Reading a Material Safety Data Sheet (MSDS)
OSHA (the U.S. Occupational Safety and Health Administration) requires that the manufacturer of all chemicals and chemical products supply a Material Safety Data Sheet for their products. An MSDS is meant to give you information that will allow you to work safely with a chemical, including any possible health effects, how to dispose of it, and what to do in emergency situations. Since you will be working with chemicals, not only in this class/lab, but quite possibly in your future jobs, you need to know how to read an MSDS.
An MSDS into sections to make it easy to find the information. Use the attached MSDS for a Hydrochloric Acid Solution to answer the following questions.
1) Section 1 identifies the chemical’s name. What other information is given in this section? (2 pts)
2) Google “Chemtrec”. What does this organization do? (1 pt)
2) Section 2 gives the chemical’s composition. Is this a full-strength product? If not, what is the % of HCl in the solution? (2 pts)
3) Section 3 tells you what the hazards are. How might you know if this solution had been spilled on a countertop? (3 pts)
What two bodily tissues are especially sensitive to HCl’s corrosive effects?
4) Section 4 describes how to give . What does the MSDS say to do if someone splashes HCl into their eyes? (2 pts)
5) Section 5 describes fire-fighting measures. HCl can decompose into what toxic gas in a fire situation?
(1 pt)
6) Section 6 tells what to do for a spill. What 2 chemicals could you use to neutralize some spilled HCl? (2 pts)
7) Section 9 describes the material’s physical properties. Why might it be dangerous to have an open glass of drinking water near an open container of HCl? (Hint: it doesn’t have anything to do with accidentally splashing the HCl.
2 pts)
8) Section 10 describes the material’s and . List 2 materials with which HCl should not come into contact: . (4 pts)
The other sections aren’t applicable to your work in the laboratory, although they might apply to a future job you have!
