Lab Safety Tips
Most labs are relatively safe from serious hazards;
however, we should not be lulled into thinking that they are
completely risk free. Each lab has its own risks and students
should be aware of them before they start using lab facilities
or conducting experiments.
Safety must be a primary consideration for all persons working
in a laboratory. Activities have been selected for their interest
and relevance to the lecture class material as well as their
expected safety for students learning new techniques. Students
have a responsibility for learning and understanding the appropriate
safety procedures for each specific activity. Further, each
student has an obligation to consult the instructor for help
when safety procedures or instruction are not clear. The following
general procedures must be observed.
- Before beginning the first activity, familiarize yourself
with the location of the fire extinguishers, first aid kits,
safety shower, and eye wash or sink area in the laboratory.
Consult with your instructor regarding the proper operation
of this equipment. Always note any safety precautions which
are mentioned for specific experiments.
- Approved goggles or safety glasses with side shields
must be worn at all times while you or others are working
with any chemical materials or liquids which could splash
into a person's eye. Anyone not complying with this requirement
will not be allowed in the laboratory.
- Wear appropriate clothing. This includes closed-toe shoes
and some type of protective apron or lab coat if you are
working with any type of chemical.
- Work is permitted in the laboratory during regular class
periods when an instructor is present or after hours only
with permission of the instructor. Performance of unauthorized
experiments is not allowed.
- None of the following is permitted in the laboratory
at any time: application of cosmetics, smoking, eating,
or drinking.
- Dispose of all materials, including chemicals, glassware,
and plastic ware, in the correct manner as shown by your
instructor.
- Report any accident, even the most minor, to your lab
instructor.
- In case of a chemical splash of any type, flush the area
thoroughly with water for at least 15 minutes. For chemicals
in the eyes use eyewash if available, and if not, water
from a sink.
- If work is in an area other than regularly assigned lab,
you must return it to the original state before you leave
the area. Clean up all spills, and do not leave any materials
out.
- Wash hands before you leave the laboratory.
