Keep Nebraska Beautiful: Household Hazardous WasteHazardous chemical products can be found in almost every home in Nebraska. Such products include antifreeze, bug spray, glue, motor oil, and solvents. A substance is labeled as hazardous if it can catch fire, if it will react or explode when mixed with other substances, or if it is corrosive or toxic. Take a look around your home or garage and you'll find many hazardous substances. They may seem harmless sitting on the shelf or being used properly, but they can be harmful to humans, our pets, the land in which we grow our food, and the water for drinking and bathing.
