Flammability Limits

Flammability limits define the concentration range of a gas or vapor in the air within which it can ignite if there's a spark or flame. The lower limit is the minimum amount needed to support combustion, while the upper limit is the maximum amount beyond which the mixture becomes too rich to ignite. These limits help determine safe handling and storage of flammable substances, ensuring they are kept outside these ranges to prevent fires or explosions. Understanding these limits is essential for safety in industrial processes, laboratories, and everyday environments where flammable materials are used.
