Is a door a building element or work equipment?
Powered doors carry the risk of crushing, shearing, impact and trapping as they open and close. That is why they are treated separately from manually operated doors. A door is placed on the market as a construction product; but from the moment it enters service in a facility, it must be treated as equipment that requires regular inspection.
Which standards are we talking about?
- EN 13241: the product standard for industrial, commercial and garage doors. It is the basis of CE marking.
- EN 12453: safety requirements for the use of powered doors. Force limits and detection systems are defined here.
- EN 12604: the mechanical aspects and strength requirements of the door.
- EN 12978: the reliability requirements for safety components such as photocells and safety edges.
These documents define with what force a door may close, how quickly it must stop on contact, and how it must behave if the detection system fails. This is exactly where to look when asking a supplier for product documentation.
Indispensable safety components
- Photocell: stops the door closing while a person or vehicle is in the opening, and in most installations reopens it.
- Safety edge: detects an obstacle touching the bottom profile and stops the movement. It is needed for low obstacles the photocell cannot see.
- Force limitation: the motor stops or reverses when it meets resistance above a defined value.
- Anti-fall device: a mechanical lock that stops the panel free-falling if a spring or cable breaks.
- Emergency stop and manual opening: being able to open the door safely when the power is cut is critical, especially for doors on an escape route.
- Marking and warning: yellow-black taping, a warning lamp and a floor line reduce collisions markedly in heavy forklift traffic.
The five shortcomings we see most often on site
- The photocell set only to vehicle height, so pedestrian passage is not detected.
- A photocell lens that has become dirty, or whose alignment has shifted with vibration, going unnoticed for months.
- The manual opening chain jammed somewhere out of reach, or lost altogether.
- The control button moved to a point from which the door cannot be seen.
- The manoeuvring area in front of the door gradually turning into a material storage area.
Why does keeping records help?
Safety components work correctly on installation day; the real question is what state they are in six months later. Which adjustment was made at each service, which part was replaced and the result of the photocell test should all be recorded in writing. That record is the strongest document you can hold, both in occupational safety inspections and in warranty processes.
A safety component is dangerous not on the day it fails, but on the day its failure goes unnoticed.
