WHMIS Stands for…

WorkplaceHazardousMaterialsInformationSystem

whmis is
WHMIS is…

The Workplace Hazardous Materials Information System is a Canada-wide system designed to give employers and workers information about hazardous materials used in the workplace.

WHMIS standards are coordinated between both Federal and Provincial governments.

Manitoba Workplace Safety and Health Act and Regulations sets the WHMIS requirements.

whmis has 3 main parts
WHMIS has 3 Main Parts
  • Labels – provide information about the hazards of the product
  • Material Safety Data Sheets (MSDS) – provide further detailed information
  • Education – how to use the information provided
slide5

The GOAL is…

  • Identify 6 Classes of Controlled Products
  • Understand the Main Hazards associated with each class
  • Recognize and understand the two types of WHMIS labels
  • Understand how to use Material Safety Data Sheets
a controlled product is
A Controlled Product is…

A Controlled Product is any substance or material which meets any of the criteria for inclusion in one or more of the six WHMIS Hazard Classes as defined in the Federal Controlled Product Regulation.

Under WHMIS , there is no comprehensive list of controlled products but only a list of hazard criteria.

slide7

WHMIS Does Not Apply

    • When WHMIS does not apply there may be another Act or regulation that does.

WHMIS does not apply to controlled products that are:

  • Wood or a product made of wood
  • Tobacco or a product made of tobacco
  • A manufactured item that will not release chemicals
  • Products transported under the Transportation of Dangerous Goods Act – for more information regarding TDG:

Hazardous Waste Disposal Procedures

  • The University has well established guidelines and procedures to deal with hazardous waste disposal
  • EHSO provides hazardous waste disposal services at no charge to the University faculties and departments
  • Incorporate waste disposal into lab procedures or experiments
  • NO disposal of Hazardous Waste is permitted down the drain or regular trash can
  • Remember that your end point is someone’s starting pointRefer to the EHSO webpage for details
slide47

Spill Clean-up

Chemical, Radiological, or Biological

  • If a spill occurs that poses an immediate risk to people, or if someone is injured – it is an EMERGENCY – call 555
  • Minor spills should be cleaned up by trained staff
  • Spills mustnever be cleaned up by untrained staff
  • Under no circumstance shall caretakers be instructed to clean up any lab spills
  • The best time to learn about and practice cleaning up a spill is before it happens – read the MSDS
  • EHSO is also available to assist with the cleanup of “non-emergency” spills beyond the capabilities of available staff Information on spills cleanup can be found on the EHSO website
slide48

Chemical Storage

General Chemical Organization

  • Organize by compatibility not alphabetically
  • Separate each compatible group
    • In separate cabinets or on separate shelves
    • Or in secondary containers in same cabinet or shelf
  • Make sure all containers are properly closed
  • Containers must be labeled and tightly capped

Chemical Storage

Potentially Explosive Chemicals

  • Picric Acid and Nitro Compounds
