Continuous Pass Through Systems

Continuous Pass Through Lifelines

A continuous pass through horizontal lifeline design allows workers to move through multiple spans of a HLL system with 100% tie-off at all times.  Horizontal lifelines with automatic pass through eliminate the need for workers to un-clip from the HLL to move past intermediate anchor points, keeping both hands free at all times.  Easy to use continuous pass through or hands-free horizontal lifeline systems are ideal for narrow work areas and offer a mix of unencumbered movement and fall protection that maximizes worker productivity.

Design Considerations

Continuous Pass Through Horizontal Lifeline Design Considerations Constructed from stainless steel components, continuous pass through horizontal lifelines offer exceptional corrosion resistance and component longevity. The distance spanned by a horizontal lifeline with continuous pass through is limited only by the ability to attach a series of anchor points to surrounding structure; crane rail HLL systems can safely span distances in excess of 600 feet.  Our fall protection safety specialists can engineer an automatic pass through horizontal lifeline system to accommodate the special characteristics of your elevated work area, from corners to the absence of pre-existing anchor points and more. Each anchor point must be secure enough to withstand the forces generated by a fall and all sections of the HLL must be assessed to ensure that workers do not strike pipes, equipment, or other surfaces below before a fall can be arrested. Special care must also be taken to account for load and deflection rates which are determined by a number of factors, including pre-tension of the cable, length of the area spanned, and the number of workers connected to the system.

OSHA Regulations

  • Horizontal Lifelines
    • 1926.502(d)(8) Horizontal lifelines shall be designed, installed, and used, under the supervision of a qualified person, as part of a complete personal fall arrest system, which maintains a safety factor of at least two.
  • Personal Fall Arrest Systems
    • 1926.502(d)(16) Personal fall arrest systems, when stopping a fall, shall:
    • 1926.502(d)(16)(ii) limit maximum arresting force on an employee to 1,800 pounds (8 kN) when used with a body harness;
    • 1926.502(d)(16)(iii) be rigged such that an employee can neither free fall more than 6 feet (1.8 m), nor contact any lower level;
    • 1926.502(d)(16)(iv) bring an employee to a complete stop and limit maximum deceleration distance an employee travels to 3.5 feet (1.07 m); and,
    • 1926.502(d)(16)(v) have sufficient strength to withstand twice the potential impact energy of an employee free falling a distance of 6 feet (1.8 m), or the free fall distance permitted by the system, whichever is less.
