Board of Supervisors
Susan S. Muranishi, County Administrator
September 9, 2020
After an unusually hot and smoky Labor Day weekend, we are now experiencing widespread haze and darkened skies caused by the wildfires. With the rapidly changing air quality conditions, we ask that you take simple health precautions and follow the guidelines noted below.
Please stay healthy and safe — we appreciate your ongoing commitment and service during this extraordinary year.
The Bay Area is experiencing widespread haze caused by wildfires, leading to darkened skies. The haze may be accompanied by poor air quality, and air quality conditions can change rapidly depending on where you are. Please visit www.baaqmd.gov or www.airnow.gov to monitor local air quality conditions in your area and indicators to stay indoors.
Take simple health precautions to self-monitor and check in with a supervisor should you experience changes to your work areas.
Unhealthy Air Quality Guidelines for Alameda County Employees
The best option for responding to unhealthy air quality conditions is to avoid exposure to outdoor air and stay indoors with the windows and doors closed as much as possible.
Air quality is expected to continue to change throughout the week. We will continue to monitor local air quality levels to assess the potential impacts and provide further updates as necessary.
While N95 respirators/masks may be useful in some cases, they are not a substitute for staying indoors during days when the air quality is unhealthy.
