While most people use vegetable oil for cooking, others prefer olive oil as it is superb for many kinds of food and gives the taste of the Mediterranean.

Are you considering olive oil for cooking but wondering if it is flammable? Here’s what you should know.

Is olive oil flammable? 

Is olive oil flammable

Olive oil is not flammable but can catch fire if exposed to high heat or naked fire. However, it does not catch fire easily because it takes longer to ignite when exposed to heat. The olive oil has to first be heated to its flash point or smoke point before it can ignite and burn.

That pure olive oil can catch fire and, at certain levels, will combust on its own does not make it flammable. Flammable liquids can easily ignite in air at ambient temperatures.

According to the Occupational Safety and Health Administration (OSHA) of the United States Department of Labor, a liquid is flammable if it has a flash point at or below 199.4 degrees Fahrenheit. Olive oil has a flash point above 400 degrees Fahrenheit and is not classified as flammable under class A of flammable liquids.

A flash point is a temperature at which oil can create flammable vapors and cause a fire if exposed to heat. The flash point of olive oil is 410 Fahrenheit, but it can be lower for some varieties, like extra virgin olive oil.

Technically, when olive oil is put on high heat, it shows signs of overheating before it reaches flammable levels. However, you can hasten its flash point or smoke point level if you spray a fine mist while heating it.

Olive oil is a great cooking oil that is used for different foods. It also has significant health benefits. But like most cooking oils, it also proves a fire risk. Olive oil can catch fire; when it does, it lasts for a long time in a self-sustaining manner.

Some even use it as lamp improvisations. So you should apply certain precautions while using it, like avoiding substances that can stir its flammability when heated.

Olive oil can become more flammable when you turn it into a fine mist and put it in a spray bottle. These particles are more oxygen-exposed and require lower temperatures to ignite or burn.

Does olive oil catch fire? 

Yes. Olive oil catches fire and can burn for a long time when it reaches its flash point or smoke point. This is because of the hydrocarbon chains present in the molecules of the oil. In ancient history, some churches used olive oil as fuel for their lamps.

Once Olive oil reaches its flash point temperature, achieved through high heat or naked flame, it will catch fire. Though Olive oil is not flammable, it catches fire and can self-sustain it for a long time. Watch this video to see how olive oil can catch fire.

Can olive oil catch fire in an air fryer? 

Most cooking oils can catch fire when used in air fryers, especially coconut oil. So, a cooking oil that stands up to a higher temperature is essential.

While olive oil will not catch fire in an air fryer, it would cause serious smoking. However, if more olive oil is present in the fryer and goes beyond the smoking point, it will catch fire.

Especially the extra virgin olive oil, which has a smoke point of 375-405 degrees Fahrenheit, lower than other olive oils. Using olive oil in an air fryer oven is usually not advisable.

This is because air fryers cook food quickly at high temperatures, which also causes the oil to smoke quickly.

For olive oil to catch fire, it has to reach its flash point, which is at a high temperature. Therefore, oils like extra virgin olive oil are not so safe for air frying.

Though extra virgin olive oil has a lower smoke point and can smoke easily when used in an air fryer, an extra light olive oil may work better in an air fryer.

What temperature does olive oil light on fire?

Olive oil will light on fire at a flash point of 410 degrees Fahrenheit. It can also catch fire at a smoking point of 375 – 405 degrees Fahrenheit and its auto-ignition point of 815 degrees Fahrenheit.

Is olive oil safe to burn?

Yes. Olive oil is safe to burn as long as it does not come in contact with substances like fine mist that triggers combustion and cause flames when olive oil is being heated.

This cooking oil is not a volatile liquid; therefore, it takes a long time to catch fire or burn. For this reason, it serves as fuel for your lamp for most people. See how to make a manual lamp using olive oil. 

Does olive oil burn when cooking?

Olive oil will burn only when it reaches its flash point or smoke point, which happens when it is heated at high temperatures. It can also burn if you apply fine mists to the oil.

Final Recommendations.

That Olive oil is not flammable does not make it less of a fire risk, especially in a working kitchen. In situations where you experience a blaze from the olive oil and you intend to extinguish it, here are the standard protocols to follow.

  • Before fighting a fire, ensure the fire is small and contained. You have a means of escape, and you are safe from toxic smoke. If you have considered these and your instincts tell you it is okay to put out the fire, move to the next step.
  • Activate the building alarm system or notify 911. If you can’t, ensure you get someone to do it.
  • Assist any person in immediate danger to exit the building and try not to put yourself at risk.
  • Use the fire extinguisher only after you have activated the fire alarm and anyone in immediate danger out of the building.

Before using a fire extinguisher, be sure it is a wet chemical fire extinguisher. Not all extinguishers are used to put out cooking fire hazards. This applies to both Olive oil and other cooking oil fires.
