Powered Gate Crushing and Trapping Prevention
A Moving Gate Can Trap More Than a Vehicle

At shift change, a worker may try to follow a vehicle through an automatic gate. The closing edge is only one danger: the opening movement can also trap someone beside a wall or fence. Treat the whole travel area as machinery space, including the section where a sliding gate runs back.
Controls to confirm
- Keep people clear: use the designated pedestrian entrance and stay outside the gate's full movement area. Report missing guards or access to trapping gaps; do not reach through the gate or follow vehicles through it.
- Confirm protective functions: arrange competent inspection and the checks specified in the gate instructions, including safety edges and any required force tests. A vehicle-detection beam alone does not prove pedestrian protection. Never test the gate with a person or bypass a protective device.
- Prepare for a fault or entrapment: ensure responsible staff know the approved stopping, isolation and emergency-release procedure. If protection is damaged or unreliable, stop use, secure the area and obtain competent repair. Leave the gate safe and verify protection before returning it to service.
Today’s action
Walk the entrance with the responsible supervisor from outside the movement zone. Confirm the pedestrian route, guard condition, inspection status and access to emergency instructions; resolve defects before use.
