When using this unit as a Type C Supplied Air Respirator
DO NOT
•
Use any supply hose longer than 300 feet
•
Use more than 12 sections of supply hose in any combination.
•
Use other than North air supply hose approved for use with this unit, or
•
Use a quick-connect coupler at the air source without compensating for the pressure drop
by increasing the required pressure at least 1 and no more than 5 psig.
Each of these prohibited hose configurations will reduce air flow to the facepiece below the
required minimum, exposing the user to risk of serious injury, illness or death.
Be sure that all respirable air system piping, tubing, fittings and couplings are incompatible with
non-respirable gas systems. OSHA Regulation 29 CFR 1910.134, “Respiratory Protection” states
“Airline couplings shall be incompatible with outlets for other gas systems to prevent inadvertent
servicing of air line respirators with non-respirable gases or oxygen.
WARNING
The air supply must have the capacity to maintain the required pressure during respirator use.
DO NOT USE COMPRESSED OXYGEN IN THIS RESPIRATOR.
The air supply source must be constructed and situated so as to avoid entry of contaminated air
into the system. Suitable in-line filters must be installed to assure breathing air quality. If using an
oil-lubricated compressor, it must be equipped with either a high temperature alarm or a carbon
monoxide alarm, or both. If only a high temperature alarm is used, the air from the compressor
must be frequently tested, (as outlined in the OSHA Regulation 29 CFR 1910.134), for the pres-
ence of carbon monoxide to ensure that the air conforms to specification requirements for
breathing air.
WARNING
If the supplied air fails, open the cylinder valve and proceed to fresh air immediately,
