Electrical fires can be extremely dangerous, and they often start from overloading and bad wiring. The smell of an electrical fire is very distinct and is often described as acrid and similar to burning plastic or rubber. This is because the insulation on wires and connectors is made from plastic and will burn when it gets too hot. Other signs of an electrical fire include flickering or discoloured lights, buzzing sounds, and exposed wires. If you suspect an electrical fire, it is important to act quickly by shutting off the power, evacuating the premises, and calling emergency services.

What You'll Learn
Burning plastic
The acrid, chemical odour of burning plastic is hard to miss and often indicates something is wrong. Electrical fires commonly cause a burning plastic smell, as the insulation around wires starts to burn and melt, releasing toxic fumes. If you smell burning plastic, it's important to act quickly to prevent a fire from starting or spreading.
First, determine where the smell is coming from. If there is smoke or fire, or you are extremely concerned, call the emergency services. Otherwise, turn off and unplug any devices or appliances associated with the smell. Shut off the power to that area of the home. Then, call an electrician to assess the situation and locate the source of the burning plastic smell.
A burning plastic smell could indicate faulty electrical wiring or an appliance overheating. It may be caused by dust and dirt build-up, or a malfunctioning HVAC system. The smell could also be caused by small plastic items that have found their way close to heating elements.
The toxic fumes from burning plastic are a serious health hazard and can irritate the eyes, nose and lungs, causing discomfort and long-term health issues. Inhaling large quantities of these fumes can cause carbon monoxide poisoning, which is dangerous and potentially fatal.

Fishy smell
A fishy smell is one of the most commonly reported indicators of an electrical fire. Electrical wiring is covered in a layer of flexible PVC insulation. When the wiring overheats, the PVC also gets hot and gives off chemical fumes as it smoulders, which can smell fishy. This fishy smell is particularly noticeable in electric shower connections.
The fishy odour is often the first sign of an electrical fire that is not otherwise detectable. The smell is caused by electrical components overheating but not yet burning up. The heat-resistant chemical coatings on the components can also release a fishy odour when burned. The fishy smell can be hard to detect, as it can be attributed to something cooked in the kitchen. However, if there is no reason for a fishy smell, it is important to take action to prevent a potential electrical fire.
If you smell something fishy, it is recommended to turn off the circuit breakers and call an electrician for an emergency inspection to identify the source of the problem. It is also advised to locate your MAIN SWITCH, which is the home's main circuit breaker, and shut off the power supply to your property. This will turn off the lights, plug sockets, and other electrical supplies, allowing the wiring to cool down and preventing the issue from escalating.
It is crucial to address the fishy smell early on, as electrical fires can be extremely dangerous and even deadly. They are a common threat, causing 13% of house fires and resulting in significant property damage. Therefore, it is important to be vigilant and take the necessary steps to prevent electrical fires from spreading.

Urine-like odour
The smell of an electrical fire is often described as "fishy" or similar to burning plastic or rubber. This is due to the combustion of plastic elements like wires or insulation, which release fumes that smell fishy. However, some people perceive the odour of overheated electrical components as urine-like. This urine-like odour is a warning sign that there is an issue somewhere in your electrical system, which may lead to an electrical fire.
The urine-like smell is distinct and should prompt you to take immediate action. First, turn off the power and try to locate the source of the smell. If the problem is not evident in an appliance or an overloaded power strip, the cause could be hidden in the walls of your home. Check outlets, light switches, and all connected appliances for damage or signs of fire. Charred outlets, flickering or buzzing lights, electric sparks, and exposed wires due to degrading insulation are all red flags.
If you cannot identify the source, or if there are any signs of fire, evacuate the premises and contact the fire department or a licensed electrician. It is crucial to act quickly to prevent a potential fire from spreading. Electrical fires can pose significant hazards, and the smoke and fumes released can be toxic, causing respiratory issues, eye irritation, and other health problems.
To prevent electrical fires and odours, it is important to maintain your electrical system properly. This includes avoiding overloading circuits and ensuring that wiring is correctly insulated. Regular inspections by a licensed electrician can help identify potential issues and ensure the safe functioning of your electrical system. Taking prompt action when noticing any unusual odours or signs of electrical malfunction is crucial for maintaining safety.
In summary, a urine-like odour indicates a potential electrical issue and should not be ignored. Taking immediate action, such as turning off the power, locating the source, and seeking professional help, is essential to prevent fires and ensure your safety. Electrical fires can be dangerous, and addressing them promptly can help mitigate risks to both property and health.

Ozone
The smell of ozone is an important warning sign that should not be ignored. If you detect this odour, it is recommended that you take immediate action by turning off the power, locating the source of the smell, and seeking professional help from a licensed electrician. Electrical fires can be extremely dangerous and pose significant hazards, so it is crucial to act quickly and prioritize safety.
In addition to the smell of ozone, other indicators of an electrical fire include flickering or dimming lights, buzzing sounds from switches or outlets, discoloured or charred outlets, and exposed or frayed wires. These signs should also prompt you to take the necessary precautions to ensure your safety and mitigate any potential risks.
It is always better to be cautious and take preventive measures when dealing with electrical fires or potential hazards. By recognizing the smell of ozone and other warning signs, you can proactively protect yourself, your home, and your loved ones from the devastating consequences of electrical fires.

Metallic smell
An electrical fire can emit a range of distinct odours, 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, such as wires or insulation, which can result in an acrid, pungent scent.
However, it is important to note that not all electrical fires produce a burning plastic smell. Some people may perceive a metallic odour, which is typically attributed to electrical arcing or the overheating of metal parts. This metallic smell can be a warning sign of an electrical fire, indicating that immediate action is required to ensure safety.
The smell of an electrical fire involving metal parts can be sharp and unpleasant. It may resemble the scent of burning metal or overheated electrical components. This odour is often described as distinct and different from the smell of burning wood or paper. It is crucial to prioritise safety and take prompt action if you suspect an electrical fire.
If you detect a metallic smell that suggests an electrical fire, it is essential to act quickly. Turn off the power at the main source to prevent further damage and potential hazards. Evacuate the premises and ensure that you and others maintain a safe distance. Contact emergency services or a licensed electrician to address the issue and identify the source of the smell.
Additionally, it is worth mentioning that electrical fires can sometimes emit a fishy odour, particularly in the early stages. This smell is caused by the heating of electrical components, such as wires or connectors, before they reach the point of combustion. Therefore, if you smell something fishy without any apparent explanation, it could be an indication of an electrical fire, and you should take the necessary precautions.
