Last updated: Dec. 2013
Part I: Laboratory Safety
This section of the lab will cover proper safety practices that you should observe in this course as well as
ones you take in the future.
You will watch the video Workshop Safety Series: Chemistry Laboratory during the first lab meeting. As
you watch, answer the following questions. Most questions highlight important safety rules (though
everything in this video is important, right?), but some are simply here to confirm that you actually watched
the video. Hopefully, you’re smart enough to know which is which.
Once graded and returned, you should keep this handout for future reference.
