Report
Biological and Chemical Safety in
the Microbiology Laboratory
What Do I Need to Know?
RESPONSIBILITIES IN ALL LABS:
• Think about the kinds of risks and hazards in your lab..both biological and chemical.
There are many resources and guides. See links.
• Have a plan to address the risks..implement and monitor it.
• Be sure to involve authorities at your college and at state level if required.. They are
your allies and can provide valuable and necessary assistance.
AS AN INSTRUCTOR OF MICROBIOLOGY:
• Make the rules clear and insist (from day one) that discipline and professional behavior
in the laboratory is absolutely required. Lack of rigorous discipline is often the reason
why students lapse as they may not take you seriously.
• There should be consequences for students who do not take policies seriously.
• Explain that in a microbiology laboratory, biosafety concerns add to the list of required
precautions above and beyond those in other labs at the university.
• Be a conscientious modeler of every regulation . Never take short cuts or let students
see you bending or breaking the rules– even when working alone in the lab.
OTHER CONSIDERATIONS:
• Clinical labs
• Experimentation involving human or animal subjects
• Researchers with NIH or NSF grant funding, etc.
Basic Safety
Your university has emergency response guidelines but be sure your students know what
to do if they are in your lab when something happens..rooms and buildings differ.
Describe, discuss, post information ..and have contingency plan if you are unconscious.
Chemical Safety
We all use chemicals in our labs. In the lab there should be access to a database
of MSDS information about all of them in case of accident or spill. There are
many different ways that labs and universities do this.
No eating or drinking in the lab..of
course. I don’t allow cough drops,
gum etc…anything that goes in the
mouth.
Proper footware is essential. I keep “slippers of shame” (cheap plastic clogs) for
students who forget. But they don’t forget if you are strict. Other details like pulling
back long hair is an excellent idea.
Lab coat… must be worn properly and other
considerations will be discussed.
Mouth pipetting? Goggles.
Storage of flammables.
Non denatured 200proof alcohol is also
regulated..you must keep records of usage.
Labeling of chemicals and solutions is important.
Anything normally found in
a kitchen, or thought of as
“food” needs to be labeled
otherwise.
Storage of corrosives like
strong acids and bases.
Possible exposure to chemical
powders…
All chemical waste MUST be collected, properly labeled
and sent for appropriate disposal . Yes – there are costs
associated, so less waste is to everyone’s advantage.
Waste satellite area must be set up in each room
where waste is generated. Proper labels should be
provided and guidelines for collection and disposal.
Spill kits should be
available as part of risk
assessment response
plan. Accidents
happen..plan for them.
Biological Safety
Biological Safety Cabinet..there are many types
for different applications. They are NOT the
same as a chemical fume hood.
Security and storage of stock
cultures.
Master list of cultures is
available where they are
stored. All equipment and
each room where there are
cultures being used is labeled
as BOHAZARD.
Biological waste must be disposed of properly.
Bench disinfection
HAND HYGIENE
Proper use of gloves!
Control of potential
“intruders.”
Aerosols and droplets
STUDENT AGREEMENT ON LABORATORY SAFETY
I have read the Laboratory Policy Statement of the Department of Biological and Environmental Sciences, Western
CT State University, and I understand its content. I agree to abide by all laboratory and/or field rules set forth by the
instructor.
I agree to inform the instructor, in writing, of any personal condition which may render a laboratory or field experience
unsafe for me or others prior to my participation in that laboratory or field experience. If I am at special risk for any of
the reasons explained in the policy statement, I will discuss the situation with my physician before proceeding with
the course.
I understand that my safety is entirely my own responsibility and that I may be putting myself and others in danger if I
do not abide by all the rules set forth by the instructor and/or if I do not provide relevant information as stated above.
