Safe Operation of Sliding Metal Doors in Public Areas

t501-32

Sliding door finger safety design depends on controlling the gaps where fingers can be trapped, rounding or covering leading and trailing edges, and selecting motion and sensing systems suited to public traffic. Specify the gap limits and sensor behaviour early, and confirm the final values with the project's safety engineer and the applicable Israeli standards.

Why finger entrapment happens on sliding doors

Finger injuries on sliding doors usually occur in the gap between the moving leaf and the frame, or between the leaf and a fixed wall or post. Children and older users are most at risk because their hands are often at the height of the closing edge and they may not react quickly when the door moves.

In public buildings, traffic is constant and users are not always attentive, so the design must assume that hands will reach into the gap. Good design removes the trap rather than relying on warning signs.

Controlling gaps and clearances

The most effective measure is to keep every gap that a finger could enter below a safe dimension, and to avoid pinch points where two surfaces move towards each other. Track assemblies, roller housings and the transition between frame and leaf all need checking on the drawings.

Edge profiles and surface detail

Sharp edges and exposed corners can cause cuts as well as trapping. Specify rounded or capped profiles on leading and trailing edges, and make sure any sealing strips or brushes are fixed securely so they do not tear loose in daily use.

For metalwork in stainless steel or powder-coated aluminum, finish quality matters. Smooth, well-ground joints are easier to keep clean and do not create hidden hooks that catch fingers or clothing.

Sensors, reversing and automatic operation

Automatic sliding doors should be fitted with presence detection that stops or reverses the leaf when an object is in the path. The sensor coverage must match the door's opening speed and the traffic it serves, including the zone close to the closing edge.

Consider also the force needed to stop the door and the behaviour during a power failure. The sensing and control system should be specified by a qualified installer and tested before handover.

Manual sliding doors in public use

Manual doors rely on the user, so the design should make them easier to control. Hand-grip positions placed away from the closing edge, and a damping or soft-close mechanism, reduce the risk of sudden movement and keep fingers clear of the gap.

Where a manual door is used by children or visitors unfamiliar with the building, add clear visual cues and avoid placing the handle where a hand naturally rests in the gap.

Specifying and checking with the project team

Include finger safety requirements in the door specification from the start, not as a late addition. Give the fabricator drawings showing gap locations, edge profiles and the intended mode of operation, so the factory can build the safety details into the frame and leaf.

Before installation, check the completed door against the specification on site, and record the tested gaps and sensor response. This documentation supports handover and future maintenance.

Frequently asked questions

What is the main cause of finger injuries on sliding doors?

Most injuries happen where a finger can enter a gap that closes as the leaf moves. Removing or limiting those gaps in the design is the most reliable protection.

Do automatic sliding doors need sensors for finger safety?

Presence sensors that stop or reverse the door are an important safeguard for automatic doors in public areas. Their coverage and response should be set by a qualified installer.

Which edge details help reduce risk?

Rounded or capped leading and trailing edges and securely fixed seals reduce both trapping and cutting hazards. Smooth finishes also avoid hidden hooks that catch clothing or fingers.

Who confirms the exact safety dimensions?

The project's safety engineer should confirm the exact gap and clearance values against current Israeli standards. Share these requirements with the fabricator at the drawing stage.

Common mistakes to avoid

Designers often leave gaps at track or wall junctions unchecked and add safety features only after fabrication. Both mistakes are costly to correct once the door is installed.

Our recommendation

Mark every potential pinch point on the drawings at the design stage and agree the gap limits with your engineer before the fabricator starts. Ask for a site test of gaps and sensor response as part of handover.

Summary

Safe sliding doors in public areas come from designing out gaps, rounding edges, choosing suitable sensors and specifying clearly from the start. Confirm all values with the engineer and applicable standards.
