What Does Powered Air-Purifying Respirator (PAPR) Mean?
A powered air-purifying respirator (PAPR) is a personal protective equipment device used to prevent a worker's exposure to atmospheric hazards. The PAPR protects the wearer by preventing him or her from inhaling contaminants.
A PAPR uses a battery-powered system to pull ambient air through a purifying device and into the user's breathing zone. A filter, cartridge, or canister in the PAPR is used to remove the atmospheric contaminants. Because the PAPR system uses ambient air, the PAPR may only be used in situations where the contaminants and their concentrations are known. Different PAPR systems are capable of filtering different types and concentrations of contaminants.
