Chemical Waste Collection & Disposal Procedure

This procedure describes how chemical waste at the University of Windsor is handled at the point of generation and its collection through the Chemical Control Centre (CCC).  This procedure applies to all personnel at the University of Windsor who generate chemical waste.  It does not include the disposal of biohazardous or radioactive wastes.  


Procedure

It is essential to have a collection system in place prior to generating any waste.  This includes proper segregation, chosing appropriate containers, labeling, storage, and final disposal through the CCC.  

Segregation

  • Before starting any experiment, determine the types of wastes that will be generated.  Wastes are generally segregated based on hazard class (e.g. flammable, corrosive, toxic, oxidizing) and compatibility.
  • These are further segregated based on chemical composition; organic from inorganic, oxidizing acids from non-oxidizing acids, and halogenated solvents from non-halogenated solvents.
  • Refer to the Hazardous Waste Disposal Guide for a detailed list of wastes streams requiring segregation and contact the Hazardous Materials Technician (HMT) for further assistance as required.

Containers & Labeling

  • Use only waste containers provided by the CCC.
  • Containers must be compatible with the type of material being added.
  • Containers must be in good condition and lids/caps closed tightly when not in use.
  • Containers must have a yellow “Hazardous Waste” tag, or equivalent, attached.
  • As soon as a container is put into use, fill out contact information, start date, and contents.  Use chemical names with approximate concentrations (>1%).  No formulas or short forms.
  • Do not fill containers more than ¾ full.
  • Surplus chemicals for disposal should remain in their original container; additional labeling is not required if the manufacturer or workplace label is intact.

Storage & Handling

  • Store liquid waste in a secondary container large enough to contain any spill.
  • Store according to compatibility.  Do not store incompatible material in the same secondary container.
  • Regularly inspect temporary waste accumulation areas.
  • Do not store for more than 90 days, even if the container is not full.
  • Proper personal protection is always required when handling and transporting hazardous waste.
  • Always use a spill proof cart or secondary container to transport waste within a building.
  • Use a freight or chemical elevator to transport waste between floors, never a passenger elevator.

Laboratory Representatives

While it is the responsibility of all personnel to observe proper waste handling procedures in the course of their work, Supervisors, Principal Investigators, or delegates should designate a Representative to oversee final disposal through the CCC.  This Representative should be an experienced, technician, postdoctoral fellow or graduate student, and never an undergraduate student.

The Representative will work with the HMT to ensure that collection systems are in place which meet the individual needs of their group, regularly inspect and arrange for disposal through the CCC, and ensure that all group members are made aware of these collection and disposal procedures.


Departmental Disposal Procedures

Essex Hall

  • The Laboratory Safety, or otherwise designated, Representative shall contact the HMT at ccc@uwindsor.ca or phone ext. 3519 to provide an inventory of the types and quantity of waste for disposal and will ensure that all labels are complete.
  • Waste is typically picked up from the labs on Fridays by the HMT.  Please plan ahead and submit requests by end-of-day on Thursday.  Alternate days may be arranged upon request.
  • Full containers are exchanged with empties and any additional containers will be provided upon request. 
  • Direct delivery to the CCC by approved personnel (Representatives, Supervisors, or Staff) may be accommodated with prior consent only.  Again, individuals must observe all safety measures when transporting waste.

Biology Building

  • The satellite waste accumulation site is located in the Biology Stock Room, 316.
  • Deliver waste in person to a Stock Room Technician during hours of operation only. 
  • Never deposit waste after hours or without the consent of a Technician.
  • Ensure containers and labels are properly prepared prior to transport and disposal.
  • Observe all safety measures when transporting waste within the building.
  • Additional waste supplies are available from the Biology Stock Room.
  • For disposal of non-standard/special waste items, please contact the HMT at ccc@uwindsor.ca or phone ext. 3519.  

Centre for Engineering Innovation (CEI)

  • The satellite waste accumulation site is located in Room 1197 CEI.
  • Contact Mr. Bill Middleton at bmiddleton@uwindsor.ca or ext. 2564 to schedule a delivery time and obtain additional waste supplies.  In his absence, please contact the HMT directly at ccc@uwindsor.ca or phone ext. 3519.
  • All deliveries must be made in person and with prior consent. 
  • Ensure containers and labels are properly prepared prior to transport and disposal.
  • Observe all safety measures when transporting waste within the building.
  • For disposal of non-standard/special waste items, please contact the HMT.

Great Lakes Institute (GLIER)

  • The satellite waste accumulation site is located in the Lab Services Room, 127.
  • Place waste containers in the designated areas: non-flammable waste in a secondary container (bin) on the shelf, flammables in the flammable cabinet, and large solid waste containers to the side of the shelf against the wall.
  • Ensure containers and labels are properly prepared prior to transport and disposal.
  • Observe all safety measures when transporting waste within the building.
  • Obtain replacement supplies from the shelf as needed.  Contact the HMT for any additional supplies. 
  • For disposal of non-standard/special waste items, please contact the HMT at ccc@uwindsor.ca or phone ext. 3519.

All Other Buildings (CARE, HK, SoCA, Memorial, etc.)

Contact the HMT at ccc@uwindsor.ca or phone ext. 3519 to schedule a waste pick-up and obtain waste supplies.
