SAF Fire Safety & Prevention 2 — Questions and Answers
Question 1: A fire involving flammable liquids such as gasoline, oil, and paint is classified as which class?
- Class A
- Class B (Correct answer)
- Class C
- Class K
Correct answer: Class B
Class B fires involve flammable and combustible liquids including gasoline, oil, grease, and solvents.
Question 2: When using the PASS technique with a fire extinguisher, what does the first 'P' instruct the user to do?
- Point the nozzle at the base of the fire
- Pull the safety pin (Correct answer)
- Position yourself upwind of the fire
- Press the discharge handle fully
Correct answer: Pull the safety pin
PASS stands for Pull, Aim, Squeeze, Sweep — pulling the safety pin is the first step to unlock the extinguisher for use.
Question 3: Per OSHA 29 CFR 1910.36, what is the minimum number of means of egress generally required for most workplaces?
- One
- Two (Correct answer)
- Three
- Four
Correct answer: Two
OSHA 29 CFR 1910.36 requires at least two means of egress so employees can escape if one exit path is blocked by fire or smoke.
Question 4: Which organization publishes the National Fire Codes, including NFPA 70 (National Electrical Code) and NFPA 101 (Life Safety Code)?
- OSHA
- EPA
- National Fire Protection Association (NFPA) (Correct answer)
- American National Standards Institute (ANSI)
Correct answer: National Fire Protection Association (NFPA)
The National Fire Protection Association (NFPA) publishes the National Fire Codes, a comprehensive series of fire safety standards and codes.
Question 5: According to NFPA 10, what is the maximum travel distance to a portable fire extinguisher for Class B hazards (excluding cooking media)?
- 30 feet (9 m)
- 50 feet (15 m) (Correct answer)
- 75 feet (23 m)
- 100 feet (30 m)
Correct answer: 50 feet (15 m)
NFPA 10 limits travel distance to a Class B fire extinguisher to 50 feet (15 m) to ensure rapid access during a fast-spreading liquid fire.
Question 6: What is the primary purpose of a hot work permit system in the workplace?
- To authorize contractors to work overtime in high-temperature environments
- To control ignition sources during welding, cutting, or other spark-producing operations (Correct answer)
- To track maintenance schedules for furnaces and industrial boilers
- To document employee heat-stress training completion records
Correct answer: To control ignition sources during welding, cutting, or other spark-producing operations
Hot work permits ensure adequate fire precautions are established before and during spark- or flame-producing operations near combustible materials.
Question 7: Which type of fire detector responds to invisible combustion particles before smoke becomes visible to the naked eye?
- Photoelectric smoke detector
- Ionization smoke detector (Correct answer)
- Fixed-temperature heat detector
- UV flame detector
Correct answer: Ionization smoke detector
Ionization detectors use a small radioactive source to detect invisible combustion ions produced during the early fast-flaming stage of a fire.
