DANGER Lithium-Ion Energy Storage System (ESS) Sign – 8x12 Aluminum

Battery energy storage systems (ESS) are being installed in more buildings, solar projects, and microgrids every year. When large banks of lithium-ion batteries are concentrated in one room or container, fire behavior is very different than a typical electrical room. This CGAP Safety DANGER sign gives you a clear way to mark those spaces as “LITHIUM-ION ENERGY STORAGE SYSTEM – FIRE, EXPLOSION, AND TOXIC GAS HAZARD – EMERGENCY RESPONDERS: CHECK ESS DATA LABEL.”

Printed on 8x12 inch .040 aluminum, the sign is rigid, rust-proof, and suitable for long-term use inside or on the exterior of ESS rooms, battery containers, and fenced compounds. The bold red DANGER header and simple language stand out to electricians, technicians, and fire crews, helping them quickly identify that they are dealing with a battery storage hazard.
