Why Is Biological Safety Important?
Biological Safety
•
Use of hazardous biological materials on campus including
– Biohazardous agents and bloodborne pathogens
•
Bloodborne Pathogens
•
Prevent disease in personnel
•
Prevent release of organisms/agents into environment

Biological Safety
What are BioHazardous Materials?
•
Any biological material capable of causing harm to humans,
animals, plants
•
BioHazardous Agents – Pathogens that can replicate & cause
disease include:
– Bacteria (Streptococcus pyogenes)
– Fungi (Candida, Histoplasma)
– Viruses (HIV, HBV)
– Prions (CJD)
– Parasites (Giardia, Strongyloides)
•
Toxins – Microbial poisons
– Exotoxins – produced by bacteria
• Clostridium botulinum - food poisoning, one of most deadly
• Clostridium tetanii – tetanus
• Corynebacterium diphtheriae – diptheria
• Bioterrorism use
– Endotoxins – released from cell wall when bacteria disintegrates

Biological Safety
Classification System For Biohazardous Materials
BioSafety Levels (BSL)
Risk Group 1
BSL 1
Agents not associated with disease in
healthy adult humans
Risk Group 2
BSL 2
Agents associated with human disease;
rarely serious; preventative or therapeutic
resources available
Risk Group 3
BSL 3
Agents associated with serious or lethal
human disease; preventative or therapeutic
resources available
Risk Group 4
BSL 4
Agents likely to cause serious or lethal
human disease; no preventative or
therapeutic resources available

Biological Safety
What are Bloodborne Pathogens?
•
Microbial agents transmitted by the blood and bodily fluids of
infected individuals.
•
Control of Occupational Exposures to Bloodborne Pathogens
•
29 CFR 1910.1030
•
http://www.osha.gov/SLTC/bloodbornepathogens/index.html
15
Biological Safety
Exposure Control Plan
•
All laboratory supervisors, faculty & principle investigators are
responsible for insuring their employees and students comply
with the Exposure Control Plan to reduce the risk of occupational
exposures to bloodborne pathogens.
•
All personnel that have the potential to be exposed to bloodborne
pathogens MUST be trained to this plan.
•
A copy of the Exposure Control Plan must be readily available in
each work area or laboratory where bloodborne pathogens
exposures exist.

Where to Get More Information
www.osha.gov/SLTC/bloodbornepathogens/index.html
•
Workers in many different occupations are at risk of exposure to
bloodborne pathogens, including Hepatitis B, Hepatitis C, and
HIV/AIDS.
•
In 1991, OSHA issued the Bloodborne Pathogens Standard to
protect workers from this risk.
•
In 2001, in response to the Needlestick Safety and Prevention Act,
OSHA revised the Bloodborne Pathogens Standard, 29 CFR
1910.1030.
•
The revised standard clarifies the need for employers to select
safer needle devices and to involve employees in identifying and
choosing these devices.
•
The updated standard also requires employers to maintain a log
of injuries from contaminated sharps.

Biological Safety
•
Prevention of Exposures to Bloodborne Pathogens (BBP):
– Exposure to human blood and bodily fluids can result in
transmission of several bloodborne illnesses, including HIV and
Hepatitis B.
– This training presentation will aid in increasing awareness of the
risk of exposure to bloodborne pathogens and techniques and
practices for preventing exposure and abating hazards in
Engineering laboratories and facilities.
