Fall distance and clearance calculations
ASP video lesson, 5:53. ASP Domain 1: Mathematical Calculations
Narrated with an AI-generated voice. The script is AI-drafted from the cited rules and fact-checked against them.
Work the ASP fall clearance math: the 6-foot free fall limit, 3.5-foot deceleration distance, arresting force limits, and how to add up the clearance needed below the anchorage.
Included with every ASP pass, with captions, chapters and the full transcript. Every rule and number is cited on screen to its primary source.

What this lesson covers
In this lesson, you'll learn to: state the free fall and deceleration distance limits, recall the maximum arresting force limits, add up the clearance needed below the anchorage, and apply the 310-pound weight and impact-energy strength criteria. Under 1926.502(d)(16), a personal fall arrest system sets two distance limits.
