LOW PRESSURE AIR SUPPLY USE
The members of the Rapid Intervention Team must be thoroughly trained and familiar
with the identification and operation of each Low Pressure connection method and the
appropriate application of each. Use care when handling the Low Pressure Air Supply
Hose and Manifold.
Verify which SCOTT respirator options are in use in your respiratory protection program
and how to connect the SCOTT RIT-PAK III portable air supply unit to the equipment in
use by the program. The RIT-PAK III portable air supply may be configured with various
low pressure quick disconnect couplings to accommodate different respirator applications.
Understand how to identify and operate all couplings.
NOTE
THE END-OF-SERVICE ALARM ON THE RESPIRATOR MAY NOT OPERATE NORMALLY
WHEN BEING SUPPLIED BY THE RIT-PAK III PORTABLE AIR SUPPLY. A MEMBER OF
THE TEAM MUST MONITOR THE AIR SUPPLY FOR THE RESPIRATOR USER UNTIL
THE RESCUE IS COMPLETE.
On SCOTT self-contained breathing apparatus (SCBA) respirators, connection to the LOW
pressure air supply hose may be made to one of the following methods depending on how
the respirator is configured:
– To the SCOTT facepiece mounted regulator if it is equipped with an in-line
quick disconnect
– To the SCOTT Emergency Breathing Support System (EBSS or “Buddy
Breather”)
– To the Extended Duration supplied air airline connection on the respirator.
Additional ports are provided on the LOW pressure air supply hose manifold for the in-
stallation of other quick disconnect fittings. Refer to the INSTALLATION OF ALTERNATE
QUICK DISCONNECT COUPLINGS section of this instruction for details.
In addition, use of the optional Emergency facepiece and Emergency breathing regulator
provides another method of supplying breathing air to the respirator user. Refer to the
USE OF THE EMERGENCY FACEPIECE AND BREATHING REGULATOR section of
this instruction.
Every emergency situation is unique. The users of this equipment must be fully trained
to assess the situation and the risks involved and decide how best to use this equip-
ment.
Special instruction and care is required for use of this equipment. When the system is
pressurized, the Low Pressure hose can release compressed air at 160 psi. Compressed
air pointed at unprotected skin may cause transmission of air into the blood stream caus-
ing air embolism and other tissue damage. Compressed air introduced into a body cavity
may cause serious or fatal injury.
Always position the SCOTT RIT-PAK III portable air supply on a safe, flat, level surface
where the unit or cylinder will not shift or slide. Avoid direct contact with fire or flame or
other sources of heat.
Use care when handling the LOW pressure airline assembly to avoid snagging or tangling
of the hoses and misuse or damage which could result in partial or complete loss of
breathing air or the uncontrolled release of compressed air. Any damage to the hoses
such as cuts or breakage, or damage to the pressure reducer assembly or quick discon-
nects may result in uncontrolled air loss from the respirator.
