Flood Electrical Safety

DID YOU KNOW?

From 2003 to 2012, the U.S. National Flood Insurance Program processed more than $3.6 billion in claims — and many involved electrical system damage or fire risk after flooding. [1] Floodwaters don’t just ruin belongings — they turn your home into a serious shock hazard.

KNOW THE RISK

  • More deaths occur annually from flooding than any other weather-related cause. [1]
  • Floodwater can energize outlets, appliances, and even structural materials, creating an invisible electrocution hazard. [1]
  • Even after floodwaters recede, residual moisture can lead to short circuits, arcing, or electrical fires if systems are re-energized too soon. [1]

MITIGATE THE RISK

1. Shut Off Power Before the Flood Hits

  • Follow official instructions to turn off utilities in advance of a flood. If you must shut off power, flip all individual breakers off before turning off the main breaker. [1]

2. Avoid Submerged Equipment

  • Never enter a flooded area where electrical equipment is or may be submerged. Wait until a licensed electrician confirms it is safe. [1]

3. Keep the Power Off After Flooding

  • After a flood, do not attempt to turn power back on yourself. Contact a qualified professional to inspect and clear the system first. [1]

4. Replace Water-Damaged Components

  • Outlets, switches, breaker panels, and appliances exposed to floodwater may need to be replaced, even if they appear undamaged. Moisture and silt can compromise safety. [1]

ELECTRICAL SAFETY REMINDER

Floods are dangerous — and the risks don’t end when the water disappears. Electrical systems exposed to water must be treated as hazardous until inspected. When in doubt, stay out, and call a professional.
