Which of the following is a common electrical hazard?

• A. Arc flash/arc blast hazards
• B. Oxygen deficiency
• C. Chemical reactivity
• D. Rollover hazard

Answer: (A)

Electrical work carries the risk of arc flash and arc blast, which are sudden releases of energy when a fault causes current to jump between conductors or to ground. An arc flash creates intense heat, bright light, pressure waves, and possibly flying debris, all of which can cause severe burns, eye injuries, and hearing damage. This hazard is central to electrical safety and is mitigated through proper energy isolation, arc-rated PPE, face shields, insulated tools, and maintaining safe distances, guided by standards like NFPA 70E that help determine incident energy and protective equipment needs.

Oxygen deficiency is a hazard tied to confined spaces and ventilation, not the electrical energy itself. Chemical reactivity concerns substances that can react violently, which is chemical safety rather than an electrical hazard. Rollover hazards involve vehicle or equipment tipping and are unrelated to electrical energy.

So, arc flash/arc blast hazards are the common electrical hazard.
