If the structural design of something is wrong, it leads to safety hazard. This is a geared wheel used to open a shutter to pour concrete. Never had an issue with it until recently some feedbacks came that there may be a trapping hazard or its too close to the skip. I am referring to the closest...
HI All,
DO we have a regulation or standard govering the minimum distance between the geared wheel and the skip surface to prevent any trapping hazards ?
thank you
