Automatic doors in public buildings or areas can be dangerous for those who need protection (e. g. children). It is fundamental to be able to safely open and close a power operated door in order to gurantee ist safe use.
The doors should be designed to safeguard against crushing, shearing, being hurt and drawn in during the opening and closing of the door; these potential risks must be recognised and eliminated.
Athmer finger protection systems have been preventing injuries for thirty years by effectively reduciong the risk of fingers becoming accidenally trapped in doors.

requirements to barrier-free automatic doors

conforming to EN 16005

Power-operated doors must open and close safely in order to ensure safety in use. For this purpose, a risk assessment must be carried out by the manufacturer of the door system during planning. Power-operated door systems operating in the low energy range can be used for certain applications without safety sensors. However, the danger of crushing and shearing at the secondary closing edge still exists and must be detected and excluded in all cases.

DIN EN 16005 - 4.6.1 b)

Therefore, according to DIN EN 16005 - 4.6.1 b), "Danger points between the leaf and frame, which pose a hazard due to entrapment of fingers, are protected up to a height of 2 m.” and in accordance with EN 16005 - 4.6.3.4 "Danger points at secondary closing edges between sash and frame must be covered with finger protection roller blinds, for example".

Fuse protection according to DIN EN 16005 - 4.6.3.4:
Key: 1 Rubber cover, 2 Rubber or fabric cover, 3 Profile construction (EN 16005, Fig. 3: Examples of safety measures on hinged doors)

The sole protection of the secondary closing edge with sensors should be reconsidered, because these systems have weak points and do not offer 100% safety. Test institutes point out in type examination certificates that in areas where children could play (e.g. in a kindergarten) in addition to sensory protection, mechanical solutions should also be considered! Athmer finger protection systems in special lengths for automatic door applications are the right solution. Provide safety!

risk assessment of barrier-free automatic doors

In cases of doubt, the building operator should have a risk assessment carried out by service professionals on his power-operated doors in order to ensure that his door is safe and complies with the current state of the art in terms of traffic safety requirements (personal safety).

Athmer Fingerschutz® on fire and smoke protection doors

Retrofittable

Athmer Fingerschutz® is suitable for use with fire doors and smoke protection doors. Numerous fire tests have been carried out successfully with door manufacturers / system providers. Athmer finger protection systems have therefore been fitted on fire doors for more than 10 years now and have proven themselves in use. Retrofitting of finger safeguards on fire and smoke protection doors is not regulated by standards. Since neither the product standard (EN 16034) nor the test standard (EN 1634) defines how to test the fire safety of finger protection, finger protection may not be installed on a fire or smoke protection door without the consent of the door manufacturer / system provider. The door manufacturer reserves the right to have the approval of his door extinguished if a structural change is made without consultation with the door manufacturer. The installer / fitter who installs the finger protection system must contact the door manufacturer in advance. Door manufacturers / system providers are familiar with Athmer products and their requirements. By contacting them, they can provide information about a possible retrofit.

Installation approval

The following three options are available for fitting Athmer Fingerschutz® to a fire and smoke protection door:

1. Approval of the door manufacturer / system provider on the basis of a successfully passed fire test carried out by the door manufacturer / system provider

  • Entry in the general technical approval (abZ) or declaration of performance

2. Release of the door manufacturer / system provider due to a non-essential change

  • according to estimates / empirical values of the door manufacturer

3. Approval by the highest building control authority / fire inspectorate on site, taking into account expert opinions and possible substitute measures

  • Release and approval in individual cases (ZiE)

Retrofitting of existing doors according to ASR A1.7

Operator responsibility

The building operator is legally obliged to keep his power-operated door system in a safe condition for use. In the event of damage, which may result from a safety-related obsolete power-operated door system, the operator must reckon with civil law consequences and can be held liable in accordance with § 823 BGB (German Civil Code).

If during regular maintenance by the service technician it is determined that protective devices are missing or do not correspond to the current state of the art, this must be entered in the test logbook and communicated to the operator. In order to comply with the workplace regulation ASR A1.7, the operator must also retrofit older power-operated doors that are already in stock. If this is not done, the operator bears the risk of an accident.

Inventory protection

The argument of inventory protection to avoid retrofitting does not apply, because the power-operated door must be safeguarded according to the state of the art, in this case EN 16005 in conjunction with ASR A1.7.

For this reason, all measures to be taken must clearly aim at eliminating and permanently avoiding the risks associated with the operation of a power-operated door system during its service life.

ASR A1.7

The workplace regulation ASR A1.7 Doors and gates as well as the DGUV Information 208-022 - for doors and gates require: “For power-operated doors and gates, effective safeguards against mechanical hazards must be provided up to a height of 2.50 m above the floor or any other permanent access level.

Athmer therefore recommends that automatic doors should always be safeguarded over the entire height as far as possible.
