Under OSHA PSM, a Pre-Startup Safety Review (PSSR) is required before introducing a highly hazardous chemical to a process when:
Answer: A new facility is started up or a significant modification has been made to an existing process
PSSR is required for new facilities and when modifications are significant enough to require a change in the process safety information, ensuring all elements are in place before startup.
OSHA PSM requires employers to investigate incidents that resulted in or could reasonably have resulted in a catastrophic release. The investigation must begin:
Answer: Within 48 hours of the incident
29 CFR 1910.119(m) requires that incident investigations be initiated as promptly as possible, but no later than 48 hours following the incident.
Which of the following is NOT one of the 14 elements of OSHA's Process Safety Management standard?
Answer: Environmental Impact Assessment
Environmental Impact Assessment is an NEPA requirement for federal actions, not an element of OSHA's PSM standard, which focuses on preventing catastrophic chemical releases at fixed facilities.
Under PSM, how long must employers retain the five most recent compliance audit reports?
Answer: Until the next audit is completed
29 CFR 1910.119(o)(3) requires employers to retain the two most recent compliance audit reports, not a set number of years — they must be kept until replaced by newer audits.
The 'consequence analysis' component of a PSM hazard assessment typically evaluates which of the following?
Answer: The potential impacts of a release including toxic cloud dispersion and blast overpressure zones
Consequence analysis models the physical effects of accidental releases, such as vapor cloud dispersion, explosion blast zones, and thermal radiation, to understand potential harm to workers and the public.
In PSM, the term 'highly hazardous chemical' refers to:
Answer: A substance with toxic, reactive, flammable, or explosive properties listed in Appendix A or B of 29 CFR 1910.119
Under PSM, highly hazardous chemicals are those listed in 29 CFR 1910.119 Appendix A (with threshold quantities) or flammable liquids/gases in Appendix B that pose significant hazards.
Which PSM element requires employers to develop written safety and health procedures for each task involving highly hazardous chemicals and make them accessible to employees?
Answer: Operating Procedures
Operating Procedures under PSM must cover steps for each phase of operation, operating limits, safety and health considerations, and safety systems, and must be readily accessible to employees.
