Lab Safety

Lab Safety•Safety MUST be our top priority!

•Need to know the rules BEFORE the lab and use them IN the lab!

• If not something like this could happen to one of you.

Lab Safety•Activity 1-1A (Page 9)•Create a sub heading and record your ideas in your note book

Appendix A: Lab Safety Rules

WHMIS

• WHMIS is useful because you can very quickly see what type of hazard a chemical substance presents.

WHMIS

MSDS

MSDS stands for material safety data sheet

• An MSDS gives us much more information! This helps people working with chemicals to remain safe on the job.

MSDS

MSDS stands for material safety data sheet

• An MSDS gives us much more information! This helps people working with chemicals to remain safe on the job.

MSDS• Each chemical substance has an MSDS. This tells you important things like:

• Possible health effects of the chemical

• What to wear when handling it

• First aid procedures in case of emergency

• How to store and dispose of it properly

• What to do if it catches fire

WHMIS vs MSDS• WHMIS only tells us HOW a controlled product is harmful.

• MSDS tells you specific information about the controlled product.
