UNI-TRACK Fall Arrest System

UNI-TRACK is a lightweight horizontal rigid track fall arrest system, designed from the worlds most recognized name in structural support, UNISTRUT. Most UNI-TRACK fall arrest installations occur indoors, with the system attaching to the underside of the building’s roof framing steel. This cost-effective, modular fall arrest system is an incredibly versatile alternative to more expensive, custom trolley beam systems and provides excellent fall protection for workers performing tasks above tanks, machinery, semi-truck trailers, and more.

One of the most important considerations when contemplating installation of a UNI-TRACK fall arrest system is the strength of the building’s roof trusses.  This is why our engineers conduct an on-site visit and perform calculations to determine if the truss system is strong enough to support the UNI-TRACK system.  After the engineering review and installation are completed, you’ll enjoy years of safe and reliable service from your UNI-TRACK system.

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.
