Inspecting The Ric/Uac Connection - 3M SCOTT AIR-PAK X3 PRO Operating & Maintenance Instructions

•
Peeling of the outer layers of the composite wrapping
•
Bulging of the cylinder wall
If a cylinder shows any of the physical defects listed, remove it from service and empty it of compressed air.
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 cyl-
inders used with 3M Scott Fire & Safety SCBAs must be visually inspected regularly and hydrostatically tested at
the required intervals by a licensed cylinder re-tester. For more information about hydrostatic testing, see
"Appendix F: Respirator Testing" on page

Publications on compressed gas cylinder inspection procedures are available from Compressed
Gas Association Inc.
3 Inspect the cylinder valve (see
a Check for damage of the cylinder valve hand wheel.
b Inspect the cylinder valve outlet for damage.
c Verify that the CGA threads or Snap-Change connector on the cylinder valve outlet is undamaged and free of

NOTE
Do not use tools to close the cylinder valve. Over-tightening the cylinder valve may cause damage that could
result in air leaking from the cylinder.
4 Check the cylinder pressure gauge. If the cylinder is less than full, replace it with a fully charged cylinder.
For information about charging cylinders, see the current revision of Safety Precautions for Air-Pak Cylinders (P/N
