Fire hazards

Fire safety is a crucial consideration when burning candles, especially in an enclosed space like a bedroom. The National Fire Protection Association (NFPA) reports that firefighters respond to approximately 7,400 structure fires in the US caused by candles annually, resulting in an average of 90 deaths, 670 injuries, and nearly $300 million in property damage.

To minimise fire hazards when burning a candle in your room, follow these essential safety tips:

Ventilation

Proper ventilation is critical when burning candles. In an enclosed, unventilated room, candles can produce small amounts of carbon monoxide, which can lead to mild exposure symptoms such as headaches, dizziness, or nausea. Always ensure your room is well-ventilated by opening windows or doors to allow fresh air to circulate and reduce the risk of carbon monoxide build-up.

Candle Placement

Place your candle in a safe location, away from anything flammable or items that could easily catch fire if the candle is knocked over. Avoid placing candles near curtains, bedding, or other flammable materials. The recommended placement for a candle in an indoor setting is an end table next to a couch or chair.

Wick Maintenance

Maintain the wick of your candle by trimming it regularly to a length of 5 to 10 millimetres. A long wick can cause the candle to burn unevenly, leading to a higher flame and an increased fire risk. Additionally, always ensure the wick is upright and centred before lighting the candle.

Burning Time

Avoid letting your candle burn for extended periods. Extinguish the candle when you leave the room or before going to sleep. If you notice the candle is getting low, put it out, even if it seems to have a few hours of burning time left.

Candle Condition

Always inspect your candle before lighting it. Discard any candle with a broken or dirty wick, as this can cause uneven burning and increase the risk of fire. Also, check for any signs of damage to the candle container or surrounding wax, as this could indicate that the candle is not safe to burn.

By following these fire safety precautions, you can minimise the risk of fire hazards when burning a candle in your room and enjoy the ambiance and fragrance of candles responsibly.

Health risks

Burning candles can release hydrocarbons, such as toluene and benzene, into the air. Toluene is commonly used in paint thinners and adhesives, and exposure to it without proper ventilation can irritate the eyes, nose, throat, and skin, as well as cause headaches, dizziness, confusion, and anxiety. Benzene is a known carcinogen, increasing the risk of leukaemia and other blood cancers. While candles do release these compounds, the amounts are relatively small and are not cause for concern unless you are exposed to significant quantities or for prolonged periods.

In addition, burning candles can release volatile organic compounds (VOCs) such as formaldehyde and benzine, which may increase the risk of cancer. However, an older study from 2014 found that the amount of particulate matter released from candles is not enough to cause health problems in humans. Furthermore, scented candles release less than half of the recommended amount of VOCs set by the World Health Organization (WHO).

Another concern is carbon monoxide poisoning. While rare, burning candles in an enclosed space without proper ventilation can lead to mild carbon monoxide poisoning, causing symptoms such as headaches, dizziness, or nausea.

To minimise the potential health risks associated with burning candles, it is important to always burn them in a well-ventilated space. Opening windows or doors can help ventilate the room and prevent a buildup of smoke and scent molecules, reducing the risk of inhaling harmful chemicals. Additionally, choosing candles made from natural sources, such as palm stearin, can help minimise the amount of particulate matter released.

Ventilation

Burning candles emit hydrocarbons, including toluene and benzene, which can be irritating to the eyes, nose, throat, and skin. Toluene exposure without proper ventilation can cause headaches, dizziness, confusion, and anxiety. Benzene is a known carcinogen, increasing the risk of leukaemia and other blood cancers. However, it's important to note that the amount of these compounds released by candles is relatively small and not a significant health concern when used in a well-ventilated space.

To ensure proper ventilation when burning candles in your bedroom, keep the doors and windows open. This will allow the scent to fill the room more effectively and prevent a buildup of smoke and scent molecules. Even a slightly open window or a small gap under the door can provide sufficient ventilation.

Additionally, be mindful of the placement of your candle. Keep it away from drafts, as this can reduce the amount of smoke produced. Place the candle on an end table next to a couch or chair, ensuring it is not near any flammable items or furniture that could catch fire if the candle is knocked over.

By following these ventilation tips and practising candle safety, you can safely enjoy the benefits of candles in your bedroom without compromising your health or safety.

Candle maintenance

Burning candles can release potentially harmful toxins and VOCs (carbon compounds that easily turn into gas at room temperature). However, there is no definitive research that proves exposure to candle smoke increases the risk of developing health conditions. Nevertheless, it is recommended to burn candles in a well-ventilated room to minimise the amount of smoke inhaled.

Before Lighting the Candle

  • Trim the wick to about 5-6mm in length. This will avoid "mushrooming", which can result in unnecessary soot and control the size of the flame.
  • Keep the wax pool free of wick trimmings, matches, and debris.
  • Ensure the candle is placed on an end table next to a couch or chair, away from anything flammable.

While the Candle is Burning

  • For the first burn, let the candle burn for 2-4 hours until the wax melts across the entire surface to prevent tunnelling and create an even burn.
  • Avoid burning the candle for extended periods, especially during the first use. Keep sessions to around four hours.
  • Keep the candle away from drafts to decrease smoke and improve scent throw.
  • Open doors to ventilate the space and allow the scent to fill the room effectively.

Extinguishing the Candle

  • Avoid blowing out the candle, as this can create smoke and disturb the wax pool.
  • Instead, use a candle snuffer to gently extinguish the flame, preserving the candle's fragrance and preventing soot from forming.
  • Alternatively, dip the wick into the melted wax and then straighten it.

Storage

  • Store candles in a cool, dark place away from direct sunlight and extreme temperatures.
  • Proper storage can extend their shelf life and maintain their quality.

Scent

While candles are often used to fill a room with fragrance, there are some safety considerations to keep in mind when burning scented candles in your room.

Firstly, it is important to ensure that your candle is made from natural sources, as these candles release the least amount of particulate matter and dangerous chemicals. For example, candles made from palm stearin release half as much soot as those made from paraffin. Natural candles are therefore the best option for minimising the amount of potentially harmful substances you breathe in.

In addition, it is crucial to burn scented candles in a well-ventilated space. Burning candles can release hydrocarbons, which are chemical compounds consisting of hydrogen and carbon, as well as trace amounts of toluene and benzene. Toluene exposure can cause irritation to the eyes, nose, throat, and skin, as well as headaches, dizziness, confusion, and anxiety. Benzene, on the other hand, is a known carcinogen, increasing the risk of leukaemia and other blood cancers. While the amount of these substances released by candles is small, proper ventilation is necessary to prevent adverse health effects. Opening windows or doors can help ventilate the space and allow the scent to fill the room more effectively.

Furthermore, it is important to follow general candle safety guidelines to minimise the risk of fire. Keep candles away from anything flammable and ensure that the wick is trimmed to a length of 5 to 10 millimetres. Burning a candle for too long can also be a fire hazard, so it is recommended to extinguish the candle before it reaches the bottom of the container.

Overall, while scented candles can be enjoyed safely in your room, it is important to take the necessary precautions to minimise any potential health and safety risks.
