G'day! It’s a scenario that gives anyone the shivers: a buzzing power point, the smell of burning plastic from an appliance, or worse, seeing actual smoke coming from your switchboard. Electrical fires are a fair dinkum frightening prospect because you’re not just fighting flames; you're dealing with the added danger of live electricity.

Grabbing the wrong fire extinguisher in a panic can turn a bad situation into a catastrophic one. So, let’s get this sorted. Knowing exactly what fire extinguisher for electrical fires to use is one of the most important bits of safety knowledge you can have.

The Golden Rule: Don't Add Water to the Sparks

Before we even talk about what to use, let's cover what you must NEVER use. Do not, under any circumstances, use a water (solid red) or foam (red with a blue band) extinguisher on an electrical fire.

Water conducts electricity. Spraying water on a live electrical fire can create a direct path for the current to travel right back to you, leading to severe electrocution. It's an absolute no-go.

Understanding Fire Classes in Australia

To pick the right tool, you need to know what you're up against. In Australia, fires are categorised into classes. The one we're focused on is:

• Class E: Fires involving energised electrical equipment (e.g., appliances, switchboards, power boards, wiring).

The "E" tells you that there's an electrical risk, and you need an extinguisher with non-conductive properties.

The Right Tools for the Job: Your Go-To Extinguishers

For a Class E electrical fire, you have two primary, safe choices. You can identify them by the coloured band on the cylinder.

1. Carbon Dioxide (CO2) Extinguisher – The Black Band

This is the top-shelf choice for electrical fires, especially around sensitive and expensive electronics like computers, TVs, or sound systems.

• How it works: CO2 gas smothers the fire by displacing oxygen. It also comes out freezing cold, which helps to cool the fuel source.
• Pros: It’s incredibly effective and, best of all, it’s a clean agent. It leaves behind no residue, meaning it won’t destroy the equipment you’re trying to save.
• Cons: It has a short, powerful range, so you need to be reasonably close. It also displaces oxygen in the air, so you must ensure the area is well-ventilated after use.

2. Dry Chemical Powder (ABE) Extinguisher – The White Band

This is the most common and versatile extinguisher you’ll find in homes, cars, and workplaces. It’s a great all-rounder.

• How it works: It shoots a fine powder that interrupts the chemical reaction of the fire.
• Pros: It's rated for Class A (wood/paper), Class B (flammable liquids), and Class E fires, making it incredibly versatile. If you're only going to have one extinguisher in the garage or kitchen, this is often the one.
• Cons: It works, but it makes a massive mess. The fine powder gets everywhere and can be corrosive, potentially causing permanent damage to the delicate parts of any electronics it touches.

Before You Fight Any Fire: Your Safety Checklist

Knowing which extinguisher to use is only half the battle. If you're faced with an electrical fire, your personal safety is paramount.

1. Kill the Power: If it is safe to do so, turn off the electricity at the main switchboard. This removes the "E" from the fire, turning it into a regular Class A fire, which is much less hazardous to fight.
2. Call Triple Zero (000): Do this before anything else. Fire services should always be on their way, even if you think you can handle it.
3. Assess the Situation: Only attempt to fight a fire if it is small (like the size of a small waste bin), contained, and you have a clear, safe escape route behind you. If the room is filling with smoke, get out, stay out, and close the door behind you.
