INSPECTING THE RESPIRATOR COMPONENTS
P/N 595360-01 Rev G 202004 13
Inspecting the Breathing Air Cylinder
Inspecting the cylinder includes looking for physical damage, noting the hydrostatic test date, and inspecting the
cylinder valve, including the hand wheel, outlet, connector, and relief valve.
To inspect the breathing air cylinder
1 Visually inspect the breathing air cylinder and valve assembly for physical damage such as dents or gouges in the
metal or the composite wrapping.
Physical damage to breathing air cylinders from high heat, flame, or chemical exposure includes the following:
•
Discoloration or paint that has turned brown or black
•
Charred or missing decals
•
Melted pressure gauge lens
•
Distorted elastomeric bumper
•
Cracks in the cylinder or the composite wrapping
•
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 Air-Pak 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 “ Respirator
Testing ” on page 6.
3 Inspect the cylinder valve (see Figure 1-1 ).
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
dirt and debris.
d Check the relief valve (burst disc) for damage or dirt.
WARNING
Damaged cylinders may suddenly leak or rupture if left charged with compressed air. Failure to inspect
cylinders for damage and to empty the air from damaged cylinders may result in serious injury or death.
