INSPECTION PROCEDURE EXACTLY. IF
THE END OF SERVICE INDICATOR ALARM
DOES NOT ACTUATE AS DESCRIBED IN
THIS INSTRUCTION, THE PURGE DOES NOT
ACTUATE AS DESCRIBED IN THIS INSTRUC-
TION OR ANY OTHER OPERATIONAL MAL-
FUNCTION IS NOTED, DO NOT USE THE
RESPIRATOR. REMOVE THE RESPIRATOR
FROM SERVICE AND TAG IT FOR REPAIR
BY AUTHORIZED PERSONNEL. FAILURE
TO PROPERLY IDENTIFY MALFUNCTIONS
MAY RESULT IN SERIOUS INJURY OR
DEATH.
WARNING
THE INFORMATION IN THIS INSTRUC-
TION IS MEANT TO SUPPLEMENT, NOT
REPLACE, THE INSTRUCTIONS, TRAIN-
ING, SUPERVISION, MAINTENANCE, AND
OTHER ELEMENTS OF YOUR ORGANIZED
RESPIRATORY PROTECTION PROGRAM.
SEE WARNING ON SECOND PAGE OF THIS
DOCUMENT. FAILURE TO HEED ANY WARN-
INGS IN THIS INSTRUCTION MAY RESULT IN
SERIOUS INJURY OR DEATH.
REGULAR OPERATIONAL INSPECTION
The following procedure shall be used when you first receive the respi-
rator and for daily or periodic inspection of the respirator. Respirators
in regular use must be inspected at the start of each use period and
during cleaning after each use. Respirators maintained for emergency
use must be inspected as frequently as required to assure the respirator
will function properly when required. The US Labor Department (OSHA),
pursuant to 29 CFR 1910.134, requires at least monthly inspection of
respirators maintained for emergency use. NIOSH recommends an
inspection for cylinder pressure at least weekly. The condition of stor-
age at your location or the regulations which apply to your respiratory
protection program may require more frequent periodic inspections.
If the respirator is equipped with a PASS device distress alarm, the follow-
ing procedures must be modified to include inspection of the PASS device.
Details of the REGULAR OPERATIONAL INSPECTION of the PASS device
are included in the user instructions for the PASS device. The part number
of the required PASS user instructions appears on the label on the battery
cover of the PASS device Sensor Module.
IF ANY DISCREPANCY OR MALFUNCTION IS NOTED DURING
THE INSPECTION, DO NOT USE THE RESPIRATOR. REMOVE
THE RESPIRATOR FROM SERVICE AND TAG IT FOR REPAIR BY
AUTHORIZED PERSONNEL.
WARNING
DAMAGED CYLINDERS MAY SUDDENLY
LEAK OR RUPTURE IF LEFT CHARGED WITH
COMPRESSED AIR. FAILURE TO INSPECT
FOR DAMAGE AND TO EMPTY THE AIR
FROM DAMAGED CYLINDERS MAY RESULT
IN SERIOUS INJURY OR DEATH.
INSPECTION OF THE BREATHING AIR CYLINDER
1. Visually inspect breathing air cylinder and valve assembly for physical
damage such as dents or gouges in metal or in composite wrapping.
Cylinders which show physical damage or exposure to high heat or
flame, such as paint turned brown or black, decals charred or miss-
ing, pressure gauge lens melted or elastomeric bumper distorted,
and cylinders which show evidence of exposure to chemicals such
as discoloration, cracks in the cylinder or the composite wrapping,
peeling of the outer layers of the composite wrapping and/or bulging
of the cylinder wall, shall be removed from service and emptied of
compressed air. Publications on compressed gas cylinder inspection
procedures are available from Compressed Gas Association Inc.,
1725 Jefferson Davis Hwy., Suite 1004, Arlington, VA 22202 (703-
412-0900).
2. Check the latest cylinder hydrostatic test date to ensure it is current.
The date of manufacture marked on the cylinder is also the date of
the first hydrostatic test. All breathing air cylinders used with SCOTT
AIR-PAK
75i
SCBA’s must be visually inspected regularly and hy-
drostatically tested at the required intervals by a licensed cylinder
re-tester. Intervals for hydrostatic testing are established in the ap-
propriate US Department of Transportation (DOT) specification or
applicable DOT exemption, or in the appropriate Transport Canada
(TC) Permit of Equivalent Level of Safety. Refer to the current revision
of
Safety Precautions for AIR-PAK Cylinders
, SCOTT P/N 89080-01,
available on request from SCOTT Safety. Composite fiber over-
wrapped cylinders must be tested up to their maximum life which, at
the time of the publication of this instruction, is 15 years from the date
of manufacture. It is the responsibility of your organized respiratory
protection program to arrange for visual inspection and hydrostatic
testing of cylinders by a licensed re-tester.
3. Check for damage of the cylinder valve hand wheel and the threads
on the cylinder valve outlet.
4. Check the relief valve (burst disc) for damage or dirt.
5. Check the cylinder pressure gauge for “FULL” indication. If cyl-
inder pressure is less than “FULL,” replace with a fully charged
cylinder.
WARNING
IF THE RESPIRATOR IS EQUIPPED WITH
A PASS DEVICE DISTRESS ALARM AND
IT FAILS TO FUNCTION IN ACCORDANCE
WITH THE INSTRUCTIONS CONCERNING
REGULAR OPERATIONAL INSPECTION SUP-
PLIED WITH THE DISTRESS ALARM, DO NOT
USE THE RESPIRATOR. REMOVE IT FROM
SERVICE AND TAG FOR REPAIR BY AUTHO-
RIZED PERSONNEL. FAILURE TO PROPERLY
IDENTIFY MALFUNCTIONS MAY RESULT IN
SERIOUS INJURY OR DEATH.
