Options for door safety upgrades in Harpenden
- Fall protection. If a spring, cable or drive fails, the door is caught before it falls.
- Safety edges. Edges on the closing rail detect contact and send the door back up.
- Light curtains. Full-height multi-beam detection across the whole opening.
- Force testing. Closing forces measured against BS EN 12453 limits and recorded.
- Warning devices. Lights and sounders make sure people know when a door is about to move.
What this work can involve
- Upgrading an old relay control panel so monitored safety edges and photocells can be connected to it.
- Fitting spring-break and cable-break devices to older sectional doors installed without any fall protection.
- Force-testing a run of loading bay doors and adjusting closing speeds where results exceed the limits.
Who is responsible for door safety at a site in Harpenden?
In England, two sets of duties meet at a powered door. The installer who supplies or motorises it must hand over a door that meets the Supply of Machinery (Safety) Regulations 2008, tested against BS EN 12453 and documented. The business in control of the premises must then maintain it: regulation 5 of the Workplace Regulations 1992 covers maintenance, and regulation 18 requires upward-opening doors to have a device that stops them falling back and powered doors to have features that prevent trapping.
Planning the work around your site
Where a door is being replaced, the opening has to be made secure at the end of each day. We plan strip-out, any new framing and the new door so the gap is never left open overnight unless you have agreed temporary measures.

Frequently asked questions
Do our powered doors in Harpenden need safety upgrades?
It depends on how they are controlled and used. Doors that close automatically or on a single press typically need edges and photocells or light curtains. A survey and force test shows whether your doors meet current expectations.
Our door at our Harpenden site has a bypassed safety edge. What should we do?
Stop using the door under power until the safety device is working, or use it on hold-to-run only if the risk assessment allows. We can replace the edge or fit alternative detection and re-test the door.
Do you upgrade doors from other installers across Hertfordshire?
Yes. We upgrade safety devices on most makes of powered door across Hertfordshire, whoever installed them, checking that new devices are compatible with the existing control panel and replacing the panel where needed.
