Introduction to Chemistry

2. Lab Safety Locate all safety devices in the room Fire extinguisher
Fire Blanket
First Aid
Eye wash
Broken glass disposal
Lab Coats
Goggles

3. Safe Lab Techniques
When lighting a Bunsen Burner, ensure all long hair and loose clothing is out of the way
When smelling a chemical waft it towards you. DO NOT SMELL it directly
When something is spilled, notify the teacher immediately
If something breaks, notify the teacher immediately; broken glass needs to be disposed of in the designated bin

4. Safe Lab Techniques Never eat or drink in the lab
Wash hands after handling chemicals
When performing a lab, always stay standing, do not sit down.
Never leave a flame or hot plate unattended
Always use appropriate equipment
Always wear safety goggles over your eyes
Never wear open toed shoes in the lab

5. WHMIS
The Workplace Hazardous Materials Information System (WHMIS) is Canada's national hazard communication standard
The key elements of the system are cautionary labelling of containers of WHMIS "controlled products", the provision of material safety data sheets (MSDSs) and worker education programs

6. WHMIS Symbols CLASS A: COMPRESSED GAS
This class includes compressed gases, dissolved gases, and gases liquefied by compression or refrigeration.

7. WHMIS Symbols CLASS B: FLAMMABLE AND COMBUSTIBLE MATERIAL
This class includes solids, liquids, and gases capable of catching fire in the presence of a spark or open flame under normal working conditions.

8. WHMIS Symbols CLASS C: OXIDIZING MATERIAL
These materials increase the risk of fire if they come in contact with flammable or combustible materials.

9. WHMIS Symbols
CLASS D: POISONOUS AND INFECTIOUS MATERIAL Division 1: Materials Causing Immediate and Serious Toxic Effects
These materials can cause death or immediate injury when a person is exposed to small amounts. Examples: sodium cyanide, hydrogen sulphide

10. WHMIS Symbols
CLASS D: POISONOUS AND INFECTIOUS MATERIAL Division 2: Materials Causing Other Toxic EFFECTS
These materials can cause life-threatening and serious long-term health problems as well as less severe but immediate reactions in a person who is repeatedly exposed to small amounts.

11. WHMIS Symbols
CLASS D: POISONOUS AND INFECTIOUS MATERIAL Division 3: Biohazardous Infectious MATERIAL
These materials contain harmful micro- organisms that have been classified into Risk Groups 2, 3, and 4 as determined by the World Health Organization (WHO) or the Medical Research Council of Canada.

12. WHMIS Symbols CLASS E: CORROSIVE MATERIAL
This class includes caustic and acid materials that can destroy the skin or eat through metals. Examples: sodium hydroxide, hydrochloric acid, nitric acid

13. WHMIS Symbols CLASS F: DANGEROUSLY REACTIVE MATERIAL
These products may self-react dangerously (for example, they may explode) upon standing or when exposed to physical shock or to increased pressure or temperature, or they emit toxic gases when exposed to water.

14. Two Types of WHMIS Labels
WHMIS labels include first aid information and details about storage, handling, and disposal. There are two types of WHMIS labels: - Supplier labels - Workplace labels

15. Supplier Labels
Supplier labels are used by the people who make each chemical.
Supplier labels have a strict format.
Hashed marked identifier label
Written in English and French
Supplier Name
Precautionary measures
Risk Phrases
First Aid Treatment
Name of product
Hazard Symbols
Statement referring to MSDS

16. Supplier Labels

17. Workplace Labels
After chemicals are rebottled, a workplace label my replace the Supplier label. Workplace labels are allowed to have different formats.
A Workplace label contains less information than the Supplier label, but it still has enough information to help you use the chemical safely.

18. Workplace Labels Requirements Product name
Information for safe handling of the product
Statement referring to MSDS
WHMIS hazard symbols (optional)

19. Household Chemicals
Each chemical found in your home has a special purpose. The properties of the chemical determine what it will react with. In general we do not want products in our homes to react with each other.
On the other hand there are products that we do want to react with other materials. These are normally cleaners that contain materials such as bleach and ammonia, which are very reactive chemicals

20. Hazardous Household Product Symbols
In order to notify users which chemicals are dangerous and in what ways they are dangerous we use Hazardous Household Product Symbols.
The HHPS has four categories of Hazardous materials as well as three levels of severity.

21. Hazardous Household Product Symbols
The HHPS has four categories of Hazardous Chemicals
The symbols are similar to that of WHMIS with the exception of the Explosive symbol.
 flammable
 toxic
 corrosive
 explosive

22. Hazardous Household Product Symbols
The HHPS has three levels of severity
Caution is the least sever of the three symbols, warning is more severe and danger is the most severe.
