05.G.06 Fit testing.
Employees wearing respirators with tight-fitting face pieces [Supplied Air Respirators (SARs) and Self-Contained Breathing Apparatus (SCBAs) included] must be fit tested to ensure that selected respirators achieve a proper face-to-facepiece seal.
Use a SCBA in IDLH environments.
Fit testing must be performed before initial use of the selected respirator, whenever respirator size, make or model is changed, and at least annually. Fit testing requirements must comply with respiratory protection program requirements.
05.G.07 Airline Respirators (SARs and SCBAs).
If airline respirators are used, the following apply (excludes underwater diving SCBAs, see Section 30):
- All SARs or SCBA respirators must meet the Grade D Breathing Air requirements from ANSI/Compressed Gas Association Commodity Specification for Air;
- If an airline respirator is used in an environment that has the potential to become IDLH, the respirator must have an alternate source of breathing air for escape from the environment;
- If an airline respirator is used in an environment that has the potential to become IDLH, there must be a respirator air attendant to prevent the lines from becoming tangled or tied, to change the air supply tanks, and/or to confirm the air source (compressor or air supply tank manifold) is adequately working. If the air supply is interrupted, the attendant must notify the respirator users to leave the area where the respirators are required.
