An anchorage device (AD) is a system which was specially designed to protect individuals from falling and consists of at least one anchorage point. Anchorage devices are often permanently connected to a building (e.g. flat roof, pitched roof, facade etc.) or to a respective substructure (e.g. machine, crane way, wind energy turbine etc.). Anchorage devices can be combined with personal fall protection equipment (PPE) to provide users with a reliable fall arrest system. An anchorage device is either designed as a preventative retention measure to prevent a fall from occurring or as an arresting system.
As described in DGUV Publication 201-056: "Basic planning guidelines for anchorage devices on roofs", an anchorage system can also comprise several anchorage points. This publication distinguishes between two types of anchor system:
EN 795 differentiates between five basic types of anchorage device.
However, Implementing Decision 2015/2181 of the EU Commission has now changed the scope of application for parts of the EN 795 standard. It stipulates that only types B and E are mobile anchors and, thus, fall within the scope of PPE Directive 89/686/EEC.
You can find further information on this topic in our articles on EN 795 and national technical approval.
In addition to technical anchorage device solutions, so-called anchorage options can also be used to set up a fall protection system. These include, for example, load-bearing pipes, posts or girders that can be used temporarily to attach PPE equipment. In this case, it is important to assess the load-bearing capacity of any structure intended to secure a user on a temporary basis.
In order to be able to enter a danger zone safely, the user has to connect his/her personal fall protection equipment up to the anchorage device. To do this, he/she needs a suitable connector and, of course, a safety harness. Depending on the situation, a guided type fall arrester or self-retracting lifeline licensed for horizontal usage may also be used.
To be able to connect up correctly, the following applies: You should always have an energy absorber to hand.
