But that’s not all…

23. What happens if you don’t follow safety procedures?
You will be removed from lab and given a very boring writing assignment to replace it.
It is possible to be permanently removed from lab.
Not a fun thing.

24. Material Safety Data Sheet
MSDS
Material Safety Data Sheet

25. MSDS Sheets
MSDS sheets exist for every chemical that you may use in a work area. McDonald’s even has them.
They provide information on how to handle, store, clean up, and treat for exposure.

26. Sheet Set-up
MSDS sheets are divided into 16 sections, each dealing with a certain safety concern.
For our purposes, we will focus on sections 1-8, 10 and 11.

27. Section 1
The name of the chemical and the company it came from are found here.
Company contact information is listed.
(Use your sample sheet to complete your notes.)

28. Section 2- Composition
This explains what makes up the substance, usually in chemical terms.
It may also give a common everyday use name.
(What is the common name for this substance?)

29. Section 3 - Hazards
This section provides descriptions of the chemical. (why?)
It also warns of any toxicity, including fatal dosage. It also notifies the user if the chemical is flammable or combustible.
In addition, it has quick info:

30. Section 3 - Hazards Info at a glance: (complete in your notes)
Health- ___
Flammability- ___
Reactivity - ____
Exposure - ____
Storage - ____
Scale: 0 = low hazard, 3 = high hazard
*The higher the numbers, the nastier the chemical*

31. Section 4 – First Aid (This part is really important in lab.)
This section provides information on how to treat a person that has been exposed to the chemical.
It is possible that emergency medical workers will need this section – its our job to provide it.
(How do you treat someone who has swallowed this chemical?)

32. Section 5 – Fire Fighting
Not all chemical fires can be put out with water – many chemicals react with water and could make the fire worse.
(Is it ok to use water on this chemical?)

33. Section 6 – Accidental Release
Accidental release means that the chemical has escaped from the controlled area of the lab; the general population is being exposed.
(What should you do if this chemical is accidentally released?)

34. Section 7 – Handling and Storage
Many chemicals are safe unless stored incorrectly.
Improper storage can lead to accidental mixtures, fume build up, and unstable chemicals.
(How important is it for this chemical to be stored properly?)

35. Section 8 – Personal Protection
If you must handle this chemical, read and follow the information in this section before touching the chemical.
(What safety equipment should be worn while handling this chemical?)

36. Section 10 – Stability/Reactivity
Two chemicals can be safe by themselves but harmful if you mix them.
This section provides info on what to avoid.

37. Section 11 – Toxicological Info
This is where you find out the physical effects of exposure.
It lists the effects as well as the targeted organs.
(What organ is targeted by this chemical?)

38. MSDS Information
Your work place should have MSDS sheets for all chemicals used/stored in the building. You should know where they are.
You can also use the internet to find up-to-date MSDS sheets. I suggest Flinn Scientific.
