It is essential that the users of a full body harness receive proper training and instruction, including detailed procedures for the safe use of such equipment in their work application. ANSI/ASSP Z359.2, “Minimum Requirements for a Comprehensive Managed Fall Protection Program”, establishes guidelines and requirements for an employer’s managed Fall Protection program, including policies, duties and training; Fall Protection procedures; eliminating and controlling fall hazards; rescue procedures; incident investigations; and evaluating program effectiveness. Correct fit of a Full Body Harness (FBH) is essential to proper performance. Users must be trained to select the size and maintain the fit of their Full Body Harness. Users must follow manufacturer’s instructions for proper fit and sizing, paying particular attention to ensure that buckles are connected and aligned correctly, leg straps and shoulder straps are kept snug at all times, chest straps are located in the middle chest area, and leg straps are positioned and snug.
