Chemically loaded and bio-hazardous wastes can be dangerous to private and public sewer systems and hazardous to people.
The treatment of corrosive and acid waste is mandated by this Code.
The treatment of chemically loaded effluents is usually regulated by sewage collecting and treatment authorities. The treatment of bio-hazardous waste should follow good engineering practice, such as that described in the Laboratory Biosafety Guidelines published by Health Canada. Bio-hazardous waste disposal systems require specific engineering expertise and remain outside the scope of this Code.
