repeatedly and practice calculations for success.
Section 1: Safety and Basic Concepts (Questions 1–50)
Question 1: What piece of safety equipment is designed to keep you from falling?
Answer: Safety harness and lanyard.
Explanation: A safety harness, connected to a secure anchor via a lanyard,
prevents falls from heights like hoistways or car tops. Inspect before use to
ensure no wear or damage. Required by OSHA for high-risk tasks. Always
clip to a structural anchor point.
Question 2: What must be done before checking pump drive belts on a hydraulic elevator?
Answer: Pull the main LOTO disconnect switch.
Explanation: Lockout/Tagout (LOTO) cuts power to the system, preventing
accidental startup during belt inspection. This ensures mechanic safety from
electrical or mechanical hazards. Verify lockout with a voltmeter before
proceeding.
Question 3: Why must you pull the main disconnect LOTO switch before checking the
oil reservoir?
Answer: To prevent electrical hazards during inspection.
Explanation: The LOTO switch isolates power, eliminating risks of shock
or pump activation while checking the oil level. This is a standard OSHA
1
, procedure. Always tag the switch to warn others.
Question 4: What are the main hazards in the machine room of a geared traction eleva-
tor?
Answer: Electrical and mechanical hazards.
Explanation: High-voltage wiring poses shock risks, while moving parts like
gears and motors can cause entanglement or crushing injuries. Proper PPE
and LOTO are critical. Heat from equipment adds burn risks.
Question 5: How do you determine the correct angle from the vertical placing of the
ladder?
Answer: 1/4 the height.
Explanation: For stability, the ladder base should be one-quarter its height
from the wall (approximately 75 degrees). This prevents tipping or sliding
during use. Use a level to confirm setup.
Question 6: Which term describes a body harness used with a shock-absorbing lanyard?
Answer: Personal fall arrest system.
Explanation: This system includes a harness, lanyard, and anchor to stop
falls safely. Required for work above 6 feet in hoistways. Inspect for wear
before each use.
Question 7: A mechanic finds a carpenter using a powder-activated tool to anchor wall
track. What should the mechanic do?
Answer: Notify the supervisor immediately.
Explanation: Powder tools can propel debris, posing risks to untrained per-
sonnel nearby. Only certified workers should operate them. Reporting en-
sures site safety compliance.
Question 8: Who is responsible for ensuring adequate lighting at a work site?
Answer: You (the individual worker).
Explanation: Mechanics must ensure sufficient lighting to avoid errors or
trips. Portable lights may be needed in dim areas like pits. OSHA requires
10 foot-candles minimum.
Question 9: What are the two most common causes of public accidents on elevators?
Answer: Trips and falls, and being struck by doors.
Explanation: Uneven leveling causes trips, and fast-closing doors can strike
passengers. Regular maintenance of leveling sensors and door operators pre-
vents these issues.
Question 10: Before shortening a governor rope, what safety steps should be taken?
Answer: LOTO and support tension sheave.
Explanation: Lockout power to prevent movement, and support the sheave
to avoid rope snap or injury. Use a come-along to hold tension during ad-
justment.
Question 11: Unsure if a hoistway is a permit-required confined space. What should you
do?
2
, Answer: Do not enter until evaluated by a qualified person.
Explanation: Confined spaces may have low oxygen or toxins. A qualified
person tests air and ensures rescue plans. OSHA mandates permits for such
spaces.
Question 12: After LOTO on the electrical system, what safety step is needed before
entering an escalator truss?
Answer: Install a mechanical lock.
Explanation: A mechanical lock prevents accidental startup, complementing
electrical LOTO. This ensures safety during truss work. Check lock integrity
before entry.
Question 13: Before lubricating a governor tension sheave in a traction elevator pit, what
must be done?
Answer: LOTO the main power.
Explanation: Locking out power prevents unexpected car movement, pro-
tecting workers in the pit. Tag the switch and verify with a voltmeter. PPE
is also required.
Question 14: When pit depth exceeds what measurement does ASME A17.1 require a pit
ladder?
Answer: 35 inches.
Explanation: Deeper pits increase fall risks; ladders ensure safe access.
ASME A17.1 mandates this for maintenance and emergency access. Check
ladder condition.
Question 15: In which conveyance system is energy applied by liquid under pressure?
Answer: Hydraulic elevator.
Explanation: Hydraulic elevators use pressurized oil to lift the car, ideal for
low-rise buildings. Pascal’s Law governs operation. Common in buildings
up to 6 stories.
Question 16: Which entity requires training on chemical health effects?
Answer: OSHA.
Explanation: OSHA’s Hazard Communication Standard mandates training
on chemicals like hydraulic oil or lubricants. Includes short- and long-term
health risks.
Question 17: When must barriers be installed around an escalator during maintenance?
Answer: Whenever the public is present.
Explanation: Barriers prevent public access to moving parts, reducing injury
risks. Use cones or tape with clear signage. Required by ASME A17.1.
Question 18: What safety device might you encounter in a hydraulic elevator pit?
Answer: Plunger gripper.
Explanation: Grippers clamp the plunger if pressure drops, preventing the
car from falling. Inspect during maintenance to ensure functionality.
Question 19: A crew finds the machine room floor being poured. What precautions are
