HAZMAT Boots are made for Hazardous Material

A hazardous material ( Hazmat or HAZMAT ) is any solid, liquid, or gas that can harm people, other living organisms, property, or the environment. The term hazardous material is used in this context almost exclusively in the United States. The equivalent term in the rest of the English-speaking world is Dangerous Goods. A hazardous material may be radioactive, flammable, explosive, toxic, corrosive, biohazardous, an oxidizer, an asphyxiant, an allergen, or may have other characteristics that make it hazardous in specific circumstances.
Mitigating the risks associated with hazardous materials may require the application of safety precautions during their transport, use, storage and disposal. Most countries regulate hazardous materials by law, and they are subject to several international treaties as well.
Persons who handle hazardous materials will often wear protective equipment, and metropolitan fire departments often have a "Hazmat team" specifically trained to deal with accidents and spills. These teams train at a variety of specialized locations.
Laws and regulations on the use and handling of hazardous materials may differ depending on the activity and status of the material. For example one set of requirements may apply to their use in the workplace while a different requirements may apply to spill response, sale for consumer use, or transportation. Most countries regulate some aspect of hazardous materials.
The most widely applied regulatory scheme is that for the transportation of hazardous materials. The Committee of Experts on the Transport of Dangerous Goods of the United Nations Economic and Social Council issues a Model Regulation on the Transportation of Dangerous Goods. Most regional and national regulatory schemes for hazardous materials are harmonized to a greater or lesser degree with the UN Model Regulation. For instance, the International Civil Aviation Organization has developed regulations for air transport of hazardous materials that are based upon the UN Model but modified to accommodate unique aspects of air transport. Individual airline and governmental requirements are incorporated with this by the International Air Transport Association to produce the widely used IATA Dangerous Goods Regulations. Similarly, the International Maritime Organization has developed the IMO Dangerous Goods Regulations for transportation on the high seas. Many individual nations have also structured their hazardous materials transportation regulations to harmonize with the UN Model in organization as well as in specific requirements.
