29 CFR 1910.119 Process Safety Management of Highly Hazardous Chemicals applies to companies that deal with what quantity of any of the 130 chemicals on the Toxic/Reactive list?

• A. 10,000 lbs and more
• B. 1,000 lbs and more
• C. 100 lbs and more
• D. 50,000 lbs and more

Answer: (A)

Process Safety Management applies to a facility whenever a highly hazardous chemical is present in a process at or above the threshold quantity defined for that chemical. For the Toxic/Reactive List, the threshold quantity used in OSHA’s Appendix A is typically 10,000 pounds. That means if a process contains 10,000 pounds or more of any one of the listed chemicals, the PSM requirements come into play, covering elements like hazard analysis, operating procedures, training, mechanical integrity, and change management. The other quantities shown in the options are not the universal trigger for most chemicals on that list, which is why the 10,000-pound threshold is the best answer.
