104
Q

Elevator keys can be used to activate

A

Phase 1 ERS

105
Q

If the alarm is activated from the lobby level or a terminal floor, the car will

A

Go to a predetermined alternate landing with a means of egress

106
Q

During Phase 1, elevator cars at any landing other than the lobby level will immediately

A

Close their doors and return nonstop to the lobby

107
Q

Emergency stop buttons are rendered inoperative in

A

Phase 1

108
Q

To utilize an ERS-equipped elevator to access upper floors, personnel should

A

Leave the lobby control switch in the “on” position and remove the key

109
Q

For ERS the normal nonemergency operation switch is in the

A

“off” position

110
Q

FOR ERS this position allows the car to operate in Phase 2 ERS

A

“on” position

111
Q

For ERS this position keeps the elevator car at a landing with the doors opened

A

“hold” position

112
Q

Some older installations have a “bypass” position instead of

A

“hold” position

113
Q

If the car’s fire helmet icon is flashing, the car has received a

A

Smoke detector activation from the elevator machine room, hoistway, or pit

114
Q

Prior to utilizing the elevator for fires on upper floors, crews MUST

A

Engage all elevator functions (door-open, door-close, floor selection, cancel)

115
Q

Button that allows the operator to change floor selection or direction of travel prior to reaching the original selected floor

A

“call cancel” (reset)

116
Q

When Phase 2 ERS is activated, personnel must

A

Hold the buttons for opening and closing doors until the desired action is complete

117
Q

If a member leaves the car before the door has fully opened, the door will automatically close behind them and that will

A

Isolate the car and place it out of service

118
Q

The emergency button is rendered inoperative during

A

Phase 1

119
Q

The emergency stop button will quickly stop an elevator car while ascending or descending to a selected destination

A

Phase 2

120
Q

After reaching the required floor, the last crew member should switch the fire service key to the

A

“off” position which will place the ERS back into Phase 1 and return the elevator to the main discharge floor

121
Q

Code requirements for high-rise buildings more than 120 feet high include the installation of

A

Fire service access elevators (FSAE)

122
Q

The FSAE system will have standby power capable of running the elevator for

A

2 hours

123
Q

Incidents in which passengers are inconvenienced but not injured by their elevator entrapment should be considered

A

Nonemergency incidents

124
Q

Upon arrival of an elevator incident the officer should size up the incident by

A
  • obtaining elevator keys if available
  • identify the type of elevator involved
  • locate the position of the car relative to the hoistway opening
  • establish communication with the elevator passengers
  • determine passengers’ number and health status
  • request additional resources based on size-up and department SOP
125
Q

Officers should request assistance from a

A

Qualified elevator mechanic

126
Q

A mechanic’s name and contact information can typically be found

A

On the company inspection card in the elevator control room or through on-site maintenance

127
Q

Common electrical failures in elevators may include

A
  • faulty interlocks on hoistway doors
  • blown fuses
  • shorted electric cables

    -breaks in operating circuits
128
Q

Located in the machine room may indicate the stalled car’s location

A

Controller

129
Q

When working near an open hoistway door especially if the door is fully opened and chocked personnel must have

A

A lifeline attached

130
Q

Passengers should be advised not to activate this button. If already activated, they should be advised to reset the switch.

A

Emergency stop switch

131
Q

After personnel have located the stalled elevator and communicated with passengers to assess their health status, officers should determine if the incident is

A

Nonemergency or emergency in nature

132
Q

Personnel can instruct passengers to perform self-rescue techniques. If these fail personnel should
