1. What is the primary mission of an industrial fire brigade?
A. Conduct routine security patrols
B. Protect life, control fires, and minimize property and process losses
C. Perform maintenance on production equipment
D. Replace the municipal fire department
Answer: Protect life, control fires, and minimize property and process losses
Rationale: An industrial fire brigade is organized primarily to provide immediate
emergency response, protect personnel, control incidents, and limit damage
until the hazard is stabilized or outside assistance arrives.
2. Which component of the fire triangle is removed when a fire is cooled with
water?
A. Oxygen
B. Fuel
C. Heat
D. Chemical chain reaction
Answer: Heat
,Rationale: Water primarily extinguishes many ordinary fires by absorbing heat
and reducing the fuel below its ignition temperature.
3. Which fire classification includes ordinary combustible materials such as
wood, paper, and cloth?
A. Class B
B. Class A
C. Class C
D. Class D
Answer: Class A
Rationale: Class A fires involve ordinary combustible materials that commonly
leave an ash or ember residue after burning.
4. Which extinguishing agent is generally appropriate for a flammable-liquid
fire?
A. Water stream applied directly to the liquid
B. Appropriate foam, dry chemical, or other listed Class B agent
C. Paper blankets
D. Compressed air
Answer: Appropriate foam, dry chemical, or other listed Class B agent
Rationale: Flammable-liquid fires require agents designed to interrupt
combustion or separate the fuel from oxygen while avoiding dangerous fuel
dispersion.
5. What is the primary hazard of entering a confined space during a fire
without atmospheric testing?
A. Poor visibility only
B. Unknown oxygen concentration and toxic or flammable atmospheres
C. Excessive noise
D. Wet clothing
,Answer: Unknown oxygen concentration and toxic or flammable atmospheres
Rationale: Confined spaces can contain oxygen-deficient, oxygen-enriched, toxic,
or explosive atmospheres that may not be detectable by human senses.
6. What does SCBA stand for?
A. Standard Chemical Breathing Apparatus
B. Self-Contained Breathing Apparatus
C. Supplied Chemical Breathing Assembly
D. Safety-Control Breathing Apparatus
Answer: Self-Contained Breathing Apparatus
Rationale: SCBA provides the firefighter with an independent breathing-air
supply and is commonly used in atmospheres that are immediately dangerous or
potentially hazardous to life and health.
7. Why should firefighters work in teams when operating in hazardous
industrial environments?
A. To reduce paperwork
B. To provide accountability, assistance, and emergency rescue capability
C. To increase equipment consumption
D. To eliminate the need for communication
Answer: To provide accountability, assistance, and emergency rescue capability
Rationale: The buddy or team system improves firefighter safety by ensuring
personnel can monitor one another and summon assistance when conditions
deteriorate.
8. What is flashover?
A. A small electrical spark
B. The near-simultaneous ignition of combustible materials in an enclosed area
due to rapidly increasing heat
, C. A fuel spill
D. A ventilation technique
Answer: The near-simultaneous ignition of combustible materials in an enclosed
area due to rapidly increasing heat
Rationale: Flashover occurs when heat accumulation causes exposed
combustible materials and gases in a compartment to ignite rapidly, producing
a major change in fire conditions.
9. What is backdraft?
A. A normal ventilation procedure
B. A potentially explosive ignition caused by introducing oxygen into a
ventilation-limited fire environment containing heated combustible gases
C. A hose-line pressure loss
D. A sprinkler activation
Answer: A potentially explosive ignition caused by introducing oxygen into a
ventilation-limited fire environment containing heated combustible gases
Rationale: A ventilation-limited compartment can accumulate unburned
combustible gases. Sudden introduction of oxygen can result in rapid ignition
and dangerous fire development.
10.What is the safest initial action when an industrial chemical spill is
discovered?
A. Immediately walk through the spill
B. Smell the substance to identify it
C. Isolate the area and identify the hazard from a safe location
D. Spray the substance with water
Answer: Isolate the area and identify the hazard from a safe location
Rationale: Firefighters should avoid unnecessary exposure, establish isolation,
and obtain reliable hazard information before selecting protective and control
measures.
