Fall distance and clearance calculations
ASP written lesson, 8 min read. ASP Domain 1: Mathematical Calculations
AI-drafted from the cited rules and fact-checked against them. Study aid, not site-specific safety advice. The official rule controls.
What you'll learn
- State the free fall and deceleration distance limits for a fall arrest system
- Recall the maximum arresting force for a harness and for a belt
- Add up the clearance needed below an anchorage
- Decide whether an available clearance is adequate
- Apply the 310 pound and anchorage strength criteria
What this lesson covers
Fall clearance math tells you whether a worker will stop before hitting the level below. This lesson covers the free fall and deceleration limits, the arresting force caps, and how to add up the clearance beneath an anchorage, which the exam tests directly.
This lesson is included with a pass
