1. Lab Safety

2. General Safety Rules
Listen to or read instructions carefully before attempting to do anything.
Wear safety goggles to protect your eyes from chemicals, heated materials, or things that might be able to shatter.
Notify your teacher if any spills or accidents occur.

3. General Safety Rules
After handling chemicals, always wash your hands with soap and water.
During lab work, keep your hands away from your face.
Tie back long hair.

4. General Safety Rules Roll up loose sleeves.
Know the location of the fire extinguisher, fire blanket, eyewash station, and first aid kit.
Keep your work area uncluttered. Take to the lab station only what is necessary.

5. General Safety Rules
It is suggested that you wear glasses rather than contact lenses.
Never put anything into your mouth during a lab experiment.
Clean up your lab area at the conclusion of the laboratory period.
Never “horse around” or play practical jokes in the laboratory.

6. Glassware Safety
Chipped or cracked glassware should not be used. Show it to the teacher.
Broken glassware should not be disposed of in a classroom trash can. There is a special glass disposal container for it.
When pouring liquids into glassware, make sure the container you are pouring into is resting on a table at least a hands breadth from the edge.

7. Glassware Safety
If a piece of glassware gets broken, do not try to clean it up by yourself. Notify the teacher.
Do not place hot glassware in water. Rapid cooling may make it shatter.

8. Chemical Safety
Wear protective goggles whenever heating or pouring hazardous chemicals.
Never mix chemicals together unless you are told to do so (and then only in the manner specified).
Never taste any chemicals (you should never taste anything in the lab).

9. Chemical Safety
If you need to smell the odor of a chemical, waft the fumes toward your nose with one hand. Do not put your nose over the container and inhale the fumes.

10. Chemical Safety
Follow the instructions of your teacher when disposing of all chemicals.
Wash your hands after handling hazardous chemicals.
Never pour chemicals back into the original container or down the drain. We have a special bucket to dispose of the chemicals.

11. Heating Safety
Use tongs and/or protective gloves to handle hot objects.
Never reach across an open flame or burner.

12. Heating Safety
Always point the top ends of test tubes that are being heated away from people.
When heating a test tube, move it around slowly over the flame to distribute the heat evenly.

13. Heating Safety Only glassware that is thoroughly dry should be heated.
Heat glassware by placing it on a wire gauze platform on a ring stand. Do not hold it in your hand.

14. First Aid Injury: Burns
To Do: Immediately flush with cold water until burning sensation is lessened.

15. First Aid Injury: Cuts, bruises
To Do: Do not touch an open wound without safety gloves. Pressing directly on minor cuts will stop bleeding in a few minutes. Apply cold compress to bruises to reduce swelling.

16. First Aid Injury: The eyes
To Do: Flush eyes immediately with plenty of water for several minutes. If a foreign object is lodged in the eye, do not allow the eye to be rubbed.

17. WHMIS
WHMIS stands for Workplace Hazardous Materials Information System
The purpose of WHMIS is to reduce injury, illness or disease caused by exposure to hazardous materials.

18. New to WHMIS
Globally Harmonized System of Classification and Labelling of Chemicals (GHS) has been adopted
Products previously called “controlled” are now called “hazardous”
Material Safety Data Sheets (MSDS) are now called Safety Data Sheets (SDS); with no expiry dates

19. New to WHMIS Pictograms on labels and Safety Data Sheets have changed
Signal words such as “Danger” have been added to Supplier Labels
More information have been added to Supplier Labels and Safety Data Sheets

20. Chemicals in your daily life have characteristics that make them useful, hazardous, or both.
Some types of matter that you use everyday can be hazardous
Information labels give you information about how to properly handle matter

21. Chemical Safety Around the House
Hazardous Household Products Symbols (HHPS)
Each symbol has two types of warnings:
Whether the hazard is the container or contents
The type of hazard

22. HHPS: The Borders Dangerous Container
Border looks like a traffic yield sign
Container is dangerous

23. HHPS: The Borders Dangerous Product
Border looks like a traffic stop sign
Contents of the container are dangerous

24. HHPS: The Hazards Explosive Container can explode
If punctured or heater, pieces can cause serious injuries

25. HHPS: The Hazards Corrosive
Product inside the container will burn the throat or stomach if swallowed
Burn skin or eyes or contact

26. HHPS: The Hazards Flammable
Product will catch on fire easily if near sparks, flames, or heat

27. HHPS: The Hazards Poisonous
Product will cause illness or death if you eat or drink it
Smelling or licking the product may be enough to cause harm

28. HHPS: Household Hazardous Product Symbols
Figure 2.2 Household hazardous product symbols (HHPS). Name two products with HHPS on their containers.

29. Discussion Questions What is the HHPS system? Why is it used?
Which HHPS would be on spray paint?

30. SDS Sheets Identification Hazard(s) identification
Composition/information on ingredients
First-aid measures
Fire-fighting measures
Accidental release measures

31. SDS Sheets Handling and Storage Exposure controls/personal protection
Physical and chemical properties
Stability and reactivity
Toxicological information
