Which regulation number addresses Process Safety Management of Highly Hazardous Chemicals?

• A. 29 CFR 1910.119
• B. 29 CFR 1910.100
• C. 29 CFR 1926.400
• D. 29 CFR 1910.1200

Answer: (A)

Process Safety Management of Highly Hazardous Chemicals is established in OSHA’s rule at 29 CFR 1910.119. This regulation creates a comprehensive program to prevent or minimize catastrophic releases of highly hazardous chemicals by requiring a coordinated set of elements. It asks facilities to maintain detailed process safety information, perform a thorough process hazard analysis, develop and follow robust operating procedures, provide thorough training, ensure mechanical integrity of equipment, manage changes to processes, investigate incidents, prepare emergency planning and response measures, and conduct regular audits. The standard applies to processes involving highly hazardous chemicals above certain quantities and holds employers accountable for maintaining safe operating conditions around those processes.

Other regulations listed govern different safety topics. For example, 29 CFR 1910.1200 focuses on Hazard Communication—labeling and safety data sheets so employees understand chemical hazards. The general construction-related standard (29 CFR 1926.x) addresses safety requirements specific to construction activities, not process safety management. The 29 CFR 1910.100 set covers permissible exposure limits for hazardous substances, which is about exposure levels rather than the management system for preventing large releases.
