What kind of material is characterized as "reactive"?

A material characterized as "reactive" is one that can undergo violent chemical changes. Reactive materials have the potential to engage in chemical reactions that can release energy in the form of heat, light, or even gas, which may lead to hazards such as explosions or toxic gas release. These materials can react vigorously with other substances, including water, air, or other chemicals, often leading to unexpected and dangerous outcomes.

Understanding reactivity is crucial for hazardous materials management because it informs the handling, storage, and emergency response strategies required to mitigate risks associated with such materials. Recognizing the nature of reactive substances is essential for ensuring safety in environments where chemicals are used or stored.
