G60 Cylinder Storage and Transportation 1 — Questions and Answers
Question 1: When storing compressed gas cylinders, they must be secured in an upright position using what type of device?
- Rope or twine
- Chain, strap, or bracket (Correct answer)
- Adhesive tape
- Wooden wedges
Correct answer: Chain, strap, or bracket
Cylinders must be secured with chains, straps, or brackets to prevent them from falling and causing valve damage or injury.
Question 2: What is the minimum distance that flammable gas cylinders (such as propane or acetylene) must be stored from oxidizing gas cylinders (such as oxygen) when not in use?
- 5 feet
- 10 feet
- 20 feet (Correct answer)
- 25 feet
Correct answer: 20 feet
OSHA and NFPA standards require flammable gas cylinders to be stored at least 20 feet from oxidizing gas cylinders, or separated by a fire-resistant barrier at least 5 feet high.
Question 3: Which label or marking identifies a cylinder that has been condemned and must not be refilled or used?
- A green tag
- An 'X' marked in chalk
- A red or condemned tag/stamp (Correct answer)
- A yellow caution sticker
Correct answer: A red or condemned tag/stamp
A condemned cylinder is typically marked with a red tag or 'CONDEMNED' stamp by the cylinder owner or inspection authority, prohibiting further use or refilling.
Question 4: When transporting a compressed gas cylinder on a hand truck or cart, the valve protection cap must be:
- Removed to check pressure during transit
- Kept in place at all times (Correct answer)
- Replaced with a regulator for efficiency
- Left optional at the operator's discretion
Correct answer: Kept in place at all times
The valve protection cap must always remain in place during transport to protect the valve from impact damage that could turn the cylinder into a projectile.
Question 5: Compressed gas cylinders stored outdoors must be protected from:
- Wind only
- Direct sunlight and temperature extremes (Correct answer)
- Rain but not snow
- All weather conditions by fully enclosing them
Correct answer: Direct sunlight and temperature extremes
Cylinders stored outdoors must be shielded from direct sunlight and extreme temperatures to prevent pressure buildup and material degradation.
Question 6: What action should be taken before moving a cylinder that has a regulator attached?
- Open the valve fully to relieve pressure
- Remove the regulator and replace the valve cap (Correct answer)
- Lay the cylinder on its side for stability
- Increase the regulator pressure to safe travel level
Correct answer: Remove the regulator and replace the valve cap
Before moving a cylinder, the regulator must be removed and the valve protection cap reinstalled to prevent regulator damage and accidental gas release.
Question 7: Empty cylinders in storage should be:
- Stored horizontally to save space
- Left open so no one mistakes them for full
- Marked 'MT' or 'EMPTY' and stored separately from full cylinders (Correct answer)
- Discarded immediately after use
Correct answer: Marked 'MT' or 'EMPTY' and stored separately from full cylinders
Empty cylinders must be clearly marked 'MT' or 'EMPTY' and kept separate from full cylinders to prevent confusion and ensure proper handling.
