Household hazardous waste is any material discarded from homes which may threaten human health or the environment when disposed of improperly when they can no longer be used for their intended purposes. It is illegal to throw hazardous materials in the trash. The City of Fontana provides the opportunity for residents to safely dispose of products containing harmful chemicals. Check containers for key words such as danger, caution, warning, poison, corrosive, flammable, explosive, oxidizer, irritant, harmful, and fatal. Instead, take them to the City of Fontana's Household Hazardous Waste collection facility.
