Annual WHMIS Review Training


August 2009 2

INTRODUCTION

WHMIS stands for

Workplace Hazardous Materials Information System


August 2009 3

The Main Components of WHMIS

• Labels (Supplier and Workplace)

• Material Safety Data Sheets

• Worker Education and Training (Generic and Annual Review)


August 2009 4

RESPONSIBILITIES

Manufacturer/Supplier• Classification

• Label all controlled products as a condition of sale

• Provide a MSDS as a condition of sale

• Review and update MSDS every three years

Employer• Ensure that controlled

products are labeled

• Obtain an up to date MSDS for all controlled products used in the workplace

• Provide worker education and training


August 2009 5

RESPONSIBILITIES

Workers• The right to know about hazardous materials you may be

exposed to on the job including the right to review labels and MSDS and to receive training

• The right to be consulted in the content and delivery of the training

• Responsible to report missing or illegible labels, missing or out of date MSDS, and

• Responsible to work in a safe manner and follow all work procedures required by the employer

CLASSIFICATION

WHMIS requires the manufacturer to classify their hazardous materials into one or more of the following (6) Hazard Classes and (8) symbols.


August 2009 7

CLASS A: COMPRESSED GAS

A compressed gas is a material that is normally held under pressure in a container at room temperature.

Hazards:• Explosion, Projectile• Frost BitePrecautions:• Store securely, upright and

away from sources of heat• Do not puncture• Protect valves


August 2009 8

CLASS B: FLAMMABLE & COMBUSTIBLE

Class B is sub-divided into 6 divisions:

1. Flammable Gases

2. Flammable Liquids

3. Combustible Liquids

4. Flammable Solids

5. Flammable Aerosols

6. Reactive Flammable Materials


August 2009 9

CLASS B: FLAMMABLE & COMBUSTIBLEHazards:• Fire, explosion• Hazardous decomposition

products (smoke)• Flash-backPrecautions• Use in well ventilated area• Avoid sources of ignition• Store properly away from

incompatible materials and sources of heat


August 2009 10

CLASS B: FLAMMABLE & COMBUSTIBLE

Note: Only Board-approved candles should be used on religion tables. Tapers may be used during school masses. Non-approved candles can be used for display purposes only – but never lit. Smoking is not permitted on Board property.


August 2009 11

CLASS C: OXIDIZING MATERIALS

Oxidizing materials cause/contribute to the combustion of other materials. Hazards:• Fire• Fire burns more

vigorouslyPrecautions:• Keep away from

incompatible materials and flammable or combustible materials


August 2009 12

CLASS D: POISONOUS & INFECTIOUS

Class D comprises three divisions, each with its own symbol.


August 2009 13


Division D1: Toxic Immediate and Severe

Example:

Carbon Monoxide


August 2009 14


Division D3: Biohazardous and Infectious

Examples: blood-contaminated materials (Hepatitis A, B, C, HIV).

Other biohazards: West Nile (mosquitoes) Lime Disease (tics) Hanta Virus (mouse droppings)


August 2009 15


Division D2: Other Toxic Effects

Examples:

Latex Paint

Solvents (e.g varsol)

Asbestos


August 2009 16


Hazards:• Chemical burns to skin and eyes• Respiratory irritation, poisoning • Acute and/or chronic health

impairmentPrecautions:• Use appropriate ppe• Avoid contact • Follow all safety precautions


August 2009 17

CLASS E: CORROSIVE

Corrosives are materials that can attack and destroy on contact human tissues, clothes, and other materials, even metals.

Hazards:• Burns to skin and eyes• Respiratory irritation or

damagePrecautions:• Use appropriate ppe• Avoid splashing • Avoid mist generation


August 2009 18

CLASS F: DANGEROUSLY REACTIVE

These materials can undergo vigorous reactions when heated, pressurized or agitated. They may also react with water to evolve a poisonous gas.

Hazards:• Thermal burns Respiratory

irritation or damage

Precautions:• Use appropriate ppe• Avoid incompatible materials

or conditions


August 2009 19

LABELS – SUPPLIER LABELS

1. Product Identifier2. Supplier Identifier3. Statement referring to the

Should you require a workplace label, or have any

difficulty interpreting information on a label, contact your supervisor.


August 2009 20

LABELS - WORKPLACE

1. Product Identifier

2. Safe handling instructions

3. Statement referring to the MSDS

Should you notice that an MSDS is missing or is outdated report this to you supervisor immediately.


August 2009 22


1. Product Identification • product identifier

• supplier/manufacturer contact information

• intended use of product

2. Hazardous Ingredients• Concentration of hazardous

ingredients and their toxicological properties

3. Health Hazard Information• Effects of exposure

• Symptoms of over exposure

4. First Aid Measures


August 2009 23


5. Physical Data• Colour, odour, specific gravity,

density, vapour pressure etc.

6. Fire/Explosion Data• UFL, LFL, means of extinction

7. Reactivity Data• Conditions, hazardous

decomposition products.

8. Safe Handling Measures• Storage, use, disposal requirements• ppe

9. Preparation Data• Date of preparation


August 2009 24

ROUTES OF ENTRY

Exposure occurs when the toxic substance either comes in CONTACT with and/or ENTERS the body.

Exposure occurs through the following 4 ROUTES OF ENTRY.

Inhalation, Absorption (Skin or eyes), Ingestion, Injection


August 2009 25
