Which hazard should be avoided during electrical maintenance?

• A. Energized components
• B. Water exposure
• C. Electrical noise
• D. Ground faults

Answer: (B)

Water exposure should be avoided because moisture makes electrical work far more dangerous. Water conducts electricity, so even a small amount can create a path from live parts to metal surfaces or to ground. That increases the likelihood of electric shock, short circuits, or an arc flash, and it can damage insulation over time. In HVAC maintenance, condensate, rain, leaks, or wet surfaces are common, so the area and equipment must be dry and de-energized before touching components. Use dry hands and insulating tools, and keep the work area free of standing water to reduce these risks.
