Question 1
Which tool is most appropriate for cutting a galvanized iron pipe?
A) Wood saw
B) Hacksaw
C) Jigsaw
D) Coping saw
Correct Answer: B) Hacksaw
Rationale: A hacksaw is designed with fine teeth suitable for cutting metal pipes,
including galvanized iron. Wood saws and jigsaws are for wood, and coping saws
are for intricate curves in thin materials.
Question 2
What is the primary purpose of a GFCI (Ground Fault Circuit Interrupter)?
A) Prevent circuit overloads
B) Protect against electrical shock
C) Reduce energy consumption
D) Increase voltage stability
Correct Answer: B) Protect against electrical shock
,Rationale: GFCIs monitor current imbalance between hot and neutral wires; if a
ground fault occurs, they quickly shut off power to prevent electrocution,
especially in wet areas.
Question 3
A leaking faucet dripping once per second wastes approximately how many
gallons per year?
A) 500
B) 1,000
C) 3,000
D) 8,000
Correct Answer: C) 3,000
Rationale: One drip per second equals about 5 gallons per day, or 1,825 gallons per
year. However, industry standards round up to roughly 3,000 gallons due to
variable drip sizes and pressure.
Question 4
When using a ladder, the base should be placed how far from the wall for every 4
feet of height?
A) 6 inches
B) 12 inches
C) 18 inches
D) 24 inches
Correct Answer: B) 12 inches
*Rationale: The 4-to-1 rule: for every 4 feet of ladder height, the base should be 1
foot away from the wall to maintain stability and reduce slipping risk.*
,Question 5
What type of fire extinguisher is used for electrical fires?
A) Class A
B) Class B
C) Class C
D) Class D
Correct Answer: C) Class C
*Rationale: Class C extinguishers contain non-conductive agents (e.g., CO2 or dry
chemical) suitable for energized electrical equipment.*
Question 6
Which plumbing fixture typically has a trap to prevent sewer gases from entering a
building?
A) Toilet
B) Sink
C) Floor drain
D) All of the above
Correct Answer: D) All of the above
Rationale: Every plumbing fixture that connects to the drainage system must have
a trap (either integral or external) to block sewer gases.
Question 7
A circuit breaker that trips repeatedly most likely indicates:
, A) Too many appliances on the circuit
B) A short circuit
C) A faulty breaker
D) All of the above
Correct Answer: D) All of the above
Rationale: Overloads, short circuits, ground faults, or a defective breaker can cause
repeated tripping; all are possible and require investigation.
Question 8
What is the minimum clearance required in front of an electrical panel according to
NYC code?
A) 18 inches
B) 24 inches
C) 30 inches
D) 36 inches
Correct Answer: C) 30 inches
Rationale: NYC Electrical Code (based on NEC) requires 30 inches width and 36
inches depth clearance in front of panels for safe access.
Question 9
When soldering copper pipe, which flux is appropriate for potable water systems?
A) Acid-based flux
B) Water-soluble flux
C) Petroleum-based flux
