Emergencies 1-Elevator Op's Flashcards
What determines an elevator emergency?
FIP
2.4.2
A situation where one or more of the following exist:
A. Fire endangering passengers in a stuck elevator.
B. Passenger of stuck elevator injured.
C. Passenger of stuck elevator in panic.
What is the most frequent cause of elevator malfunctions?
3.1.1
Electrical problems are the most frequent cause of elevator malfunction.
What are the 6 ways to locate the stalled elevator car?
3.2.1
A. Lobby control panel - check floor indicator.
B. If available use intercom or telephone system of the stuck car. Passengers may be able to give their approximate location.
C. Open the hoistway door at first floor with elevator key and look up shaft. Key devices are usually required at the lower levels and may be present at all levels.
1. If the hoistway door has a glass panel check the shaft before opening the door. Using a flash light, look for the governor ropes and the
counterweight. Movement of either one of these is an indication that the car is in motion, do not open the hoistway door. The governor rope is
generally located on either side near one of the far corners of the shaft.
D. The location of the counterweight can be used to approximate the position of the car. For example, in a 6 story building where the elevator serves the basement, if the counterweight is on the 1st floor, the stalled car would be at the 5th. The counterweight can be located by viewing through the wire glass door panel or by opening a hoistway door.
E. Enter a car in the same bank and open top hatch if no damage will be done to the elevator car.
F. Use the floor selector in the machinery room, it indicates the exact location of elevator car.
There are two types of primary removal procedures. The order in which they are tried is
not important. What are they?
- 3.1 & 3.3.2
- Checking Electrical Contacts.
- The second type of primary removal procedure is activating Firemen Service if available. Firemen Service WILL over ride the Emergency Stop Button.
Summon an elevator mechanic if Primary Removal Procedures fail. Telephone number of the mechanic is required to be posted in the machinery
room near the elevator power switch. Consider the possibility of an elevator mechanic on duty in a nearby building. We shall wait for the Elevator mechanic before trying secondary removal procedures.
True or False
3.4.3
False
Secondary Removal Procedures may be initiated prior to the arrival of the mechanic.
What is essential whenever Secondary or Emergency Removal procedures are used?
3.5.1
Whenever Secondary or Emergency Removal Procedures are used, power removal is essential.
Dispatch ___ members to the elevator machinery room to shut off the power to the stalled car. The machinery room may be located at the top of the shaft, at the bottom of the shaft or ___ levels above the highest floor serviced by the elevator.

False
They should be taken up and out of the car if practical.
The elevator car shall NEVER be jacked or moved in what direction?
3.5.2 E

Elevators with 2 speed systems are commonly found in Bldg’s over how many stories?
3.6.3
Commonly found in buildings over 10 stories
If the elevator has a two speed system, commonly found in buildings over 10 stories, what procedure may work?
If the car is to restart how long will it take?
3.6.3
A. If Emergency Stop Button has been activated have passengers deactivate it.
B. Have members in elevator machinery room shut power to the stuck car and turn it on again.

shut off and members are not to restore power after completion of operations.
C. If the car is to restart it will do so within 10 seconds.
D. Communications must be maintained when attempting this procedure. Passengers and members must be prepared for the sudden movement of the car or car door.
Member in the adjacent car inserts pole or hook between the striking post and the hoistway door and trips the lock by either depressing the roller or
pushing on the locking arm.
Which door type do we depess the roller?
3.6 D
Hinge type door - Depress the roller.
Sliding type door - push up on locking arm.
When doing a top hatch removal how many members are to be permitted on the roof of the elevator at one time?
3.7 A
Climb down to the car roof. Maximum of two firefighters are to be permitted on the roof of the car at one time.
Who determines the order of removal when using the top hatch of the elevator?
3.7 A
One member equipped with a handie talkie enters car. Member in the car must determine the order of removal. Secure each person with a life saving rope.
When doing a side exit removal what must be done to the rescue car after it is brought even to the stuck elevator car?
3.7 B
Remove power to rescue car. Power to the stuck car was previously removed.
What is required to open the side exit of the rescue car?
3.7 B
A key or forcible entry is required to open panel from inside the car.
What is required to open the side exit of the stuck car?
3.7 B
Open side exit of stuck car. It is openable by hand from the shaft side.
What size planks should be used to bridge between the cars in a side exit removal?
3.7 B
Planks of sufficient lengths (6’ or longer) should be used as a bridge between cars.
When using forcible entry on a hinged elevator door wher will we find the roller?
3.7.3 A
Push down roller, located near side opposite hinges, on shaft wall.
What is the preferred forcible entry method of a sliding type elevator door?
3.7.3 B
The Maxi Force air bag system. It is less likely than the others to push the door off its hangers or out of its track.
Where do we place the air bag when using on a elevator door?
3.7.3 B
Place bag between the leading edge of the door and jamb as high as possible to apply a more direct force on the linkage and the locking mechanism.
Also when using the Rabbit Tool to force entry.
The Elevator Pit is the lowest portion of the elevator shaft. What are the 2 types?
4.1.1 A & B
Jump Pits and Walk in Pits
The Jump pit is usually __ to __ from lowest landing level to base of pit.
Fill in the blanks
How is the Pit entered?

4 ft.-6 ft.
Pit is entered by opening the lowest hoistway door and using a portable ladder.
Elevator descends to within a couple of feet of the bottom of the shaft.
The walk in Pit is usually __ to __ from lowest landing to base of pit.
Fill in the blanks
How is the pit entered?
4.1.1 B
6 ft.-10 ft.
Access to the pit is via a door located at the bottom of the shaft. Door is not required to have an interlock switch. Door is opened by a regular key. Emergency elevator keys are not usable

.
.
What prevents the car from entering a walk in pit?
4.1.1 B
A high buffer and lower limit switch prevent the car from entering the pit.
If there is a fire in the pit, why do we need to be cautious of the buffers (a device designed to stop a descending elevator beyond the normal limits of travel)?
4.2.2 B
They may be filled with combustible or inflammable liquid.
Can we enter a walk in pit prior to power being shut off?
4.2.2 D.
In an EXTREME EMERGENCY (immediate action necessary to save life) entry to a Walk in Pit before the elevator power switch is off may be made using the following precautions:
1. Open a hoistway door on shaft to be entered. The interlock will prevent car from moving.
2. Use caution around mechanical and electrical components.
3. Turn off power as soon as possible.
Members of the EMS Command have been issued FDNY 1620 keys for use of the Fire Service feature in elevators. Members arriving at incidents and discovering Fire Service elevators in use shall contact the EMS unit on the Fire/EMS
Interoperability (IO) frequency to coordinate elevator operations.
What HT channel is used?
5 Note:
Channel 10
