100 MCQs with Rationales — FDNY G-46
1.
Which of the following best describes a non-flammable compressed gas under FDNY G-46?
• A) A gas that will not ignite or support combustion, even under high pressure
• B) A gas that becomes flammable when mixed with air
• C) A gas always toxic
• D) A gas used only outdoors
Answer: A) A gas that will not ignite or support combustion, even under high pressure
Rationale: Non-flammable gases don’t burn or support combustion even if released under
pressure (e.g., oxygen, nitrogen, argon).
2.
Which document is essential for identifying hazards and safety precautions for a gas cylinder?
• A) SDS (Safety Data Sheet)
• B) Property deed
, Page 3 of 115
• C) Tax record
• D) Elevator inspection report
Answer: A) SDS (Safety Data Sheet)
Rationale: SDS provides hazard identification, handling precautions, and emergency info.
3.
What is the default requirement for storing full and empty gas cylinders?
• A) Upright and secured with chains or restraints
• B) Lying flat on the floor
• C) Stored only outdoors
• D) Soaked in water
Answer: A) Upright and secured with chains or restraints
Rationale: Cylinders must be stable to prevent falling or impact damage.
4.

special controls?
, Page 4 of 115
• A) Inside an egress path
• B) Outside in a secured cage
• C) In a well-ventilated storage room
• D) Near an exterior wall
Answer: A) Inside an egress path
Rationale: Storage in exit corridors or paths can block egress during emergency.
5.
When transporting cylinders within a facility, the correct practice is to:
• A) Use a cylinder cart with restraints
• B) Slide the cylinder along the floor
• C) Carry by the valve cap
• D) Roll on a hand truck sideways
