Household Hazardous Waste Hazardous waste in our house?! • We all use many solvents and solutions at home because they help with cleaning, polishing, painting, and other activities. • These hazardous products often need special handling and storage because they are dangerous to human health or to the environment. Government Regulations • Governments require that hazardous household materials be marked with warning symbols that indicate why, and to what degree, a product is dangerous. Symbols • Poison: Explosive: • Flammable: Corrosive: Degree of Danger • Caution: The lowest degree of danger. Marked with a yellow triangle with the symbol inside. • Warning: The next level of danger. Marked with an orange diamond with the symbol inside. • Danger: The highest degree of danger. Marked with a red octagon. WHMIS • WHMIS stands for the Workplace Hazardous Materials Information System. • WHMIS consists of 8 different symbols that each have different meanings. Why is WHMIS Important? • WHMIS is a provincial legislative response to provincial employees' and employers' rights to know about the safety and health hazards of the materials they use in the workplace Three Components of WHMIS ‣ Labels: Applied to containers of hazardous materials. The labels alert the user to the dangers of the product and to the essential precautions for its safe use. ‣ Material Safety Data Sheets (MSDS): Prepared by the product supplier and supplied to the user. These sheets provide detailed information about product composition, reactivity, health effects, protective equipment and procedures, and emergency procedures. ‣ Education and Training related to hazards and associated safe work procedures is mandatory for those either working with or working in the proximity of the controlled product. Meaning of Symbols • OXIDIZING MATERIAL: Promotes and supports the building of fire. • • BIOHAZARDOUS INFECTIOUS MATERIAL: Toxins that have been shown to cause disease or are believed to cause diseases in either animals or humans. • MATERIALS CAUSING IMMEDIATE & SERIOUS TOXIC EFFECTS: Materials if ingested will make you very ill and may cause death. • COMPRESSED GAS: A compressed gas cylinder is usually quite heavy and when ruptured can become a projectile with the potential to cause significant damage. • CORROSIVE MATERIAL: Corrosive materials can attack metals or cause permanent damage to human tissues such as the skin and eyes on contact. Can cause burning, scarring, blindness. • DANGEROUSLY REACTIVE MATERIAL: They may react violently under conditions of shock or an increase in temperature. • FLAMMABLE AND COMBUSTIBLE MATERIAL: Will ignite and continue to burn if around a flame. • • MATERIALS CAUSING OTHER TOXIC EFFECTS: Materials they may cause cancer, irritations of the respiratory and digestive system.
