Danger 400 Electrical Volts Signs help you warn staff, contractors and visitors before they approach 400V equipment in plant rooms, workshops and service areas.
Danger 400 Electrical Volts Signs warn you, your staff and contractors before they approach 400V electrical equipment. Use them on plant rooms, machinery doors and service cupboards where a clear W012 electrical shock warning helps prevent unsafe access.
Where Danger 400 Electrical Volts Signs Should Be Positioned
You should install these signs at the point someone first reaches the 400V hazard: plant-room doors, switchgear access, machine isolator covers and electrical cupboards. Place them before hands reach live equipment, not after the risk has already been entered.
Practical Viewing Distance for 400V Warnings
For a 100 x 250 mm landscape sign, use close-range placement where people read the warning at the door, enclosure or control point. Aim for roughly 1–3 metres of clear approach visibility, with larger signs used if the first decision point is further away.
What Should Improve Once the 400V Warning Is Displayed
After installation, the sign changes behaviour at the decision point: people slow down, recognise the 400V shock risk and avoid opening, touching or entering electrical areas without authority or isolation.
✅ Fewer unauthorised approaches to live 400V equipment
✅ Clearer hazard recognition for contractors and maintenance teams
✅ Stronger control before panels, cupboards or plant rooms are opened

Installing Danger 400V Electrical Warnings Without Weak Placement
Common placement mistakes
❌ Fitting the sign inside the electrical area instead of before entry
❌ Placing it too low, behind handles or beside cluttered equipment
❌ Using one sign where several approach points need separate warnings
When this sign is not enough
❌ Do not rely on it as a substitute for isolation procedures
❌ Do not use it where a more specific lock-off warning is required
❌ Do not fit vinyl to dusty, wet or uneven surfaces without preparation
Better installation choices
✅ Clean and dry the surface before applying self-adhesive vinyl
✅ Put the warning at eye level near the first touch or entry point
✅ Use rigid plastic where the sign needs a more durable fixed position
Danger 400 Electrical Volts Signs questions answered
Where should I use Danger 400 Volts signs? Use them where someone could approach, open or work near 400V electrical equipment, including plant rooms, machinery access points, control cabinets and service cupboards.
Should I choose rigid plastic or self-adhesive vinyl? Choose vinyl for clean, smooth doors or equipment surfaces. Choose rigid plastic where the sign needs a stronger mounted finish or may be removed during maintenance.
Is W012 the correct symbol for this type of electrical warning? Yes. W012 is the EN ISO 7010 warning symbol used for electricity hazards, helping people recognise electrical shock risk quickly.
Who needs to see this sign? It helps staff, contractors, engineers, cleaners and visitors understand that the area contains a 400V electrical hazard before they touch or open anything.
Are these signs suitable outside? They can be used indoors or outdoors, but you should choose the material and fixing method based on exposure, surface condition and how long the sign needs to remain in place.
