WHMIS Education & Training
1
Introduction to WHMIS WHMIS provides information about hazardous materials used in the workplace WHMIS calls these hazardous materials controlled products under WHMIS, workers have the right to receive information about hazardous materials or controlled products they use in the workplace --- its identity, hazards and safety precautions 2
What is a hazardous Substance?
Any substance that can cause illness, disease or death to unprotected people For example: gasoline bleach chlorine 3
WHMIS is the Law WHMIS is based on a law in Canada that came into effect in 1988 Canada wide (Federal and provincial) meaning that WHMIS rules apply in every province and territory of Canada 4
WHMIS What does it stand for?
W – workplace
H – hazardous
M – materials
I – information
S - system

Why is WHMIS needed?
In our daily lives there are hundreds of materials and chemicals that have been developed to make our work easier and to allow us to make better products In this process there are substances that are used that can be dangerous to people if handled the wrong way WHMIS lets us know which materials are dangerous and how we can protect ourselves when we handle them 6
How does WHMIS Work?
Companies that supply hazardous materials provide labels on the products and detailed information sheets called Material Safety Data Sheets Employers ensure products are labeled and provide training and education to employees These steps lead to informed workers 7
Summary of WHMIS Requirements
1) Training 3) Material Safety Data Sheets (MSDS) 2) Labels on Products

Forms Hazards Take & HCA Examples
Gases: Liquids:
•Cleaning Agents •Gasoline (for HCA vehicles)
Solids:
•Road salt & sand •Toner •Fiberglass •Granular chlorine (Lakeland pool) •Oxygen &Acetylene for welding in the workshop •Chlorine (Wild Water Works ) •Natural Gas 9
Dangerous Materials Enter the Body Through: Ingestion (mouth) Inhalation (nose) Absorption & Injection (skin) 10
Ingestion Lack of good hygiene such as hand washing can lead to an employee eating dangerous materials Material is on hand, touch food and then eat it Or, leave food out in an area where it can become contaminated 11
Inhalation When you breathe, air goes to your lungs and then into your blood Inhalation is the most common way workers get exposed to chemicals in the workplace 12
Absorption & Injection Your skin and eyes are able to absorb materials that get on them Be sure to wear protective equipment as required such as gloves, goggles, aprons etc. to protect hands and body or avoid contact Practice good hygiene 13
Absorption & Injection Biohazards can enter the body through needle stick injuries This can happen to litter collectors if needles have not been disposed of properly First aiders can also be at risk 14
What effect can chemicals have in the body?
• • • • • • Headaches / nausea Rashes Burns Irritation Cancer Many other effects 15
Acute & Chronic Effects
ACUTE:
If a dangerous material makes you sick immediately from coming into contact with it, it has an acute effect e.g. vapour makes your eyes water
CHRONIC:
If a dangerous material makes you sick little by little, or maybe years later, it has a chronic effect e.g. cancer from smoking cigarettes 16
Labels One way WHMIS helps protect you is through labels Labels tell you what is inside a container and alerts you to the hazards of the product All dangerous or hazardous materials (in containers, bottles, boxes, cans or drums) must have labels A pipe even has to have a label on it if there is a dangerous material in it 2 types of labels: supplier and workplace 17
Supplier Label Information Every hazardous material that gets shipped to us is supposed to have a supplier label Tells you what the hazardous material is, risk phrases, first aid details Name and address of company that made it Refers you to MSDS for more information Written in English & French 18
Supplier Label 19
Workplace Label Often, hazardous materials get put into smaller bottles or spray cans so they can be handled easily When we put it in a smaller container, this new container has to be labeled as well Can use our own workplace label or write directly on the container using permanent marker Must state the product name, safe handling information and reference to MSDS 20
Sample Workplace Label ACETONE Flammable Keep away from heat, sparks and flames Wear rubber gloves and safety goggles Material Safety Data Sheet Available 21
WHMIS Hazard Symbols WHMIS has 8 symbols to assist you in identifying the hazards associated with a hazardous material Not all products are controlled by the WHMIS legislation so they may not have the exact same symbols as WHMIS You’ll see these other symbols on products you commonly find around the house and garden, including cosmetics (like hairspray), pesticides and some household products (like oven and glass cleaners) 22
WHMIS Symbols (8 in total)
Materials causing immediate & serious Toxic Effects Materials causing other Toxic Effects
23
WHMIS Symbols
