Service Delivery 2 Lifts and Machinery Rescues
Aim To provide students with information to enable them to deal with lift incidents.
Learning OutcomesAt the end of the session the student will: • Know the role of the fire service at lift incidents and rescues involving machinery • Be aware of the component parts of lifts and escalators • Know how to rescue, and minimise harm to, persons shut in lifts and mechanisms • Recognise the hazards and risks associated with lifts and escalators.
Lift Rescues Two categories; • Where persons are shut in the lift car and it has stopped between floors • Where persons are trapped in the mechanism.
Electric lifts • A ‘car’ suspended by steel ropes from a winding machine • Guides • Remote control system • Counterweight (weight of lift car +50% of the load) • Safety devices.
Electric lift Car framework.
Lift car • Framework supports • Car body – some have trap door in roof • Safety gear • Lifting ropes.
Component parts • Driving mechanism - electric motor • Safety devices • Gates, doors and keys.
Hydraulic lifts Differ from electric lifts as follows; • Usually only up to 4 floors • Powered by a hydraulic pump operating a ram fixed to the car (direct) or via chains or ropes attached to the top of the car (indirect) • Direct systems have different safety gear.
Hydraulic lifts Direct Indirect.
Rescues from lifts(1) • Find out the nature of the incident • Identify occupants and type of lift • Two firefighters to the motor room • Isolate the power supply.
Rescues from lifts(2) • Contact lift engineer • Determine need for medical assistance • Effective communications essential • Contact the public affected • Hand wind to nearest/easiest landing • Leave in a safe state.
Machinery rescues The Incident Commander will; • Carry out a risk assessment • Control power to the machinery • Liaise with site engineer • Summon medical assistance • Ensure all equipment is used safely • Supervise closely.
Safety • Dynamic risk assessment • Use personnel / equipment safely • Supervision.
ConfirmationAssessments will be based on this lesson and the corresponding study note Learning Outcomes • Know the role of the fire service at lift incidents and rescues involving machinery • Be aware of the component parts of lifts and escalators • Know how to rescue, and minimise harm to, persons shut in lifts and mechanisms • Recognise the hazards and risks associated with lifts and escalators.
