Candles are a common cause of house fires, with open flames posing a significant fire risk. The careless use of candles causes nearly 10,000 residential fires annually in the US, according to the National Fire Protection Association. Candle fires can start when the candle is knocked over, or when the liquid wax ignites, causing a larger-than-intended flame. This can lead to nearby objects catching fire, especially if the candle is left unattended. To prevent candle fires, it is crucial to never leave a burning candle unattended, keep candles away from flammable objects, and ensure proper ventilation to prevent rapid or uneven burning. Additionally, keeping wicks trimmed and using candleholders designed for candle use can help mitigate the risk of fire.

What You'll Learn
Flashovers
Candles are a potential fire hazard if not carefully monitored. Candle fires cause an estimated 15,600 house fires, 150 deaths, and 1,270 injuries each year, resulting in 3% of all fire-related incidents.
One of the ways in which candles can cause fires is through a phenomenon known as "flashover". A candle flashover occurs when the liquid wax itself ignites and burns, instead of just the wick. This results in a far larger and stronger flame than intended, which may begin spitting little balls of fire. If left unattended, this may be enough to start a fire.
To prevent flashovers, it is important to never leave a candle unattended and to always extinguish any candle before leaving the room. Additionally, candles should be placed in sturdy holders to prevent them from being knocked over, and they should be kept away from flammable objects such as curtains, furniture, and clothing. It is also important to keep the wick trimmed to 1/4 inch to prevent the candle from catching fire due to overextending itself.

Unattended candles
Leaving a candle unattended is one of the most common ways that candles cause fires. Even if you think you will only be gone for a moment, accidents can happen. It is best to always extinguish any candle before leaving the room and ensure it is completely out with no glowing wick ember.
Candles should never be left burning overnight. This raises the risk of the candle being knocked over, either by a person, pet, or even a strong wind or a large insect. A knocked-over candle can easily start a fire, especially if it falls onto something flammable. Even if it does not fall onto something flammable, the liquid wax can ignite, creating a larger and stronger flame than intended, which may be enough to start a fire.
Candles should also not be burned down completely, as this can cause the candle container to break or the surface underneath to catch fire. Discontinue burning a candle when there is still wax remaining in the container—at least two inches for a regular candle, and half an inch for a candle in a container.
In addition, candles should be placed in a holder or container to prevent them from being knocked over. The container should be heat-resistant and sturdy, and it should be large enough to contain any drips or melted wax. Glass jars are considered best practice, as they prevent the open flame from touching anything flammable.
Finally, it is important to keep candles away from flammable objects. This includes curtains, furniture, paper, plants, and electronics. Keep candles at least one foot away from any potentially flammable objects, and never burn a candle on or near anything that could catch fire.

Poor ventilation
While the amounts of these chemicals released by candles are small, they can still be a cause for concern in certain situations. In addition, paraffin (petroleum-based) candles and scented or aromatic candles are the most common types of candles and the worst offenders for indoor air pollution. This pollution can contaminate the ductwork in ventilation systems and discolour walls and ceilings.
Burning candles for extended periods without proper ventilation can also cause a build-up of heat in a room, increasing the risk of flashovers, where the liquid wax ignites and creates a larger and stronger flame. This can lead to a house fire, especially if there are flammable objects nearby.
To ensure proper ventilation when burning candles, follow these safety tips:
- Burn candles for no longer than four hours at a time.
- Allow candles to cool for at least two hours before relighting.
- Place candles in a well-ventilated room, away from drafts, vents, or air currents to prevent rapid or uneven burning, sooting, and excessive dripping.
- Use beeswax or soy candles, as they burn cleaner than paraffin wax candles.
- Ensure the room has adequate airflow to prevent a build-up of heat and pollutants.
- Consider using alternative fragrance sources, such as diffusers with essential oils, to reduce the number of burning candles needed.

Knocked over by pets
Candles are a potential fire hazard if not carefully monitored. A leading cause of candle-related fires is when pets knock them over. Pets, especially cats and dogs, can accidentally knock over candles with their paws or tails. This can happen when they are playing, strolling by, or jumping up to reach something. Additionally, some dogs may be attracted to the smell or taste of the candle and intentionally get too close.
To prevent fires caused by pets knocking over candles, it is important to always keep candles out of the reach of pets. Place them on high surfaces that are less likely to catch fire if the candle is knocked over. Avoid placing candles near flammable objects, such as fabrics, paper, or liquids. Use sturdy candleholders or heavy-based hurricane lamps to prevent candles from being knocked over.
Battery-powered flameless candles or LED alternatives are a safer option if you have pets. These candles provide the same relaxing glow without the risk of an open flame. Air diffusers, natural odor neutralizers, and air purifiers are also pet-friendly options for creating a pleasant-smelling environment.
It is important to be cautious when using scented candles around dogs, as some candles contain essential oils and ingredients that can be harmful or toxic to dogs if inhaled, ingested, or absorbed through their skin. Always opt for pet-safe alternatives, and give your pet the option to leave the room if they do not like a particular scent.
By following these precautions, you can significantly reduce the risk of candle-related fires caused by pets and create a safer environment for both you and your furry companions.

Incorrect wick trimming
A wick that is too long can also cause uneven burning, dripping, or flaring. This can lead to a larger and stronger flame than intended, which may result in fireballs being spat out. Additionally, a wick that is too long can cause the candle to burn down too quickly, reducing its lifespan.
On the other hand, a wick that is too short can also be problematic. If the wick is trimmed too short, it may be difficult to light and can cause the candle to burn unevenly. This can result in tunnelling, where only a small area of wax around the wick melts, creating a small hole instead of allowing the entire surface of the wax to melt. Tunnelling can be fixed by lighting the candle and allowing it to burn evenly for 30 minutes to a few hours, depending on the candle size.
To ensure proper wick trimming, it is recommended to trim the wick before lighting the candle and to use a wick trimmer, nail clippers, or scissors. It is also important to keep the wax pool clear of wick trimmings, matches, and other debris to prevent fires.
