laboratory specific LSOPs must be included in the Approval’s Laboratory Chemical Hygiene Plan (LCHP) and their relevance and effectiveness evaluated annually, with the rest of the LCHP.
