Q

________ ________ cars are raised and lowered by rolling steel ropes over a deeply grooved pulley, commonly called a sheave. A counterweight balances the weight of the car. The counterweight makes the elevator more efficient by offsetting the weight of the car and occupants, thereby reducing the weight the motor must move.

Q

Traction elevator machine rooms are usually located ________ _____ the hoistway of the elevator they serve.

A

directly above

19
Q

These belt-driven elevators utilize a gearless drive to move the elevator within the hoistway.
Some installations provide little or no access to the hoisting mechanisms due to their location
within the hoistway. Elevator control rooms can be installed anywhere in a building and do not typically utilize
locations common to older style elevators.

A

Machine-roomless (MRL) elevators

20
Q

A ________ is an enclosed vertical area through which an elevator car travels to reach multiple
building levels

A

hoistway

21
Q

The bottom of a hoistway is known as the pit. No personnel should enter the pit unless ?

A

power to
all elevators in the hoistway has been disconnected

22
Q

If an elevator stalls in a hoistway blind and cannot be lowered, departments should request a ?

A

technical rescue response

23
Q

________ ______ _______ is an elevator operating mode that overrides normal service and
automatically moves elevator cars to predetermined floors, allowing any passengers to exit

A

Emergency recall service (ERS)

24
Q

When _____ _ is activated, elevator cars return to the lobby level or a terminal floor. If the alarm
is activated from one of these locations, the car will go to a predetermined alternate landing with
a means of egress. Elevator cars traveling away from the lobby level when _____ _ is activated
will reverse direction at the next landing without opening their doors.

A

Phase 1

25
Q

An elevator car’s interior ERS switch has
three positions:

A

 “off” is the normal nonemergency operation;
 “on” allows the car to operate in Phase 2 ERS, and
 “hold” keeps the elevator car at a landing with the doors opened

26
Q

If an elevator car’s ____ ______ ____ __ ________the car has received a smoke detector activation
from the elevator machine room, hoistway, or pit. Personnel should not use elevators in that
hoistway.

A

fire helmet icon is flashing,

27
Q

Prior to utilizing the elevator for fires on upper floors, crews must ______ ___ _________ _______(e.g., door-open, door-close, floor selection, cancel) to ensure the elevator is operating correctly.

A

engage all elevator functions

28
Q

When the “call cancel” button is engaged, the
elevator car stops at the ?

A

next available floor landing.

29
Q

Code requirements for high-rise buildings more than ___ __ high include the installation of fire
service access elevators (FSAE). These elevators facilitate the rapid deployment of firefighters to
upper floors to reduce the reflex time required for personnel to reach those areas and begin fire
suppression operations.

A

120 ft

30
Q

Upon arrival, officers should size up the incident by?

A

 obtaining elevator keys if available,
 identifying the type of elevator involved,
 locating the position of the car relative to the hoistway opening,
 establishing communication with the elevator passengers,
 determining passengers’ number and health status, and
 requesting additional resources based on size-up and department standard operating
procedures.

31
Q

LOTO

A

lockout/tagout

32
Q

When the officer has confirmed the car is motionless, has exhausted all previously described attempts to remove the occupants with the power on, and has determined a rescue should be performed, they must adhere to the following sequence of actions to ensure the occupants’ safe
removal:

A

 Attempt to perform a hard reset of the system. This involves removing power via the
mainline disconnect and waiting 30–60 s and then turning power back on to the system.

 Shut down and secure power to the stalled elevator.
 Access the hoistway.
 Access the stalled car.
 Assist occupants out of the stalled car.
 Secure the scene to prevent further use of the problematic elevator.

33
Q

To ensure this power stays off, personnel must
padlock the switch to lock out the mainline disconnect breaker. This procedure is commonly referred to as LOTO. If no padlock is available, a member with a radio should?

A

remain
at the panel until the rescue has been completed

34
Q

Q

When an elevator car platform is more than _ __ _____ ___ ______ , it is inadvisable to remove
passengers from the car

A

3 ft above the landing

37
Q

If a stalled elevator car platform is positioned within 3 ft above or below the landing level, personnel should take the following actions:

A

 Confirm mainline disconnect LOTO procedures have been completed.
 Block any hoistway opening beneath the car with a ladder or similar object if a gap
exists.

 A set of forcible entry tools is available for use.
 Phase 2 ERS is activated.
 The elevator is not overloaded.

40
Q

Personnel should use an ERS key to manipulate the ERS switch to an “on” position and then
press the door-close button. Personnel should then select a floor that is ___ __ ___ _____ _____ _____ _______ _______. The car should stop at the selected floor. If the car fails to do so, personnel
should press the?
