1. Article 130, Work Involving Electrical Hazards, by definition, covers work involving four hazards caused by either proximity or equipment failure.

Explanation:
The main idea here is understanding which hazards NFPA 70E Article 130 actually defines for work involving electrical hazards. Article 130 identifies three distinct hazards: electric shock, arc flash, and arc blast. These hazards can arise from proximity to energized parts (shock and arc flash) or from arcing due to equipment failure (arc blast). Thermal effects from arc energy are a consequence often discussed with arc flash, but they are not listed as a separate fourth hazard within Article 130. So describing four hazards is not correct.
