An entrapment is rarely dangerous by itself; the risk comes from what people do while waiting, and from an improvised rescue. A practiced procedure removes both.
First contact: what the car occupant needs
- Establish two-way communication and keep it open. Tell them they are safe in the car and that a qualified person is coming.
- Ask for the number of people, any injuries, any medical need, and whether the doors are open at a landing.
- Instruct them not to attempt to leave the car, not to force the doors, and not to climb out through a partial opening.
- Give a realistic timeframe and stay in contact until the responder arrives.
The responder’s sequence
- Confirm the car position precisely before doing anything – landing, between landings, and which direction.
- Apply the required lockout and confirm zero energy before manual intervention.
- Use the machine-specific release method. Manual lowering, brake release and rescue procedures differ between traction, hydraulic and MRL units, and between manufacturers.
- Bring the car to a landing, confirm the interlock is engaged and the doors will remain open, then assist people out.
- Keep the unit out of service until the cause is identified – the entrapment may be the first sign of a defect that will repeat with a different passenger group.
Communication systems: test them like safety equipment
The emergency communication device is a code-required safety feature. Test it at the interval your maintenance program states, verify the receiving end actually responds, confirm the power source under a loss-of-power condition where required, and record it. A device that rings an empty office at night is not providing the required function.
Follow-up that prevents a repeat
- Identify the cause and classify it: door, safety chain, drive, power, or misuse (overload, held door, debris).
- Search the history for the same unit and the same cause. A repeating door cause needs a repair, not another reset.
- If a passenger forced the doors, inspect the entrance before returning the unit to service.
Never let a non-qualified person attempt a rescue from the pit or the car top. Building staff can maintain communication and keep people calm; extracting people from a stopped car requires the proper training and equipment.
