What are the two primary classifications of hazardous materials?

The classification of hazardous materials is critical for understanding their potential impacts on health, safety, and the environment. Among the options provided, the distinction between flammable and non-flammable materials is significant.

Hazardous materials are often classified based on their physical and chemical properties, particularly those that influence their reactivity and danger in various environments. Flammable materials pose a risk because they can ignite easily and pose a fire hazard. This group includes a variety of substances, including certain liquids, gases, and solids that can catch fire. Non-flammable materials, on the other hand, do not ignite under normal conditions and thus present a different level of risk.

Other classifications, like biohazardous and non-biohazardous, focus on biological risks; solid and liquid classifications address physical states; while acidic and basic classifications pertain to pH levels, which are important for corrosive materials but do not cover the broader scope of hazardous materials effectively. Understanding the primary classification of hazardous materials as flammable and non-flammable aids in proper handling, storage, and response protocols to minimize risks and ensure safety during hazardous material incidents.
