Hazardous chemical releases pose a significant threat to workers. The key provision of process safety management (PSM) is process hazard analysis (PHA), a careful review of what could go wrong and what safeguards must be implemented to prevent releases of hazardous chemicals. The following references help begin a PHA by recognizing process hazards.
29 CFR 1910.119, Process safety management of highly hazardous chemicals. OSHA Standard.
Appendix A, List of highly hazardous chemicals, toxics and reactives (Mandatory). Contains a listing of toxic and reactive highly hazardous chemicals which present a potential for a catastrophic event at or above the threshold quantity.
Chemical Reactivity Worksheet. National Oceanic and Atmospheric Administration (NOAA), Office of Response and Restoration. Provides information about the reactivity of substances or mixtures of substances.
U.S. Chemical Safety Board (CSB). The CSB is an independent federal agency charged with investigating industrial chemical accidents. Based on these investigations, the CSB makes recommendations for controlling hazards and preventing future incidents. These lessons learned are published in investigation reports and videos provided by CSB:
All other documents, that are not PDF materials or formatted for the web, are available as Microsoft Office® formats and videos and are noted accordingly. If additional assistance is needed with reading, reviewing or accessing these documents or any figures and illustrations, please also contact OSHA's Directorate of Technical Support and Emergency Management at (202) 693-2300.
