knowledge, this is as complete a document as can be reasonably expected, however, following
these guidelines does not guarantee that an individual may not be harmed in a lab, and because
situations can arise that are not expected and there may be guidelines that have been overlooked
by simple mistake, the College of Arts and Sciences, Dakota State University, and the author

Very rarely will an injury or accident occur in a well-supervised laboratory. When an
injury or accident does occur, it is generally brought about by complacency. In this laboratory,
you will hear a LOT about lab safety; you will be given safety instructions at the start of each
lab, you will be told of the major hazards of each chemical you will be using, and you will be
quizzed on safety. Sometimes, such an empha sis makes a student nervous about what may be a
new learning environment for them. This is an unfortunate and unintentional side effect, but it is
important to give such emphasis on safety to reduce the odds of injuries in the lab by being sure
that students know what hazards exist, how to avoid them and how to respond if something does
go wrong. Knowledge is the best defense against injury in a chemistry lab.
The best way to prevent accidents is for you to know the possible hazards of the
laboratory. Any experiment, no matter how often it has been performed in the past, has the
potential to fail with hazardous results. By knowing the hazards, you will develop a healthy
respect for what is happening around you, and with this respect, heightened levels of observation
are sure to follow. This implies that potential accidents can be spotted before they can occur. If
there is ever anything that does not seem right to you, it is not only your right, but also your
obligation to point them out to m e, your ins tructor. I will do my part to keep you safe, but I will
need your help.
The following sections present some general guidelines. These are not arbitrary rules set
down to make your life less enjoyable. Each and every one of them has a specific purpose,
which will hopefully be made clear to you. If not, ask! There will be a safety exam which you
will be required to pass (90% or greater) before the fourth lab day. Even though this grade will
not be a part of your final grade, you must pass this exam to continue in the lab, so take it
seriously. On the other hand, it is not designed to trick you or to be particularly difficult. If you...
