Learn some important propane safety information

propane flame kentuckyIf you use propane in your home, you are undoubtedly aware of the many benefits it brings to your quality of life.

Propane is a clean and efficient option for many applications in your home because it is environmentally friendly and cost-effective. You’ll enjoy using a propane range that has instant temperature control and even cooking. Propane is a superior, economical alternative to electricity for heating pools and spas. Propane is also a great choice for fueling grills and fire pits in an outdoor living space.

Propane has a very good safety record due to stringent government regulations and high industry standards. In keeping with best practices, Midwest Gas believes it is important to educate our customers about propane to ensure you feel safe and secure using it in your home. One important safety indicator to learn about is the color of the flame.

What does the blue flame mean?

Propane is colorless before it ignites, but when it burns, it creates a blue flame that is different than other materials that burn, such as wood or oil.

For complete combustion to occur, gas and air need to be mixed in the correct proportions. A blue flame indicates that enough oxygen is available for this type of combustion as molecules of the propane are ionized.

If the propane is burning fully – with complete combustion and a blue flame – it means you’re not wasting any propane.

Why would a propane flame be orange or yellow?

When a propane flame is yellow or orange, it might indicate that the fuel is not being fully combusted. A common example of this is when spilled or burnt food blocks parts of a burner on a gas stovetop

The temperature of a propane flame when it is completely combusted is 3,596˚ Fahrenheit. The temperature of the flame when it’s burning with a yellow flame is 1,832˚. With an improper flame, you’re only getting about half of the heat. That can have a major impact on your cooking. You won’t get a nice sear on your meat, and it will take longer for water to boil. It also decreases efficiency, driving up your propane costs.

What is most alarming is that carbon monoxide can build up in your home if the flames are not blue. Contact a service professional if you detect yellow or orange flames from your propane equipment.
