Over the last few years, California has experienced multiple wildfires and the Bay Area, including the UC Berkeley campus has been impacted by the smoke from those wildfires. Smoke from wildfires is made up of a mixture of gases and fine particles produced when wood and other organic materials burn. During smoke events these fine particles are carried in the smoke, creating unhealthy conditions for those who breathe it in. While some people, such as those with asthma, or lung or heart conditions may be more sensitive to these pollutants, the higher the concentration of particles in the air the more unhealthy it is for everyone who is exposed to these pollutants. You should check the air quality index (AQI) frequently. There are many sources, including the Bay Area Air Quality Management District and the EPA’s Airnow, which provides a helpful section on AQI Basics.
Should the AQI exceed 200 and should this high level be expected to continue, the UC Berkeley campus will send out a message to students, faculty, and staff stating that classes are canceled and campus buildings are closed.
During smoke events, you should:
- Close windows, doors, and other openings through which smoke can enter.
- Close fresh-air intake on Air Conditioning Units and run Air Purifiers if available.
- Try to stay indoors. If you need to venture outside wear a particle respirator like an N95 or KN95 mask.
