Danger high voltage sign or label

A danger high voltage sign and a danger high voltage label carry the same ANSI Z535.4 message. The difference is the substrate. A sign is usually a rigid panel mounted to a fence, gate or wall, and a label is an adhesive film applied directly to the enclosure, cabinet door or transformer housing it is warning about.

For panels, disconnects, machine cabinets and switchgear, the adhesive label is what you want, since it stays with the equipment and cannot be unbolted or swapped by mistake. We print them on 3.0 mil industrial vinyl with a UV stable overlaminate rated 5+ years outdoors.

Label the enclosure, mark the voltage

A generic high voltage label tells someone to stop. A voltage marked label tells them what they are about to be exposed to and what PPE the job calls for. On mixed systems, marking each enclosure with its actual voltage prevents the wrong assumption at the worst moment.

These are equipment labels sized for panel doors, disconnect covers and machine cabinets. For large rigid room signs, contact us for a quote.

Durability that matches the environment

Paper labels and consumer sticker stock chalk, curl and fade within a season in a plant or outdoors. Our labels use the same laminated industrial vinyl as our arc flash labels, so the header stays red and the copy stays readable through washdown, UV and temperature swings.

Frequently asked questions

What voltage counts as high voltage for labeling?

There is no single number for label wording. Many facilities apply a high voltage label above 600V and mark the exact operating voltage below that. The safe practice is marking the actual voltage on the enclosure regardless of the threshold used.

Do you make these in other sizes?

The stock printed label is 6" x 4". We can quote other printed sizes, and engraved nameplate products are produced up to 4" wide.

Are these OSHA compliant?

They use the ANSI Z535.4 signal word format that OSHA 1910.145 and 1910.303 accept for hazard marking, and they are durable enough for the environment as required by 1910.303(e).

Can I order just one?

Yes. There is no minimum and no setup fee on premade designs.
