Hazardous Material Information

Proper handling and disposal of hazardous materials protect our health and environment. 

Why is it Important?

  • Storing hazardous chemicals and materials in your home or garage puts you, your family, and your neighborhood at risk.
  • It is important to minimize this risk by properly using, storing, and recycling these materials.
