FDNY G82 CERTIFICATE OF FITNESS HANDLING &
DISPENSING OF CARBON DIOXIDE (CO₂) EXAM
QUESTIONS WITH VERIFIED ANSWERS &
RATIONALES INSTANT DOWNLOAD GRADE A+.
Question 1
Carbon dioxide (CO₂) is classified as which type of gas?
A. Flammable gas
B. Toxic gas
C. Inert gas
D. Oxidizing gas
Correct Answer: B. Inert gas
Rationale: CO₂ is a non-flammable, inert gas, but it is an asphyxiant because it
displaces oxygen in enclosed spaces.
Question 2
What is the primary hazard associated with carbon dioxide in enclosed spaces?
A. Explosion
B. Fire
C. Oxygen displacement
D. Chemical burns
Correct Answer: C. Oxygen displacement
Rationale: Carbon dioxide displaces oxygen, which can cause dizziness,
unconsciousness, or death due to asphyxiation.
Question 3
Who is required to hold an FDNY G82 Certificate of Fitness?
A. Anyone working near CO₂ cylinders
B. Any restaurant employee
,C. Persons handling or dispensing CO₂ systems
D. Fire guards
Correct Answer: C. Persons handling or dispensing CO₂ systems
Rationale: FDNY requires a G82 Certificate of Fitness for individuals
responsible for handling, replacing, or dispensing carbon dioxide systems.
Question 4
Carbon dioxide cylinders must be stored:
A. Horizontally
B. With valves removed
C. Upright and secured
D. Near heat sources
Correct Answer: C. Upright and secured
Rationale: CO₂ cylinders must be stored upright and properly secured to
prevent tipping and valve damage.
Question 5
Which device is required in areas where CO₂ is dispensed?
A. Fire alarm pull station
B. Carbon monoxide detector
C. Carbon dioxide monitoring system
D. Smoke detector
Correct Answer: C. Carbon dioxide monitoring system

of dangerous concentrations.
Question 6
What is the maximum allowable CO₂ concentration before alarms activate?
A. 0.5%
B. 1.5%
,C. 3%
D. 5%
Correct Answer: B. 1.5%
Rationale: FDNY requires alarms to activate at 1.5% CO₂ concentration to
provide early warning.
Question 7
When a CO₂ alarm sounds, the certificate holder must FIRST:
A. Reset the alarm
B. Investigate the source
C. Evacuate the area
D. Call maintenance
Correct Answer: C. Evacuate the area

A leaking CO₂ cylinder should be:
A. Ignored if small
B. Tightened immediately
C. Removed to a safe location
D. Covered with a cloth
Correct Answer: C. Removed to a safe location
Rationale: Leaking cylinders pose an asphyxiation hazard and must be isolated
and handled safely.
