In accordance with Section 7.4(5)(b) of The Workplace Safety and Health Act requires employers to have a system to identify and control hazards.

In Hanover School Division the control system has a process in place to:

  • Through a comprehensive housekeeping and inspection schedules, teachers / instructors who are in charge of a class are responsible for pre and post – inspections of their  shop, kitchen, or all, to look for known and potential dangers to workers, and enable workers to bring forward concerns about hazards;
  • A complete Job Hazard Analysis of all potential hazards that may occur in the shop or worksite areas (shops, labs, construction sites, etc.) is done and a corresponding Safe Work Procedure developed for each job to eliminate or control the hazard(s).

These measures may include redesigning a work process, substituting a safe chemical for a hazardous one, buying new equipment, or using other controls such as machine guards and noise enclosures, etc.

All schools with vocational shops and science labs will develop and maintain up-to-date, safety procedures manual for each area.

Managing Hazardous/Chemical Materials

Activities within the Hanover School Division include the use, storage, and disposal of chemicals. These guidelines are designed to identify, eliminate and/or control chemical hazards.  

These guidelines and procedures apply to all divisional staff that may be required to handle hazardous chemicals.

Terms of Reference

J.H.A. – Job Hazard Analysis
M.S.D.S. – Materials Safety Data Sheet
P.P.E. – Personal Protective Equipment
W.H.M.I.S. – Workplace Hazardous Materials Information Management

Use, Storage and the Safe Disposal of Chemicals

All staff that use, store, or dispose of chemicals must be trained in W.H.M.I.S. and must follow all M.S.D.S. requirements.

Instructions provided on MSDS must be followed including the proper storage of chemicals, the use of controls such as PPE, fume hoods and other engineering controls and disposal instructions.

Handling Chemicals

All division facilities must maintain an up-to-date inventory of chemicals using the division database. Each chemical recorded on that inventory will be provided with an MSDS using the on-line MSDS retrieval system. Staffs that have access to the on-line MSDS database must be trained to use the system and must have access to a computer terminal. Staffs that do not have computer access are able to use the MSDS binders that are located in the general office of each facility.
The WellNet Master Book is the main book in our electronic MSDS management system and contains all of HSD’s Material Safety Data Sheet (MSDS) information.  We are required by law to maintain an updated inventory of all chemicals used within the division along with current MSDS information on each chemical.

Chemicals without a MSDS information sheet are not to be used in HSD.

After the purchase and delivery of new chemicals to a school, schools are required to provide Central Office with the following information, which will be entered into the WellNet system.

  • Manufacturer’s Name
  • Supplier
  • Product Name
  • Product Code
  • MSDS Number (please include a copy of the MSDS sheet provided by the manufacturer with each request)
  • Document Type (see Appendix A)

Procedures for Purchasing Chemicals

  • Purchase the chemical.
  • Complete a HSD – MSDS Request Form (see Appendix B) for each new chemical purchased.
  • Attach a copy of the MSDS sheet provided by the manufacturer to the request form.
  • Submit all information to Esther Enns – who will then update the HSD Master Book.
  • Add the new chemical information to the school’s chemical inventory list – please use red font color to indicate a new chemical purchase.

Annual Inventory Report / Safe Removal of Chemicals

  • In May of each school year, an electronic copy of each school’s chemical inventory (science / vocational labs) will be sent out to each school.
  • Schools are required to review the inventory list and mark / identify any chemicals that they would like to have discarded and removed from their MSDS book.
  • School inventories are to be re-submitted to Esther Enns –  by June 15th of that school year.
  • Miller Environmental Corporation will be contacted and provided with the list of chemicals to be discarded.
  • Schools are asked to make sure all chemicals that have been identified for disposal are clearly marked “DISCARD” and are stored in container sizes of 1 litre or less.
  • Information as to where the chemicals for discard are stored is to be provided / left with the custodian who will make the information available during the summer to Miller Environmental Corporation.
