What is defined as any material that may pose a substantial hazard to human health or property?

Hazardous material, commonly referred to as HAZMAT, is defined as any substance that poses a considerable risk to human health or the environment. This definition encompasses a broad range of materials that could be dangerous when they are improperly handled, stored, transported, or disposed of.

In many regulations and guidelines, HAZMAT is categorized based on its potential to cause harm—this includes explosive materials, flammable liquids, corrosive substances, and toxic chemicals. The emphasis on any material that "may pose a substantial hazard" covers a variety of situations, thereby making it a comprehensive designation that applies to various contexts, from industrial settings to emergencies.

Understanding hazardous materials is crucial for ensuring safety in aviation and other industries, where materials need to be managed carefully to prevent accidents and protect not only workers but also the public and the environment.
