Danger Electrical Room Sign – High Voltage, 8x12 Rust-Resistant Aluminum Safety Sign for Utility, Maintenance, Industrial Facilities, Mechanical/Electrical Rooms by CGAP Safety

Electrical rooms are not “storage rooms with a different label.” They frequently contain energized equipment, high-voltage distribution components, panels, disconnects, switchgear, and other infrastructure that can cause serious injury or death if accessed by unqualified personnel or approached casually.

The CGAP Safety DANGER – Electrical Room – High Voltage sign is a direct, high-visibility warning intended to set expectations immediately at the point of entry. In many facilities, the most common failure mode is not a technical mistake. It is someone entering the wrong door, assuming the area is safe, or treating electrical infrastructure like standard building utility space. This sign helps prevent that predictable human behavior from turning into a preventable incident.

This format is especially useful in mixed-use buildings where electrical rooms sit near offices, hallways, break areas, or storage zones and the door looks like every other door. By clearly calling out ELECTRICAL ROOM and HIGH VOLTAGE, the sign reinforces restricted-area awareness for employees, vendors, contractors, inspectors, and anyone moving through the facility.

Manufactured in an 8 x 12 inch size, the layout is designed to be read quickly without needing to walk up and stare at it like it’s a museum placard. The sign is produced from rust-resistant aluminum for long service life in industrial and commercial environments where humidity, cleaning, and daily traffic destroy lesser materials.

Important: This sign supports hazard communication and access control awareness. It does not replace qualified electrical safety practices, lockout/tagout procedures, PPE requirements, or site-specific safety policies.

1. ELECTRICAL ROOM DANGER SIGN – Clear, high-visibility message warns personnel that the space is an electrical room and that high voltage may be present behind the door or within the area.
2. REDUCES UNAUTHORIZED ACCESS & “ACCIDENTAL ENTRY” – Helps deter casual entry by visitors, new employees, contractors, and anyone not qualified to be inside energized or restricted electrical spaces.
3. BUILT FOR FACILITIES THAT CAN’T AFFORD INCIDENTS – Ideal for commercial buildings, factories, warehouses, data closets, pump stations, utility corridors, maintenance areas, and mechanical/electrical rooms.
4. FAST-READ LAYOUT FOR REAL-WORLD CONDITIONS – Large block lettering is designed to be understood quickly from a distance, in low-light hallways, noisy plants, and active work zones.
5. 8x12 RUST-RESISTANT ALUMINUM – Manufactured from rust-resistant aluminum for long-term indoor/outdoor use, holding up better than paper notices or thin plastic in high-traffic facilities.
6. MADE BY AN AMERICAN SAFETY MANUFACTURER – Produced by CGAP Safety, an American safety sign manufacturer focused on durable materials and straightforward safety messaging.
