Which of the following is a type of hazardous material?

A type of hazardous material is classified as flammable. Flammable materials are substances that can easily ignite and catch fire when exposed to heat or flames. This characteristic poses significant risks during storage, handling, and transportation, making it vital for first responders and hazmat teams to recognize and properly manage flammable materials to prevent fires and explosions.

Understanding that flammable substances are part of the hazardous materials category is crucial for safety protocols and emergency responses in hazardous situations. The classification helps in determining the necessary precautions and procedures that need to be taken to mitigate risks associated with their presence.

On the other hand, the other options such as inconvenient, common, and non-hazardous do not represent types of hazardous materials. Instead, they describe situations or characteristics that do not inherently carry the risks associated with hazardous substances.
