What is the flash point of a substance?

The minimum temperature at which a substance can explode

The temperature at which a substance ignites spontaneously

The minimum temperature at which a substance gives off enough vapors to support a flame when an ignition source is present

The flash point of a substance is defined as the minimum temperature at which it generates sufficient vapors to form an ignitable mixture with air when an ignition source is present. This definition emphasizes the relationship between vapor generation and the potential for ignition, making it a critical factor in assessing fire hazards associated with chemicals and fuels. Understanding the flash point is essential for safety considerations in storage and handling, as it identifies the threshold at which a material can become a fire risk under specific temperature conditions. This concept is particularly important in industries that involve the use of flammable liquids, as it informs guidelines and regulations to prevent accidents and ensure safe practices.
