Biosafety at ISU

Biosafety


The application of knowledge, techniques and
equipment to prevent personal, laboratory
and environmental exposure to potentially
infectious agents or biohazards.

Environmental Health and Safety
Bloodborne Pathogen
Anyone working with human blood or
other infectious agents including mammalian
cell lines must be enrolled in the bloodborne
pathogen program and take bloodborne
pathogen training annually.

Details about the program can be found
in the Bloodborne Pathogens manual which
is on the EH&S website.

Environmental Health and Safety
Biohazardous Waste Oversight
All biohazardous waste should be
decontaminated before disposal.

Be sure to place an “X” over the
biohazard symbol on biohazard bags before
placing them in the autoclave.


Environmental Health and Safety
Waste Disposal


All biohazardous waste must be
disposed of according to the ISU
Sharps and Biohazardous Waste
Policy.
Decontamination or
disinfection

Environmental Health and Safety
Sharps Safety
Dispose of sharps in a puncture resistant
container.

Do not throw sharps, including plastic
pipettes, into the trash.

Environmental Health and Safety
Biosafety Cabinets (BSCs)
EH&S coordinates the annual certification
of biosafety cabinets.

All BSCs used with infectious substances
must be certified annually.

EH&S offers training on how to properly
use BSCs.

Autoclave Validation
EH&S provides autoclave validation
testing (spore vials).

EH&S offers training on how to safely and
effectively use autoclaves.

Environmental Health and Safety
Biological Materials Inventory
A resource for first responders (think
firemen) to identify the location of
potentially infectious materials in an
emergency.

Online database with intuitive data entry
tools. Call EH&S 294-5359.

Environmental Health and Safety
Laboratory Equipment Disposal

Disposed of through ISU Asset Recovery.
All laboratory equipment must be
inspected and approved for disposal by
EH&S, call 294-5359.

Environmental Health and Safety
Biohazardous Materials
Definition- Materials of biological origin
that could potentially cause harm to
humans, domestic or wild animals, plants
or the environment.
12
Environmental Health and Safety
Examples

Transgenic animals or plants

Human, animal or plant pathogens

Biological toxins (such as botulinum toxin)




Bioterrorism use or
biological warfare
 Bacteria: i.e.
Anthrax
Agroterrorism
 Plant
 Livestock
14
Environmental Health and Safety
Regulations
Regulations and requirements
depend on the type of
biological agent used in the
research.
