High Voltage Keep Clear Danger Sign

Description

Electrical hazards don’t announce themselves — a live panel looks exactly like a dead one. That’s why OSHA expects high-voltage areas to be clearly marked, and why this sign belongs on every electrical room door, temporary power setup, transformer enclosure, and distribution panel on your site. The red oval DANGER header and bold KEEP CLEAR message are the recognized format, and posting it is one of the first things a safety walk-through checks.

Each sign is printed at our NYC facility in three sizes — 12″ × 18″ for doors and panels, 18″ × 24″ and 24″ × 36″ for enclosures and standoff distances — on aluminum in 0.40, 0.63, or 0.80 gauge, or 0.60 styrene. The print is UV- and weather-resistant, so a sign mounted on an outdoor transformer fence holds its color and legibility year after year.

Ordering is straightforward: pick your size and material, and the sign ships ready to screw or zip-tie in place. Delivery across the five boroughs and Long Island runs 2–3 business days, with 24-hour rush available on most orders — useful when an electrical inspection is on the calendar and the posting isn’t.

Electricians and GCs running multiple jobs can set up a contractor account for volume pricing and fast re-orders. If your site also has restricted mechanical or utility spaces, our Authorized Personnel Only Danger Sign covers the doors this one doesn’t.

FAQ

Where should high voltage signs be posted on a job site?
Post them at every point of access to energized equipment — electrical room doors, panel covers, temporary power distribution, and transformer or switchgear enclosures.

Is this sign suitable for permanent building use after construction?
Yes — the heavier aluminum gauges are built for permanent installation, and the OSHA danger format is the standard for marking electrical hazards in occupied buildings.
