French "Warning High Voltage" sign

The EOS506 French "Avertissement Haute tension" sign identifies an electrical area, technical room, panel, cabinet or equipment where high voltage may be present. It suits workshops, electrical rooms, mechanical rooms, control cabinets, distribution panels, maintenance access points and sectors where a visual instruction helps prevent unauthorized entry or intervention. Its message helps employees, visitors, contractors and technicians quickly recognize a potential electrical hazard. This sign supports prevention and visual organization without replacing internal procedures, lockout, work permits, training, supervision, required protective equipment or other applicable controls.

Several materials, sizes and formats are available from the drop-down menu.

UV-protecting lamination, retro-reflective sheeting or photoluminescent finishing can also be requested depending on the need. Please contact customer service for sign formats other than those offered in the options above, as well as for English or bilingual signs. Please allow four (4) weeks to receive special orders.

Applications for the EOS506 electrical area sign

The EOS506 sign can be installed at the entrance to an electrical room, on a technical door, near a control cabinet, close to a distribution panel or in a maintenance zone where high voltage may be present. It helps remind users that access and intervention must follow site instructions and be reserved for authorized or qualified people.

Material choice for a High Voltage sign

Choosing a sign depends on the right material, reading distance, work environment and required format. Self-adhesive vinyl is suited to clean, smooth and dry surfaces, especially indoors or in a protected location. Plastic can be used indoors or outdoors, but colours may fade faster if the sign is exposed to UV light. Aluminum is often recommended outdoors, at entrances, in workshops, docks and areas where impact is possible. UV-protecting lamination may slow fading, without preventing it permanently.
