- 36. Electrical explosions directly into the face of a person working on or near energized electrical equipment can and will cause serious injury or death. OSHA laws and NFPA 70E have strict safety requirements for working on electrical equipment. The basic rules are to turn off the power before working on the equipment and to wear the proper type of nonflammable clothing. To further provide safety for the worker, the National Electrical Code has a requirement pertaining to arc-flash hazard warning. This requirement is found in a. 110.16 (A) b. 220.1 of the NEC C. 330.1 d. 410.5arrow_forward30.
