SIZE-UP/ASSESSMENT OF CONDITIONS
A. Upon arrival, determine if an emergency exists. Make contact with building representative and occupant(s), and assess the needs: 1. Number of occupant(s). 2. Conditions of occupant(s). 3. Immediate problems. 4. Maintain communication with occupant(s) if possible and inform them of the plan to decrease panic. If unable to communicate with occupant(s), consider incident an emergency response. Determine: 1. Long and short-term effects on the occupant(s). 2. If extrication efforts will produce immediate life saving results, or if waiting for technical assistance would provide for an equal avenue of resolution. 3. If elevator is hydraulic or traction (cable). 4. Best avenue for rescue: a. Car top emergency exit. b. Hoistway door. c. Manual lowering. Locate: 1. Fire key box 2. Doors that provide hoistway access 3. The elevator maintenance room 4. The elevator main power disconnect. 5. If hydraulic, the “manual lowering valve”.

SAFETY CONSIDERATIONS AND CHECKLIST
A. B. C. Do not work in or around elevator or escalator equipment until power is shut off and locked out tagged out. Assign personnel to secure and standby at the main power disconnect (master switch) with radio communications until rescue is terminated. If manual lowering valve does not work, wait for trained elevator technician.

OPERATIONAL GUIDELINES
A. Definitions 1. Buffer Springs – located in the elevator pit, these are what a hydraulic elevator comes to rest on when manually lowered to the bottom floor. 2. Car Door Clutch – Located on the car door, this device couples the car and the hoistway doors together when the car is at floor level. 3. Door Operator – Located on top of the car, this is what controls the opening and

closing of the doors. Typically a wheel type part. 4. Door Restrictor – Typically found on the car door clutch, these mechanical or electro-mechanical devices prevent car doors form being opened when the elevator is between floors. Some are merely long collapsible bars mounted on the back edge of the car door. 5. Equipment (Machine) Room – This is where the machinery necessary to move the elevator is located. It is also where the main elevator power disconnects and the manual lowering valves are located. 6. Fire Key Box – Located at the main egress floor. It should contain hoistway access key, elevator equipment room key, and the fire service key. 7. Flag (lift rod) – Located on the lift rod, this is what the hoistway access key catches to lift the rod and unlock the hoistway doors. 8. Hoistway Access Key – This tool is used to unlock the hall doors in the event that someone is trapped in the elevator. 9. Interlock – Part of every hoistway door. This keeps the hoistway doors locked when the elevator is not at the floor. 10. Lift Rod – Located on the hall door. This connects the pick-up rollers to the latch keeper. 11. Main Power Disconnect – Located in the elevator equipment room, this is what de-energizes or removes power from the elevator. 12. Manual Lowering Valve – Located on the main valve, this is what is used to lower a hydraulic elevator in a rescue situation. 13. Oil Line – Used on a hydraulic elevator. This is what delivers oil from the reservoir tank to the jack. 14. Pick-Up Rollers – Located on the hoistway doors. These are what the car door clutch catches on to unlock and open the hall doors when the elevator stops at the floor. 15. Valve (Main) – Located in the equipment room. This is what regulates oil flow controlling the speed of a hydraulic elevator. This is where the manual lowering valve is located. First in: 1. Make arrival report to dispatch: a. Confirm location (if necessary). b. Situation found. c. Identify side alpha (if appropriate). d. Assume command. e. Identify tactical radio frequency (as necessary). 2. Make contact with building representative, size up incident and make report to 400 units. 3. Announce action plan to 400 units. a. General objectives: 1) Lock out tag out power. 2) Contact occupants. 3) Rescue: a) Through car top emergency exit. b) Through hoistway door. c) By manual lowering.

4) Or, wait for elevator technician (if rescue is not safe or possible). 4. Make assignments (as necessary). 5. Transfer command (as necessary). Duty Officer: 1. Assume command (as necessary). 2. Size-up / assess conditions. 3. Identify command post location. 4. Consider requesting additional resources as necessary a. Medic unit. b. Engine. c. Deschutes County Search and Rescue. d. Elevator Company or building representative. e. Any other additional or heavy equipment needed. 5. Coordinate with building representative. 6. Confirm that elevator service representative has been called and get ETA. 7. Progress Reports: a. “Power has been locked out tagged out.” b. “Occupants have been contacted.” c. “Occupants have exited the elevator.” 8. Termination of incident - secure scene and turn over to building representative. Rescue Procedures: 1. Step 1 – Lock out tag out elevator main power disconnect. 2. Step 2 – Make verbal contact with passengers. Assure them that they are OK and determine if there are any medical emergencies. 3. Step 3 – Determine type of rescue required: a. If rescuing through the car top emergency exit, got to Step 4a. b. If rescuing through a hoistway door opening, go to 4b. c. If “leap frogging” is required go to 4c. d. If rescuing by manual lowering, go to 4d. 4. Step 4 – Rescue types a. Car top emergency exit (can be done with either hydraulic or cable elevator). 1) After lock out tag out of power and contacting passengers, open hoistway door with access key. Prop open. 2) Open car top exit to gain access to inside of car. 3) Remove trapped passengers via ladder lowered into car. b. Hoistway door opening (can be done with either hydraulic or cable elevator). 1) After lock out tag out of power and contacting passengers, open hoistway door with access key. Prop open. 2) Open car doors by pulling on car door clutch or rolling door operator pulleys (may require release of door restrictor). c. Leap frogging – may be necessary if limited hoistway access. Some elevators in mid and high-rise structures have hoistway access door only at the top and bottom floors. If car is stuck somewhere in between, leap frogging is necessary to achieve rescues 4a and 4b. 1) After lock out tag out of power and contacting passengers, go to

top floor with 2nd person. 2) Have 3rd person waiting at hoistway door on floor below. 3) Open top floor hoistway access door with key. 4) While 2nd person spots you, reach down and unlock the hoistway doors at the pick up rollers on the floor below using a pike pole. 5) Tell 3rd person to hold open the hoistway door doors. 6) Allow top floor doors to close and lock. 7) Go down to floor below with 2nd person and send 3rd person to the next floor down. 8) Continue these steps until you reach the elevator. Manual lowering (can be done only with hydraulic elevator). Safest way to rescue passengers from a hydraulic elevator. 1) After lock out tag out of power and contacting passengers, advise passengers to stay clear of car doors. 2) Make sure car doors are completely closed. 3) Go to equipment room and open manual lowering valve until oil stops draining back into tank. 4) Close valve. 5) Go to bottom floor landing and open hoistway door with access key. 6) Push open car doors by grabbing car door clutch (may require release of door restrictor). 7) Allow passengers to step up and out of car. 8) When opening the manual lowering valve, no tools are required. Occasionally, extra leverage is needed to open the valve. Use the machine room key, if necessary. 9) NOTE: If a car does not lower when the manual lowering valve is opened, close valve and call elevator company. DO NOT ATTEMPT RESCUE!
