SECTION 1: TORCH OPERATIONS & CUTTING EQUIPMENT Q1 – Q10
══════════════════════════════════════
Question 1 of 50
At a Brooklyn construction site, a welder is preparing to perform oxy-acetylene cutting on
steel beams. The site superintendent wants to know the minimum distance required between
the cutting operation and nearby stacks of plywood and wooden scaffolding materials.
According to NYC Fire Code requirements for cutting and welding operations, what is the
correct minimum separation distance?
A. 15 feet, provided a fire guard is posted nearby
B. 25 feet, with appropriate shielding to prevent sparks from igniting exposed combustibles
C. 35 feet, or shielding must be provided to prevent sparks, slag or heat from igniting exposed
combustibles ✓ CORRECT
D. 50 feet, regardless of whether shielding is used
Correct Answer: C
Rationale: Under NYC Fire Code § 2604.1.1, hot work operations involving cutting or welding
shall be conducted at least 35 feet from combustible materials and combustible waste, or
shall be provided with appropriate shielding to prevent sparks, slag or heat from igniting
exposed combustibles. The 25-foot rule applies to all other hot work operations, not cutting
or welding, so answer B is a common exam trap. On the G-22 exam, always distinguish
between cutting/welding (35 feet) and other hot work (25 feet).
Question 2 of 50
A torch operator on a Manhattan rooftop is performing torch-applied roofing work using an
oxy-fuel system. During a break, the operator plans to leave the work area for approximately
,45 minutes to retrieve additional roofing membrane from the ground level. What action must
the torch operator take regarding the gas supply before leaving the work area?
A. Close only the oxygen valve and leave the fuel gas valve open for quick restart
B. Close the torch valve but leave the cylinder valves open since the break is under one hour
C. Close the torch valve and completely shut off the gas supply to the torch ✓ CORRECT
D. Leave the torch burning at a low flame to avoid relighting issues
Correct Answer: C
Rationale: Per FDNY study material and FC Chapter 26 requirements, the torch valve must be
closed and the gas supply to the torch completely shut off when hot work operations are
discontinued for a period of 1 hour or more. Even for shorter breaks, best practice and exam
standards require shutting off the gas supply entirely. Leaving cylinder valves open (answer B)
or the torch burning (answer D) creates a serious fire hazard and violates safe operating
procedures.
Question 3 of 50
During an inspection of a Queens welding shop, an FDNY inspector observes that oxygen
containers, regulators, and hoses are being handled with oily gloves that were previously
used for equipment maintenance. The shop foreman argues that the gloves are only slightly
oily and pose no real risk. What does the NYC Fire Code require regarding oxygen equipment
handling?
A. Oxygen equipment may be handled with lightly oily gloves if the oxygen pressure is below
50 psi
B. Only synthetic oil-resistant gloves are permitted when handling oxygen equipment
C. Oxygen containers, apparatus and fittings shall not be handled with oily hands, oily gloves,
or greasy tools or equipment ✓ CORRECT
D. Oily gloves are acceptable if the oxygen containers have been recently inspected
Correct Answer: C
Rationale: Under NYC Fire Code § 2604.2 and FDNY study material, oxygen containers and
oxygen container valves, regulators, hose and other apparatus and fittings shall be kept free
of oil or grease, and shall not be handled with oily hands, oily gloves, or greasy tools or
equipment. Oil and grease can cause spontaneous combustion when in contact with oxygen
under pressure. Answer A is a dangerous misconception — there is no safe pressure
threshold for oily contact with oxygen equipment.
Question 4 of 50
A contractor on a Bronx construction site needs to test a newly installed fuel gas piping
system for leaks before connecting it to the torch equipment. The site mechanic suggests
, using a lit match to check for leaks since it would provide immediate visual confirmation.
What is the proper leak-testing method required by the NYC Fire Code?
A. Use a lit match at a safe distance of at least 10 feet from the piping
B. Test for suspected leaks using soapy water or an approved leak-detector solution ✓
CORRECT
C. Use a propane torch with a low flame to slowly trace along the piping joints
D. Pressurize the system to 150% of working pressure and listen for audible leaks
Correct Answer: B
Rationale: The NYC Fire Code explicitly prohibits testing piping equipment or systems for
leaks using a flame; tests for suspected leaks shall be made using soapy water or an
approved leak-detector solution. Using a flame (answers A or C) could ignite escaping gas
and cause a fire or explosion. While pressure testing (answer D) is part of installation
procedures, it is not the approved method for routine leak detection on installed piping.
Question 5 of 50
At a commercial building renovation in Staten Island, a worker is using a blowtorch (air-fuel
torch) for brazing copper pipe fittings in a confined mechanical room. The room has limited
ventilation and no mechanical exhaust system. What is the primary safety concern the G-22
Certificate of Fitness holder must address before authorizing this work?
A. The blowtorch flame may exceed 2,000°F and damage the copper fittings
B. The accumulation of toxic fumes and potential oxygen displacement requires adequate
ventilation ✓ CORRECT
C. The confined space requires a second fire guard to be posted at the entrance only
D. The blowtorch must be converted to oxy-fuel before use in any indoor location
Correct Answer: B
Rationale: LPG and CNG are potential hazards because of their flammability and toxicity; the
chemical is in gaseous form and pressurized, and can quickly contaminate a large area in the
event of a leak. Work with torches must be done in well-ventilated areas only, and LPG/CNG
containers must not be used in a cellar, basement, pit or other area below grade without
approved ventilation. Answer C understates the ventilation requirement, and answer D is
incorrect — blowtorches are permitted indoors with proper ventilation.
Question 6 of 50
A torch operator at a Brooklyn shipyard is setting up an oxy-fuel cutting station. The operator
connects the oxygen regulator to the oxygen cylinder and then connects the acetylene
regulator to the acetylene cylinder. Before opening the cylinder valves, the operator notices
that the oxygen regulator has a small amount of grease on the threads. What is the correct
course of action?
