No Swimming Shock Hazard Compliance Sign

NEC 555.24 & NFPA 303 Compliant

A new requirement added to the 2017 National Electrical Code (NEC) Section 555.24 mandates the posting of warning signage at marinas and boatyards to alert personnel and the public of potential electrical shock hazards in and around the water. This requirement was established in response to numerous documented cases of Electric Shock Drowning (ESD) and serious injuries at marina and boatyard facilities.

This high-visibility warning sign helps marina and boatyard operators meet NEC and NFPA safety obligations by clearly communicating the danger of electrical currents in the water to anyone approaching the facility.

Required Warning Message

The sign states exactly as required by NEC 555.24 and 110.21(B)(1):

“WARNING — POTENTIAL SHOCK HAZARD — ELECTRICAL CURRENTS MAY BE PRESENT IN THE WATER.”

The signage must be clearly visible from all approaches to the marina or boatyard and serves as a critical safety measure for the general public, who may not understand the electrical dangers present in these environments.
