What is the classification of flammable liquids in HAZMAT?

Flammable liquids are classified as Class 3 in HAZMAT regulations. This classification includes liquids that can ignite and sustain combustion at relatively low temperatures, specifically those with a flashpoint of 100 degrees Fahrenheit (37.8 degrees Celsius) or lower. Class 3 materials pose significant risks during emergencies due to their volatility and potential to create explosive atmospheres when combined with air, making proper handling and storage critical for safety. Understanding the classifications helps responders identify the hazards associated with various materials and take appropriate action in emergency situations.
