Do candles give off carbon monoxide? It’s an important question to ask, especially if you use candles regularly in your home or office. Candles are typically used for their alluring fragrance and calming ambiance, but recent studies have shown that they may have a few drawbacks that aren’t commonly known. One of those drawbacks is carbon monoxide emissions.
Carbon monoxide is a colorless and odorless gas that can be deadly in high concentrations. It’s produced by incomplete combustion of any material that contains carbon, including the wax used in candles. Although the amount of carbon monoxide in the air may not pose a significant risk to your health, it’s essential to understand the potential dangers of burning candles in an enclosed space for an extended period. In this article, we will explore whether candles emit carbon monoxide and the risks associated with their prolonged use.
So, what exactly happens when you light a candle? Well, a chemical reaction occurs between the heat of the flame and the wax. The wax vaporizes and combusts with oxygen in the air, producing water vapor and carbon dioxide. The carbon dioxide is generally harmless in small amounts, but if there’s insufficient oxygen, incomplete combustion can occur, resulting in the production of carbon monoxide. While incomplete combustion isn’t a common occurrence, it’s still important to understand the risks associated with it. So, do candles give off carbon monoxide? The short answer is yes, but we’ll delve into the topic further to provide you with more detailed information.
What is carbon monoxide and its dangers?
Carbon monoxide (CO) is a deadly gas that is both colorless and odorless, which means it’s virtually impossible to detect without proper equipment. CO is produced by incomplete combustion of fossil fuels such as gas, coal, and wood, and can be present in the air we breathe, particularly in enclosed or poorly ventilated spaces. When inhaled, CO binds to hemoglobin in the bloodstream, preventing oxygen from reaching vital organs. This can lead to serious health issues, including headaches, dizziness, nausea, and even death.
- CO poisoning symptoms can often be mistaken for flu-like symptoms, making it difficult to detect without proper equipment and testing.
- Young children, pregnant women, the elderly, and individuals with heart or respiratory problems are particularly vulnerable to the effects of CO poisoning.
- CO detectors are an essential tool for detecting the presence of CO gas and can help prevent serious health issues and fatalities.
It’s important to understand the dangers of carbon monoxide and take proper precautions to prevent exposure. This includes ensuring proper ventilation in enclosed spaces, not using gas-powered equipment indoors, and ensuring gas appliances are properly maintained and regularly inspected by qualified professionals.
Here’s a quick breakdown of the dangers of carbon monoxide:
| Potential Risks | Effects on the Body |
|---|---|
| Exposure to low levels of CO over time | Flu-like symptoms (headaches, dizziness, nausea, etc.) |
| Exposure to high levels of CO over a short period of time | Serious health issues (brain damage, heart and respiratory problems, etc.) |
| Exposure to extremely high levels of CO | Death |
Types of candles that emit carbon monoxide
Candles have been used for centuries for decorative, religious, and practical purposes. However, many people are unaware that certain types of candles can emit harmful chemicals such as carbon monoxide. The following are some of the candles that emit carbon monoxide:
- Paraffin candles – Paraffin is a petroleum by-product that is used to make many commercial candles. When burned, it releases toxic chemicals such as benzene and toluene, as well as carbon monoxide.
- Beeswax candles – Beeswax candles are often marketed as a natural, eco-friendly alternative to paraffin candles. While they are less toxic than paraffin candles, they can still emit small amounts of carbon monoxide when burned.
- Soy candles – Soy candles are made from soybean oil and are often marketed as a more environmentally-friendly option. While they are generally less toxic than paraffin candles, they can still emit small amounts of carbon monoxide.
It is important to note that the amount of carbon monoxide emitted by these candles is generally considered to be low and not harmful to most people, unless burned in large quantities in an enclosed space. However, individuals with respiratory issues, such as asthma, should be cautious when burning any type of candle.
The Root Cause of Carbon Monoxide Emission in Candles
Despite their comforting glow and delightful scent, candles tend to emit carbon monoxide (CO) when burned. In fact, studies show that CO concentrations can be as high as 15 ppm for six hours after lighting a few candles in a room. The root causes of CO emissions in candles are mainly due to:
Candle Composition
- The type of wax used. Paraffin wax tends to produce more CO when burned compared to natural waxes like beeswax, soy wax, and palm wax.
- Fragrances and dyes used. These can also contribute to the CO emissions, as they contain chemicals that release more toxic gases.
- The wick material used. Wicks made from lead, zinc, and other metals will produce higher levels of CO as they contain additives that help them stand upright. Cotton and wooden wicks don’t tend to emit as much CO.
Lack of Ventilation
In addition to the composition of the candle, lack of ventilation is another major cause of CO emissions. When candles are burned in an enclosed space, the combustion process creates CO and other toxic gases, which can accumulate in the room. Poor ventilation inhibits the exchange of clean air, leading to high levels of CO and other pollutants that can be destructive to human health.
Health Risks
When candles are burned, the release of CO can cause adverse health effects, particularly in individuals with heart or respiratory problems. Prolonged exposure to CO emissions can lead to headaches, nausea, dizziness, and in severe cases, even death. Therefore, it’s essential to be vigilant when using candles and ensure proper ventilation in the room to minimize the risks of CO exposure.
Candle Type and Recommended Use
If you want to minimize the risks of CO emissions from candles, you should consider using natural wax candles, like beeswax or soy wax, which produce less CO compared to paraffin wax candles. Additionally, it’s essential to ensure proper ventilation by opening windows and doors when burning candles indoors. Finally, you mustn’t leave candles unattended and should always keep them away from flammable objects like curtains, paper, and timber.
| Candle Type | CO Produced per Hour (ppm) |
|---|---|
