Transcript of WHMIS
Material Safety Data Sheets
Employers should create a WHMIS inventory for all hazardous products because it is mandatory that an MSDS is available for each product. MSDS must be updated every three years.
Participating in this presentation is part of your education. It is important to learn how the products you use can affect your body.
WHMIS is a Canada-wide system which was created by business, labour and government so that people who handle, use or store hazardous materials on the job have the information to protect their health and safety. Provincially, the Ministry of Labour enforces WHMIS along with the Occupational Health & Safety Act.
WHMIS is made up of three parts:
1. WHMIS labels
2. Material Safety Data Sheets
3. Worker Education
These are placed on containers by the supplier or manufacturer of the hazardous material.
They must contain the following information:
>referral to Material Safety Data Sheet (MSDS)
>first aid measures
Supplier labels must be presented in both English and French and have the distinctive WHMIS border.
The employer is responsible for ensuring that all hazardous material containers have labels. Should you encounter a substance that does not have a label (or you are unsure of the contents) bring it to the attention of your supervisor.
Workplace labels are used:
> when hazardous materials are produced in the workplace
> when hazardous materials are poured from the original container into another container in the workplace
> if the supplier label is missing or illegible
Workplace labels must have the following pieces of information:
*Safe handling instructions
CLASS D - Poisonous and Infectious Material
Materials causing immediate and serious toxic effects
Materials causing other toxic effects
Biohazardous Infectious Material
Dangerously Reactive Material
MSDS must contain the following information...
Breathing toxic substances through the nose and mouth into the lungs is one of the most common routes of entry into the body. Gases, vapours, dusts, fumes and smoke may cause damage to the respiratory system itself, or they can pass through the lungs into other parts of the body.
Ingesting is another way for toxic substances to enter the body. Toxic materials may reach the stomach when food or drink is consumed or when cigarettes are used in an area where hazardous materials are present. They can also be ingested when workers do not wash their hands before eating or smoking. Once swallowed, the toxic substances enter the bloodstream and travel to the liver and kidneys.
Absorption through the skin is another common way for toxic substances to enter the body. Some chemicals can enter through the skin, reach the bloodstream and damage other parts of the body. This includes injection of hazardous materials by way of skin cuts, skin punctures or by needle sticks.
Under WHMIS, employers are responsible for ensuring
>that the Joint Health & Safety Committee is consulted regarding Worker Education
>that labels are properly affixed to all hazardous products and
>there is an MSDS available.
Thank you for participating in this training module. If you have any questions please do not hesitate to ask.
ROUTES OF ENTRY
It's important to know how to handle the products you work with safely. Educating yourself about these products is the safest way to accomplish that. Use the information that is provided for you. Always ask questions if you don't understand what you are working with.
1. Hazardous ingredients
2. Preparation information
3. Product Information
4. Physical Data
5. Fire or explosion hazard
6. Reactivity data
7. Toxicological properties
8. Preventive measures
9. First aid measures
Let's look at the M.S.D.S for lead and identify these requirements.
