"Hazmat" stands for hazardous materials, which are substances that can pose a risk to health, safety, or the environment. These materials can be in solid, liquid, or gas form and may include chemicals, biological agents, or radioactive materials. Proper handling, storage, and disposal of hazmat are essential to prevent accidents and protect people and ecosystems. Hazmat regulations are enforced by agencies like the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA). These regulations ensure that businesses and individuals follow safety protocols when dealing with hazardous materials, including labeling, training, and emergency response procedures.
