Learn About Respiratory Protective Equipment

Learning what type of Respiratory Protective Equipment to use in certain environments will provide you with optimal protection, and keep you and your employees safe.

You can read this full guide provided by UNC, or read our brief below.

There are two main types of RPE:

Atmosphere Supplying Respirators:

Atmosphere supplying respiratory protective equipment provides fresh breathing air from an outside source.

There are Three types of Atmosphere Supplying Respirators:

Air Supplied Respirators

  • Make use of a hose to deliver clean, safe air Light weight, and can provide clean air for long periods of time.
  • Limits the range of user-mobility and may fail if hose gets damaged
  • Can be called airline respirators C
  • an be used during extended work periods in an atmospheres that are not immediately dangerous.

Combination Respirators

  • Have an auxiliary self contained air supply in case main supply fails
  • Can be used to enter small spaces
  • Can be used when work periods are long, and the worker may or may not be exposed to immediately dangerous atmospheres.
  • the self contained portion of the respirator is small because it is used when a quick escape is needed.

Self Contained Breathing Apparatus

  • Have a wearable clean air supply
  • does not restrict movement with a hose connection
  • Can provide air up to 4 hours (closed circuit type)
  • Open-circuit can provide air for only 30-60 minutes
  • Usually worn when the atmosphere are or may be immediately dangerous to life in health, and the worker only needs to be there in a short amount of time.


Air Purifying Respirator (APR): 

Air purifying respirators remove harmful contaminants by passing the air through an air purifying element. There are three kinds of air purifying respirators (view this article on air purifying respirators on the OSHA website):

Particulate Respirators:

  • Capture particles such as dust, mists, and fumes.
  • Does not protect against gasses and vapors

Combination Respirators

  • Capture particles such as dust, mists, and fumes, as well as gasses and vapors
  • Have filters for both particles and vapors
  • May be heavier than particulate respirators
