MEMO 54: CNSM BIOHAZARD CONTROL PROGRAM
CNSM BIOHAZARD
PROGRAM -- The CNSM
Biohazard Control Program is based on the "CDC/NIH Guidelines for Biosafety in Microbiological and Biomedical
Laboratories". These guidelines
indicate the Biosafety Level (BSL) for each microbial
agent; the levels range from 1-4. The Biosafety Level dictates the use of certain lab practices,
techniques, safety equipment and facilities.
BSL-1 organisms normally do not cause disease in healthy humans (e.g.
Penicillium); BSL-2 agents are associated with
human disease (e.g. Cryptococcus neoformans, Shigella, any human body fluid, etc.); BSL-3 agents may
cause serious or possibly lethal disease, with a potential for aerosol
transmission (e.g. HIV, Yellow fever virus, etc.); BSL-4 agents pose a high
risk of aerosol transmitted laboratory infections and life-threatening disease
(e.g. Ebola virus). Please note that
Level 4 organisms are not permitted in the College, and Level 3 organisms may
not be brought onto College property without prior written permission from the
CNSM Safety Committee. The CDC/NIH
Guidelines are available for review in the CNSM Safety Office (PH3-018); many faculty also possess their own copies.
The purpose of the CDC/NIH Guidelines is to protect students, employees
and the general public from exposure to biohazardous
materials. If you work with biohazardous materials, you should ensure that everyone in
your program is trained and that the CDC/NIH Guidelines will be observed as
appropriate. For example, the SAFE WORK
PRACTICES listed below must be consistently followed to reduce the likelihood
of exposure when using biohazardous agents:
·
Avoid hand to face contact, and don’t use sharps
unless you must.
·
Handle needles & sharps (pasteur
pipets, slides, capillary tubes, broken glass, etc..) carefully.
Engineered sharps protection must be used when working with human blood.
·
Dispose of sharps in the final container (needles
into red needle boxes only; call the CNSM Safety Office x55623 for pick-up and
disposal when full).
·
Disposal containers for sharps must be rigid; never
use bags.
·
No recapping, bending, or breaking of needles.
·
Wash hands after handling biohazardous
materials, even when gloves were worn
·
Develop and use a method of decontamination based on
surfaces and type of contamination.
·
Employ Universal Precautions: treat all human body fluids as infectious for
HIV (see "Special Biohazards" on next page for more information).
ENGINEERING CONTROLS must be used whenever appropriate; examples include
biological cabinets, mechanical barriers, needle boxes, etc. If a biological cabinet is required per the
CDC/NIH guidelines, it must be certified according to OSHA's
Title 8, CCR 5154.1(a).
Ensure that everyone concerned
uses PERSONAL PROTECTIVE EQUIPMENT (PPE) when
needed to shield skin, clothing and mucous membranes from
contact with infectious materials. The
PPE must be appropriate and fit properly; consider:
·
types of fluid or tissue involved
·
potential exposure volume
·
probable route of exposure e.g. eyes via splash; if
the potential for a splash to the eye exists, properly fitting and fully
enclosed, indirect vented chemical splash goggles must be worn
·
working conditions e.g. aerosol production might
require biological cabinet use
Don't forget to STERILIZE YOUR WASTE but WATCH OUT - DON'T USE RED
BAGS! Red bags are designated for Medical Waste collection only. If you use the orange biohazard bags, either
use autoclave tape prior to autoclaving, or write "sterilized" on the
bag after autoclaving to indicate the safe status of the bags to those who
handle regular trash. Remember,
NEVER put sharps in trash bags of any kind; always use rigid containers such as
cardboard containers or the free sharps containers provided by the CNSM Safety
Office.
HOUSEKEEPING is another important issue for biohazard areas - keep your
area clean. OSHA's
general sanitation laws in Title 8, section 3362, state that the workplace must
be clean and sanitary, and be in a condition not liable to give rise to harmful
exposure. Make sure corridors and
eyewash/shower units are not blocked.
SPECIAL
BIOHAZARDS:
MEDICAL WASTE: If you or those you supervise immunize
animals or work with human tissues or human blood-derived products, you produce
medical waste. If you perform research
pertaining to the diagnosis, treatment or immunization of humans or animals,
you are probably producing Medical Waste.
Medical waste may NOT be autoclaved and/or disposed of on campus
property. The regulations for the
collection and disposal of medical waste are quite stringent; improper handling
could result in serious fines from the City of
BLOODBORNE PATHOGENS: If you or those you supervise (including
students) work with any human tissue or fluid - except urine, saliva or cheek
cells - your work is regulated by the Cal/OSHA bloodborne
pathogen standard. Improper handling
could result in serious fines from the city of
PLEASE NOTE:
YOU MUST CONTACT THE CNSM SAFETY OFFICE BEFORE
WORKING WITH ANY HUMAN TISSUE, BLOOD OR BLOOD-DERIVED PRODUCTS, OR BODY FLUID
OTHER THAN URINE OR SALIVA.
