Describe the two types of respirators
What will be an ideal response?
There are two types of respirators: air filtering and air supplying. Air filtering respirators filter toxic particulates out of the air. To comply with 42 CFR Part 84, an air-filtering respirator must protect its wearer from the most penetrating aerosol size of particle, which is 0.3 microns aerodynamic mass in median diameter. If there is any question about the viability of an air-filtering respirator in a given setting, employees should use air-supplying respirators. This type of respirator works in much the same way as an air tank for a scuba diver. Air from the atmosphere is completely blocked out, and fresh air is provided via a self-contained breathing apparatus.
