QUESTION 1
A maintenance worker is tasked with replacing a section of galvanized
steel pipe that has corroded. Which of the following tools is most
appropriate for cutting the pipe in a confined space where electrical
sparks pose a hazard?
A) Reciprocating saw with a bi-metal blade
B) Angle grinder with a cut-off wheel
C) Hacksaw with a fine-tooth blade
D) Oxy-acetylene torch
ANSWER: C
Explanation: In a confined space with potential flammable or explosive
atmospheres, spark-producing tools such as reciprocating saws, angle
grinders, and oxy-acetylene torches should be avoided. A manual
hacksaw with a fine-tooth blade generates no sparks and provides

controlled cutting action, making it the safest option under these
conditions. Additionally, the fine tooth count is suited for cutting metal
pipe with minimal burr formation.
QUESTION 2
Which of the following sequences represents the correct order of
operations when responding to a report of a gas odor in a NYCHA
residential building?
A) Ventilate the area, locate the source, evacuate residents, call the gas
company
B) Evacuate residents, call the gas company, ventilate the area, locate
the source if safe
C) Call the gas company, evacuate residents, locate the source,
ventilate
D) Locate the source, evacuate residents, call the gas company,
ventilate
ANSWER: B
Explanation: Safety protocol for gas odor mandates immediate
evacuation of all occupants from the affected area to prevent inhalation
or explosion risk. The gas company must be notified promptly so that
they can shut off supply and test for leaks. Ventilation and source
location follow only after the area is cleared and utility professionals are
on site, as unauthorized personnel should not attempt to locate or
repair gas leaks.

QUESTION 3
A boiler pressure gauge reads 15 psi, but the temperature gauge shows
220°F. Given that water boils at 212°F at atmospheric pressure, what is
the most likely interpretation?
A) The boiler is operating under vacuum
B) The temperature sensor is faulty
C) The system is operating as expected under elevated pressure
D) The pressure relief valve is stuck open
ANSWER: C
Explanation: The boiling point of water increases as pressure increases.
At 15 psi gauge pressure (approximately 30 psia), the saturation
temperature is roughly 250°F, so 220°F is below boiling and indicates
normal liquid water operation. The readings are consistent with a
pressurized hot water heating system. A faulty sensor or stuck valve
would produce more erratic discrepancies between pressure and
temperature.
QUESTION 4
When performing preventive maintenance on a rooftop HVAC air
handling unit, which of the following should be checked first to ensure
electrical safety?
A) Refrigerant charge level
B) Condition of fan belts
C) Disconnect switch is in the "OFF" position and locked out
, 4|Page
D) Drain pan for standing water
ANSWER: C
Explanation: Lockout/tagout procedures are the foremost safety step
before any maintenance on electrically powered equipment. Verifying
that the disconnect switch is off and locked prevents accidental
energization while the worker is inside the unit. Only after electrical
isolation should mechanical components such as belts, refrigerant, or
drain pans be inspected.
QUESTION 5
A resident reports a slow-draining bathtub. The maintenance worker
uses a plunger but the water does not drain. What is the next most
appropriate step?
A) Pour a chemical drain cleaner down the overflow
B) Remove the drain stopper and inspect for hair and debris
C) Snake the drain from the cleanout access point
D) Replace the entire trap assembly
ANSWER: B
Explanation: The most common cause of slow tub drainage is
accumulated hair and soap scum directly at the drain stopper
mechanism. After plunging fails, the least invasive and most logical next
step is to remove the stopper and manually clear visible debris.
Chemical cleaners may damage older pipes and are not recommended
