clothing that could melt, ignite and continue to burn when exposed to flames.10
To meet the CDC and OSHA guidance in areas where a flash fire hazard has been identified, employees must wear FR face cov- erings. FR face coverings will not melt, drip or burn when exposed to heat or flames. If you have identified a flash fire hazard and your employees are wearing FR garments, then they should also be wearing FR face coverings.
In addition to the general mask selection criteria noted previ- ously, consider the following when selecting an FR face covering:
Inherency. Inherently heat- and flame-resistant materials have FR protection that is built into the fibers and can’t be washed out or worn away. Is the protection inherent to the fabric?
Durability. Assuming the mask is reusable, how many wash cycles will it withstand? Will washing or decontamination compro- mise any FR properties of the mask?
Match your FR PPE
As new guidance continues to evolve, it is more important than ever—and can be even more challenging—to quickly adapt to the changing needs of workers during the COVID-19 pandemic. Re- member to evaluate the risk of exposure to the virus as well as haz- ards present in your work environment in order to protect workers effectively. And if you need assistance with navigating the chal- lenges you face, consult with an expert.
