Know how to safely disconnect power if necessary
Property owners should know where their main electrical disconnect is and should never operate damaged or flooded electrical equipment.
Protect sensitive electronics appropriately
Surge protection strategies can help reduce exposure to some electrical transients, although no device can guarantee protection from every lightning or utility event.
Do not use generators indoors
Portable generators produce deadly carbon monoxide. They must be operated outdoors in accordance with manufacturer instructions and local requirements, away from doors, windows and openings.
Never backfeed a home through a receptacle
Improvised generator connections can create electrocution and fire hazards. Generator connections should use properly designed transfer equipment and compliant installation methods.
After flooding, wait for professional evaluation
Electrical equipment exposed to water may be unsafe even if it appears dry. Do not energize affected systems until they have been appropriately evaluated.
Plan electrical improvements before a storm is approaching
Major electrical work, repairs and permit-dependent improvements are easier to manage before a weather emergency is imminent.
