INTRODUCTION
This comprehensive examination is designed to assess the essential knowledge, skills, and decision-making capabilities required for individuals
seeking the G-22 Certificate of Fitness for Torch Operations using Oxygen and Flammable Gases. The assessment evaluates a candidate’s
understanding of New York City Fire Code regulations, safe torch handling practices, mandatory fire watch duties, and emergency response
procedures. Consisting of highly structured multiple-choice and scenario-based questions, this exam emphasizes real-world application, hazard
identification, and compliance standards. Candidates must demonstrate critical thinking under simulated high-risk conditions to ensure the safety of
life and property across various operational settings.
SECTION ONE: QUESTIONS 1–100
Question 1
What is the minimum distance that all combustible materials must be moved away or protected from a torch operation site?
A. 10 feet
B. 25 feet
C. 35 feet
D. 50 feet
,🟢 C. 35 feet
🔴 RATIONALE: According to the FDNY Fire Code, all combustible materials must be relocated at least 35 feet away from the torch operations. If
relocation is impractical, the combustibles must be shielded with a fire-resistant shield or guard.
Question 2
A Certificate of Fitness holder performing torch operations notices a drop in pressure on the fuel gas regulator. What should be the immediate course
of action?
A. Increase the oxygen pressure to balance the flame
B. Shut down the torch immediately and check for leaks
C. Continue working until the cylinder is completely empty
D. Tighten the regulator connection with an oiled wrench
🟢 B. Shut down the torch immediately and check for leaks
🔴 RATIONALE: An unexpected drop in pressure indicates a potential leak or system malfunction. The operator must immediately extinguish the
torch and inspect the system. Oil or grease must never be used on gas connections due to spontaneous combustion risks.
Question 3
Who is primarily responsible for maintaining a continuous watch for fire during and after torch operations?
A. The torch operator
B. The building owner
C. The designated fire watch
D. The FDNY inspector
🟢 C. The designated fire watch
🔴 RATIONALE: The fire watch is explicitly tasked with monitoring the hot work area for sparks, slag, and fire. This individual must remain focused

Question 4
After the completion of hot work operations, how long must a fire watch remain at the work site to detect smoldering fires?
A. 15 minutes
B. 30 minutes
C. 45 minutes
D. 60 minutes
🟢 B. 30 minutes
🔴 RATIONALE: The FDNY Fire Code mandates that the fire watch remain at the site of torch operations for at least 30 minutes after work
,concludes to ensure no smoldering fires develop.
Question 5
When storing oxygen and fuel gas cylinders together, what is the minimum required separation distance if a fire-resistant barrier is not utilized?
A. 5 feet
B. 10 feet
C. 15 feet
D. 20 feet
🟢 D. 20 feet
🔴 RATIONALE: Oxygen cylinders in storage must be separated from fuel gas cylinders or combustible materials by a minimum distance of 20 feet
or by a noncombustible barrier at least 5 feet high with a fire-resistance rating of at least 30 minutes.
Question 6
Which of the following types of fire extinguishers is universally required at a hot work location utilizing a torch?
A. Class A water extinguisher
B. Class K wet chemical extinguisher
C. Minimum 2-A:20-B:C rated dry chemical extinguisher
D. Class D dry powder extinguisher
🟢 C. Minimum 2-A:20-B:C rated dry chemical extinguisher
🔴 RATIONALE: FDNY regulations mandate that a portable fire extinguisher with a minimum rating of 2-A:20-B:C be readily accessible within 30
feet of the hot work location.
Question 7
A torch operator observes that the hose connected to an acetylene cylinder has a deep crack that exposes the inner fabric fabric. What action is
required?
A. Wrap the cracked area tightly with electrical tape
B. Continue using it if no gas smell is detected
C. Replace the hose entirely before commencing work
D. Splice the hose using standard copper fittings
🟢 C. Replace the hose entirely before commencing work
🔴 RATIONALE: Damaged hoses are an extreme safety hazard and must be replaced immediately. Splicing or taping hoses used for hot work is
strictly prohibited under FDNY regulations.
, Question 8
What color is universally used to identify hoses carrying oxygen gas in a dual-line torch setup?
A. Red
B. Green
C. Black
D. Yellow
🟢 B. Green
🔴 RATIONALE: In standard torch setups, green indicates the oxygen line, while red indicates the fuel gas (such as acetylene or propane) line.
Question 9
Which regulatory body sets the standard for construction, testing, and marking of compressed gas cylinders used in New York City?
A. OSHA
B. Department of Transportation (DOT)
C. NFPA
D. FDNY Bureau of Fire Prevention
🟢 B. Department of Transportation (DOT)
🔴 RATIONALE: Compressed gas cylinders must be constructed, tested, and marked in accordance with United States Department of
Transportation (DOT) specifications.
Question 10
Under what condition is it acceptable to use a match or cigarette lighter to ignite a gas torch?
A. Only when a spark lighter is unavailable
B. If the gas pressure is set exceptionally low
C. It is strictly prohibited under any circumstance
D. When operating outdoors in high winds
🟢 C. It is strictly prohibited under any circumstance
🔴 RATIONALE: Matches or cigarette lighters must never be used to light a torch. The operator’s hand comes too close to the torch tip, risking
severe burns. A friction spark lighter (striker) must always be used.
Question 11
What is the specific legal function of a flashback arrestor installed on a torch system?
A. To regulate the discharge pressure of the cylinder
B. To prevent the reverse flow of gas and stop a flame from traveling back into the cylinder
