Laboratory Safety Information for Students
Working in the lab can be enjoyable, but there are also risks to be aware of. The goal of this chapter is to
familiarize you with the hazards of the lab so that you can get your work done in a timely manner, avoid
damaging expensive equipment, and most importantly avoid injuring yourself. These labs are a chance to
gain practical experience to complement the knowledge you are gaining in your coursework. Part of that
practical experience is learning how to safely work in a laboratory setting. Safety is important whether
you are new to the lab, or an experienced scientist. The primary goal is to teach you how to avoid
accidents, as well as what to do when they happen. Learning good habits now is much easier than having
to correct bad habits later.
There are many different general types of hazards in the lab. Some rules apply to general lab work while
others are more specific. The first rule is to ask questions. It is better to avoid injury by asking for help
before you get into trouble. If you are unsure of a procedure and what its hazards are, ask your instructor
for help. Your instructor is there to guide you in both the experiments in the lab and in the safety
protocols. For every lab, make sure you understand or ask about the following issues:
1. Are the chemicals used hazardous? If yes, in what manner (toxic, carcinogenic, ignitable,
reactive, corrosive)?
2. What personal protective equipment should I use? (Remember, safety glasses should always be
worn!)
3. What is the safest way to handle the materials used in this laboratory?
4. What should I do if something is spilled?
5. What do I do if I spill a chemical solution on myself? Where are the safety shower and eye wash?
6. Are there any specific instructions I need to know before using the equipment required in this
lab?
7. What do I do with any waste materials generated in this lab?
General lab protocols
Many things can be done to make the most of your time in lab. The first is to prepare for the lab ahead of
time. Read the material and think about the lab before you begin to work. Making a mental plan of what
you will be doing in the laboratory that day can save time and injury in the long run. While you are in the
lab, be sure to keep in mind general hazards. Glassware is delicate and easily broken. Wet floors will be
slippery. Anything in a flame of a burner will stay hot long after it is removed from the flame. By
staying aware of your surroundings you will avoid many common accidents.
The laboratory is inherently dangerous. Eating, drinking, mouth pipetting, and horseplay are not allowed.
While you may get away with these habits for a time, they are not safe. Many chemicals are not acutely
toxic, but extended low-level exposures have health effects. Eating and drinking in the lab can lead to
unintentional poisoning. For the same reasons, food should not be stored, cosmetics should not be
applied, and contact lenses should not be handled in the lab. Horseplay in a lab situation is incredibly
dangerous. You may feel you are in control of the situation, but you do not know what the person next to
