Objectives

• Recognize and understand the two types of WHMIS labels

• Understand Material Safety Data Sheets• Identify 6 Classes of Controlled Products• Understand the Main Hazards associated

with each class

What does WHMIS mean? W – Workplace

H – Hazardous

M – Materials

I – Information

S – System• WHMIS is a national hazard communication system. It is

Canada wide legislation developed through collective efforts by Industry, Federal & Provincial Governments.

• WHMIS was implemented on October 31, 1988 through coordinated Federal, Provincial and Territorial Legislation.

Why was WHMIS created?• It was created in response to Canadian workers’ “Right to

Know” about the safety and health hazards that may be associated with the materials or chemicals they use at work.

• It was created to reduce the injuries and illness caused by hazardous materials that can cause or contribute to many serious health effects such as:

• Irritation of the skin (rashes)• Burns• Sensitization• Heart, liver, kidney and pulmonary ailments• Cancer• Reproductive toxicity• Can cause fires or explosions.

What is WHMIS?

• WHMIS has 3 main elements:

1.Product labels – on containers of hazardous materials

2.Material Safety Data Sheets (MSDS) – providing further detailed information

3.Worker Education – on how to use this information

WHMIS – A Shared Responsibility

Supplier

Employer

Employee

Supplier Responsibility

The Supplier is responsible for: • Determining what are ‘controlled products’• Assessing applicable health and safety info• Classify products• Label products with a WHMIS label• Prepare and provide customers with MSDS's• Update MSDS's at least every three years

Employer ResponsibilityManitoba’s Workplace Safety and Health Act requires

employers to take all reasonable measures to protect the health and safety of all workers. The employer responsibilities ensure that:

• All controlled products are labeled with appropriate supplier or workplace labels.

• MSDS are current and no more than three years old.

• MSDS are provided for all controlled products, and they are located in a place readily accessible to everyone who works there

• Workers receive appropriate proper WHMIS training.

Employee ResponsibilityThe Manitoba Workplace Safety and Health Act

requires workers to cooperate with their employers to protect their own and other workers’ health and safety.

We do this by:• Participating in education and training sessions that is

provided.• Taking necessary steps to protect ourselves and our

co-workers- ex. Follow Safe work instructions and wear PPE if required.

• Participating in identifying and eliminating risks

Exclusions from WHMISThere are some exclusions under WHMIS because they are regulated by other acts or regulations (TDG or FDA). Example- wood and wood products, Consumer products, Cosmetic Food and Drug, Pest Control Products.•Hazardous Materials being transported under the Transportation of Dangerous Goods Act

ClassificationsDoes a product meet WHMIS criteria?

The Hazardous Product Act (HPA) deals with 3 types of hazardous products:

• Prohibited – May not be advertised, sold or imported (e.g. drywall cement containing asbestos)

• Restricted – Must meet Consumer Chemicals and Containers regulations. (e.g. Bleach)

• Controlled – Products regulated by WHMIS legislation (6 classes).

What are Controlled Products?• Products, materials or substances

that meet the criteria for one or more of the six WHMIS product classes.• some of the classes have divisions and

subdivisions• Each class has a specific symbol to help

people identify the hazard quickly

LABELSObjectives – you should be able to

recognize the following:• Two types of labels: supplier and

workplace• Distinctive border used around supplier

label• 8 possible hazard symbols• 7 components of a supplier label • 3 components of a workplace label

Labels

There are two types of WHMIS labels:

• Supplier Labels

-- These are labels that suppliers are required to display on their products.

• Workplace Labels

-- These are used by employers when supplier labels are not available.

Supplier Labels

Supplier labels must appear on controlled products in their original (supplier) containers. These products include:

• Controlled products sold by Canadian suppliers and distributors to Canadian work sites.

• Controlled products imported into Canada for use at Canadian work sites.

• You may refuse to accept a product that arrives at your work site without the proper label or MSDS.

Supplier Labels

Supplier Labels must contain the following information:

1. Product Identifier (name of the product)2. Supplier Identifier (name and address)3. Reference to MSDS (statement that it is available) 4. Hazard Symbols (one or more of the 8 symbols)5. Risk Phrases (description of the hazard and the effects of

exposure)6. Precautionary Measures (instructions for safe handling and use)7. First Aid Measures (how to treat exposures)

Enclosed in the distinctive WHMIS cross-hatched border Must be bilingual (English and French)

FIRST AID:EYES: Flush with water for 15 minutes. Consult physician.

SKIN: Flush with water for 15 minutes. Consult physician.

