A flammable liquid is characterized by having a flashpoint of what temperature?

A flammable liquid is defined as a substance that has a flashpoint of below 100 degrees Fahrenheit. The flashpoint is the lowest temperature at which enough vapor is present to ignite when exposed to a flame or spark. Liquids with a flashpoint below this threshold can easily ignite in normal atmospheric conditions, making them particularly hazardous in a fire situation.

When considering flashpoints, liquids that have a flashpoint above 100 degrees Fahrenheit are generally classified as combustible rather than flammable. Hence, the key distinction lies in the flashpoint measurement, with values below 100 degrees Fahrenheit indicating a greater potential for ignition. This classification is crucial for firefighters and safety professionals when assessing the risks associated with handling and storing various liquids. Understanding this concept is vital for ensuring safety protocols are followed to minimize fire hazards.
