Wildfire Smoke Workplace Safety & Health Rulemaking

L&I received a petition and is considering adding new wildfire smoke in the workplace rules to Chapter 296-62, WAC, General Occupational Health Standards. See all the rulemaking activity for wildfire smoke on our L&I Rulemaking page.


L&I has filed the Preproposal (CR-101) to start the formal process for this permanent rulemaking. Public meetings for this rulemaking are scheduled for early October, 2022 (see the sections below for more information). An emergency rule, separate from the permanent rulemaking, was effective 6/15/2022 until 9/29/2022.

Learn more about our rulemaking process and terminology.


L&I recognizes the hazard of wildfire smoke exposure is increasing every year and is now potentially presenting important health risks to all outdoor workers including those in construction and agriculture. One other state has adopted temporary and permanent workplace safety and health rules regarding wildfire smoke.

L&I has received a petition for rulemaking on this topic as well. As suggested by a petitioner, in the midst of widespread wildfires and a global pandemic, workers continue to perform essential duties. It is imperative that significant steps be taken to ensure the protection of these workers, especially given the increasing intensity of wildfire outbreaks over the years and the likelihood that they will continue in years to come.

Wildfire smoke presents hazards that employers and workers in affected regions must understand. Smoke from wildfires contains chemicals, gases and fine particles that can harm health. Proper protective equipment, exposure controls, and training are needed for employees working in wildfire regions.

Some of the issues that may be addressed are:

  • Identification of harmful exposures;
  • Communication;
  • Training and instruction;
  • Control of harmful exposures
