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.

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.

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:

Class D : Poisonous and InfectiousClass D : Poisonous and Infectious


Class D : Poisonous and InfectiousClass D : Poisonous and InfectiousDivision 1Division 1

Risks Small quantities may be harmful or lethal May be toxic not only if ingested but also if inhaled or absorbed through skin or eyesMany acute toxic compounds act as carcinogens at lower levels

Examples Carbon monoxide All halogens Cyanides



Risks Materials which have harmful effects after repeated exposures or over long periods of time

Damage could include:Permanent injury or deathBirth defectsCancerOrgan damageSensitization and allergies

Examples Asbestos Formaldehyde, benzene Ammonia



Risks Infectious materials which may cause disease resulting in illness or death

Examples Blood, tissue, and body fluids Tissue culture Experimental cultures


Class D : Poisonous and InfectiousClass D : Poisonous and Infectious

Handling and Use Wear protective clothing to avoid all exposures: skin, inhalation, ingestion, and injection Work in a fume hood or BSC Avoid creating dust, vapours, and aerosols Obtain appropriate immunizations Handle exterior containers as though it is contaminated Store and transport securely to prevent accidental spillage


Class E : Corrosive MaterialClass E : Corrosive Material

Risks Will burn human tissue including skin, eyes, nose mouth, throat & lungs Will corrode many lab related materials particularly metals Fumes may damage the environment

Examples Strong acids & bases Hydrogen fluorideHydrogen chloride


Class E : Corrosive MaterialClass E : Corrosive Material

Handling and Use Wear appropriate protective clothing When possible work in the fume hood Open containers slowly When diluting acids, always add acid to water Store in non-corroding containers, on non-corroding trays (secondary containers ) Store away from combustibles, organics, and sources of heat and ignition Transport separate from flammables Transport securely using secondary containment


Class F : Dangerously ReactiveClass F : Dangerously Reactive

Risks May be unstable or vigorously polymerize May react with water to release a toxic or flammable gas May self-react when shocked or heated Highly reactive with incompatible materials May burn eyes and skin on contact

Examples

Ether

Acrylates

1,3-butadiene

Metal azides


Class F : Dangerously ReactiveClass F : Dangerously Reactive

Handling and Use Follow MSDS recommendations for use and storage Wear protective clothing, especially eye protection Open slowly and carefully & use in fume hood Ensure lab equipment is clean and free of impurities Store away from incompatible chemicals Keep away from heat and ignition sources; avoid sudden temperature changes May require inhibitors to prevent reaction during storage Examine storage containers frequently Store & transport securely

Information ProvidedInformation Provided

Product InformationThis section identifies product name, manufacturer and suppliers names, addresses, and emergency phone numbers, and the intended use of the product.

Hazardous Ingredients This section lists All potentially hazardous ingredients, with the approximate amount (percent), and toxicity data for the individual ingredients. Information regarding the LD50 and LC50 (the amount of a chemical that is expected to kill 50% of a test animal population within a specified time) will also be given. The lower the value the greater the poisoning potential.

MSDSMSDS

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

Hazardous Waste Disposal ProceduresHazardous Waste Disposal Procedures

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 must never 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
