G60 Cylinder Storage and Transportation 2 — Questions and Answers
Question 1: When transporting fuel gas cylinders in a vehicle, what is required regarding ventilation?
- The vehicle must have an air freshener to mask gas odors
- Cylinders must be transported in an enclosed trunk only
- The vehicle must be adequately ventilated to prevent gas accumulation (Correct answer)
- No ventilation is needed if cylinders are upright
Correct answer: The vehicle must be adequately ventilated to prevent gas accumulation
Adequate ventilation is required when transporting cylinders in vehicles to prevent dangerous accumulation of any leaking gas.
Question 2: Which type of storage area is prohibited for flammable compressed gas cylinders?
- Outdoor fenced areas
- Dedicated indoor storage rooms with ventilation
- Basements or below-grade areas (Correct answer)
- Above-grade storage rooms with fire-rated walls
Correct answer: Basements or below-grade areas
Flammable gas cylinders must never be stored in basements or below-grade areas because heavier-than-air gases like propane can accumulate and create explosive concentrations.
Question 3: How should acetylene cylinders always be stored and used?
- Horizontally to prevent pressure loss
- At a 45-degree angle
- In an upright vertical position (Correct answer)
- Inverted for better gas flow
Correct answer: In an upright vertical position
Acetylene cylinders must always be stored and used upright because they contain acetone liquid solvent; tilting can cause acetone to flow into the regulator and cause equipment damage or fire.
Question 4: The temperature limit for cylinder storage areas is generally not to exceed:
- 75°F (24°C)
- 100°F (38°C)
- 125°F (52°C) (Correct answer)
- 150°F (66°C)
Correct answer: 125°F (52°C)
Cylinder storage areas should generally not exceed 125°F (52°C) to prevent dangerous pressure increases, though some standards specify 130°F; avoiding excessive heat is the key principle.
Question 5: When cylinders are not in use, the cylinder valve must be:
- Left open to check for leaks by smell
- Closed and the regulator depressurized (Correct answer)
- Left at half-open position
- Open with the regulator removed
Correct answer: Closed and the regulator depressurized
When not in use, cylinder valves must be fully closed and the regulator depressurized to prevent accidental gas release and equipment wear.
Question 6: What is the proper method for moving a large, heavy compressed gas cylinder short distances?
- Dragging it along the floor on its bottom edge
- Rolling it on its bottom edge in an upright position (Correct answer)
- Carrying it between two workers
- Using a rope harness around the valve area
Correct answer: Rolling it on its bottom edge in an upright position
Large cylinders may be rolled short distances on their bottom edge in an upright position, but they should never be dragged, carried by the valve, or dropped.
Question 7: Which area is a designated 'no smoking and no open flames' zone as a matter of regulation?
- Only the area directly adjacent to an active torch
- Only indoor storage rooms
- Within 10 feet of compressed gas cylinders at all times (Correct answer)
- Only when cylinders are being transported
Correct answer: Within 10 feet of compressed gas cylinders at all times
No smoking and no open flames are permitted within 10 feet of compressed gas cylinders at all times to prevent ignition of any leaking gas.
