Some cities and communities in Florida sponsor either occasional or permanent hazardous waste collection program. Most household chemical products and pesticides sold in the United States have warning labels. These labels tell us whether the product is flammable, poisonous, corrosive or explosive. The labels usually also give first aid instructions. Read the label to find out how to use the product safely and what precautions to take for its disposal.
