When you care for yourself, your home, your yard and your garden you use a variety of chemical products. Many of these common household products contain hazardous chemicals. When we no longer want these products they become hazardous waste. Corrosive wastes can cause a chemical action that eats away materials or living tissue.
Battery acid is an example.
Toxic wastes can cause illness or death. Some are more dangerous than others. Exposure to a small concentration of a highly toxic chemical may cause symptoms of poisoning. Pesticides, cleaning products, paints, photographic supplies and many art supplies are examples. Ignitable wastes can catch fire spontaneously or burn easily.
