Hazardous materials are substances that can pose a risk to health, safety, or the environment. These materials can be chemical, biological, or radiological in nature and may cause harm through exposure, ingestion, or environmental contamination. Common examples include toxic chemicals, flammable liquids, and infectious agents. Proper handling, storage, and disposal of hazardous materials are essential to prevent accidents and protect public health. Regulations often govern the management of these substances, ensuring that individuals and organizations follow safety protocols. Awareness and training are crucial for those who work with or around hazardous materials to minimize risks.
