NEWEST 2026 TEST BANK| COMPLETE 350 REAL EXAM
QUESTIONS AND CORRECT VERIFIED ANSWERS/
ALREADY GRADED A+ (MOST RECENT!!)
Q1. Which class of fire involves energized electrical
equipment?
A) Class A
B) Class B
C) Class C
D) Class D
Correct Answer: C
Rationale: Class C fires involve energized electrical equipment.
Use non-conductive extinguishing agents (CO₂, dry chemical).
Water conducts electricity.
Q2. What does a lockout/tagout (LOTO) procedure ensure?
A) Equipment runs faster during maintenance
,B) Equipment is de-energized and cannot be re-energized
accidentally
C) Equipment is cleaned after shutdown
D) Equipment is lubricated before start-up
Correct Answer: B
Rationale: LOTO isolates energy sources and prevents
accidental start-up during maintenance or repair. OSHA 29 CFR
1910.147.
Q3. Which of the following is the unit of electrical resistance?
A) Volt
B) Ampere
C) Ohm
D) Watt
Correct Answer: C
Rationale: Ohm (Ω) measures resistance. Volt measures
voltage, ampere measures current, watt measures power.
