Lift incidents can be categorised into two distinct incident types: |
• Person shut in lift’ (PSIL). Where people are stranded in a lift car which has stopped moving or the doors have failed to open. This is normally due to an electrical or mechanical malfunction • ‘Person trapped in a lift’ (PTIL). Where people are trapped by the lift, its operating mechanism or machinery. This is a much more serious special service that will attract an enhanced LFB attendance |
|
|
Brigade Control operators apply a method of call filtering to determine the type of response that will be made to a lift incident. They are: |
• If the lift occupant is likely to be seriously ill (a medical emergency), the LFB will respond immediately i.e. emergency mobilisation. One pumping appliance will be mobilised • If no one is in imminent danger and the lift owners routine release arrangements are not available or do not exist, the LFB will attend at normal road speed. Non-emergency mobilisation. One pumping appliance will be mobilised
• If no one is in imminent danger and there are release arrangements in place the LFB will not attend • If the information received suggests the person(s) involved is trapped, Brigade Control will mobilise as for a special service emergency. Two pumping appliances and one FRU will be mobilised. |

What are the are two main types of lift which you are likely to encounter operationally? |
• Traction or cable lifts Generally these types of lift have steel cables attached to the lift car which go up the lift shaft to the lift motor or lift machine room. The machine room is normally situated above the lift shaft • Hydraulic lifts Hydraulic lift systems differ from traction systems in that hydraulic lifts only drive in the upwards direction. Hydraulic oil from a reservoir is forced into the system by a pump to raise the lift car. For downward travel the hydraulic oil is pushed back into the reservoir by the weight of the lift car |

There are a number of variations to this type of lift: |
• Geared lifts This is the most common type of lift drive system. Often used in residential properties of three or more stories. A motor attached to a shaft, drives the main hoist or drive sheave through a gearbox. The lift car and counterweight are suspended on steel cables or ropes which sit in grooves on the drive sheave. The weight of the car and counterweight force the cables into the grooves on the drive sheave to create traction and the lift car is raised or lowered when the drive sheave turns. The speed at which the drive sheave turns is controlled by the gearbox
• Gearless Normally found in high rise buildings. Operates at high speed in a similar way to ‘geared lifts’ but without the gearing system • Machine room less lift (MRL) or space saver lift The common feature of all MRL lifts is that the machinery and equipment is housed within the lift well. Conventional hand winding or manual lowering is not possible due to the remote location of equipment. A panel on one of the landings (usually the top floor) will contain basic controls to allow the lift to be operated remotely |

There are two types of hydraulic lift: |
• Direct Where the lift car sits directly on top of a hydraulic ram. Hydraulic oil is pumped from a reservoir into a ram, which raises the lift
• Indirect Where a hydraulic ram is extended or shortened and operates cables or chains attached to the the lift car, via a pulley at the top of the ram |

|
Information must be gathered and recorded in accordance with policy number ____ - information gathering/contingency plans. |
Policy number 800 |
|
|
Information gathering should take place when visiting premises with lifts and should include the following: |
• Access arrangements • The height and number of floors • The type(s) of lifts installed • The location of lift motor rooms and safety control mechanisms • Availability and call-out arrangements for lift engineers • Safety features of the machinery • Availability and location of equipment operating instructions |
|
|
Full firefighting PPE must be worn at all lift incidents. The IC may allow crew members to temporarily reduce the level of PPE for a specific task or activity such as, ascending stairs to reach the lift motor room. The following equipment should be taken into the building: |
• Two incident ground radios • Lift and Gerda Keys • Immediate Emergency Care (IEC) bag • Crowbar or Halligan tool |
|
|
The following information will assist in formulating a release plan for people trapped in a lift: |
• Number of persons in the lift car and their condition • Maximum capacity of the lift car • Type of lift • Location of machine room • Location of the lift car (may be between floors) |
|
|
If the lift car needs to be moved to floor level or the power supply needs to be isolated, a minimum of two personnel should be sent to the lift machine room. The crew should take with them: |
• Hand held radios • LFB and Gerda keys • Hand held lamps |
|
|
Only when confirmation has been received from the scene of operations can the crew begin to operate the lift machinery and wind the lift in the direction agreed. The safety equipment usually comprises of a ______ _________ ______ and a _________ _______. |
• brake release lever • winding wheel |
|
|
There are many potential hazards that could be encountered at a lift incident. The following list is not exhaustive.
Staff should be aware of: |
• The risk of electric shock or electrocution • The risk of falling from a height • The risk of entrapment or impact injury • Exposure to oil and grease • Exposure to other hazardous substances • Restricted working spaces • Distressed, agitated or aggressive members of the public |
