Electrical Fire: How to Put It Out Safely (Without Water!)

The Most Important Rule: NEVER Use Water

Water conducts electricity. If you throw water on an electrical fire, you risk electrocution and can actually spread the fire. This is the single most important rule to remember: never use water on an electrical fire.

Electrical fires occur when electrical current ignites surrounding materials like insulation, wood, or fabric. They can start in outlets, appliances, wiring, or your electrical panel. Knowing how to respond quickly and correctly can save lives and prevent extensive damage.

Step 1: Cut the Power

If you can safely reach your electrical panel without passing through flames or smoke, turn off the power to the affected area. If the fire is in an outlet or appliance, flip the corresponding breaker. If you're unsure which breaker controls the area, or if the fire is in the panel itself, turn off the main breaker.

Cutting the power eliminates the electrical source of the fire, making it safer to extinguish. However, remember that wires can still hold residual charge, and the fire may have already spread to non-electrical materials.

Step 2: Use the Right Fire Extinguisher

For electrical fires, you need a Class C fire extinguisher (in the US) or a fire extinguisher rated for electrical fires. Look for extinguishers labeled with a "C" symbol or specifically marked for electrical use.

Many modern fire extinguishers are rated ABC, meaning they work on Class A (ordinary combustibles), Class B (flammable liquids), and Class C (electrical) fires. If you have an ABC extinguisher, it's suitable for electrical fires.

How to Use a Fire Extinguisher (PASS Method)

1. Pull the pin at the top of the extinguisher
2. Aim the nozzle at the base of the fire, not the flames
3. Squeeze the handle to release the extinguishing agent
4. Sweep the nozzle from side to side until the fire is out

Step 3: Use Baking Soda for Small Fires

For very small electrical fires—like a small flame coming from an outlet—you can use baking soda as an alternative if you don't have a fire extinguisher. Baking soda is sodium bicarbonate, which is the same chemical found in many fire extinguishers.

Simply pour baking soda over the base of the fire. This works best on small fires in confined areas. It won't be effective on larger fires or those that have spread beyond the electrical source.

Note: Do NOT use flour, sugar, or other baking powders—these can actually fuel the fire.

Step 4: Use a Fire Blanket

A fire blanket is a safety device designed to extinguish small fires by smothering them. If you have a fire blanket, carefully place it over the fire to cut off oxygen. This is particularly useful for small appliance fires or fires in tight spaces.

Fire blankets are made of fire-resistant materials and can withstand high temperatures. They're a good addition to any home safety kit.

What NOT to Do

• NEVER use water: Water conducts electricity and can cause electrocution
• Don't use a Class A extinguisher only: These are designed for wood, paper, and fabric fires, not electrical
• Don't fan the fire: This adds oxygen and can make the fire spread
• Don't try to move burning appliances: You risk spreading the fire and getting burned
• Don't re-energize the circuit: After extinguishing the fire, leave the power off until inspected by an electrician

When to Call 911

Call 911 immediately if:

• The fire is larger than a small trash can
• The fire is spreading to walls, curtains, or other materials
• You can't safely reach the electrical panel
• You don't have the right fire extinguisher
• Smoke is filling the room
• Anyone is in danger or injured

After the Fire: What to Do Next

1. Keep the power off: Don't turn the breaker back on until an electrician has inspected the damage
2. Document the damage: Take photos for insurance purposes
3. Contact your insurance company: Report the fire and start the claims process
4. Call a licensed electrician: Electrical fires can cause hidden damage to wiring that isn't immediately visible
5. Have the system inspected: Before restoring power, have a professional assess the entire electrical system

Preventing Electrical Fires

The best way to handle an electrical fire is to prevent it from happening in the first place:

• Don't overload outlets: Avoid using multiple high-draw appliances on the same circuit
• Replace damaged cords: Frayed or damaged cords are a major fire hazard
• Use surge protectors: Protect sensitive electronics from power surges
• Install AFCI breakers: Arc-fault circuit interrupters detect dangerous arcing and prevent fires
• Schedule regular inspections: Have a licensed electrician inspect your electrical system every 5-10 years
• Upgrade old wiring: Knob-and-tube and aluminum wiring pose significant fire risks
• Install smoke detectors: Working smoke detectors provide early warning of any fire

Warning Signs of Electrical Problems

Watch for these warning signs that could indicate an increased fire risk:

• Frequently tripping breakers
• Flickering or dimming lights
• Buzzing sounds from outlets or switches
• Burning smell near outlets or the panel
• Warm or hot outlets and switches
• Scorch marks around outlets
• Sparking when plugging in devices

If you notice any of these signs, call a licensed electrician immediately. These are warning signs that should never be ignored.
