While it has a high flashpoint of about 600 degrees Fahrenheit (315 degrees Celsius), it can catch fire and burn fiercely below a temperature of 199.4°F (93°C) and it can ignite at a temperature of 450°F (232°C) when it starts smoking.
Additionally, vegetable oil is prone to spontaneous combustion if left on rags.
Therefore, it is important to take precautions and handle vegetable oil with care to prevent fire outbreaks.
Quick Tips and Facts:
1. Vegetable oil is indeed flammable, but it has a higher flammability temperature compared to other cooking oils. It typically requires a higher temperature, around 600°F (316°C), for it to catch fire.
2. The flash point of vegetable oil, which is the temperature at which it can ignite when exposed to an open flame, is approximately 600°F (316°C). This means that if you accidentally drop a lit match into a container filled with vegetable oil, it may not immediately catch fire.
3. The flammability of vegetable oil can increase when it’s heated for a prolonged period of time. If left unattended on high heat for an extended period, vegetable oil can reach its autoignition temperature, which is around 700°F (371°C), and ignite spontaneously.
4. When vegetable oil reaches its autoignition temperature and catches fire, it can release a considerable amount of heat energy. This can result in an intense and potentially dangerous fire, particularly if the vegetable oil comes into contact with other flammable materials.
5. Using a deep fryer with a thermostat control can help prevent vegetable oil from reaching its autoignition temperature. The thermostat allows the fryer to maintain a consistent temperature and helps prevent overheating, reducing the risk of a fire caused by vegetable oil.
Vegetable Oil Flashpoint And Flammability
Vegetable oil is commonly used in cooking, but its flammability is not straightforward. The flammability of vegetable oil depends on its flashpoint, which refers to the temperature at which a liquid emits vapors that can ignite when exposed to an open flame or spark. For vegetable oil, the flashpoint is relatively high, around 600 degrees Fahrenheit (315 degrees Celsius).
Different types of vegetable oils may have varying levels of flammability due to slight differences in their chemical composition. The flashpoints of various vegetable oils range from 600° to 650°F (315° to 320°C), which means that vegetable oil is not considered flammable at its flashpoint. However, it is important to note that vegetable oil can catch fire and burn fiercely at temperatures below its flashpoint.
When vegetable oil is heated beyond its smoke point, which is around 450°F (232°C), it starts smoking. This smoking point is an indication that the oil is close to its flashpoint and can be ignited under certain conditions. Therefore, it is crucial to exercise caution when working with heated vegetable oil to prevent accidental fires.

Understanding The Importance Of Flashpoint For Vegetable Oils
The flashpoint of vegetable oil plays a significant role in determining its level of flammability. At the flashpoint, a liquid releases vapor that can ignite when exposed to a source of ignition, such as an open flame or spark. However, even though vegetable oil may not be considered flammable at its flashpoint of 600 degrees Fahrenheit, it can still burn and be ignited when exposed to higher temperatures.
Vegetable oil has an auto-ignition point between 400 to 435 degrees Fahrenheit, meaning that it can ignite spontaneously within this temperature range without the need for an external source of ignition. This auto-ignition point serves as a warning sign that vegetable oil should be handled with care when exposed to high temperatures.
Although the Occupational Safety and Health Administration (OSHA) does not classify vegetable oil as flammable, it is important to note that it can still pose a fire hazard if not handled properly. Understanding the flashpoint and auto-ignition point of vegetable oil is crucial for ensuring safety when cooking with this common ingredient.
The Risks Of Heating Vegetable Oil Beyond Its Smoke Point
One of the risks associated with heating vegetable oil beyond its smoke point is the release of free radicals. When vegetable oil is heated to high temperatures, it can break down and release unstable molecules that can damage cells when consumed.
Additionally, heating vegetable oil beyond its smoke point can alter the taste and smell of the food being cooked.
Furthermore, as the temperature of vegetable oil increases, so does the risk of it catching fire. Boiling vegetable oil should be avoided, as it can quickly reach temperatures above its flashpoint and become highly flammable. It is essential to dial back the flame and maintain a safe cooking temperature to prevent accidents and reduce the risk of kitchen fires.
