Dangerous goods are materials or items that can pose a risk to health, safety, property, or the environment. These goods can be flammable, explosive, toxic, or corrosive, and they require special handling and transportation procedures to prevent accidents. Examples include chemicals, batteries, and flammable liquids. Regulations for dangerous goods are established by organizations such as the United Nations and various national agencies. These regulations ensure that dangerous goods are properly classified, labeled, and packaged to minimize risks during storage and transport. Compliance with these rules is essential for protecting people and the environment.
