Data record gloss.restricted-approach-boundary.osha1910-269.ergonomic-component

Verified 2026-10-28 Confidence: High

Appendix B to 29 CFR 1910.269 explains that a minimum approach distance includes an adder for the inadvertent movement of the worker relative to an energized part, or of the part relative to the worker, called the ergonomic component; the employer adds it to the electrical component to arrive at the total minimum approach distance used in live-line work. The explanation sits in section III.D of the appendix.

    Read the reference passage
    "The minimum approach distance must include an "adder" to compensate for the inadvertent movement of the worker relative to an energized part or the movement of the part relative to the worker. This "adder" must account for this possible inadvertent movement and provide the worker with a comfortable and safe zone in which to work. Employers must add the distance for inadvertent movement (called the "ergonomic component of the minimum approach distance") to the electrical component to determine the total safe minimum approach distances used in live-line work."
