This manual serves as a resource document in compliance with University of
Cincinnati (UC) Environmental Health and Safety, accreditation boards,
and various state and federal organizations (Environmental,
Occupational Health, and Safety).
Laboratories must develop written manuals which include specialized safety
procedures, respective to discipline (Allied Health, Biology, and
Chemistry), for all facets of laboratory activities.
The UC Clermont College-Science and Health Department will distribute this
to the appropriate personnel and incorporate these policies into annual
The development and revision of detailed, written procedures is essential
to establishing consistency, training personnel, and facilitating the
recognition and compliance to workplace safety.
Additionally, these protocols are integral to a defendable and demonstrable
safety program under the review of OSHA (Occupational Safety and Health
Administration) or other agencies.
An effective safety program ensures that functioning policies are
established, enforced, and effectively taught and documented.
The development and implementation of UC Clermont College-Science and
Health Safety Plan fosters a safer working environment and promotes a
reduction of laboratory accidents and injuries.

- protect the wellness and health of
students, instructors, and laboratory personnel
All courses involving biological agents must follow guidelines in the
University of Cincinnati Biological Laboratory Safety Manual, which
contains the minimum precautions and procedures required in Biosafety
Levels 1 and 2. Additional references include:

Agent Risk Group:
The biological and physical nature of human pathogens can be categorized
into risk groups (RG) based on the transmissibility, invasiveness,
virulence (i. e., ability to cause disease), and the lethality of the
specific pathogen. Risk groupings of infectious agents (RG1 through
RG4) generally correspond to biosafety levels (BL1 through BL4), which
describe containment practices, safety equipment, and facility design
features recommended for safe handling of these microorganisms. A
parallel series of animal biosafety levels (ABSL1 through ABSL4)
applies to handling of infected or potentially infected animals.
- Risk Group 1 agents are not associated with disease in healthy
human adults (ex. Bacillus subtilis, Escherichia coli K12,
adeno-associated virus (AAV)).
- Risk Group 2 agents are associated with human disease which is
rarely serious; treatment is usually available (ex. Staphylococcus aureus,
Salmonella sp., Herpes simplex viruses, Adenovirus sp.).
- Risk Group 3 agents are associated with serious or lethal human
disease; treatment may be available; low community risk (ex. Mycobacterium
tuberculosis, Bacillus anthracis, HIV).
- Risk Group 4 agents are associated with serious or lethal human
disease; treatment is not usually available, high community risk (ex. Ebola
virus, Marburg virus, Lassa virus). Not currently permitted for use at the
University of Cincinnati.
Personal Protection Requirements:
- To protect yourself from possible injury, wear safety goggles whenever
working with chemicals, burners, or any substance that may damage your eyes.

I have read and agree to follow the Biology Lab Student Agreement. I am
aware that the instructor and /or laboratory staff has the right to
report on or remove me from the laboratory if I fail to adhere to these
policies. Furthermore, I understand that my instructor may deduct
points for failure to obey these laboratory policies.
