1. Which of the following is the primary hazard associated with non-
flammable compressed gases?
A. They burn rapidly when exposed to air.
B. They produce large amounts of smoke.
C. They can create pressure-related hazards if released suddenly.
D. They ignite at low temperatures.
Answer: C
Sudden release of compressed gas can create dangerous high-pressure
conditions, propel objects, or rupture equipment. Although the gases are non-
flammable, pressure remains the primary hazard.
2. A compressed gas cylinder should always be stored:
A. Lying on its side.
B. Standing upright and secured.
C. Upside down.
D. Hanging from a chain by the valve.
Answer: B
,Keeping cylinders upright and secured minimizes the risk of tipping, valve
damage, and accidental release of compressed gas.
3. The valve protection cap should remain in place:
A. Only while transporting the cylinder.
B. Whenever the cylinder is not connected for use.
C. Only when the cylinder is empty.
D. Only during outdoor storage.
Answer: B
The valve protection cap helps prevent valve damage whenever the cylinder is
not connected to equipment.
4. Why should cylinders be protected from physical damage?
A. To improve gas quality.
B. To reduce gas pressure.
C. Because damaged cylinders may fail or leak.
D. To prevent discoloration.
Answer: C
Physical damage may weaken the cylinder or damage the valve, increasing the
risk of leaks or catastrophic failure.
5. Empty cylinders should be:
A. Stored with full cylinders without identification.
B. Clearly marked and stored separately when practical.
C. Left outdoors without protection.
D. Stored horizontally.
Answer: B
,Clearly identifying empty cylinders helps prevent confusion, improves inventory
control, and promotes safe handling.
6. Which action is appropriate when moving a compressed gas cylinder?
A. Roll it on its side across the floor.
B. Drag it by the valve.
C. Use a suitable cylinder cart with the cylinder secured.
D. Lift it by the valve cap.
Answer: C
Using an approved cylinder cart reduces the risk of dropping or damaging the
cylinder.
7. Storage areas for compressed gas cylinders should be:
A. Poorly ventilated.
B. Well ventilated.
C. Completely enclosed.
D. Filled with combustible materials.
Answer: B
Good ventilation reduces the risk of hazardous gas accumulation if a leak occurs.
8. Before connecting a regulator to a cylinder, an operator should first:
A. Remove all warning labels.
B. Inspect the cylinder and regulator for damage.
C. Lay the cylinder on the floor.
D. Heat the cylinder.
Answer: B
, Inspecting the cylinder and regulator helps identify damage or defects before
use.
9. Why is proper cylinder labeling important?
A. It improves cylinder appearance.
B. It identifies the gas and associated hazards.
C. It reduces gas pressure.
D. It prevents corrosion.
Answer: B
Proper labeling ensures personnel know the cylinder contents and applicable
safety precautions.
10.If a compressed gas cylinder is found leaking and it cannot be stopped
safely, the appropriate action is to:
A. Ignore the leak.
B. Attempt to weld the cylinder.
C. Follow emergency procedures and isolate the area.
D. Paint over the leak.
Answer: C
Personnel should follow established emergency procedures, isolate the hazard,
and notify the appropriate personnel rather than attempting unsafe repairs.
