What To Do In An Electrical Fire

Electrical fires are a terrifying prospect, capable of causing extensive damage and posing significant risks to life. Knowing how to react swiftly and correctly is paramount in mitigating the danger. This comprehensive guide outlines the critical steps to take in the event of an electrical fire, emphasizing safety and preparedness.

Understanding the Nature of Electrical Fires

Electrical fires differ from typical fires due to the presence of energized electrical components. Water, a common fire extinguishing agent, becomes a conductor of electricity, escalating the risk of electrocution. Consequently, specific protocols must be followed to safely manage these incidents.

Common Causes of Electrical Fires:

Faulty Wiring: Deteriorated, damaged, or improperly installed wiring is a primary culprit.
Overloaded Circuits: Plugging too many devices into a single circuit can exceed its capacity, leading to overheating and fires.
Damaged Appliances: Malfunctioning or poorly maintained appliances can spark electrical fires.
Loose Connections: Loose wiring connections create resistance, generating heat and potential ignition points.
Extension Cord Misuse: Overloading extension cords or using them for permanent wiring is a fire hazard.

Immediate Actions: Prioritizing Safety

The first moments after discovering an electrical fire are critical. Your immediate actions can significantly impact the outcome.

Assess the Situation: Before anything else, quickly evaluate the size and nature of the fire. Is it small and contained, or is it rapidly spreading? Are there immediate threats to life?
Evacuate Immediately if Necessary: If the fire is large, spreading quickly, or you feel unsafe, evacuate the premises immediately. Do not hesitate. Your safety is the top priority. Alert others in the building as you leave.
Call Emergency Services: Once you are in a safe location, call the fire department or emergency services immediately. Provide them with accurate information about the fire's location and nature.
Cut Off the Power (If Safe): If you can safely access the main electrical panel and the fire is small and contained, turn off the power to the affected circuit or the entire building. This will eliminate the source of the fire and reduce the risk of electrocution. Important: Only attempt this if you are absolutely sure it is safe to do so. If there is any water present, or if you are unsure, do not approach the electrical panel.
Use the Correct Fire Extinguisher: If the fire is small and you have a fire extinguisher rated for electrical fires (Class C), you can attempt to extinguish it. Remember the PASS acronym:
- Pull the pin.
- Aim at the base of the fire.
- Squeeze the handle.
- Sweep from side to side.
Important: Never use water on an electrical fire. Only use a fire extinguisher specifically designed for electrical fires. If you are unsure about using the fire extinguisher, evacuate and wait for the fire department.

Detailed Steps to Take During an Electrical Fire

Let's break down the actions you need to take in more detail:

1. Evaluating the Situation: A Quick and Critical Assessment

The initial assessment is crucial. Don't rush into action blindly. Take a moment to observe the fire and its surroundings.

Size and Scope: Is it a small fire contained within an appliance, or is it spreading to walls and other materials?
Smoke Levels: Is there heavy smoke? Smoke inhalation is a major hazard in fires.
Escape Routes: Identify clear and safe escape routes. Ensure they are not blocked by fire or debris.
Potential Hazards: Are there flammable materials nearby that could accelerate the fire? Are there any signs of structural damage?

2. Evacuation Protocol: Getting Out Safely

If the situation warrants it, immediate evacuation is non-negotiable.

Prioritize People: Ensure everyone in the building is alerted and evacuates safely.
Stay Low to the Ground: Smoke rises, so stay low to the ground to avoid inhaling toxic fumes.
Feel Doors Before Opening: Before opening a door, feel it with the back of your hand. If it is hot, do not open it. The fire may be on the other side.
Close Doors Behind You: As you evacuate, close doors behind you to help contain the fire and slow its spread.
Designated Meeting Point: Establish a designated meeting point outside the building where everyone can gather to ensure everyone is accounted for.
Do Not Re-enter: Never re-enter a burning building for any reason. Wait for the fire department to give the all-clear.

3. Calling Emergency Services: Providing Accurate Information

When calling emergency services, provide them with the following information:

Your Location: Give the exact address of the fire.

