Process Safety Management (PSM) 

The purpose of this rulemaking is to improve workplace safety and health at refineries. Catastrophic events at oil refineries across the U.S. have tragically claimed the lives of many workers — including 13 in Washington State since 1998. Six workers died from a Process Safety Management (PSM) related incident in 1998 at a petroleum refinery in Anacortes. In 2010, 7 more workers died when a heat exchanger used in the refining process at a petroleum refinery in Anacortes exploded and the fire engulfed the workers. These incidents have led to much discussion about what could have been done to prevent these tragedies.


On December 27th, 2023, L&I, Division of Occupational Safety and Health (DOSH) filed a Permanent Rulemaking (CR-103P) to adopt the updated requirements in Chapter 296-67 WAC Safety Standards for Process Safety Management of Highly Hazardous Chemicals relating to petroleum refineries.

In 2015, the Department of Labor & Industries (L&I) launched an effort to update the safety standards for process safety management of highly hazardous chemicals. A Process Safety Management Advisory Committee was established consisting of L&I staff, labor representatives, business representatives, and other community members.

The Committee held 10 meetings between September 21, 2015 and September 6, 2017, during which the initial draft rule language was developed and discussed. In August 2017, L&I filed a preproposal statement of inquiry (CR-101) initiating a rulemaking. Eleven stakeholder meetings to discuss the draft rule language were conducted between January 24, 2018 and December 4, 2018. On June 21, 2023, L&I filed a proposed rulemaking (CR-102) and held public hearings in August 2023. Finally, on December 27, 2023, L&I filed a Permanent Rulemaking (CR-103P) and the rules are effective December 27, 2024.
