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. Charcoal lighter fluid, gasoline, kerosene, nail polish remover and various oils are examples.
Reactive wastes can react with air, water or other substances to cause rapid heating or explosions.
Acids that heat up rapidly and spatter when mixed with water are examples. EPA estimates that the average household disposes of 1 pound of hazardous waste each year. In North Carolina that means that 2,045,700 pounds of hazardous household wastes must be handled properly each year. Most household products are not harmful if used according to label directions. However, they can become harmful if you use them improperly, store them improperly, or dispose of them improperly.
