Are you ready for wildfire smoke?
Wildfire Smoke 1
Washington State Department of Health-Temporary Worker Housing Program for Agricultural Employees.
Farmworkers are the backbone of Washington’s agricultural economy, yet they face some of the most dangerous conditions during wildfire smoke events. When smoke settles over our state, it does not just threaten the fields, it enters the places where workers and their families live. This includes Temporary Worker Housing (TWH). These conditions can quickly become hazardous, especially during Washington’s increasingly hot and dry summers.
The Washington State Department of Health (DOH) is committed to protecting the health of farmworkers and their families. As wildfire smoke and extreme heat intensify, preparation is essential. Employers, operators, and workers must work together to provide training and take practical steps to reduce smoke exposure by keeping indoor and outdoor air as clean and safe as possible.
Working long hours outdoors and poor indoor air quality make farmworkers especially vulnerable to wildfire smoke exposure. These risks can be reduced with preventative measures in place. Reduce the risk of smoke-related illnesses by taking simple actions such as providing:
Appropriate respiratory protection.
Plenty of drinking water.
Rest breaks in well-ventilated indoor spaces with clean, filtered air.
This bulletin provides some guidance and resources to help farmworker housing operators, employers, and workers prepare for wildfire smoke events, protect their health, and stay safe throughout the season.
Key points from How Wildfire Smoke Affects Your Body, CDC
Wildfire smoke is a mix of gases and fine particles from burning trees and plants, buildings, and other materials.
Wildfire smoke can reach far away from where the fires burn.
Wildfire smoke can make anyone sick, but certain groups of people have a greater risk.

Wildfire Smoke 2
Wildfire smoke contains fine particles, PM2.5, that can irritate eyes and lungs and worsen heart and lung disease. DOH’s Smoke From Fires webpage explains that the risk of severe health impacts is greater for people who work outdoors, people 18 years old and younger, and those with lung diseases like asthma or existing heart or circulatory problems. The Smoke from Fires webpage includes:

Factsheets for the public.
Protecting farmworkers and their families from the dangers of both heat and wildfire smoke is more important than ever. Please watch this Department of Labor and Industries safety expert, Chris Pyke, review the rules employers must follow and give tips to keep everyone safe: Washington Wildfire Smoke and Outdoor Heat Exposure Rules, Nonprofit Association of Washington.
