1 University of Manitoba WHMIS Revised November 2011
2 Workplace Hazardous Materials Information System WHMIS Stands for…Workplace Hazardous Materials Information System
3 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.
4 WHMIS has 3 Main PartsLabels – provide information about the hazards of the productMaterial Safety Data Sheets (MSDS) – provide further detailed informationEducation – how to use the information provided
5 The GOAL is… Identify 6 Classes of Controlled Products Understand the Main Hazards associated with each classRecognize and understand the two types of WHMIS labelsUnderstand how to use Material Safety Data Sheets
6 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.
7 WHMIS Does Not ApplyWhen 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 woodTobacco or a product made of tobaccoA manufactured item that will not release chemicalsProducts transported under the Transportation of Dangerous Goods Act – for more information regarding TDG:
8 WHMIS Does Not Apply WHMIS does not apply to products covered by: Explosives ActFood and Drugs ActPest Control Products ActCertain products in the Hazardous Products ActNuclear Safety and Control Act
9 WHMIS Applies for WHMIS labels and MSDS are still required for: Mixtures of radioactive nuclide(s) and a non-radioactive carrier material where:The carrier material is greater than 1.0 ml / 1 gThe carrier material poses a carcinogenic, toxic, reactive, or infectious hazardFor more information regarding Radiation Safety:
10 Hazard Classes & Symbols There are 6 Hazard Classes

46 Hazardous Waste Disposal Procedures The University has well established guidelines and procedures to deal with hazardous waste disposalEHSO provides hazardous waste disposal services at no charge to the University faculties and departmentsIncorporate waste disposal into lab procedures or experimentsNO disposal of Hazardous Waste is permitted down the drain or regular trash canRemember that your end point is someone’s starting point Refer to the EHSO webpage for details
47 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 555Minor spills should be cleaned up by trained staffSpills must never be cleaned up by untrained staffUnder no circumstance shall caretakers be instructed to clean up any lab spillsThe best time to learn about and practice cleaning up a spill is before it happens – read the MSDSEHSO 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
48 Chemical Storage General Chemical Organization Organize by compatibility not alphabeticallySeparate each compatible groupIn separate cabinets or on separate shelvesOr in secondary containers in same cabinet or shelfMake sure all containers are properly closedContainers must be labeled and tightly capped
49 Chemical Storage General Chemical Organization Flammables Store in flammable storage cabinetsBasesStore separatelyOxidizersAcidsStore in corrosive resistant acid cabinetEXCEPT: chromic, nitric, and perchloric acids which should be stored separatelyGlacial acetic acid should be stored as a flammable
50 Chemical Storage Potentially Explosive Chemicals Picric Acid and Nitro CompoundsDry picric acid may explode if subjected to heat, shock, or friction (opening the lid)Picric acid must be stored under wet.Some nitro compounds may have similar requirementsPeroxide Forming CompoundsExample ethers, dioxanes, sodium amidePeroxide formation may be initiated by light or airPeroxides are prone to explosive decomposition when subjected to heat, shock, or friction (opening the lid)Evaluate the conditions of these chemicals regularlyRefer to MSDS for storage and handling requirements
