Verified 2026-10-28 Confidence: High

Appendix E to 29 CFR 1910.269 explains that the agency considers an employee exposed to electric arc hazards when there is a reasonable likelihood that an arc will occur in the work area, that is, when the probability of an arc is higher than it is for the normal operation of enclosed equipment. The explanation sits in section II.A of the appendix.
