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 PartsWHMIS has 3 Main Parts

Labels – provide information about the hazards of the product

Material Safety Data Sheets (MSDS) – provide further detailed information about the hazards associated with the product

Education – how to use the information provided in the MSDS and on the Label

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…

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

WHMIS Does Not ApplyWHMIS Does Not Apply

WHMIS does not apply to products covered by:

Explosives Act Food and Drugs Act Pest Control Products Act

19

Division 1 – Materials Causing Immediate and Serious Toxic Effects (acute)

Division 2 – Materials Causing Other Toxic Effects (chronic, delayed)

Division 3 – Biohazardous Infectious Material


Class D : Poisonous and InfectiousClass D : Poisonous and Infectious


Class D : Poisonous and InfectiousClass D : Poisonous and Infectious Division 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 eyes

Many 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



RisksInfectious 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 UseWear protective clothing to avoid all exposures: skin, inhalation, ingestion, and injectionWork in a fume hood or BSCAvoid creating dust, vapours, and aerosolsObtain appropriate immunizationsHandle exterior containers as though it is contaminatedStore and transport securely to prevent accidental spillage


Class E : Corrosive MaterialClass E : Corrosive Material

RisksWill burn human tissue including skin, eyes, nose mouth, throat & lungsWill corrode many lab related materials particularly metalsFumes may damage the environment

Examples Strong acids & bases Hydrogen fluoride Hydrogen chloride


Class E : Corrosive MaterialClass E : Corrosive Material

Handling and UseWear appropriate protective clothingWhen possible work in the fume hoodOpen containers slowlyWhen 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 ignitionTransport separate from flammablesTransport securely using secondary containment


Class F : Dangerously ReactiveClass F : Dangerously Reactive

RisksMay be unstable or vigorously polymerizeMay react with water to release a toxic or flammable gasMay self-react when shocked or heatedHighly 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

Provide detailed information on the hazards of a controlled product An important element for developing safe work procedures and

control measures Must be provided by the supplier, or If you have created a product,

you must prepare a MSDS Risk Group 2 and higher biological agents also require a MSDS or a

Pathogen Safety Data Sheet (PSDS)

Material Safety Data Sheets (MSDS)Material Safety Data Sheets (MSDS)

MSDS’s must be replaced every 3 yearsAll MSDS must be kept for a minimum of 30 years

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

MSDSMSDS


Reactivity DataProvides information regarding stability, self-reactivity, hazardous decomposition products, and conditions to avoid when using the product.

Toxicological PropertiesIdentifies how the substance can enter the body and the possible health effects from short term (acute) exposures such as irritation, sensitization; and long-term (chronic) such as liver or kidney damage, sensitization, cancer, or reproductive effects. Known exposure limits will also be given.

MSDSMSDS


Preventative MeasuresProvides preventive measures you can take to protect yourself from exposure including: extra ventilation, personal protective equipment (PPE), safe use, handling, storage, disposal, transport, and spill control.

Preparation informationIndicated who was responsible for preparation and date of preparation of MSDS. It is 3 years from this date when the MSDS needs to be renewed.

Every year the School Division coordinates a hazardous waste pick up with Miller Environmental.

Hazardous waste pick up occurs every June. Hazardous waste labels and Miller Environmental Hazardous

Waste Inventory sheets are available on the PTSD website. Science teachers should incorporate waste disposal into lab

procedures or experiments Reminder: NO disposal of Hazardous Waste is permitted

down the drain (unless it has been neutralized and pH verified) or regular trash can.

Remember that your end point is someone’s starting pointRefer to the PTSD Workplace S&H 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

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 S&H Officer is also available to assist with the cleanup of spills beyond

the capabilities of available staff

Information on spills cleanup can be found on the PTSD Workplace S&H website

Picric Acid and Nitro Compounds Dry 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 requirements

Peroxide Forming Compounds Example ethers, dioxanes, sodium amide Peroxide formation may be initiated by light or air Peroxides are prone to explosive decomposition when subjected to

heat, shock, or friction (opening the lid)

As part of the Manitoba Workplace Safety and Health Act and Regulations, an inventory of chemicals is required at the Division every year.

The Division provides WellNet as a general database for all chemicals used in the Division. It can be accessed from the PTSD Workplace Safety & Health website.
