A. Anchorage (Anchor point)
A fall arrest anchor point can be a batten on a pitched roof, a concrete eyebolt or a tripod for hoisting in a well or similar. If the anchor point is used to arrest a fall, it must be able to withstand a pull of 12 kN (approx. 1200 kg.) Stopping a fall also requires that the length of free fall is limited as much as possible. Therefore, the anchor points should be placed higher than the user, or at least 2 meters from the edge of a roof. On flat roofs, an anchor point will typically be a standalone safety foot or wire system to allow for inspection or service on the roof. As it is intended for this purpose, a CE mark must be clearly visible on the foot/wire system.
To be eligible for a CE mark, it must be tested in collaboration with the Institute of Technology.
- EN795:2012 for personal protective equipment.
- CEN/TS 16415:2013 for safety equipment for use by multiple persons (max 4 persons).
Hereit undergoes a dynamic drop test and static pull test.
Dynamic drop test procedure
EN 795:2012
- 100 kg of mass is dropped at a drop height that measures a tensile value of 9 kN.
- While the 100 kg is left hanging, add 200 kg.
- The total of 300 kg. must hang for 3 min. to ensure that the system does not give in.
CEN/TS 16415:2013
- 200 kg is dropped at a drop height so it measures a tensile value of 12 kN.
- While the 200 kg. is hanging, drop 100 kg. 1.5 m and then repeat with another 100 kg. (200 kg. = 2 persons + 100 kg. per additional person)
- The total of 400 kg. is left hanging - then the weight is increased to 900 kg. by adding a 500 kg. mass. The total of 900 kg. must hang for 3 minutes (2 persons = increase to 600 kg. + 150 kg. per additional person = 900 kg.)
Procedure for static pull test
EN 795:2012
- A 1200 kg mass should hang for 3 minutes (1200 kg = 12 kN)
CEN/TS 16415:2013
- A 1500 kg mass should hang for 3 minutes (1500 kg = 15 kN)
A fall protection system must undergo an annual service inspection, where a pull test of at least 6 kN will be performed to ensure that the anchorage still has wood in the roof structure.
