Warning signs: flickering lights, burning smells, charred outlets, etc
Electrical fires can be extremely dangerous, and it is important to be vigilant about warning signs. Some of the most common warning signs of electrical fires include flickering or dimming lights, burning smells, and charred or discoloured outlets.
Flickering or dimming lights often indicate one or more poor connections in your home's electrical system. This can cause arcing, which produces sparks and high heat that can ignite combustible materials such as wallboard and wood framing. If you notice your lights flickering, make a note of where it happens and contact a licensed electrician to investigate.
Burning smells from outlets or persistent burning smells from a specific appliance or room in your home can indicate a potential electrical fire. This is especially true if the smell persists over time or spreads throughout your home, as it can point to an electrical fire already in progress. If you experience this, switch off all devices, evacuate the area, and call your local fire department or an electrician to inspect the property.
Discoloured or charred outlets can also be a warning sign of an electrical fire. This can be caused by electrical arcing in the outlets, which produces high heat that can melt the outlet or leave burn marks. If you notice char marks on your outlets, shut off the breaker to that outlet and call an electrician.
In addition to these warning signs, other signs of potential electrical fires include frequent tripped breakers or blown fuses, sparks or flames coming from outlets, and outlets that are hot to the touch. If you notice any of these warning signs, it is important to take action immediately to prevent potential injury or damage to your home.

Aluminium wiring: old wiring may contain aluminium, which corrodes faster than copper
Aluminium wiring was commonly used in the 1960s and 1970s instead of copper wiring, which was becoming more expensive. However, over time, aluminium wiring can degrade and corrode faster than copper wiring, increasing the risk of electrical fires.
Aluminium wiring is prone to disintegration, which creates resistance to the electricity passing through. This impedes the flow of electricity to outlets and causes the wires to become excessively hot. The wires can ignite surrounding building materials, leading to a potential fire. The terminals and splices of aluminium wiring are known for overheating, and the connections can loosen over time. As aluminium expands more than copper when heated, the wiring can also fracture inside the sheathing, causing further issues.
The Consumer Product Safety Commission (CPSC) has linked aluminium wiring to electrical fires. They have found that homes with pre-1972 aluminium wiring are at a 550% higher risk of electrical outlet fire hazards than homes with copper wiring. This highlights the serious safety risks associated with old aluminium wiring.
If you suspect your home may have aluminium wiring, look for any exposed sections of wiring with the word "aluminium" embossed on them. You can also hire a licensed electrician to perform a thorough inspection and provide professional advice. A temporary solution is to install copper connectors ("pigtails") at receptacles and circuit breakers to mitigate the risk until a more permanent solution is implemented.
It is important to address aluminium wiring safety concerns promptly to ensure the safety of your home and family.

Overloaded circuits: overloading outlets can cause too much heat in one location
Overloading outlets can cause too much heat in one location, leading to electrical fires. This happens when more electricity is drawn through a circuit than it is designed to handle. The wires heat up and can ignite anything flammable nearby.
To prevent this, it is important to never overload outlets. This includes running too many cords in one outlet or using an extension cord instead of an outlet. Plugs should always fit snugly into outlets. If plugs are not fitting tightly, the loose connection can generate excess heat and start a fire.
Other warning signs of overloaded circuits include a burning smell, discoloured or charred outlets, and outlets that are hot to the touch. If you notice any of these signs, shut off the breaker to that outlet and call an electrician.
To further prevent the risk of electrical fires, it is recommended to upgrade standard circuit breakers to arc-fault circuit interrupters (AFCIs). These detect abnormal electrical sparks and shut down the circuit before it overheats. Additionally, regularly inspecting your electrical system and using appliances wisely can help prevent overloaded circuits and the risk of electrical fires.

Arcing: a break in an electrical circuit can cause sparks and high heat
Arcing is a serious electrical issue that can cause electrical fires. It occurs when there is a break in an electrical circuit, causing the current to jump across the gap and produce sparks and high heat. This can lead to a fire if the sparks connect with combustible materials in the surrounding area.
To detect arcing in your walls, look out for flickering or dimming lights, which often indicate poor connections in your electrical system. These spots of poor connection can produce heat through arcing, potentially igniting combustible materials such as wallboard and wood framing. If you notice persistent flickering or dimming in certain areas, contact a licensed electrician to investigate and address the issue.
Another warning sign of arcing is repeated instances of tripped breakers, blown fuses, or circuit breakers that won't reset. While an occasional blown fuse or tripped circuit breaker is normal, frequent occurrences may indicate an electrical problem such as a short circuit or overloaded circuit. Short circuits can be caused by issues such as animal damage to wires, faulty electrical switches or appliances, or the hot and neutral wires coming into contact, resulting in high temperatures and a potential fire hazard.
If you suspect arcing or electrical problems, it is important to take prompt action. Turn off the appliance or device and the circuit involved in the sparking to interrupt the flow of electricity. Clearly label your circuits to facilitate quick identification and response during emergencies. Unplug the appliance from the outlet to discharge any remaining electricity and reduce the risk of fire spread.
To prevent arcing and electrical fires, ensure that your outlets are not overloaded with too many cords or plugs. Check for moisture on appliance cords and around outlets, as water can conduct electricity and cause arcing. Regularly inspect your wiring and consider upgrading to modern copper wiring if your home has older aluminum wiring, which is more prone to oxidation and corrosion.
