Hazardous Waste Disposal

The disposal of chemical waste at U.N.B. is coordinated through designated departmental staff trained and certified in the Transportation of Dangerous Goods (TDG). Any questions regarding the disposal of chemical wastes that cannot be answered by trained staff should be directed to the Environmental Health and Safety Office.

The following waste procedures are meant to serve as a guideline for the disposal of hazardous materials. Refer further to provincial and federal regulations for specific information on handling of hazardous waste.


  1. Only hazardous waste generated by the University will be collected for disposal.
  2. Chemical waste must not be flushed down sanitary drains as a method of disposal.
  3. Hazardous materials must not be mixed with regular garbage destined for landfill.
  4. Specialized procedures exist for disposal of radioactive waste and biohazardous waste. Refer to the UNB Radiation Safety Manual or the UNB "Procedures for Biohazardous Waste Disposal", respectively, both of which are available from the Safety Office.
  5. The individual who produced the waste (waste generator) is required to adequately identify and label waste containers prior to acceptance for disposal.
  6. If waste containers have not been adequately identified, the departmental personnel (stores manager or technical support staff) responsible for waste coordination may refuse to accept it and may consult the Safety Office.
  7. Hazardous waste must be made as homogeneous as possible, i.e., avoid unnecessary mixtures if at all possible. Refer to "Liquid Chemical Waste Segregation"; consult "Chemical Code Groups" for compatibility and storage recommendations (attached).
  8. Unidentified chemicals cannot be accepted for disposal. Every means possible, including contacting the individual(s) who may have taken leave from the University, should be employed.
  9. The National Fire Code prohibits unnecessary accumulation of hazardous waste.
  10. Faculty/staff/graduate students planning to take leave from the University must ensure that chemical wastes for which they are responsible are identified for disposal prior to leaving the University.

Scheduling Waste Collection

Pick-up of chemical waste is initiated by completing the Hazardous Waste Disposal Workorder, forwarding it to the waste coordinator in your department (Stores Manager or technical support staff who are TDG certified) for signature of approval who then forwards it to the Safety Office for service.
