The leading edge fall protection system is designed to control the unique fall hazards posed by leading edge work. The leading edge fall protection system provides an anchor at seven feet above the deck, creating a smaller fall distance than conventional methods, which are anchored below shoulder level.What is a positioning device system?
According to the definition found in the standards, a positioning device system is a “body belt or body harness rigged to allow an employee to be supported on an elevated vertical surface, such as a wall, and work with both hands free while leaning.” Think about an iron worker who is tying rebar for a pour-in placeWho is authorized to enter an area protected by a safety monitoring system?
