Indoor Air at Work & COVID-19

A new fact sheet highlights how to improve the air quality indoors to reduce the risk of COVID-19.

The fact sheet provides links to a longer guidance document on indoor air quality and ventilation that Cal/OSHA requires employers to review, as well as to the updated Cal/OSHA Emergency Temporary Standard.

You will learn:

how to use ventilation to improve indoor air quality and why it’s important
tips if you have a mechanical heating, ventilation, and air conditioning (or HVAC) system
do’s and don’ts when using fans, and
helpful hints and links on portable air cleaning devices.

We have also developed user-friendly social media graphics and short videos that help to explain California ventilation requirements for preventing COVID-19. See the samples below or on our Tools for Workers webpages.
