Q: I am looking for the respiratory mask to be used for powder coating. What type of mask should we use and are there any standards I need to follow?
A: In the United States, our National Institute of Occupational Safety and Health recommends the use of a dust mask that is rated as N95. This designation means the dust mask will remove 95% of particulate materials from the air that you breathe.
It is essential to fit the mask carefully on your face. Thick beards and narrow bridges on one’s nose can make fitting a bit of a challenge. If a person has a thick beard, they may have to trim it for better fit. And if they have a small face, there are other products available.
The NIOSH N95 page is here: https://www.cdc.gov/niosh/npptl/topics/respirators/disp_part/n95list1.html.
Please be aware that these masks are only good for protection from airborne particulates. If your operators handle cleaning solvents, a respirator with an activated carbon filter is necessary. NIOSH provides information on respirators acceptable for handling acetone here: https://www.cdc.gov/niosh/npg/npgd0004.html
Respirators can also be fitted with particulate filters to protect from powders and solvents.
