RESPIRATORS & THEIR USES
AIR-PURIFYING RESPIRATORS
Many have filters, cartridges, or canisters that remove contaminants from the air by passing the ambient air through the air-purifying element before it reaches the user.
Particulate Respirator
* Captures particles in the air, such as dusts, mists, and fumes
* Does not protect against gases or vapors
* Generally becomes more effective as particles accumulate on the filter and plug spaces between the fibers
Combination Respirator
* Normally used in atmospheres that contain hazards of both particulates and gases
* Have both particulate filters and gas/vapor filters
Gas and Vapor Respirator
* Are normally used when there are only hazardous gases and vapors in the air.
* Uses chemical filters to remove dangerous gases or vapors and protect against specific gases or vapors, not
airborne particles
* Provides protection only as long as the filter’s absorbing capacity is not depleted
* Generally equipped with an end-of-service-life indicator (ESLI).
* If no ESLI is present, a change schedule is necessary

ATMOSPHERE-SUPPLYING RESPIRATORS
Supplied-Air Respirator (SAR)
* Makes use of a hose to deliver clean, safe air from a stationary source of compressed air
* Provides clean air for long periods of time and is light weight for the user
* Limits the range of user-mobility and may fail due to hose damage
* Are normally used when there are extended work periods required in atmospheres that ARE NOT immediately
dangerous to life and health (IDLH)
Combination Respirator
* Have an auxiliary self-contained air supply to be used if the primary supply fails
* The self-contained portion can be small since it only needs to supply enough air for escape
* Can be used for entry into confined spaces
Self-Contained Breathing Apparatus (SCBA)
* Consists of a wearable, clean-air supply pack
* Doesn’t restrict movement with a hose connection
* The closed-circuit type can provide air up to 4 hours
* The open-circuit type only provides air for 30 – 60 minutes
