Scott RIT-PAK III Operating And Maintenance Instructions Manual page 23

BASIC PRINCIPLES OF LOW PRESSURE AIR SUPPLY USAGE
1. Use only in accordance with your respiratory protection program. The
SCOTT RIT-PAK III portable air supply is to be used only for aid in evacuat-
ing a respirator user from an area requiring respiratory protection.
2. Perform REGULAR OPERATIONAL INSPECTION procedure of the SCOTT
RIT-PAK III portable air supply as described in these instructions.
3. Before connecting to respirator user, ensure that the SCOTT RIT-PAK III
portable air supply is away from sources of heat or flame and secured on a
safe, flat, level surface where the unit or cylinder will not shift or slide. Handle
the air hose in a manner which will prevent a sudden or unexpected pull on
the air hose from moving or damaging the SCOTT RIT-PAK III portable air
supply.
4. Assign a trained person to monitor the air gauge on the RIT-PAK III portable
air supply.
a) The person monitoring the air gauge must be instructed to alert the
Rapid Intervention Team when the air pressure has been reduced to a
predetermined value. That predetermined value, for example, 1/4 Full
(approximately 500 psi for a 2216 cylinder OR 1000 psi for a 4500 psi
cylinder OR 1200 psi for a 5500 psi cylinder), must be set after considering
all conditions of respirator use and in conformance with your organized
respiratory protection program.
b) Be certain the person assigned to monitor the pressure gauge of the air
supply cylinder has an effective means of communicating with the Rapid
Intervention Team. See the SERVICE LIFE section on page four of this
instruction.
5. Verify that the respirator user's air supply cylinder is properly installed with
the cylinder coupling connected to the cylinder to prevent any loss of breath-
ing air when the SCOTT RIT-PAK III portable air supply is connected.
a) If the respirator user's air supply cylinder is open, air will continue to
be supplied from that cylinder until the supply pressure drops below
the supply pressure from the Low Pressure airline assembly.
b) If the respirator user's air supply cylinder is closed, the only source of
breathing air will be from the SCOTT RIT-PAK III portable air supply.
6. Connect the air supply hose of the SCOTT RIT-PAK III portable air supply
to the respirator being used by the individual being evacuated. Refer to the
LOW PRESSURE AIRLINE CONNECTIONS section of this instruction for
details of possible airline connections.
7. Refer to the LOW PRESSURE AIRLINE CONNECTION for details of when to
open air supply cylinder valve of the SCOTT RIT-PAK III portable air supply.
Valve must be fully open for proper use.
8. Secure the LOW pressure airline assembly to the respirator user's person,
check that facepiece fit is secure, and transport in accordance with your
organized respirator program.
9. If, during use of the respirator, breathing becomes difficult for the respirator
user, the air supply stops or any other difficulty is encountered, identify and
correct the problem immediately. If necessary, find another source of breath-
ing air for the respirator user until the evacuation can be completed. Leave
the area requiring respiratory protection as quickly as possible as prescribed
by your organized respiratory protection program.

TO MONITOR THE AIR GAUGE OF THE
CYLINDER AND VALVE ASSEMBLY USED
WITH THE SCOTT RIT-PAK III PORTABLE
A I R S U P P LY A N D / O R FA I L U R E TO
MAINTAIN EFFECTIVE COMMUNICATIONS
WITH THE RESPIRATOR USER MAY
RESULT IN SUDDEN AND UNEXPECTED
