F60 Gas Cylinder Storage and Handling 1 — Questions and Answers
Question 1: When storing oxygen and fuel gas cylinders without a firewall, what is the minimum required separation distance?
- 10 feet
- 15 feet
- 20 feet (Correct answer)
- 25 feet
Correct answer: 20 feet
OSHA and FDNY require oxygen and fuel gas cylinders to be stored at least 20 feet apart when not separated by a non-combustible barrier.
Question 2: What is the minimum height required for a non-combustible barrier used as an alternative to the 20-foot separation between oxygen and fuel gas cylinders?
- 3 feet
- 4 feet
- 5 feet (Correct answer)
- 6 feet
Correct answer: 5 feet
A non-combustible, non-porous barrier at least 5 feet high satisfies the separation requirement between oxygen and fuel gas cylinders.
Question 3: How must compressed gas cylinders be positioned when stored or in use?
- On their side to prevent rolling
- Upright and secured against tipping (Correct answer)
- At a 45-degree angle for stability
- Upside down to protect the valve
Correct answer: Upright and secured against tipping
Cylinders must be stored upright with valves at the top and secured with chains or straps to prevent accidental tipping.
Question 4: Which protective device must remain on a compressed gas cylinder whenever the regulator is not attached?
- Pressure relief valve
- Flow control cap
- Valve protection cap (Correct answer)
- Dust cover seal
Correct answer: Valve protection cap
The valve protection cap guards the cylinder valve from physical damage during handling and transport and must always be in place when the regulator is removed.
Question 5: How must empty compressed gas cylinders be handled on a job site?
- Stored together with full cylinders to save space
- Stored in the same rack but on a lower shelf
- Stored separately from full cylinders and marked 'empty' (Correct answer)
- Left anywhere on site since they pose no hazard
Correct answer: Stored separately from full cylinders and marked 'empty'
Empty cylinders must be segregated from full cylinders and clearly marked as empty to prevent misuse and maintain safe inventory control.
Question 6: What is the maximum temperature at which compressed gas cylinders should be stored?
- 75°F (24°C)
- 100°F (38°C)
- 125°F (52°C) (Correct answer)
- 150°F (66°C)
Correct answer: 125°F (52°C)
Storage temperatures exceeding 125°F (52°C) can raise internal cylinder pressure to dangerous levels and risk catastrophic failure of the vessel.
Question 7: Which method of moving compressed gas cylinders is strictly prohibited?
- Using a hand truck or cylinder dolly
- Rolling the cylinder on its bottom rim for short distances
- Dragging or sliding the cylinder along the ground (Correct answer)
- Tilting the cylinder slightly while using a dolly
Correct answer: Dragging or sliding the cylinder along the ground
Dragging or sliding cylinders can damage the valve, create friction sparks, or cause the cylinder to fall, all of which are serious safety hazards.
