Self Retracting Lifelines

Self Retracting Lifelines

Self Retracting Lifelines (also known as SRL or SRL’s) offer an excellent mix of worker safety and productivity.  SRL’s extend and retract automatically as workers move while performing job duties at heights.  In the event of a fall, the braking system engages and disperses the load of the fall through the body harness.  Diversified Fall Protection offers a complete line of OSHA and ANSI compliant self-retracting lifelines (SRL) to keep your personnel safe while working at heights.

 

Design Considerations

  • Light-weight thermoplastic or aluminum construction for maximum durability
  • Wire rope or synthetic lifeline material options for varying environments
  • Sealed SLR's available for harsh and corrosive working environments.
  • Retrieval styles for confined space and rescue applications
  • Built-in rescue (RSQ) allows user to be lowered after a fall either automatically or manually
  • Arc Flash Rated SRL's for electrical applications.
  • Specialized self retracting lifelines leading edge applications.

OSHA Regulations

  • Personal Fall Arrest Systems:  System performance criteria. In addition to the general requirements in paragraph (c) of this section, the employer must ensure that personal fall arrest systems: 1910.140(d)(1)(i)
    • Limit the maximum arresting force on the employee to 1,800 pounds (8 kN); 1910.140(d)(1)(ii)
    • Bring the employee to a complete stop and limit the maximum deceleration distance the employee travels to 3.5 feet (1.1 m); 1910.140(d)(1)(iii)
    • Have sufficient strength to withstand twice the potential impact energy of the employee free falling a distance of 6 feet (1.8 m), or the free fall distance permitted by the system; and... 1910.140(d)(1)(iv)
    • Sustain the employee within the system/strap configuration without making contact with the employee's neck and chin area. 1910.140(d)(1)(v)
      If the personal fall arrest system meets the criteria and protocols in appendix D of this subpart, and is being used by an employee having a combined body and tool weight of less than 310 pounds (140 kg), the system is considered to be in compliance with the provisions of paragraphs (d)(1)(i) through (iii) of this section. If the system is used by an employee having a combined body and tool weight of 310 pounds (140kg) or more and the employer has appropriately modified the criteria and protocols in appendix D, then the system will be deemed to be in compliance with the requirements of paragraphs (d)(1)(i) through (iii). 1910.140(d)(2)   The employer must ensure that:
    • On any horizontal lifeline that may become a vertical lifeline, the device used to connect to the horizontal lifeline is capable of locking in both directions on the lifeline. 1910.140(d)(2)(ii)
    • Personal fall arrest systems are rigged in such a manner that the employee cannot free fall more than 6 feet (1.8 m) or contact a lower level. A free fall may be more than 6 feet (1.8 m) provided the employer can demonstrate the manufacturer designed the system to allow a free fall of more than 6 feet and tested the system to ensure a maximum arresting force of 1,800 pounds (8 kN) is not exceeded. 1910.140(d)(3)
    • Body belts. Body belts are prohibited as part of a personal fall arrest system.
