Electric Hazard Signs – New Zealand’s Specialists
Electricity is a powerful and essential part of modern workplaces, infrastructure, and public environments — but it also presents serious risks when not clearly identified and controlled. Electric Hazard Signs play a critical role in warning people of electrical danger, preventing accidental contact, and supporting compliance with New Zealand health and safety obligations.
At Emmjay Safety Sign Factory, we supply New Zealand’s largest online range of electric hazard signs, designed for industrial sites, construction zones, commercial buildings, utilities, plant rooms, switchboards, and public access areas. From high-voltage warning signs and “Danger – Live Electrical Equipment” signage to general electrical hazard notices, our signs are built for visibility, durability, and long-term outdoor performance.
As New Zealand specialists in large safety signage, we also offer all electric hazard sign options in high-tack self-adhesive vinyl, making it easy to apply clear warnings to switchboards, cabinets, enclosures, walls, and machinery.
Why Electric Hazard Signs Are Essential
Electric hazard signs are not optional extras — they are a core part of risk management and legal compliance.
Key reasons electrical hazard signage matters:
- Life safety – Electricity can cause severe injury or death through electric shock, burns, arc flash, or fire. Clear signage warns people before they enter a danger zone.
- Legal compliance – New Zealand health and safety legislation requires duty holders to identify hazards and take reasonably practicable steps to warn and protect people.
- Restricted access control – Signs clearly communicate “authorised personnel only” areas around live equipment.
- Reduced liability – Proper signage demonstrates proactive hazard management and supports your safety systems.
- Professional site standards – Well-designed signage reinforces a strong safety culture and professional presentation.
Whether the risk is high voltage, live electrical equipment, underground cables, or electrical panels, the right sign helps prevent accidents before they occur.
Where Electric Hazard Signs Are Commonly Used
Electric hazard signs are essential across a wide range of environments, including:
- Industrial facilities & factories – Switch rooms, control panels, substations, plant equipment.
- Construction sites – Temporary and permanent electrical installations, generators, distribution boards.
- Commercial buildings – Electrical cupboards, lift motor rooms, service risers.
- Utilities & infrastructure – Power substations, transformers, electrical enclosures, roadside cabinets.
- Schools, hospitals & public buildings – Restricted plant rooms and electrical service areas.
- Warehouses & logistics sites – High-voltage equipment, charging stations, automated systems.
- Outdoor & remote installations – Solar arrays, wind systems, electrical fencing controllers.
Clear electric hazard signs ensure that staff, contractors, and visitors understand the risk before entering or interacting with electrical equipment.
