Restraint as the name suggests prevents a person from getting into a position where a fall could possibly take place. A restraint system is usually a simple system involving the use of a fixed point and a lanyard of a specific length. The lanyard should be shorter than the length of the distance to where a fall could take place.
A knurled threaded sleeve is secured into the structure with a two-part resin system. Once cured an eyebolt is screwed into the insert to the required torque setting. The anchor is then tested by attempting to pull it back out of the structure in the direction it went in. Restraint eyebolts can also be installed in structural steel.
BS 8437:2005 Code of practice for selection, use and maintenance of personal fall protection systems and equipment for use in the workplace, states that the anchorage should be able to withstand twice the mass it is ever likely to be subjected to. Once installed the anchor will have a calibrated test rig set up on it and the anchor tested to the relevant force.
Once the installer has carried out all the testing and inspection, certification will be issued for the use of the eyebolts.
The eyebolts should have a visual inspection by the user every time they are to be used and be re-tested annually.
