Work positioning belts are used for two main purposes for those working at height. They are commonly used as restraint belts; meaning that the belt us worn by a person who is working close to a potential fall. The person therefore sets up a height safety system that makes it impossible for him / her to reach the falling edge often using a restraint belt and an adjustable restraint lanyard. This is working with restraint rather than fall arrest and therefore because the restraint system makes it impossible for them to reach the fall zone shock absorbing fall arrest equipment is not needed. The other main use is as a work positioning belt; used in conjunction with an EN360 fall arrest harness to give the benefits of an EN360/EN358 harness.
