PPE - Respiratory Protection
There are two main types of respiratory protection: air-purifying respirators (APRs) and atmosphere-supplying respirators.
APRs have filters or cartridges that remove particles from the air. They include the following types, which you learned about in detail:
- Particulate respirators
- Gas and vapor respirators
- Combination respirators
Atmosphere-supplying respirators supply fresh air to the user. They include the following types, which you learned about in detail:
- Self-contained breathing apparatus (SCBA)
- Air-supplied respirators
- Combination respirators
Each type requires special care and has recommended schedules for cartridge changes.
