,Core Competency Domains:
Fire Classification and Extinguishing Principles
Selection and Application of Portable Fire Extinguishers
Inspection, Maintenance, and Testing Requirements
Installation and Placement Standards
Safety Practices and Regulatory Compliance
Operational Readiness and Hazard Assessment
This assessment evaluates a candidate’s technical understanding of portable fire
extinguishers in accordance with nationally recognized fire protection standards. It
focuses on hazard identification, correct extinguisher selection, maintenance procedures,
and compliance with applicable codes. Candidates are expected to demonstrate applied
knowledge in real-world scenarios involving fire risks in industrial, commercial, and
residential environments. Mastery of extinguisher classifications, ratings, and inspection
protocols is essential for safe and effective fire response.
Candidates must complete all 60 multiple-choice questions within 90 minutes. Each
question has one correct answer. Read each scenario carefully before selecting the best
response. Marks are awarded for accuracy only; no penalty for incorrect answers. Ensure
,all responses are clearly marked. Calculators are not required. Compliance with safety
standards and practical reasoning will be heavily emphasized throughout the exam.
Q1. A technician is selecting an extinguisher for a facility storing energized electrical
panels and sensitive electronic equipment. Which extinguisher type is MOST appropriate
to prevent damage and ensure safety?
A. Water extinguisher
B. Dry chemical ABC extinguisher
C. Carbon dioxide (CO₂) extinguisher
D. Class K wet chemical extinguisher
Correct Answer: 🔴 C. Carbon dioxide (CO₂) extinguisher
Explanation: 🟡 CO₂ extinguishers are ideal for energized electrical equipment because they
are non-conductive and leave no residue, preventing damage to sensitive electronics. Water
(A) is conductive and dangerous. ABC dry chemical (B) is effective but leaves residue harmful
to electronics. Class K (D) is designed for cooking oils, not electrical fires.
Q2. During inspection, an extinguisher gauge indicates pressure below the operable range.
According to NFPA 10, what is the correct action?
A. Shake the extinguisher and recheck
, B. Recharge or replace the extinguisher
C. Adjust the gauge manually
D. Continue use until empty
Correct Answer: 🔴 B. Recharge or replace the extinguisher
Explanation: 🟡 NFPA 10 requires extinguishers outside the operable pressure range to be
removed from service and recharged or replaced. Shaking (A) does not fix pressure issues.
Gauges cannot be manually adjusted (C). Continuing use (D) is unsafe and non-compliant.
Q3. A facility requires extinguishers for Class D combustible metals. Which characteristic is
essential for these extinguishers?
A. High-pressure discharge
B. Specialized dry powder agents
C. Water-based cooling capability
D. Foam blanket formation
Correct Answer: 🔴 B. Specialized dry powder agents
Explanation: 🟡 Class D fires involve combustible metals requiring specific dry powder
agents that smother and absorb heat. High pressure (A) is not the key factor. Water (C) reacts
dangerously with metals. Foam (D) is ineffective.