INGESTION: Do not induce vomiting. Give large quantities of water. Consult with physician.

Small Container Labels

• For Controlled products packaged in containers less than 100ml, only the following is required:

• Product Identifier • Supplier Identifier • Hazard symbols• Reference to MSDS

Workplace Labels are Required:

• On controlled products produced and used in the workplace

• If the label becomes illegible

• If received from a supplier and

transferred to another container*

*Not required if transferred material is used in its entirety prior to the end of the work shift and remains under the control of the worker.

Workplace Labels

Three pieces of information are required on all workplace labels:

1. Product Identifier

2. Precautionary Measures

3. A reference to MSDS

Workplace Label

PRODUCT IDENTIFIERMethanol

Precautions:Use in well ventilated

area

Avoid contact with skin and eyes

Keep away from spark and flame

Refer to Material Safety Data Sheet

FRANCAIS AU VERSO

Workplace Label

Workplace Labels• In a few special cases, any form of clear

identification, such as the name of the product, a color code or a numbering system may be used instead of a work site label. These cases include controlled products:

• in pipes, reaction vessels, ore cars• on conveyor belts• in or on other in-plant conveyance systems• transferred into work site containers for use by

one worker only and used up during the shift on which the container was filled.

RULES FOR LABELING

Part 2 – Material Safety Data Sheets

• Sent by Suppliers (Legal Obligation)

• Must be accessible to ALL workers in the workplace

• Must be kept up to date (replaced at least every 3 years, old copies MUST be kept 30 years)

• Must be made available to doctor in the event of exposure

• English & French version (bilingual)

Material Safety Data Sheets

MSDS Sheets contain NINE different kinds of information

1. Product Identification & Use 6. Toxicological Properties2. Hazardous Ingredients 7. Preventative Measures3. Physical Data 8. First Aid Measures4. Fire or Explosion Hazard 9. Preparation Information5. Reactivity Data

* Under some circumstances suppliers and employers may withhold vital product ingredients, which is called a “Trade Secret”.

* This information MUST be given to a medical professional in medical emergency.

MSDS 1. Product Identification and Use

• Product Identifier• Product Use• Manufacturer’s name• Manufacturer’s address• Supplier’s name

MSDS 2. Composition/information about

ingredients

• The most hazardous controlled ingredients are listed if they make up more than 0.1% of the product.

• Other less hazardous, controlled product ingredients are listed if they make up more than 1% of the product.

• Lists LD 50, LC 50 and TLV.

LD50 - Lethal Dose 50%

• LD50 is the amount of a substance that, when administered by a specific route of entry (e.g. oral or skin absorption) over a specified period of time, is expected to cause the death of 50 per cent of a defined test animal population.

• Expressed as mg/kg.

• The smaller this number is, the more toxic the substance is.

LC50 - Lethal Concentration 50%

• LC50 is the concentration of a substance in air that, when administered by inhalation over a specified period of time, is expected to cause the death in 50 per cent of a defined test animal population.

• Expressed as ppm or mg/m3

• The smaller this number is, the more toxic the substance is.

Threshold Limit Value (TLV)

• TLV (TWA) is an 8-hour time-weighted average believed to be the average concentration to which most workers can be exposed during an 8-hour workday, day after day, without harmful effects.

• TLV (STEL) is a 15 minute short term exposure limit

• Ceiling (C) is a maximum concentration never to be exceeded

MSDS 3. Physical Data

The MSDS provides a range of technical data which allows people to assess how the chemical behaves under differing situations and plan safe work procedures.

• Physical State: gas, solid, liquid….• Odor & Appearance: noticeable smell??• Vapor Pressure: measure of how readily vapors are formed.

Materials with high vapor pressures can be hazardous, particularly in enclosed areas

• Vapor Density: weight per unit volume of a pure gas or vapour.• Evaporation Rate: how quickly the material becomes a vapour at

room temperature (i.e. how fast does it become airborne)

MSDS 3. Physical Data

• Boiling point: the temperature which the material changes form a liquid to a gas

• Freezing point: solid becomes a liquid• Specific Gravity: is the product heavier or lighter

than air ?? (<1 heavier; >1 lighter)• Coefficient of Water/Oil Distribution: if >1 then the

product mixes better with water and is more likely to be absorbed by eye or lung tissue; if <1 the product is more oil soluble and more likely to be absorbed by the skin

MSDS4. Fire & Explosion Data

The MSDS provides information on which the workplace can plan fire prevention and which emergency responders may need in the event that a fire occurs

• Flammability: Indication of whether the product is flammable and the conditions under which a fire might occur

• Means of extinction: types of suitable extinguishers• Flashpoint: lowest temperature at which a liquid or solid gives

off enough vapour to form a flammable air-vapour mixture near its surface. (Flammable < 37.8oC, combustible > 37.8oC)

• Upper Flammable Limit (UFL): the highest concentration of gas or vapour which will burn or explode if ignited.

