NFPA 70E Annex Simplified Approach
H.1 Use of Simplified Approach. The use of Table H.1 is suggested as a simplified approach to provide minimum personal protective equipment for electrical workers within facilities with large and diverse electrical systems. The clothing listed in Table H.1 fulfills the minimum FR clothing requirements of Table 130.7(C)(9) and Table 130.7(C)(10). The clothing systems listed in this table should be used with the other PPE appropriate for the Hazard/Risk Category. [See Table 130.7(C) (10).] The notes at the bottom of Table 130.7(C) (9) must apply as shown in that table.

For tasks not listed or for power systems with greater than the assumed short-circuit capacity or with longer than the assumed fault clearing times, an arc flash hazard analysis is required in accordance with 130.3.
