Danger Pad-Mount Transformer Sign – High Voltage Authorized Personnel Only, 8x12 Rust-Resistant Aluminum Electrical Utility Safety Sign by CGAP Safety

High-voltage equipment is not a “curious minds” situation. A pad-mount transformer can be present in plain sight on facility grounds, near parking areas, along walkways, or beside commercial buildings, and the risk is not theoretical. Unauthorized access can lead to severe shock, electrocution, and catastrophic injury.

The CGAP Safety “Danger – Pad-Mount Transformer – High Voltage – Authorized Personnel Only” sign is designed to deliver a clear, immediate message: this enclosure is energized equipment, and entry is restricted. The bold red DANGER header communicates the severity at a glance, while the restricted-access language helps deter tampering and supports controlled access policies for utility and facility operations.

This sign is sized at 8 x 12 inches for high visibility without being oversized, making it easy to place on fences, walls, posts, or near transformer pads in commercial, industrial, municipal, and utility-adjacent environments. The high-contrast red, black, and white OSHA-style layout is easy to read from a distance and helps cut through visual clutter on busy sites.

Manufactured from rust-resistant aluminum, this sign is built to hold up outdoors in sun, rain, and daily exposure better than paper notices and thin plastic signs that fade, crack, or peel.

Use this sign as part of your electrical safety, site security, and restricted-access program to help reduce unauthorized entry and reinforce hazard awareness around pad-mounted transformers.
