While vertical safety climb systems are widely used on antenna supporting structures, there is an increasing use of horizontal lifelines.

This PAN provides insight on the standards and processes in which horizontal lifelines are to be designed, installed, and maintained to ensure proper fall protection for trained workers. When incorporating horizontal lifelines, it is important to understand these standards and when horizontal lifelines must be part of an overall fall protection plan. The following topics are explored:

  • Incorporating Horizontal Lifelines into Overall Fall Protection Plan
  • Temporary vs. Permanent Lifelines
  • Horizontal Lifelines and their Supporting Structures
    • ANSI/ASSP A10.48
    • ANSI/TIA 222
    • ANSI/TIA 322
  • Rooftop Applications
    • ANSI Z359.18
