Question 1: What is the first thing a maintenance worker should do before starting any repair job?
A) Gather all necessary tools
B) Notify the supervisor
C) Assess the work area for safety hazards
D) Begin the repair immediately
Correct Answer: C Assess the work area for safety hazards
Rationale: Before beginning any repair work, assessing the area for safety hazards is critical to
prevent accidents and injuries. This includes checking for electrical hazards, structural instability,
chemical exposures, and ensuring proper ventilation. Safety always comes first in maintenance
operations .
,Question 2: Which personal protective equipment (PPE) is most important when working with
electrical circuits?
A) Steel-toed boots
B) Rubber-insulated gloves
C) Hard hat
D) Safety goggles
Correct Answer: B Rubber-insulated gloves
Rationale: Rubber-insulated gloves provide protection against electrical shock when working
with live circuits. They are specifically designed and rated for electrical work. While other PPE
may be necessary depending on the task, electrical protection is paramount when working with
circuits .
Question 3: What does the term "lockout/tagout" refer to?
A) Securing tools in a locked toolbox
B) Locking doors to prevent unauthorized access
C) De-energizing equipment and locking it to prevent accidental startup
D) Locking chemical storage cabinets
Correct Answer: C De-energizing equipment and locking it to prevent accidental startup

shut off and cannot be started again before maintenance or repair work is completed. It involves
placing a lock and tag on the energy-isolating device to prevent accidental energization .
, Question 4: When using a ladder, what is the proper angle for placement?
A) 45 degrees
B) 60 degrees
C) 75 degrees
D) 90 degrees
Correct Answer: C 75 degrees
Rationale: A ladder should be placed at approximately a 75-degree angle, which translates to the
base being 1 foot away from the wall for every 4 feet of ladder height. This angle provides optimal
stability and prevents the ladder from tipping backward or slipping out at the base .
Question 5: What should you do if you discover a gas leak in a NYCHA apartment?
A) Try to find and fix the leak
B) Open windows, evacuate residents, and report immediately
C) Turn on exhaust fans

Rationale: Gas leaks are life-threatening emergencies. The correct response is to ventilate the
area by opening windows, evacuate all occupants, and report the leak immediately to supervisors
and the gas company. Never attempt to locate or repair a gas leak yourself, and avoid creating
any sparks or using electrical devices .
