Calculating fall clearance -  The use of a "Personal Fall Arrest System" is something that, on the surface, doesn't seem to be that
complicated but quite often is either not done at all or done incorrectly. With the broad spectrum of fall arrest equipment
that has come onto the market in recent years, knowing how to calculate fall clearance based on one simple equation simply is no longer feasible.

This Webinar will cover the intricacies of calculating clearance for the main types of fall arrest systems in-use today, showing how the process varies and giving tips on working to simplify the process. The main focus of the presentation will include a discussion on (1) why this topic is important to understand and, then, (2) quickly transition to talking about how to figure out system space requirements for applications such as utilizing energy-absorbing lanyards, self-retracting lifelines, horizontal lifelines, and vertical lifelines.Time will be taken to discuss general rules that can be applied in each of the above-mentioned situations, while directing the listener back to instructions provided with their particular systems. Emphasis will be put on how recent regulations have truly added many "variables" to our calculations.

  • Basic strategies for calculating clearance with the two main types of connecting devices--EALs & SRLs--will be discussed
  • Explaining fall clearance calculations with simpler systems, further time will be spent discussing applying their use on horizontal and vertical lifelines.
  • The learner will select the CORRECT formula for calculating clearance, based on a proposed scenario and equipment being used.
  • Time will be taken to discuss how new (1) regulations and (2) technologies have changed how fall clearance is calculated.
  • Strategies will be given as general rules for always knowing how to safely calculate clearance based on system types and user needs.

Chris Irwin, ASHM, is a global fall protection trainer and safety program developer with MSA, having worked in the development of both fall protection and confined space entry training programs for the company. Having received a Bachelor of Sciences degree in Safety and Health Management, Chris began his career at an OSHA Voluntary Protection Program (VPP) Star manufacturing facility as an Environmental, Health, and Safety specialist before moving on to work as a site safety supervisor for the general contractor of a construction company tasked with building a dual-cycle power plant. Since 2009 Chris has worked full-time as a safety trainer for open enrollment and contractual trainings in everything from basic fall protection, competent person, and train-the-trainer programs to tower, wind turbine, and confined space rescue. Besides training, he has also worked extensively carrying out on-site OSHA-style safety inspections pertaining to all areas of the 1910 and 1926 regulations, consulting with safety managers to establish corporate programs and policies. Additionally, Chris is a certified OSHA 10 and 30-Hour trainer for both General Industry and Construction. Prior to entering the safety field Chris worked as a Spanish teacher in a rural Pennsylvania high school for grades 7 through 12.