Flammable & Combustible Material Compressed Gas
24
WHMIS Symbols
Corrosive Material Dangerously Reactive Material
25
WHMIS Symbols
Oxidizing Material Biohazardous Infectious Materials
26
Compressed Gas 27
Compressed Gas Safety The danger with compressed gases is that they can explode because the gas is being held in a cylinder under pressure It may cause its container to explode if heated in a fire or dropped Products at HCA: fire extinguishers, spray cans of disinfectant, spray adhesive 28
Compressed Gas Safe Handling Keep containers upright and secure Keep closed when not in use Keep away from potential sources of heat 29
Flammable & Combustible Material 30
Flammable & Combustible Flammable or combustible means that the material can burn or catch fire easily Slight difference between the two words Flammables burn more easily, will start burning at lower temperatures than combustibles Both may cause a fire when exposed to heat, sparks or flames or as a result of friction Products at HCA: gasoline, liquid paper 31
Safe Handling of Flammables & Combustibles Do not smoke when working with or near the material Keep away from heat sources Do not expose material to welding or open flames Keep in a cool, fire-proof area 32
Oxidizing Materials 33
Oxidizing Materials Oxidizers can break down under certain conditions and give off oxygen Oxidizing materials make another material burn May cause a fire if in contact with combustible materials such as wood Pose a fire and / or explosion risk in the presence of flammable or combustible material Can burn skin and eyes upon contact Products at HCA: chlorine, oxygen (used with acetylene for welding and also for first aid at Wild Waterworks) 34
Safe Handling of Oxidizing Materials Do not store near combustible material Keep away from heat Keep the container closed Store in a cool place Do not smoke when working near the material Make sure you wear proper protective equipment 35
Materials Causing Immediate & Serious Toxic Effects 36
Immediate & Serious Toxic Effects These materials can have an acute effect (make you sick quickly) and can kill you May cause permanent damage if it is inhaled or swallowed or if it enters the body through skin contact May burn eyes or skin upon contact Products at HCA: chlorine, anti-freeze, some cleaning supplies 37
Safe Handling of Immediate & Serious Toxic Materials Handle these materials with caution Do not get in your mouth (wear gloves and wash hands) Do not breathe in, use in well ventilated area or wear a mask / respirator Do not get in eyes, wear protective eye wear Substitute with something less toxic if possible 38
Materials Causing Other Toxic Effects 39
Other Toxic Effects These are toxic materials that have chronic effects can make you sick later Can give you red, itchy skin, a cough or sore eyes May cause permanent damage as a result of repeated exposures over time Products at HCA: paint, acetone, cleaning supplies, fibreglass, brake fluid; just about every material will have this label 40
Safe Handling of Other Toxic Effects Do not get in your mouth (wear gloves and wash hands) Do not breathe in, use in well ventilated area or wear a mask / respirator Do not get in eyes, wear protective eye wear Substitute with something less toxic if possible 41
Biohazardous & Infectious 42
Biohazardous & Infectious This symbol means that the material can cause serious disease resulting in illness or death You see this symbol where people work with materials that come from people or animals, like blood, tissue or body fluids Catch diseases from viruses, bacteria and parasites Biohazardous materials are found in hospitals, labs, sewage treatment plants and the meat industry 43
Biohazardous & Infectious At HCA, first aiders have to be careful about coming into contact with blood All kitchen and food concessions in the parks areas have to practice safe food handling procedures to avoid contaminating food maintenance workers need to be alert for improperly disposed of needles that could be found in garbage containers or on the ground 44
Corrosive Material 45
Corrosive Materials Corrosive materials can burn skin and eat through metal Can cause severe eye and skin irritation upon contact, depending on how strong the corrosive material is May be harmful if inhaled Products at HCA: toilet bowl cleaner, cement, bleach, degreaser, chlorine 46
Safe Handling of Corrosives Ensure material cannot splash on you, wear gloves, safety glasses and apron if required Be careful what kind of container you pour corrosive materials into, strong corrosives may eat through metal containers, causing a leak and spill Use in well ventilated areas 47
Dangerously Reactive Material 48
Dangerously Reactive Materials This material can explode or make a poisonous gas It is very unstable May react with water to release a toxic or flammable gas May explode as a result of shock, friction, or increase in temperature May explode if heated when in a closed container None at HCA, but example would be dynamite 49
