INTRODUCTION
This examination assesses the knowledge and skills required for fire suppression
professionals practicing in Michigan. It evaluates foundational fire science theory,
applied system knowledge, regulatory compliance, and ethical decision-making. The
exam consists entirely of multiple-choice questions, including scenario-based items
that simulate real-world field conditions. Emphasis is placed on practical application,
critical thinking, and the ability to make sound judgments under pressure. Candidates
must demonstrate competency across installation, inspection, testing, and
maintenance domains to ensure public safety and code compliance.
SECTION ONE: QUESTIONS 1–300
1. A Class B fire involves which type of fuel?
A. Combustible metals
B. Cooking oils and fats
C. Flammable liquids
,D. Ordinary combustibles
C. Flammable liquids
RATIONALE: Class B fires are fueled by flammable or combustible liquids such as
gasoline, oils, and solvents. Class D covers metals, and Class K covers cooking media.
2. The primary purpose of a pre-incident plan is to:
A. Replace the need for ongoing training
B. Provide information for safe and effective incident operations
C. Document equipment purchase histories
D. Establish personnel seniority rosters
B. Provide information for safe and effective incident operations
RATIONALE: Pre-incident plans give responders critical knowledge about building
layout, hazards, and suppression systems before an emergency occurs, enabling safer
and more efficient operations.
3. According to NFPA standards, the maximum travel distance to a fire extinguisher for
a Class A hazard shall not exceed:
A. 25 feet
B. 50 feet
C. 75 feet
D. 100 feet
C. 75 feet
RATIONALE: NFPA 10 establishes a maximum travel distance of 75 feet to a Class A
extinguisher for ordinary hazard occupancies, ensuring timely access.
4. A dry chemical fire extinguisher works primarily by:
A. Cooling the fuel below its ignition temperature
B. Removing the fuel source
C. Interrupting the chemical chain reaction
,D. Displacing all oxygen from the area
C. Interrupting the chemical chain reaction
RATIONALE: Dry chemical agents, such as sodium bicarbonate or monoammonium
phosphate, interrupt the combustion chain reaction, which is the primary extinguishing
mechanism.
5. The correct sequence of actions when using a portable extinguisher is:
A. Aim, Pull, Squeeze, Sweep
B. Pull, Aim, Sweep, Squeeze
C. Pull, Aim, Squeeze, Sweep
D. Squeeze, Pull, Aim, Sweep
C. Pull, Aim, Squeeze, Sweep
RATIONALE: The PASS acronym stands for Pull the pin, Aim at the base of the fire,
Squeeze the handle, and Sweep side to side.
6. What is the minimum required extinguisher classification within 30 feet of commercial
kitchen cooking equipment?
A. One Class A
B. One Class K
C. Two Class B
D. Two Class C
B. One Class K
RATIONALE: NFPA 10 and NFPA 96 require a Class K extinguisher for commercial
cooking hazards involving combustible cooking media such as vegetable oils and
animal fats.
7. A Class D fire involves:
A. Energized electrical equipment
B. Combustible metals
, C. Flammable gases
D. Cooking oils
B. Combustible metals
RATIONALE: Class D fires involve combustible metals such as magnesium, sodium,
titanium, and potassium, requiring specialized dry powder agents.
8. The term "flashover" refers to:
A. A type of portable extinguisher
B. The rapid transition to a fully developed fire
C. The cooling of hot gases above a flame
D. The ignition of a single fuel item
B. The rapid transition to a fully developed fire
RATIONALE: Flashover is the near-simultaneous ignition of all exposed combustible
surfaces in a compartment, marking the transition from growth to fully developed fire.
9. The fire triangle consists of fuel, heat, and:
A. Smoke
B. Oxygen
C. Pressure
D. Chemical chain reaction
B. Oxygen
RATIONALE: The fire triangle comprises fuel, heat, and oxygen. The fire tetrahedron
adds the chemical chain reaction for flaming combustion.
10. Which extinguishing agent is most effective on a Class C fire?
A. Water
B. Carbon dioxide
C. Foam
