What to Do in an Electrical Fire? A Quick NZ Safety Guide

What to Do in an Electrical Fire? A Quick NZ Safety Guide

Electrical fires can start fast often from damaged electrical wires, overloaded circuits, or faulty appliances. Knowing what to do in an electrical fire helps you act safely and protect your property.

At Grammar Electrical, safety is at the core of everything we do. Here’s a simple guide on what to do for an electrical fire. It covers how to handle it and how to prevent electrical hazards before they start.

Step 1: Turn Off the Power (if it’s safe)

If you see smoke or sparks, switch off power at the main breaker immediately. This cuts electricity to the source and stops the fire from spreading.

Never touch live electrical wires or burning outlets. Only turn off the main switchboard if you can do so without danger.

Step 2: Never Throw Water on an Electrical Fire

Many people make the mistake of throwing water on an electrical fire, but that’s extremely dangerous. Water conducts electricity and can cause serious electric shock.

Instead, use a Class C dry-powder or CO₂ fire extinguisher designed for electrical fires. Aim at the base of the flames and spray in short bursts.

If the fire spreads or fills the room with smoke, evacuate immediately and call 111 for the fire service.

Step 3: Unplug Appliances (if possible)

Once power is off, carefully unplug nearby electrical appliances to eliminate further ignition sources. If cords are melted or sparking, stay back and wait for firefighters.

Step 4: Call the Fire Service and an Electrician

Even if the flames seem out, always contact the fire service. Electrical fires can smoulder inside walls and reignite later.

After the event of a fire, call Grammar Electrical. Our licensed electricians will inspect your system, check for damaged electrical wires, and repair or replace anything unsafe.

Common Causes of Electrical Fires

Understanding the causes helps you prevent electrical hazards:

  • Frayed or overloaded electrical wires
  • Faulty outlets or switchboards
  • Outdated circuit breakers
  • Moisture or dust inside sockets
  • Overused extension cords
  • Flickering lights and power surges


If you notice constant flickering lights, a burning smell, or warm outlets, switch off power and call an electrician immediately.

How to Prevent Electrical Fires

Prevention is always better than reaction. Simple steps can drastically lower your risk:

  • Avoid overloading outlets or power boards
  • Replace damaged plugs and electrical wires
  • Unplug appliances not in use
  • Schedule professional inspections every 2-3 years
  • Install smoke alarms and test them monthly
  • Keep a Class C extinguisher near kitchens or switchboards


Routine electrical maintenance by Grammar Electrical helps identify hidden issues and prevent electrical fires before they start.

Once it’s safe:

  1. Keep the power off until an electrician inspects it.
  2. Report damage to your insurer.
  3. Replace burnt outlets and electrical wires.
