Electrical fires are a serious hazard that can start in a number of ways, from overloaded circuits to faulty switches or outlets. They can be particularly dangerous because they often start behind walls, and by the time you see them, it may be too late. One of the best ways to detect an electrical fire is by its distinctive smell. But what does an electrical fire smell like?

What You'll Learn
Burning plastic
A burning plastic smell is indicative of faulty electrical wiring, which can be dangerous. Electrical fires can start behind walls and spread quickly, so it's important to act fast if you notice this smell. Turn off the power and unplug any associated devices. If there is smoke or fire, call the emergency services. Otherwise, contact an electrician to check your wiring and prevent further damage or a potential fire.
The burning plastic smell is caused by the insulation around wires burning and releasing toxic chemical odours. These fumes can irritate your eyes, nose and lungs and cause discomfort and long-term health issues. Inhaling large quantities of these fumes can cause carbon monoxide poisoning, which is life-threatening.
The smell of burning plastic could be coming from a number of household items and appliances. For example, kitchen appliances such as microwaves, dishwashers, blow dryers and curling irons can all emit a burning plastic smell. It could also be caused by dirt and grime buildup or gas leaks in HVAC systems, or by dust in air ducts and malfunctioning AC or furnace motors.
If you can't identify the source of the burning plastic smell, it's important to call an electrician to inspect your home as soon as possible. Take a systematic approach to finding the source of the smell to prevent further hazards. Open windows and doors to ventilate your home and disperse harmful fumes.

Burning rubber
The sharp, acrid scent of burning rubber is a warning sign that you should not ignore. It could be something minor, like an overheating appliance, or it could be something much more serious, like a fire or electrical issue hidden behind your walls.
If you smell burning rubber, act quickly to identify the source of the acrid, chemical smell and take the right steps to keep your home safe. It could be caused by a faulty appliance, such as a washing machine, with a motor that has overheated and melted wiring insulation. A burning rubber smell could also be caused by a clogged air filter, an overheating motor, or a worn-out fan belt in your HVAC system. If the smell is coming from your vents, shut off your HVAC system and call a technician for an inspection.
If you suspect an electrical issue, turn off the power to the affected area and call an electrician immediately. Overloaded circuits can cause wires to overheat, melt, and release a distinct burning odour, which can ultimately lead to components overheating and potentially catching fire if not addressed promptly.
If you notice any other warning signs of an electrical fire, such as a circuit breaker that trips frequently or for no apparent reason, sparking outlets, or flickering lights, call an electrician to help remedy the situation before a fire starts.

Fishy smell
A fishy smell in your home could indicate an electrical fire. While some people associate the smell of electrical fires with burning plastic or rubber, others have reported a fishy odour. This is caused by the chemicals used in wires, outlets, and breakers. These chemicals release a fishy odour when they overheat, which can happen when there is an electrical short or overloaded circuit.
If you smell a fishy odour in your home, it is important to act quickly. First, check if there is any sign of an active fire. If there is, evacuate the premises and call 911 or your local fire department. If there is no sign of a fire, shut off the breakers and call an electrician to inspect your electrical system. Do not ignore a fishy smell, as it could indicate a serious electrical issue that needs to be addressed immediately.
It is worth noting that a fishy smell in your home may also be caused by other factors, such as a dead animal or sewer gas. However, if you have recently cooked fish or there are other obvious explanations for the smell, it is less likely to be an electrical fire. Additionally, if you notice any other warning signs of an electrical fire, such as flickering lights, buzzing sounds, or sparking outlets, it is important to call an electrician to address the issue promptly.
While it may be challenging to pinpoint the source of a fishy smell, especially if it is subtle, it is crucial to prioritise safety. Electrical fires can be dangerous and even deadly, so it is always better to be cautious and consult a professional. Regular electrical safety inspections and preventative measures can also help reduce the risk of electrical fires in your home.
In summary, a fishy smell could indicate an electrical fire, especially if there are no other obvious explanations for the odour. Taking prompt action and contacting the necessary professionals can help ensure your safety and prevent potential disasters.

Metallic odour
An electrical fire can emit a range of smells depending on the materials and components involved. One of the most commonly described smells associated with electrical fires is that of burning or melting plastic. This is due to the combustion of plastic elements like wires or insulation, resulting in an acrid, sharp, and unpleasant odour.
However, another smell that has been reported is a metallic odour. This metallic smell is often accompanied by an ozone scent, which is indicative of electrical arcing. Electrical arcing occurs when electricity jumps across a gap or interrupts a circuit, creating sparks and ozone gas. This phenomenon can be highly dangerous and should not be taken lightly. If you detect a metallic odour, it is imperative to act swiftly and shut off the power to the affected panel. Contact a professional electrician to diagnose and address the issue promptly.
The metallic smell in electrical fires can be attributed to several factors. One possible cause is the oxidation of copper in metallic fixtures, switches, and circuit breakers. Copper fixtures, when exposed to air, can undergo oxidation, resulting in a foul odour. Additionally, metal dust from rusting electrical fixtures, fuses, and switches can contribute to the metallic odour. This metal dust may come into contact with plastic components, leading to a combination of burning plastic and metallic smells.
It is important to note that electrical fires can progress rapidly and pose significant hazards. Therefore, if you detect any unusual smells, especially a metallic odour accompanied by ozone, it is crucial to take immediate action. Prioritize your safety and the safety of those around you by evacuating the premises and contacting the fire department or a qualified electrician.

Toxic fumes
The smell of an electrical fire is often described as a \"burning plastic\" or \"burning rubber\" smell. This is due to the plastic insulation surrounding copper wires melting and releasing toxic chemicals into the air, including ketones and aldehyde gases, which are harmful to inhale. Polychlorinated biphenyl (PCB) by-products are also emitted from electrical burning equipment, which can cause cancer and other serious health issues. The smell of burning plastic typically means the fire has accelerated.
In some cases, an electrical fire may emit a fishy scent, which could be due to the chemicals and agents burning, such as insulation. A fishy smell typically indicates that an electrical fire is just beginning. If you detect this smell, it is important to act quickly as electrical fires can spread rapidly and be extremely dangerous.
The toxic fumes released from an electrical fire can be harmful to your health. Inhaling these fumes can cause respiratory issues and other serious complications. It is important to evacuate the premises immediately and call the fire department to ensure the fire is completely extinguished and there are no lingering issues. Do not attempt to put out the fire yourself unless you have the appropriate equipment and training.
To prevent electrical fires, it is crucial to be aware of the potential hazards and take preventive measures. Regularly inspect your electrical cords, outlets, and appliances for any signs of wear or damage, and replace them immediately if necessary. Keep flammable materials away from heat sources, and ensure that your electrical system is up to code and does not pose any safety hazards.
If you suspect an electrical fire, it is always best to err on the side of caution. Evacuate the premises, call the fire department, and contact a professional electrician to inspect your electrical system and identify the source of the problem.
