Supply Protection Respirator

For protection from gases and vapors, employers should provide an atmosphere-supplying respirator or an air-purifying respirator (apr), providing the apr has an end-of-service-life indicator or a replacement schedule based upon objective data.
On the other hand, an atmosphere-supplying respirator that supplies breathable air from an air compressor through an air line can provide protection for extended periods. if the total concentration of atmospheric particulates is low, particulate filter air-purifying respirators can provide protection for long periods without the need to replace the filter.
Respirators and gas masks work with filtration cartridges to supply clean air when working in potentially hazardous environments. scba (self-contained breathing apparatus) draws high-quality breathable air from a compressed-air cylinder and delivers it to the attached face mask.
Service life means the period of time that a respirator, filter or sorbent, or other respiratory equipment provides adequate protection to the wearer. supplied-air respirator (sar) or airline respirator means an atmosphere-supplying respirator for which the source of breathing air is not designed to be carried by the user.
