What You Can Do Safely at Home

• Use extension cords only for temporary power needs, not as permanent wiring.
• Choose cords rated for the power load and environment (indoor or outdoor use).
• Inspect cords regularly for damage, such as frayed wires or cracked insulation.
• Keep cords away from water, heat sources, and high-traffic areas to prevent damage and tripping.
• Unplug cords by holding the plug, not the cord itself.

What to Avoid

• Do not overload extension cords by plugging in too many devices.
• Avoid running cords under rugs, through doorways, or across walkways.
• Never use damaged or repaired cords.
• Do not connect multiple extension cords together (daisy-chaining).

When to Call for Help

If you or someone else experiences an electrical shock, burns, or if you see smoke or fire caused by an extension cord, call 911 or your local emergency services immediately. Do not attempt to handle electrical fires with water; use a fire extinguisher rated for electrical fires if safe to do so.

Key facts

Using extension cords safely helps prevent electrical fires, shocks, and injuries. Follow these key facts to protect yourself and your home.

• Only use extension cords rated for the power needs of your devices. Overloading cords can cause overheating and fire.
• Inspect cords before use. Do not use cords with frayed wires, cracks, or exposed metal parts.
• Never run extension cords under rugs, carpets, or furniture. This traps heat and increases fire risk.
• Use outdoor-rated extension cords only for outdoor purposes. Indoor cords are not designed to withstand weather conditions.
• Do not connect multiple extension cords together. This can cause voltage drops and overheating.
• Unplug extension cords when not in use to reduce the risk of electrical hazards.
• If you notice sparks, burning smells, or the cord feels hot, unplug it immediately and do not use it again.

For any electrical shock, burns, or if a fire starts, call 911 or your local emergency services right away. Do not attempt to handle serious electrical injuries or fires on your own.

Recognizing symptoms and danger signs

When using extension cords, it is important to recognize symptoms that indicate a problem. These symptoms can range from mild to severe and help you decide if you can manage the situation safely at home or need urgent care.

Mild symptoms

Mild symptoms often include:

• Warm or slightly hot extension cord surface
• Minor buzzing or crackling sounds
• Flickering lights connected to the cord

If you notice these signs, unplug the cord immediately and inspect it for damage. Do not use the cord again until it is replaced or checked by a qualified electrician.

Moderate symptoms

Moderate symptoms suggest a higher risk and include:

• Visible damage such as frayed wires or exposed conductors
• Burn marks or melted insulation
• Persistent sparking or smoke near the cord

Stop using the extension cord at once. Avoid touching it and keep others away. Contact a professional electrician to assess the situation. Do not attempt repairs yourself.

Severe symptoms and red flags

Severe symptoms require immediate emergency response. Call 911 or your local emergency number if you observe:

• Fire or flames coming from the extension cord or outlet
• Electric shock symptoms such as numbness, tingling, or muscle spasms
• Loss of consciousness or difficulty breathing after contact with the cord

These signs indicate a life-threatening emergency. Do not delay calling for help.

By understanding these symptoms and danger signs, you can ensure the safe use of extension cords and protect yourself and others from electrical hazards.

Immediate first aid steps

When dealing with injuries related to the safe use of extension cords, quick and careful action can prevent further harm. Follow these steps to provide safe first aid at home or in the community while waiting for professional help if needed.

Assess the situation safely

• Do not touch the person if they are still in contact with a plugged-in or damaged extension cord.
• If safe, unplug the cord or switch off the power at the breaker before approaching.
• Call 911 immediately if the person is unresponsive, has difficulty breathing, or shows signs of severe burns or shock.

Provide basic first aid

• If the person is conscious and breathing, check for burns or injuries.
• For minor burns, cool the area with running cool (not cold) water for at least 10 minutes.
• Cover burns loosely with a clean, non-stick dressing or cloth.
• Do not apply creams, ointments, or ice directly to the burn.
• If there is any sign of electrical injury beyond minor burns, such as numbness, weakness, or irregular heartbeat, seek urgent medical care.

When to seek emergency care

• Call 911 if the person is unconscious, has a seizure, or shows signs of cardiac arrest.
• Go to the emergency department or urgent care for burns larger than the palm of the hand or if the burn is on the face, hands, feet, or genitals.
• Seek medical attention if the person experiences persistent pain, swelling, or signs of infection after initial first aid.

Following these immediate first aid steps ensures the safe use of extension cords and helps reduce the risk of serious injury. Always prioritise safety and call for professional help when in doubt.

What NOT to do

When using extension cords, certain actions can create serious hazards. Avoid these unsafe practices to protect yourself and others from electrical shock, fire, or injury. The safe use of extension cords depends on following clear rules and avoiding common mistakes.

Do NOT overload extension cords

Never plug too many devices into one extension cord. Overloading can cause overheating and start a fire. Check the cord’s rating and do not exceed its maximum wattage.

Do NOT use damaged or frayed cords

Using cords with exposed wires, cracks, or broken plugs is dangerous. Replace damaged cords immediately. Do not attempt to repair them with tape or other materials.

Do NOT run cords under rugs or furniture

Extension cords hidden under carpets or heavy furniture can overheat and cause fires. Always keep cords visible and free from heavy pressure.

Do NOT use outdoor cords indoors or vice versa

Outdoor extension cords are designed to withstand weather but may not be safe indoors. Similarly, indoor cords lack protection from moisture and should not be used outside.

Do NOT ignore signs of electrical problems

• Do not ignore sparks, burning smells, or unusual heat from cords or plugs.
• If you notice these signs, unplug the cord immediately and stop using it.
• Call 911 or your local emergency services if a fire starts or if someone receives an electric shock.

Following these guidelines helps ensure the safe use of extension cords and reduces the risk of accidents at home.
