Unformatted text preview: thes. Some of my students have, in the
Dakota State University Page 7 of 232 Safety Guidelines General Chemistry I and II Lab Manual past, brought old clothes with them in a gym bag and changed right before and after lab. Be
especially careful of sleeves around open flames..
Long hair is to be constrained. Like hanging clothes, long hair is subject to fire and
contact with chemicals. A rubber band will be used to constrain particularly long hair if
No radios, tape players, CD players or any other devices of this type will be permitted in
the laboratory at any time. Loud music is distracting, and headphones prevent you from hearing
announcements or verbal warnings given in the lab.
Take the time to identify all of the laboratory safety equipment, and keep their location in
your mind at all times. You should be able to close your eyes any time during a lab and point to
such safety equipment as the fire extinguisher, the emergency eyewash stations, the fire blankets,
the safety shower, etc. If you were to splash a chemical in your eyes, you'd better be able to find
that eyewash station without your eyes well before permanent damage can occur (which can be
seconds depending on the nature of the chemical).
Check all safety equipment. I'll keep as close an eye on it as possible, but I need your
help as well. Is the fire extinguisher charged? Does it have the plastic "seal"? Is there enough
sodium bicarbonate in case there is a chemical spill? If anything does not look right to you,
report it to your lab instructor IMMEDIATELY!
Material Data Safety Sheets (MSDS's) are available to you on request only. Basic safety
information will be given during the safety lecture before each lab. Yow can also find links for
MSDS’s on my homepage at http://www.homepages.dsu.edu/bleilr/ if you are interested.
ABSOLUTELY NO HORSEPLAY WILL BE TOLERATED IN THE LABORATORY!
Offenders of this one will be unceremoniously cast out with a zero resulting for that day's work.
I realize that at times it is awfully tempting to grab that water bottle and squirt your friends, but
many hazardous chemicals look like water. The humor will be lost if something other than water
is in that bottle.
Always read the upcoming experiments carefully and thoroughly, being sure to
understand all of the directions before entering the lab. This will help you to be prepared to
handle any hazards of the experiment, and will also help you to perform the experiment more
quickly resulting in less "fumbling around" and reckless work as you rush to finish on time. To
ensure that you have read the upcoming experiment, you are required to complete the pre- lab
Dakota State University Page 8 of 232 Safety Guidelines General Chemistry I and II Lab Manual assignment before entering the lab. If your fail to complete the pre -lab assignment on time,
you will not be allowed to perform the experiment.
Be in the lab and ready promptly...
