Saltwater Can Leave an Electrical Hazard Behind

Our electricians advise against reusing equipment exposed to seawater simply because it has dried. Salt residue remains conductive and highly corrosive long after the water recedes.

Immediate Threat: For fire, electrical shock, or an immediate hazard, move away to safety and call 911 immediately.
Saltwater Impact & Safety Protocol
⚠️ Coastal Flooding Assessment: After coastal flooding, a qualified electrician should evaluate affected outlets, breakers, and wiring to determine what components must be replaced.
⚠️ Surge Protection Limitations: Note that surge protection does not protect electrical equipment from floodwater damage.
✓ Pre-Storm Inspections: Before future severe weather, ask an electrician to check outdoor electrical equipment and existing wiring concerns while conditions are safe.
