The term "Flash Point" refers to the lowest temperature at which a liquid can form an ignitable mixture in air. It is a critical property in assessing the flammability of substances, particularly in industries dealing with chemicals and fuels. Knowing the flash point helps in ensuring safety during storage, handling, and transportation of flammable materials. Flash points are categorized into three classes: low, moderate, and high. For example, substances with a low flash point, like gasoline, can ignite easily at room temperature, while those with a high flash point, such as vegetable oil, require much higher temperatures to ignite. Understanding flash points is essential for preventing fire hazards.
