Title: WHMIS Workplace Hazardous Materials Information System


1
WHMISWorkplace Hazardous Materials Information
System
  • City of Langley
  • OHS Training Program

2
What is WHMIS?Workplace Hazardous Materials
Information System
  • Workplace
  • Deals only with products in the workplace
  • Hazardous Materials
  • Dangerous products that may cause fires,
    explosions, or health problems
  • Information System
  • Provides information about hazardous materials

3
Hazardous Materials
  • Hazardous Materials are called
  • Controlled Products
  • Hazardous Materials can result in
  • Irritation of eyes, sensitization of skin or
    lungs, heart ailments, kidney and lung damage or
    cancer.
  • Hazardous Materials can cause
  • Fires, explosions or other accidents when
    improperly stored or handled.

4
3 Basic Elements of WHMIS
  • Labels
  • Labels on controlled products alert workers to
    the identity of the product, hazards, and
    precautionary measures of a controlled product.
  • Material Safety Data Sheets (MSDS)
  • Provides detailed hazard and precautionary
    information and first aid measures of a
    controlled product.
  • Education and Training
  • Workers need to know how WHMIS works, the hazards
    of controlled products in their workplace, and
    the safe work procedures they must follow.

5
Classification
  • Hazardous Materials (controlled products) are
    products that falls into one or more hazard
    classification.
  • There are 8 hazard symbols that describe this
    classification.

6
Class A COMPRESSED GAS
  • Products under pressure
  • Hazard
  • These may explode if exposed to heat or physical
    shock (when dropped).
  • Example
  • Butane, propane, acetylene, and fire
    extinguishers.

7
Class B Flammable/Combustible Materials
  • Substances capable of catching fire or exploding
  • Flammable Gases, Liquids, Solids, Aerosols,
    Combustible liquids, Reactive Flammable Materials
  • Hazard
  • Capable of catching fire in the presence of a
    spark or open flame
  • Example
  • Acetone, isopropyl alcohol, stoddart solvent,
    hydrogen gas, gasoline, kerosene, magnesium
    alloys, propane

8
Class C Oxidizing Material
  • Products causing / contributing to the combustion
    of other materials
  • Hazard
  • These materials increase the risk of fire if they
    come in contact with flammable or combustible
    materials.
  • Example
  • Compressed oxygen, hydrogen peroxide, potassium
    nitrate

9
Class D (3 symbols)Poisonous and Infectious
Material
  • Division 1 Materials Causing Immediate and
    Serious Toxic Effects
  • Hazard Can cause death or immediate injury
  • Example sodium cyanide, hydrogen sulphide
  • Division 2 Materials Causing Other Toxic Effects
  • Hazard Can cause life-threatening and serious
    long-term health effects
  • Example asbestos, isocyanates, xyle
  • Division 3 Biohazardous Infectious Materials
  • Hazard These materials contain harmful
    micro-organisms
  • Example hepatitis B virus, cultures containing
    salmonella bacteria

10
Class ECorrosive Material
  • Caustic and acid materials
  • Hazard
  • These materials can destroy the skin and eat
    through metals.
  • Examples
  • Sodium hygroxide, hydrochloric acid, nitric acid

11
Class FDangerously Reactive Material
  • Products may self-react dangerously
  • Hazard
  • Products may explode when exposed to physical
    shock (dropped) or to increased pressure or
    temperature (heat), or they may emit toxic gases
    when exposed to water.
  • Example
  • Plastic monomers such as butadiene some
    cyanides, benzoyl peroxide, chlorine dioxide.

12
WHMIS Element 1 Labels
13
WHIMS LABELSThere are 2 types of WHIMIS Labels
  • 1. SUPPLIER LABELS
  • Contain the following
  • Product name
  • Hazard symbol
  • Risk phrases
  • Precautionary measures
  • First aid measures
  • Supplier identifier
  • Reference to MSDS (Material Safety Data Sheet)

14
WHIMS LABELSThere are 2 types of WHIMIS Labels
  • 2. WORKPLACE LABLES
  • Apply to (very important)
  • Secondary containers
  • Containers of products received in bulk
  • Employer-produced products
  • Containers with missing or illegible supplier
    labels
  • Contain the following
  • Product name
  • Safe handling procedures
  • Reference to the MSDS (Material Safety Data Sheet)

15
Other means of identification
  • Warning signs
  • Color / number coding systems
  • Symbols
  • For Identifying
  • Piping systems, reaction vessels, tank cars,
    conveyor belts carrying a controlled product

16
WHMIS Element 2 MSDS (Material Safety Data
Sheet)
17
MSDS(Material Safety Data Sheet)
  • A Material Safety Data Sheet is a technical
    bulletin that provides specific hazard
    information, safe handling information, and
    emergency procedures for a controlled product.
  • The MSDSs must not be more than 3 years old.
  • MSDSs should be stored in a binder close to
    where controlled products are kept.
  • If you are unsure about a product or its use ..
    look at the MSDS before handling.

18
The 9 Information Components Included on an MSDS
  • Product Information
  • Ids the product, manufacturer, and supplier and
    it describes the intended product use, and
    manufacturer/supplier contact information in case
    of emergency.
  • Hazardous Ingredients
  • List the specific chemical names, percentages,
    and acute toxicity data.
  • Physical Data
  • General information on physical and chemical
    properties (gravity, boiling point, evaporation
    rate).
  • Fire and Explosion Hazard
  • Lists conditions under which the product may
    catch fire or explode, as well as information for
    developing strategies and procedures to deal with
    fire and explosion hazards.

19
The 9 Information Components Included on an MSDS
  • Reactivity Data
  • Lists conditions and other substances that should
    be avoided to prevent reactions.
  • Toxicology Properties
  • Identifies how the substance enters the body and
    what the short and long term health effects are.
  • Preventive Measures
  • Information on control measures including
    ventilation, personal protective equipment, and
    work procedures.
  • First Aid Measures
  • Specific instructions for immediate treatment in
    case of injury or illness
  • Preparation Information
  • List who prepared the MSDS and when.

WHMIS Element 3 Education Training
22
WHIMIS PROGRAM
  • Assign Responsibilities
  • Manager, Supervisor, employees, OHS committee
  • Establish inventory of controlled products
  • Meet MSDS/label requirements
  • Determine hazards of controlled products
  • Establish workplace controls
  • Establish emergency procedures
  • Provide training for
  • Workers who work with controlled products
  • Workers who work in proximity to controlled
    products
  • Evaluate WHMIS program

23
Education Training
  • WHMIS education must be provided on
  • Major hazards of controlled products in use at
    the workplace.
  • Rights and Responsibilities
  • Employers must train workers in
  • Specific procedures
  • For the safe use, storage, handling disposal of
    a controlled product
  • To follow in case of an escape of a controlled
    product
  • To follow in an emergency involving a controlled
    product
  • Safe use, storage, handling and disposal of a
    controlled product in transit.

24
Questions to Ask Yourself
  • Do you know the hazardous products in your
    workplace?
  • If no, look at your workplace MSDS Binder
  • Do you know where the MSDS is at your workplace?
  • If no, ask your supervisor to show you.
  • Do you know where the Hazard Report Forms are if
    you need to report an unsafe condition,
    equipment, or practice?
  • If no, ask your supervisor to show you.
  • Do you know you have the right to refuse unsafe
    work?
  • Please ensure your take the WHMIS Review Test and
    submit to your supervisor.
