OSHA Alert: COVID-19 Guidance on the Use of Cloth Face Coverings while Working Indoors in Hot and Humid Conditions


During the COVID-19 pandemic, OSHA generally recommends that employers encourage workers to wear cloth face coverings at work to help reduce the spread of COVID-19. However, workers who wear cloth face coverings in hot and humid environments or while performing strenuous activities indoors, such as those in bakeries, kitchens, laundries, electric utilities, fire services, mills, foundries, manufacturing, and warehousing, can find cloth face coverings to be uncomfortable.

Employers should follow the below practices to protect against the spread of COVID-19 and the risk of heat-related illness.
