What You'll Learn
Electric heaters and fire risk
Electric heaters can pose a fire risk, particularly if they are portable. The U.S. Consumer Product Safety Commission estimates that portable electric heaters are involved in about 1,100 fires per year, resulting in around 50 deaths, many injuries, and millions of dollars in property loss.
The National Fire Protection Agency (NFPA) states that heating equipment is a leading cause of fires in U.S. homes, with local fire departments responding to an average of 52,050 fires involving heating equipment per year from 2012-2016. This accounted for 15% of all reported home fires during this period. The NFPA also reports that more than half of all home heating fire deaths resulted from fires that began when a heater was positioned too close to things that could burn, such as furniture, clothing, mattresses, or bedding.
Overheating is a common cause of electric heater fires, especially if there are flammable materials nearby. Electric heaters use a lot of energy and can easily overload circuits, causing a power failure or fire. It is important to ensure that a space heater is not placed near any combustible materials, such as a plastic waste receptacle under a desk, as this could create a significant fire risk.
To reduce the risk of fire, it is recommended to buy a unit with a tip-over safety switch, which automatically shuts off the heater if it is knocked over. Space heaters should be plugged directly into an outlet, rather than into an extension cord, due to the amount of current they draw.

Electric heaters and carbon monoxide poisoning
Electric heaters are generally considered safe and efficient for indoor heating, avoiding the risk of carbon monoxide poisoning. However, it is important to prioritize safety and follow certain guidelines to ensure a comfortable and hazard-free experience.
Firstly, it is crucial to only plug electric heaters directly into wall outlets. Ensure that the power cord does not cross walkways, and avoid running the cord under rugs or carpets, as this can cause damage. Never use extension cords or power strips, and always check that the plug fits tightly into the outlet. Additionally, establish a safety zone of at least 3 feet around the heater, keeping it away from walls and any combustible materials, such as curtains, bedding, and furniture.
While electric heaters themselves do not typically release carbon monoxide, there are certain scenarios where carbon monoxide poisoning can occur. For example, if the heater is faulty, unserviced, or used in a poorly ventilated area, there is a risk of carbon monoxide buildup. Carbon monoxide is a colorless, odorless, and highly poisonous gas that can cause serious health issues, including nausea, dizziness, headaches, and even death. Therefore, it is essential to maintain your heater by regularly servicing it and ensuring proper ventilation in the room.
In rare cases, electric heaters with manufacturing defects may cause the heating element or plastic to burn, potentially producing carbon monoxide. Additionally, dust accumulation on the heating elements can burn and generate smoke, which can also lead to carbon monoxide production. However, you would typically smell the dust burning in such cases.
To summarize, while electric heaters are generally safe regarding carbon monoxide poisoning, it is crucial to prioritize safety by following the provided guidelines, maintaining proper ventilation, and regularly servicing your heater to prevent any potential hazards.

Electric heaters and shock hazards
Electric heaters can pose a serious risk of shock and electrocution. Water heaters, in particular, have been known to cause shocks when water comes into direct contact with the heating element. Such heaters should not be used in areas where moisture creates a shock hazard, such as bathrooms, kitchens, or near windows or doors subject to heavy condensation.
Portable electric heaters can also cause fires or smoke inhalation injuries if there are flammable materials nearby. They can easily overload circuits, causing power failures or fires, and they may also cause asphyxiation due to carbon monoxide emissions if not properly vented. The U.S. Consumer Product Safety Commission estimates that portable electric heaters are involved in about 1,100 fires per year, resulting in about 50 deaths, dozens of injuries, and millions of dollars in property loss.
To reduce the risk of shock and fire hazards, it is important to establish a safety zone around electric heaters. Keep the heater at least 3 feet away from walls and combustible materials such as furniture, bedding, curtains, and clothing. Always plug the heater directly into a wall outlet, ensuring the power cord is not damaged, does not cross a walkway, and fits tightly into the outlet. Never use extension cords or power strips.
It is also important to regularly check and maintain your heater during the season. Remove dust and debris from the heater when it is not in use to reduce fire hazards. Additionally, look for recalls on the Consumer Product Safety Commission website to ensure your heater has not been recalled due to safety issues.

Electric heaters and extension cords
Electric heaters can pose an asphyxiation risk if they cause a fire or emit carbon monoxide. The U.S. Consumer Product Safety Commission estimates that portable electric heaters are involved in about 1,100 fires per year, resulting in about 50 deaths, dozens of injuries, and millions of dollars in property loss.
When using an electric heater, it is important to follow safety precautions to reduce the risk of fire and asphyxiation. This includes keeping the heater away from flammable materials, such as upholstered furniture, clothing, mattresses, or bedding, and ensuring proper ventilation if using a fuel-burning heater to avoid carbon monoxide buildup.
Now, let's discuss the use of extension cords with electric heaters. The majority of electric heaters recommend against using an extension cord and this advice is often echoed by fire safety organizations. The main concern is the increased risk of fire due to overheating. Extension cords can have higher resistance, causing them to heat up and potentially start a fire. Additionally, there is a risk of tripping over the extension cord, which can move the heater into a dangerous position, such as onto curtains or clothing.
However, some people argue that using a good quality extension cord, such as a 12-gauge cord, and taking proper precautions can minimize the risk. If you must use an extension cord with an electric heater, it is important to follow these safety guidelines:
- Use a short extension cord of adequate gauge, such as a 12-gauge cord, to reduce resistance and overheating.
- Ensure that the extension cord is not worn or damaged, as it may melt or catch fire.
- Do not plug multiple heating appliances into the same extension cord to avoid overloading the circuit.
- Keep the extension cord visible and accessible to regularly check for any signs of overheating.
- Avoid covering the extension cord to prevent tripping, as it can increase the risk of overheating.

Electric heaters and safety precautions
Electric heaters can pose a risk of asphyxiation, albeit indirectly. While electric heaters do not emit carbon monoxide, they can cause fires or smoke inhalation injuries if they overheat and there are flammable materials nearby. This can, in turn, lead to asphyxiation from carbon monoxide or other combustion products.
To prevent this, it is important to take several safety precautions when using electric heaters. Firstly, ensure that the heater bears the seal of a nationally recognized testing laboratory, such as UL (Underwriters Laboratories), CSA (Canadian Standards Association), or ETL (Intertek). These laboratories test heaters for potential safety hazards, such as the risk of fire or overheating.
Another important precaution is to avoid plugging other electrical devices or extension cords into the same outlet as the heater. This can cause overheating, leading to a potential fire hazard. Instead, always plug electric heaters directly into a wall outlet and ensure that the cord is not covered by an area rug or furniture, as this can also cause overheating or damage.
Additionally, it is crucial to maintain a safe distance between the heater and flammable objects such as furniture, clothing, mattresses, or bedding. Keep the heater away from areas where children or pets may play, as knocking it over could be a safety hazard. For added safety, consider purchasing a heater with a tip-over safety switch, which automatically shuts off the heater if it is knocked over.
Finally, install working smoke alarms and carbon monoxide detectors on every level of your home and in every bedroom. Test them monthly to ensure they are functioning properly. By following these safety precautions, you can help reduce the risk of fire, smoke inhalation, and asphyxiation associated with electric heater use.
