To outline procedures for the disposal of hazardous waste.  To ensure compliance with the City of Fredericton's Wellfield Protected Area Designation Order (WfPADO).


All University personnel using hazardous materials on both campuses.


A hazardous material is defined as any biological, chemical or physical agent or material exhibiting any of the following characteristics: explosive; compressed gas; flammable; combustible liquid; reactive or oxidizing; toxic or infectious; radioactive; corrosive; and/or environmental hazard.


  • The University is committed to responsible management of hazardous materials in an effort to minimize the risk of exposure to the University community and to prevent contamination of the environment including contamination of the groundwater aquifer situated below the Fredericton campus that provides safe drinking water to the City of Fredericton. The Safety Office is responsible for coordinating the disposal of hazardous materials in accordance with occupational health, safety and environmental regulations.
  • Disposal of hazardous waste shall be coordinated by one Transportation of Dangerous Goods (T.D.G.) trained staff member in each University department which uses chemicals. Inquiries on specific procedures should be directed to T.D.G. staff or the Safety Office.
  • Specific procedures apply to radioactive or biohazardous waste; refer to the Radiation Safety Manual or the "Procedures for Biohazardous Waste Disposal", respectively. Both are available from the Safety Office.
  • Only hazardous waste generated by University operations shall be accepted for disposal. The University is not licensed to accept waste from other sources.
  • Hazardous liquid chemical waste shall not be disposed of via sanitary drains or storm sewers. Solid or liquid hazardous waste shall not be combined with regular garbage.
  • Individuals who generate hazardous waste shall be responsible for proper identification and labelling. Unidentified wastes shall not be accepted for disposal.
  • Waste chemicals shall be stored in an approved chemical storage facility to minimize fire hazard, as well as any environmental health hazards due to spills or leaks.


  1. Users shall complete a Hazardous Waste Disposal Form available from the Safety Office.
  2. Users shall ensure that the material is safely contained and labelled with the original manufacturer supplier label (provided the contents consist only of this chemical) or a Workplace Hazardous Materials Information System (W.H.M.I.S.) label.
  3. Users shall ensure liquid chemical waste is collected in separate containers as follows (chemical shall be compatible with container):
    • organic liquids (high BTU e.g. alcohols, etc.)
    • organic liquids (low BTU e.g. glycols)
    • halogenated liquids (chloroform, etc.)
    • corrosive liquids (sulphuric acid, etc.)
    • machine oils (vacuum pump, compressor, etc.)
    • petroleum oils (heavy fuel oils, gear oils)
    • gasoline
