Effective protection from accidental trapping of fingers between the door leaf and the door frame

Power-operated doors pose a hazard to vulnerable people (e.g. children) in all areas that are open to the public. The absence of safeguards result in repeated accidents with injuries related to trapping. Athmer finger protection systems prevent injuries and have proven themselves in practice for more than 30 years.

DIN EN 16005

Safety in use - Requirements and test methods

The DIN EN 16005 standard defines the safety requirements and test methods for power-operated doors.

DIN EN 16005 is a harmonised European standard which applies in all CEN member states. As a result, the requirement of safeguarding the closing edges of power-operated doors applies throughout Europe. The DIN EN 16005 standard has been in force since April 2013. Before this, similar requirements were stipulated in the standard DIN 18650 for automatic door systems which was came into force in July 2006.

The following points in relation to the safety of the closing edges of doors are defined in the standard:

  • Power-operated doors designated as automatic door systems are all doors whose wings are not moved by manual or stored energy but with an external (e.g. electrical) power supply.
  • Power-operated doors must be designed so as to prevent or safeguard against crushing, shearing, knocking or draw-in hazard points during opening and closing. (DIN EN 16005, 4.6.1)
  • Hazard points which present a risk of entrapping fingers on the secondary closing edges between the door leaf and the door frame must be prevented by the design or separating or switching protective devices must be provided. (DIN EN 16005,

    This is shown in the following illustration:

    (DIN EN 16005, Fig. 3: Examples of safety measures on hinged doors)

  • Safety devices on the closing edges which safeguard against a finger trapping hazard must be designed so as to safeguard hazard points on the door leaf (between the bottom and the top of the door leaf) up to a height of at least 2,000 mm above the floor surface. (DIN EN 16005, 4.6.1 b)

EC Machinery Directive 2006/42/EC

For the purpose of the EC Machinery Directive 2006/42/EC, power-operated doors are machines (directive 2006/42/EC, art. 1, paragraph 1, item a, art. 2, item a). For this reason, the manufacturer or the manufacturer’s agent is required to carry out a risk assessment before a power-operated door is brought onto the market, in order to ascertain the relevant health and safety protection requirements (directive 2006/42/EC, Annex I (1).

The risk assessment is regulated by DIN EN ISO 12100. For this reason, crushing and shearing hazards on the closing edges must be  identified. The door must be designed and built to take account of the results of this risk assessment. The manufacturer is deemed to be whoever assembles the door and actuator and launches them onto the market. In the case of hinged doors, this is generally the metalworking company. Once door systems have been acceptance tested, the responsibility for their safe working order and operation passes to the operator of the door system.

DIN 18040 – Barrier-free construction

The DIN 18040 standard defines the technical conditions according to which buildings and structures are barrier-free. The aim of this standard is to permit virtually all people to use constructed living spaces in the generally usable way, without any particular difficulty and in principle without help from other people by designing these spaces as barrier-free areas.

The DIN 18040 standard defines that doors must open and close with a minimum of effort. As an example, operating forces of 25 N for opening the door leaf of hinged doors and sliding doors are specified.

If it is not possible to achieve this, e.g. with heavy entrance doors, or fire and smoke doors, the use of power-operated doors is prescribed. In this case, the standard DIN EN 16005 also applies here, including the previously described safety requirements.

ASR A1.7 – Doors and gates

The ASR workplace regulation reflects the technical state of the art, occupational medicine and occupational hygiene and other established findings of occupational research for setting up and running workplaces.

The ASR A1.7 applies for setting up and operating doors and gates in buildings and on the premises as well as in commercial facilities located on the premises of a business or a building site and which employees have access to as a result of their work.

In the case of power-operated doors and gates, an effective safeguard against mechanical hazards must be available up to a height of 2.50 m from the ground or from another permanent access level. This can be achieved by a single measure or a combination of the following safeguarding measures: (ASR A1.7, section 6)

  • Keeping a safe distance
  • Installation of separating protective equipment at the closing edges, such as housings, covers, panelling, fixed protection wings
  • Suitable shaping of wing surfaces and protruding parts
  • Installation of switching protective devices (pressure sensitive or touch-free protective devices)
  • The effort required for opening or closing by hand should not exceed  220 N for doors, and 260 N for gates.
