1.6.2 Travel Restraint System

A travel restraint system allows a worker to travel just far enough to reach an unprotected edge but not far enough to fall over. The basic travel-restraint system consists of

  • CSA-approved full body harness
  • Lanyard
  • Lifeline
  • Rope grab to attach harness or lanyard to lifeline
  • Adequate anchorage
  • Safety belts, (The use of safety belts is not recommended; however, they are permitted in some jurisdictions.)

There are two methods of travel restraint that are commonly used in construction.

  1. Connecting an anchored lifeline directly to the D-ring of the worker’s full body harness. The lifeline, measured from the anchor point, MUST be short enough to restrain the worker from any fall hazard.
  2. Attaching a lanyard from the D-ring of the worker’s full body harness to a rope grab on an adequately anchored lifeline. There MUST be some way, such as a knot in the lifeline to prevent the rope grab from sliding along the lifeline to a point where the worker is no longer restrained from falling.

Be aware that a fully extended lifeline and/or lanyard that adequately restrains a worker from a fall hazard in one section of the work area may be too long to provide the same protection in another section.
