This calculator provides a general estimate only. Calculations are based on a default energy absorber deployment allowance of 1.2m and a built-in 1m safety margin.
Fall arrest systems must be assessed by a competent person using the specific equipment instructions, site conditions, anchorage position, and rescue requirements. All system lengths, harness attachment position, available clearance, carried equipment, and worker height must be accurately measured and considered. Additional factors including swing fall hazards, system stretch, compatibility of components, and manufacturer instructions may affect the actual clearance required.
