Which hazard is most closely associated with moisture near electrical equipment?

• A. Frayed cords
• B. Water near equipment
• C. Open panels
• D. Grounded plugs

Answer: (B)

Moisture near electrical equipment creates a conductive path that can carry current where it shouldn’t flow. Water lowers insulation resistance and can bridge gaps between live parts and grounded or exposed surfaces. That makes electric shock, arc flash, short circuits, and even fires much more likely. Keeping equipment dry and properly enclosed reduces these risks, which is why the hazard described as water near equipment is the closest match to moisture-related danger. Frayed cords, open panels, and grounded plugs are separate hazards—damaged insulation, exposed energized parts, and proper grounding—so they’re not the moisture-focused risk in this scenario.
