What is the focus of UN Hazard Class 3?

The focus of UN Hazard Class 3 is flammable liquids, which are substances that can easily ignite and potentially cause fires and explosions. Flammable liquids are characterized by their flash point, which is the temperature at which they produce enough vapor to ignite in air. Due to their volatile nature, these substances require careful handling, storage, and transportation to prevent accidents and ensure safety.

Classifying flammable liquids under this hazard class allows emergency responders and safety professionals to implement specific protocols and guidelines that address the risks associated with these materials. This includes utilizing appropriate protective equipment, understanding fire behavior, and knowing how to extinguish fires involving flammable liquids.

Understanding the classification of flammable liquids is crucial for those in fire and emergency services as it impacts how incidents involving such materials are approached and managed.
