Flammable substances are classified based on their flash point, which is the lowest temperature at which they can form an ignitable mixture in air. These classifications include:
- Extremely Flammable: Substances with a flash point below 0°C. - Highly Flammable: Substances with a flash point below 21°C. - Flammable: Substances with a flash point between 21°C and 55°C.
Understanding these classifications helps in determining the appropriate safety measures and handling procedures.
