The Washington State Department of Labor & Industries enacted emergency rules and amendments to protect outdoor workers from heat exposure and wildfire smoke.


Outdoor Heat Exposure

In addition to the existing rules for heat exposure, employers must now also:

  • Provide a sufficient and accessible amount of cool drinking water.
  • Provide access to shade or other opportunities to reduce body temperature.
  • Educate employees about preventative cool-down periods.
  • Provide training to employees about the requirements of the emergency rule.
  • When the temperature is 89 degrees Fahrenheit or higher, employers must: (1) mandate paid cool-down rest periods of 10 minutes every 2 hours; (2) create the ability for employees to communicate with their supervisor; and (3) observe employees for heat-related illness.


Employers should note these requirements are in addition to already enacted heat exposure rules. These amendments as well as the original requirements should be reviewed for compliance.


Wildfire Smoke

According to the rules, employers must monitor the worksite Air Quality Index (AQI). In the event the AQI is 69 or higher, employers must:

  • Have a written wildfire smoke response plan.
  • Determine employee smoke exposure levels before work and while smoke is present.
  • Train employees on wildfire smoke hazards.
  • Train supervisors on how to respond to health issues.
  • Inform employees of any available protective measures.


In the event the AQI is 101 or higher, employers must additionally:


  • Alert employees of smoke levels.
  • Provide respirators and encourage use.
  • Limit employee exposure where possible.
