Advice for working in smoky air

Dear employee,

You have probably noticed the smoky air in our region today. Wildfire smoke can cause a range of health problems, including chest pain, coughing, fast heartbeat, headaches, and asthma attacks. Some people need to be outdoors for their work or other responsibilities. With our current unhealthy air conditions, it’s recommended that you limit your time outdoors. If you are concerned about doing field work in these conditions, please consider these tips and guidance:

  • Talk to your supervisor about possible options to reduce the amount of time you spend outdoors by performing desk work or alternate work assignments on smoky days.
  • Conduct field work later this week if possible (smoke should improve later in the week)
  • The air quality level can change quickly, so check air quality conditions regularly and if possible, adjust your schedule to avoid travel and working outdoors during periods when air quality is the most impacted by smoke conditions (keep in mind air quality is typically the worst in the middle of the day during wildfire smoke).
  • If you must work outdoors, limit time outdoors to a minimum and find a safe location to breathe filtered air while maintaining social distancing during breaks from outdoor work. Due to the COVID-19 pandemic, it will be more difficult to find public spaces to take clean/cool air breaks this year.
  • Drink plenty of water.
  • If you have medical conditions that could be worsened by wildfire smoke, consult with your medical provider and speak with your supervisor to work out the best options for your work schedule on smoke days.
  • You may be able to use accrued vacation or comp time when there is wildfire smoke instead of reporting to your designated work location. You may request leave, subject to approval by your supervisor. If you have no leave accrued, your supervisor may approve leave without pay to cover absences. Please refer to HR Bulletin 2011-0009 County Operations During Emergency Situations and Inclement Weather to learn more.

It is not known how much protection cloth face coverings or surgical masks provide from wildfire smoke. N95/N100 masks can provide protection to some people when worn properly but can also worsen conditions for people with existing respiratory conditions. Due to COVID-19, N95/N100 masks may not be available and those available are in need by medical professionals. KN95 masks are available through your agency’s Safety Officer where needed. Safety Officers may contact Fleet Stores for masks at
