Danger Electrical Substation Sign – High Voltage Keep Out, 8x12 Rust-Resistant Aluminum Utility Power Warning Sign by CGAP Safety

Substations are not “electrical rooms with bigger boxes.” They are high-energy environments designed to move serious power, and they are not forgiving to curiosity, shortcuts, or accidental entry. When someone crosses a substation boundary, the risk profile changes immediately: shock exposure, arc-flash potential, and step-and-touch hazards become real, fast, and catastrophic.

The CGAP Safety “Danger – Electrical Substation – High Voltage – Keep Out” sign is built to establish a clear perimeter message at the exact places people make bad decisions: gates, fence lines, access points, equipment yards, and facility boundaries. The classic DANGER header forces attention, while the plain-language instruction removes ambiguity. It doesn’t debate. It doesn’t educate. It communicates the operational requirement: keep out.

This sign is a strong fit for utility substations, pad-mounted distribution areas, industrial power yards, municipal electrical infrastructure, large facility service entrances, and fenced equipment zones where unauthorized entry creates unacceptable risk and liability. It also works well for mixed-use properties where contractors, vendors, delivery drivers, and the public might be present and need an immediate “do not enter” cue without reading a paragraph of policy.

Manufactured in an 8 x 12 inch format from rust-resistant aluminum, it’s designed for long-term outdoor use on fences and gates, holding up against weather, heat, and day-to-day wear. The high-contrast red/black/white layout stays readable in the visual noise of industrial sites, which is where most “cheap sign solutions” go to die.

Use this sign as part of your access-control and hazard communication program to reduce unauthorized entry, support restricted-area enforcement, and signal high-voltage risk before someone gets close enough to learn the hard way.

CGAP Safety is an American safety manufacturer dedicated to straightforward, durable signage that helps organizations see the gap and close the gap between “we have rules” and “people follow them.”

Important: This product is a warning sign only and does not replace required training, fencing/security requirements, lockout/tagout procedures, PPE, or site-specific electrical safety policies. Always follow applicable standards and the facility’s written controls for restricted areas and high-voltage equipment.