Size and Scope: Describe the size of the fire and whether it is spreading.
Injuries: Report any injuries or people trapped inside the building.
Your Name and Phone Number: Provide your name and phone number so the dispatcher can contact you for further information.

4. Cutting Off the Power: A Delicate Maneuver

Only attempt to cut off the power if it is safe to do so and you are comfortable with electrical panels.

Locate the Main Electrical Panel: This is usually located in the basement, garage, or utility room.
Dry Hands: Ensure your hands are completely dry before touching the electrical panel.
Stand on a Dry Surface: Stand on a dry surface to avoid becoming a ground.
Flip the Main Breaker: Flip the main breaker switch to the "off" position. This will cut off power to the entire building.

Warning: If there is any sign of water near the electrical panel, do not approach it. Call the fire department and let them handle it.

5. Using a Fire Extinguisher: The Right Tool for the Job

Using the wrong type of fire extinguisher can be dangerous and ineffective.

Class C Fire Extinguisher: This type of fire extinguisher is specifically designed for electrical fires. It contains a non-conductive extinguishing agent that will not conduct electricity.
Read the Instructions: Before using the fire extinguisher, read the instructions carefully.
Maintain a Safe Distance: Stand at a safe distance from the fire.
Aim at the Base of the Fire: Aim the nozzle of the fire extinguisher at the base of the fire, not the flames.
Sweep from Side to Side: Sweep the fire extinguisher from side to side, covering the entire area of the fire.
Discharge Completely: Discharge the entire contents of the fire extinguisher to ensure the fire is completely extinguished.

Important: Even if you successfully extinguish the fire, call the fire department to inspect the area and ensure there are no hidden embers or potential for reignition.

What NOT to Do During an Electrical Fire

Knowing what not to do is just as important as knowing what to do. Here's a list of critical DON'Ts:

Do not use water: This is the most important rule. Water conducts electricity and can cause electrocution.
Do not use a Class A or Class B fire extinguisher: These types of fire extinguishers are designed for ordinary combustibles and flammable liquids, respectively. They are not suitable for electrical fires.
Do not approach the fire if you feel unsafe: Your safety is the top priority. If you are unsure about whether it is safe to approach the fire, evacuate and wait for the fire department.
Do not touch anyone who is in contact with electricity: If someone is being electrocuted, do not touch them. You could become a victim yourself. Use a non-conductive object, such as a wooden broom handle, to separate them from the electrical source.
Do not re-enter the building until it is declared safe: Even after the fire is extinguished, there may be hidden dangers, such as structural damage or toxic fumes. Wait for the fire department to give the all-clear before re-entering the building.

The Science Behind Electrical Fires

Understanding the scientific principles behind electrical fires can help you better appreciate the dangers and the importance of taking appropriate precautions.

Joule Heating: When electricity flows through a conductor, it generates heat. This is known as Joule heating. If the conductor is too small or the current is too high, the conductor can overheat and ignite nearby flammable materials.
Arc Faults: An arc fault is an unintentional electrical discharge between two or more conductors. Arc faults can generate extremely high temperatures, which can easily ignite nearby flammable materials.
Insulation Breakdown: The insulation on electrical wiring is designed to prevent electricity from escaping the conductors. However, over time, the insulation can break down due to heat, age, or physical damage. When the insulation breaks down, electricity can leak out and cause a fire.

Psychological Impact of Electrical Fires

Experiencing an electrical fire can be a traumatic event that can have lasting psychological effects.

Post-Traumatic Stress Disorder (PTSD): Some people may develop PTSD after experiencing an electrical fire. Symptoms of PTSD can include flashbacks, nightmares, anxiety, and depression.
Anxiety and Fear: Even if someone does not develop PTSD, they may experience anxiety and fear related to electricity or fire.
Loss of Property: The loss of property in an electrical fire can be devastating.

If you have experienced an electrical fire and are struggling to cope, it is important to seek professional help. A therapist or counselor can help you process your emotions and develop coping mechanisms.
