Fall Protection & Fall Arrest Systems for the Power Transmission Industry

OSHA-compliant fall protection for high tension power lines keeps your linemen safe and power transmission systems online.  Providing safe access to power lines suspended at significant heights requires a comprehensive fall prevention strategy, which includes the proper mix of fall protection equipment, a descent and rescue plan, personnel training, and partnering with a fall protection company that appreciates the unique nature of the potential fall hazards associated with your industry.

Design Considerations

Power Transmission Fall Protection Design Considerations

The power transmission market involves high tension power lines that are typically elevated at heights ranging from 75 to 300 feet.  Power lines are typically placed in rural areas, making accessibility a challenge.  Servicing high tension power lines exposes workers to fall hazards as they climb ladders or pegs from the ground level to the service platform and then as they transition to a platform which is typically at a 90 degree angle from the vertical ladder.  Power transmission lines typically lack safety cages to protect workers from falls and it is not uncommon for linemen to service these installations in inclement weather.

OSHA Regulations

  • HLL/VLL
    • 1926.502(d)
      'Personal fall arrest systems.' Personal fall arrest systems and their use shall comply with the provisions set forth below. Effective January 1, 1998, body belts are not acceptable as part of a personal fall arrest system. Note: The use of a body belt in a positioning device system is acceptable and is regulated under paragraph (e) of this section.
    • 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.
    • 1926.502(d)(9)
      Lanyards and vertical lifelines shall have a minimum breaking strength of 5,000 pounds (22.2 kN).
    • 1926.502(d)(10) 1926.502(d)(10)(i)
      Except as provided in paragraph (d)(10)(ii) of this section, when vertical lifelines are used, each employee shall be attached to a separate lifeline.
    • 1926.502(d)(11)
      Lifelines shall be protected against being cut or abraded.
    • 1926.502(d)(12)
      Self-retracting lifelines and lanyards which automatically limit free fall distance to 2 feet (0.61 m) or less shall be capable of sustaining a minimum tensile load of 3,000 pounds (13.3 kN) applied to the device with the lifeline or lanyard in the fully extended position.
    • 1926.502(d)(13)
      Self-retracting lifelines and lanyards which do not limit free fall distance to 2 feet (0.61 m) or less, ripstitch lanyards, and tearing and deforming lanyards shall be capable of sustaining a minimum tensile load of 5,000 pounds (22.2 kN) applied to the device with the lifeline or lanyard in the fully extended position.
  • Personal Fall Arrest Systems
    • 1926.502(d)
      'Personal fall arrest systems.' Personal fall arrest systems and their use shall comply with the provisions set forth below. Effective January 1, 1998, body belts are not acceptable as part of a personal fall arrest system. Note: The use of a body belt in a positioning device system is acceptable and is regulated under paragraph (e) of this section.
    • 1926.502(d)(16)
      Personal fall arrest systems, when stopping a fall, shall:
    • 1926.502(d)(16)(i)
      limit maximum arresting force on an employee to 900 pounds (4 kN) when used with a body belt;
    • 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.
  • Ladders
    • 1926.1053(a)(18)
      Fixed ladders shall be provided with cages, wells, ladder safety devices, or self-retracting lifelines where the length of climb is less than 24 feet (7.3 m) but the top of the ladder is at a distance greater than 24 feet (7.3 m) above lower levels.
    • 1926.1053(a)(19)
      Where the total length of a climb equals or exceeds 24 feet (7.3 m), fixed ladders shall be equipped with one of the following:
    • 1926.1053(a)(19)(i)
      Ladder safety devices; or
    • 1926.1053(a)(19)(ii)
      Self-retracting lifelines, and rest platforms at intervals not to exceed 150 feet (45.7 m); or
    • 1926.1053(a)(19)(iii)
      A cage or well, and multiple ladder sections, each ladder section not to exceed 50 feet (15.2 m) in length. Ladder sections shall be offset from adjacent sections, and landing platforms shall be provided at maximum intervals of 50 feet (15.2 m).
