REGULAR OPERATIONAL INSPECTION CONTINUED...
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 dis-
coloration, 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 SCBA's must be visually inspected regularly and hydrostatically
tested at the required intervals by a licensed cylinder retester. Intervals
for hydrostatic testing are established in the appropriate 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 overwrapped cylinders must be tested up to
their maximum life which, at the time of the publication of this instruc-
tion, 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 retester.
3. Check for damage of the cylinder valve hand wheel.
4. Verify that the CgA attachment coupling on the cylinder valve outlet
is undamaged and clean and free of dirt and debris.
5. Check the relief valve (burst disc) for damage or dirt.
6. Check the cylinder pressure gauge for "FuLL" indication. If cyl-
inder pressure is less than "FuLL," replace with a fully charged
cylinder.
RIC UAC CONNECTION INSPECTION
Inspect the RIC-uAC Connection as follows:
1. Remove the dust cap from the RIC uAC coupling on the respirator.
2. Visually inspect the coupling for dirt or damage. Remove any dirt or
contamination from the coupling.
3. If the RIC uAC coupling on the respirator appears damaged, remove
the respirator from service and tag for repair by authorized personnel.
4. If no damage is found, replace the dust cap.
