Introduction
The purpose of this assessment is to evaluate the technical proficiency and safety knowledge of candidates seeking certification for torch
operations. The exam assesses critical skills including equipment inspection, safe handling of flammable gases, regulatory adherence, and
emergency decision-making. Through a structured format of multiple-choice and scenario-based questions, candidates must demonstrate an
understanding of real-world fire prevention and mitigation strategies. This exam emphasizes the application of fire codes and safety protocols
essential for maintaining workplace security. Success requires a mastery of both foundational theory and the practical ability to execute safe
torch operations under varying environmental conditions.
SECTION ONE: QUESTIONS 1–100
What is the primary safety requirement when storing fuel gas cylinders?
A. Cylinders must be stored horizontally at all times.
B. Cylinders must be stored at least 20 feet from oxygen cylinders.
C. Cylinders must be secured in an upright position.
D. Cylinders must be stored in direct sunlight to maintain pressure.
🟢C
🔴 RATIONALE: To prevent the safety relief valve from being blocked and to ensure proper gas flow, all cylinders must be secured in
an upright position.
,Which fire extinguisher class is most appropriate for a fire involving flammable liquids during torch operations?
A. Class A
B. Class B
C. Class C
D. Class D
🟢B
🔴 RATIONALE: Class B extinguishers are specifically rated for fires involving flammable liquids, such as the fuels used in torches.
Before beginning torch operations, what is the mandatory first step regarding the work area?
A. Inspecting the torch tip for damage.
B. Clearing the area of all combustible materials.
C. Turning on the oxygen supply.
D. Checking the wind direction.
🟢B
🔴 RATIONALE: Removing combustibles is the most effective fire prevention step, as it eliminates the fuel source for a potential fire.
How often must torch operation equipment be inspected?
A. Weekly
B. Monthly
C. Before each use
D. Annually
🟢C
🔴 RATIONALE: Equipment must be inspected before every use to ensure there are no leaks, cracks, or malfunctions that could cause
an accident.
In the event of a flashback, what is the correct immediate action?
A. Close the oxygen valve first.
B. Close the fuel gas valve first.
C. Continue working to clear the flame.
D. Submerge the torch in water immediately.
🟢B
🔴 RATIONALE: Closing the fuel gas valve immediately cuts off the fuel source, which is the necessary step to extinguish a flashback.
What is the maximum pressure at which acetylene gas should be used?
A. 10 psig
B. 15 psig
, C. 25 psig
D. 30 psig
🟢B
🔴 RATIONALE: Acetylene becomes chemically unstable and poses a significant explosion risk at pressures exceeding 15 psig.
Who is responsible for ensuring a Fire Watch is present when required?
A. The building owner only.
B. The Certificate of Fitness holder.
C. The local fire department.
D. The equipment manufacturer.
🟢B
🔴 RATIONALE: The person performing the work (the COF holder) has the primary responsibility to ensure all fire safety precautions,
including the Fire Watch, are in place.
Which gas is commonly used as the fuel source for torch operations?
A. Nitrogen
B. Argon
C. Acetylene
D. Helium
🟢C
🔴 RATIONALE: Acetylene is a common, high-heat fuel gas used in oxy-fuel torch operations.
What is the purpose of a flashback arrestor?
A. To increase the flame temperature.
B. To prevent the flame from traveling back into the hoses or cylinders.
C. To measure the gas pressure.
D. To regulate the fuel flow.
🟢B
🔴 RATIONALE: Flashback arrestors are safety devices designed to stop a flame front from moving backward into the gas supply
lines.
When performing torch operations, what personal protective equipment is mandatory for eye protection?
A. Standard safety glasses.
B. Sunglasses.
C. Shaded goggles or a face shield meeting ANSI Z87.1.
D. A standard medical mask.
