INTRODUCTION
THE PURPOSE OF THIS ASSESSMENT IS TO EVALUATE THE PROFICIENCY AND READINESS OF
CANDIDATES SEEKING THE FDNY G82 CERTIFICATE OF FITNESS. THIS EXAM MEASURES
COMPREHENSIVE KNOWLEDGE REGARDING THE SAFE HANDLING, STORAGE, AND DISPENSING OF
CARBON DIOXIDE USED IN BEVERAGE DISPENSING AND OTHER COMMERCIAL APPLICATIONS. THE
ASSESSMENT IS COMPRISED OF MULTIPLE-CHOICE AND SCENARIO-BASED QUESTIONS DESIGNED TO
TEST BOTH THEORETICAL UNDERSTANDING AND PRACTICAL DECISION-MAKING SKILLS. EMPHASIS IS
PLACED ON REAL-WORLD APPLICATION, ADHERENCE TO NEW YORK CITY FIRE CODES, AND THE
ABILITY TO RESPOND EFFECTIVELY TO HAZARDOUS SITUATIONS. CANDIDATES MUST DEMONSTRATE
A COMMITMENT TO SAFETY STANDARDS TO ENSURE THE PROTECTION OF PERSONS AND PROPERTY.
SECTION ONE: QUESTIONS 1–100
, 1. What is the primary role of the G82 Certificate of Fitness holder?
A. To repair high-pressure CO2 leaks in public streets
B. To oversee the safe handling and dispensing of CO2
C. To manufacture CO2 cylinders for commercial sale
D. To design fire suppression systems for commercial kitchens
🟢 B. To oversee the safe handling and dispensing of CO2
🔴 RATIONALE: The COF holder is responsible for ensuring that the handling, storage, and dispensing of CO2
within a facility comply with FDNY fire code safety standards.
2. At what concentration level does Carbon Dioxide (CO2) become immediately dangerous to life and health
(IDLH)?
A. 1,000 ppm
B. 5,000 ppm
C. 40,000 ppm
D. 500 ppm
🟢 C. 40,000 ppm
🔴 RATIONALE: While the OSHA PEL is lower, 40,000 ppm (4%) is considered the IDLH level where CO2 can
cause rapid asphyxiation and unconsciousness.
3. Carbon Dioxide is considered which of the following?
A. Flammable gas
B. Oxidizing gas
,C. Simple asphyxiant
D. Corrosive liquid
🟢 C. Simple asphyxiant
🔴 RATIONALE: CO2 displaces oxygen in the air. In poorly ventilated spaces, this displacement can lead to
oxygen deficiency and suffocation.
4. Which FDNY permit is required for the storage of CO2 in excess of 4,500 standard cubic feet?
A. G82 Permit
B. Site-specific Fire Code Permit
C. General Liability Permit
D. Hazardous Material Transportation Permit
🟢 B. Site-specific Fire Code Permit
🔴 RATIONALE: Facilities storing large quantities of compressed gases (exceeding specific thresholds) must
obtain a site-specific permit from the FDNY.
5. How should CO2 cylinders be stored to prevent physical damage?
A. Laying horizontally on the floor
B. In an upright position and secured
C. Stacked on top of each other
D. Suspended from the ceiling by chains
🟢 B. In an upright position and secured
, 🔴 RATIONALE: Cylinders must be stored upright and secured (using chains or straps) to prevent them from
falling, which could shear the valve and turn the cylinder into a projectile.
6. What is the specific gravity of CO2 compared to air?
A. 0.5 (lighter than air)
B. 1.0 (same as air)
C. 1.5 (heavier than air)
D. 2.5 (extremely heavy)
🟢 C. 1.5 (heavier than air)
🔴 RATIONALE: CO2 is approximately 1.5 times heavier than air, meaning it will settle in low-lying areas, pits,
and basements.
7. Which device is required to reduce high cylinder pressure to a safe working pressure for dispensing?
A. Flow meter
B. Pressure regulator
C. Check valve
D. Manifold bypass
🟢 B. Pressure regulator
🔴 RATIONALE: High-pressure CO2 cylinders contain pressures up to 800+ psi; a regulator is essential to bring
this down to usable levels (e.g., 20-100 psi).
8. If a CO2 leak is suspected in a basement, what is the first action a G82 holder should take?
