Protecting outdoor workers from wildfire smoke

Guidance for employers and outdoor workers

PRESS RELEASE
August 13, 2025

When smoke is in the air, take precautions to reduce exposure to wildfire smoke.

Employers and outdoor workers operating in areas with high levels of wildfire smoke should frequently monitor air quality conditions in their area and take steps to reduce smoke exposure, including relocating or rescheduling work tasks to smoke-free or less smoky areas and taking frequent breaks in smoke-free areas.

Reducing exposure to outdoor workers:

Check the air quality and encourage employees to sign up for emergency alerts

Smoke levels can change a lot during the day; if possible, wait until air quality is better before being active outdoors. Keep employees informed about air quality conditions, safety measures, and any changes to work plans.

Limit physical activity

Take it easier when smoke is in the air to reduce how much smoke is inhaled. When indoors, take steps to keep indoor air cool and clean. Encourage breaks and provide access to clean air spaces.

Choose a mask that will help protect yourself from smoke

It is important to know that cloth masks will not protect from wildfire smoke. N95 masks can provide protection from wildfire smoke. Consult your physician if you are uncertain about which type of mask is right for you or your work environment.

Reschedule outdoor work tasks if possible

Reschedule outdoor work tasks and activities to a time when air quality improves. If outdoor tasks and activities cannot be rescheduled and must be conducted when air quality is poor, it is recommended that individuals reduce smoke inhalation by:

  • Limiting the time spent outdoors by only performing essential activities.
  • Taking frequent breaks indoors in places where the air is clean, especially during periods with high outdoor levels of wildfire smoke.
  • If you must work outdoors, wear an N95 mask.

    • Note: Some areas may have regulations to reduce smoke exposure for outdoor workers.

    Monitor symptoms

    Wildfire smoke can make you sick. Breathing in smoke can affect you right away, causing coughing, trouble breathing, wheezing, asthma attacks, stinging eyes, and other symptoms.
