Electrical hazards can be present in many working environments, including factories, warehouses, construction sites, workshops, plant rooms and commercial buildings.

Clear Electrical Hazard Signs help communicate risks associated with electrical installations, live equipment, cables and restricted electrical areas.

At The Sign Shed, we supply a wide range of Electrical Warning Signs, including high voltage notices, danger electricity signs, electric shock warnings, electrical cupboard signs and notices for overhead and underground cables.

Whether you're replacing a damaged warning sign, identifying an electrical cupboard or ordering signage for several business premises, our collection includes a choice of messages, sizes and materials.

High Voltage & Danger Electricity Signs

High voltage and electrical danger signs warn people about potentially dangerous electrical equipment and installations.

Common messages include:

• Danger High Voltage.
• Danger Electricity.
• Danger of Death.
• Risk of Electric Shock.
• Danger Live Electrical Equipment.

The appropriate warning depends on the electrical installation, its hazards and the people who may encounter it.

A general Danger Electricity Sign may be suitable in some locations, while a more specific warning may be appropriate elsewhere.

Electrical Cupboard & Switchgear Signs

Electrical cupboards, switchgear rooms and plant areas may require clear identification and warning notices.

Relevant signs can help communicate electrical hazards and restrictions around equipment.

Depending on the circumstances, suitable messages may include Electrical Cupboard, Danger Electricity, Keep Clear or Authorised Personnel Only.

The correct combination depends on the installation and applicable safety arrangements.

Overhead Electric Cable Warning Signs

Overhead electrical lines can create serious hazards where vehicles, machinery or equipment operate nearby.

Relevant signs include Danger Overhead Wires, High Voltage Cables Overhead and warnings aimed at drivers.

These notices may be appropriate at construction sites, industrial yards, agricultural premises and other locations where overhead electrical lines present a risk.

Warning signs should support appropriate clearances, work planning and other controls.

Underground & Buried Cable Signs

Underground electrical cables can present serious hazards during excavation and groundworks.

Signs such as Danger Buried Cable, Warning High Voltage Cables Underground and Caution Underground Services can help communicate known cable hazards.

However, warning signs are not a substitute for cable plans, suitable detection equipment, safe digging practices and other necessary precautions.

Electrical Isolation & Maintenance Signs

Some electrical notices communicate instructions rather than simply identifying a hazard.

Examples include:

• Do Not Switch On.
• Isolate Main Supply.
• Danger Live Electrical Equipment.
• Isolate for Safe Working.

These signs may be relevant to electrical maintenance activities and controlled working arrangements.

Temporary maintenance notices should be used as part of a suitable safe system of work. A sign alone does not electrically isolate equipment or prevent it being re-energised.

Electric Shock Warning Signs

Electric shock warning signs alert people to the risk of contact with dangerous electrical parts or equipment.

They may be appropriate at relevant electrical installations, test areas, switchgear or other locations where electrical hazards remain.

Choose wording and symbols that accurately reflect the risk.

Choosing Electrical Hazard Signs for Your Workplace

Before ordering, consider:

1. The specific electrical hazard.
2. Whether the sign is for equipment, a room, a cable route or a work area.
3. Whether a warning, prohibition or instruction is required.
4. Who needs to recognise the message.
5. The viewing distance and mounting position.
6. The sign material and environmental conditions.

For example, an electrical cupboard door may need a different warning from an outdoor location where vehicles could approach overhead power lines.

Self-Adhesive Electrical Signs or Rigid Signboards?

Self-adhesive vinyl signs can be practical for suitable smooth, clean surfaces, including electrical cupboards and equipment panels.

Rigid plastic signs may be preferable for walls, entrances and other locations requiring a mounted board.

Selected products are also available in recycled plastic, Foamex and aluminium composite.

Check individual product specifications for available materials, sizes and fixing options.

Where Should Electrical Hazard Signs Be Displayed?

Electrical warning signs should be positioned where people can recognise the relevant hazard before encountering it.

Potential locations include:

• Electrical cupboard doors.
• Switchgear and plant rooms.
• Relevant electrical equipment enclosures.
• Electrical testing areas.
• Construction site access points.
• Areas with overhead electrical cables.
• Suitable approaches to known underground cable hazards.

Signs should remain clearly visible and should not be hidden by open doors, equipment or stored materials.

Electrical Hazard Signs & UK Safety Regulations

The Electricity at Work Regulations 1989 establish requirements relating to electrical safety at work.

The Health and Safety (Safety Signs and Signals) Regulations 1996 require suitable workplace safety signs where significant risks remain after other relevant control measures have been taken.

BS EN ISO 7010 provides recognised graphical symbols for many safety signs, including the electrical hazard warning symbol.

However, buying or displaying a particular sign does not automatically establish compliance.

Electrical warning signs should support suitable risk assessments, competent working practices, safe isolation, access controls and other necessary precautions.
