Electrical Hazard Signs

Electrical Safety Signs help identify electrical hazards and warn people about potential dangers such as electric shock, high voltage equipment, live electrical systems and underground cables. They play a vital role in improving workplace safety and reducing the risk of accidents.

Also known as electrical warning signs, high voltage signs, electrical hazard signs and electricity danger signs, these signs are commonly used throughout industrial, commercial and public sector environments.

Electrical safety signs are widely used by facilities managers, electrical contractors, maintenance teams, construction companies, manufacturers, schools and local authorities. Common installation locations include substations, switch rooms, transformer compounds, distribution boards, plant rooms and restricted access areas.

Manufactured in the UK, our electrical safety signs are available in self-adhesive vinyl, rigid plastic, aluminium and photoluminescent glow in the dark materials to suit a wide range of indoor and outdoor applications.

Frequently Asked Questions

What are electrical safety signs?

Electrical safety signs warn people about electrical hazards including high voltage equipment, electric shock risks and live electrical systems.

Where should electrical safety signs be installed?

They should be displayed wherever electrical hazards exist, including switch rooms, substations, transformer compounds and electrical control panels.

What does a high voltage sign mean?

A high voltage sign warns that dangerous electrical voltages are present and that contact could result in serious injury or death.

Are electrical safety signs required in workplaces?

Electrical hazards should be clearly identified wherever risks remain and warning signage is necessary to communicate those dangers.

What colour are electrical warning signs?

Electrical warning signs typically feature a yellow background with black symbols and borders to indicate a potential hazard.

Can electrical safety signs be used outdoors?