MSDS4. Fire & Explosion Data

• Lower Explosive Limit (LEL): the lowest concentration of gas or vapour which will burn or explode if ignited.

• Auto-Ignition Temperature: the lowest temperature at which a material begins to burn in air in the absence of a spark or flame.

• Hazardous Combustion Products: hazardous products formed when burned

• Explosion Data: will the material burn or explode upon impact? Is the material sensitive to friction or static discharge?

MSDS5. Reactivity Data

WHMIS requires that the supplier provides information about possible hazardous chemical reactions that may occur

• Many laboratory chemicals are highly reactive • Chemical Stability: is the product stable or unstable if

chemical is exposed to: --other chemicals -- water --temperature changes --shock, vibrations, pressure

• Even some of the trades or custodial chemicals can react with other chemicals or can react if exposed to heat or mixed with catalysts or activators

MSDS6. Toxicological Properties

WHMIS requires the supplier to describe how people might come into contact with the product and what the short and long term effects would be if someone was over-exposed

• Route of entry into the body• Effects of acute (short term) exposure• Effects of chronic (long term) exposure • Legal exposure limit


• How will the product enter the body?Four Routes of Entry:– Skin contact/skin absorption (e.g. burn from acid)– Eye contact– Inhalation– Ingestion

• How will the product affect your health? – Exposure limits, irritancy, sensitization – Carcinogenicity, teratogenicity, reproductive

toxicity, mutagenicity, synergistic products


• Carcinogenicity – cancer causing• Teratogenicity – abnormal reproduction• Embryotoxicity – embryo poisoning• Reproductive toxicity – sterility• Mutagenicity – causes genetic changes• Synergistic materials – materials that should

not be combined because the combination produces a toxic effect that may not be present when the materials are kept separate

MSDS7. Preventative Measures

Supplier lists precautions for safe handling of the product which should be taken in storing, handling, using and disposing of the product

This is one of the most useful sections of the MSDS

You should review the information in this section with your supervisor and assess how appropriate the supplier's suggestions are in your particular work situation


• Engineering Controls: equipment needed to prevent over-exposure– ventilation, equipment design.

• Personal Protective Equipment (PPE): gloves, respiratory protection, eye protection, foot wear, impervious clothing.

• Spill Procedures: PPE for Emergency workers, control measures (suitable absorbing materials)


• Waste Disposal: waste container design; safe handling procedures; regulatory requirements

• Storage requirements: temperatures, control source of ignition, limits on shelf life, special instructions.

• Shipping Information: special containers, restrictions on what other substances can be carried with the material.

MSDS8. First Aid Measures

The MSDS provides first aid information similar to what is presented on the product label

• Information on the safe evacuation and immediate treatment of a person suffering from overexposure to a controlled product.

• All workers should know where First Aid stations are and how to use emergency equipment.

• Medical personnel will need a copy of the MSDS, or at least label information, to effectively treat the victim

MSDS9. Preparation Information

WHMIS regulations require the supplier to indicate:

•Name of the person or Company that produced the MSDS.•Contact information for the producer of the MSDS.•Preparation date of the MSDS, this must be no more than 3 years old and must be updated when new information about the controlled product becomes available.

Material Safety Data Sheets - Summary

• An MSDS is sent to a company with every new controlled product it buys.

• MSDS must never be more than 3 years old (replaced MSDS sheets must be retained for 30 years – please forward to Safety Office).

• MSDS sheets for controlled products at a work site must be kept in a place where workers have easy access to them.

• Read them BEFORE using the product

Part 3 – WHMIS Worker Education Programs

Do all workers require WHMIS education?

• All work-site personnel who work with or close to controlled products, or who do work involved in the manufacture of a controlled product, must be provided with WHMIS worker education.

Worker Education Programs

WHMIS worker education includes generic and work-site specific programs.

Generic worker education programs include:• General introduction to WHMIS• Training in the required content of WHMIS labels and

MSDS• Training in the purpose and significance of that

information to workers’ health and safety on the job.

Worker Education Programs

Work-site specific education programs include:• Hazard information• Product identification used at the workplace• Procedures for safe use, storage and handling

of controlled products• Procedures for dealing with emissions and

emergencies at the workplace.
