When laborers are at work in a scaffolding set they are usually protected by a guard rail that is ideally placed at a height of two feet at each level. However, there are times when a scaffolder climbs to a higher level before the establishment of the guard rail. This is usually when the new level is being installed in the scaffolding set up.
The height guard is an edge protection system that ensures edge protection in the absence of the guard rail. It can be lifted from a lower level to the next level before the scaffolder has climbed up. It is a triangular structure designed to extend between two consecutive levels by taking the support of a guard rail in the lower level to give edge protection to a climbing worker in the next level. Check out the working of this height guard in the video here.
