Section 3.9. Infectious Medical Waste is medical
waste which is capable of producing an
infectious disease.
64CSR56
Infectious Medical Waste
Medical waste shall be considered capable of
producing an infectious disease if
(1) it has been, or is likely to have been,
contaminated by an organism likely to be
pathogenic to healthy humans,
(2) if such organism is not routinely and freely
available in the community, AND
(3) such organism has a significant probability of
being present in sufficient quantities and with
sufficient virulence to transmit disease.
Infectious Medical Waste
 Our Plan: Sterilize all bacterial,
fungal, viral and parasitic organisms
and cultured cells.
If you have any questions please
consult with Don Primerano or
Connie Berk.

•
•
•
•
•
Cultures of microorganisms & biologicals
Human blood and blood products
Pathological wastes
All Sharps (even if not contaminated)
Contaminated animal carcasses, body parts,
bedding and related wastes
• Materials (soil, water, or other debris) which
result from the cleanup of a spill of any
infectious medical waste.
• Waste contaminated by or mixed with
infectious medical waste.
Cultures and stocks of
microorganisms and biologicals
Human Blood & Blood
Products
• All human blood (wet or dried)
• Products from human blood.
Pathological Waste
• Human pathological wastes - tissues,
organs, body parts, containers of body fluids
Sharps
• Any article that can puncture or cut, and
have been used in animal/human patient
care or treatment
• Examples: needles, syringes, scalpel blades,

WV BUREAU OF PUBLIC
HEALTH LICENSE
•We received our license from the WV Bureau for
Public Health in December 2000
• This allows us to generate infectious
waste,sterilize on site and dispose of this waste in
regular trash.
• License also allows us to hire a licensed company
to remove our nonsterile infectious waste if
necessary (e.g. contaminated animal carcasses)

students and visitors
(2) Properly manage infectious waste in accordance
with WV 64-CSR-56 (the Legislative Rule)

INFECTIOUS WASTE
MANAGEMENT OVERVIEW
 PACKAGING BY INVESTIGATORS
DISPOSABLE WASTE
REUSABLE ITEMS
 DELIVERY TO ROOM 114 MEB
 STERILIZATION
 DELIVERY TO BFI
PACKAGING DISPOSABLE
INFECTIOUS WASTE
1. ORANGE BIOHAZARD BAGS MUST BE USED
BY ALL LABS FOR DISPOSABLE WASTE.
(Clear bags and red bags are not acceptable.)
2. ALL ORANGE AUTOCLAVE BAGS MUST BE
DOUBLE-BAGGED.
3. DO NOT FILL THEM MORE THAN 2/3 FULL!
4. DO NOT TIE THE BAGS CLOSED. Gather the
top and place a strip of autoclave tape around the
top. Steam must be able to enter and exit the bag.
5. ALL bags and flasks must be LABELED with
name, room number, phone number and contents.
SPECIAL PACKAGING
RULES
 Each lab must have separate containers for
contaminated broken glassware and uncontaminated
broken glassware
 Pasteur pipettes break easily and MUST be placed
into the appropriate broken glass container in each
lab and NEVER into the autoclave trash bag.
 Contaminated serological pipettes MUST be placed
into a container separate from the regular autoclave
bag, as they can puncture the bags. The separate
container will then be autoclaved.
DELIVERING DISPOSABLE
WASTE TO ROOM 114
1) A large gray bin is located in Room 114 MEB for
all unautoclaved disposable waste
2) Unlock the bin and place labeled waste bags
inside (AVAILABLE 24/7).
3) RELOCK THE BIN WHICH SHOULD BE LOCKED
AT ALL TIMES. A numbered key for the bin will
be issued to each lab at the end of this talk.
4) Waste will then be autoclaved, weighed and
placed in regular trash.
DELIVERING REUSABLE
WASTE TO ROOM 114
1. Place contaminated nondisposable items (flasks,
glass pipettes, etc) on the small cart just inside
the door of room 114.
2. Please refrain from leaving flasks there after 3
PM during working hours, or anytime on
weekends and holidays, because contaminated
waste must be secure.
3. Working hours for the autoclave room 8 AM –
4:30 PM.
STERILIZATION OF
INFECTIOUS WASTE

All infectious waste must be autoclaved for 90
minutes

Bags are then transferred to black plastic bags
in a separate location.

Sterilized reusables (glassware, etc) are placed
at the pickup point in the media kitchen.

Disposable waste is weighed and taken to the
BFI dumpster.
IN THE EVENT OF A SPILL
1. NOTIFY DR. PRIMERANO OR CONNIE BERK AS
SOON AS POSSIBLE. PHONE NUMBERS ARE
POSTED IN THE INNER MEDIA KITCHEN DOOR
AND ABOVE THE GREY BIN.
2. THERE IS A SPILL KIT LOCATED IN ROOM 113
Definitions
• Source Reduction - ways to lessen the
amount of material
– Segregation - keeping noninfectious waste out
of the infectious waste stream
– Minimization - reduce or eliminate waste at the
source
– Engineering controls - methods to reduce
quantity of waste(smaller containers)
MANAGING WASTE FLOW
The ONLY items that belong in an autoclave bag are the
ones that are contaminated with bacteria, viruses, blood
or other potential human pathogens.
IF IT IS NOT CONTAMINATED, DON’T PUT IT IN
AN ORANGE BAG.
DON’T PUT
NONINFECTIOUS ITEMS IN
ORANGE BAGS
• bubble wrap
•
paper towels, either from
drying your hands after
washing them or from
wiping down the bench
with a disinfectant
• scalpel blade wrappers
• needle wrappers
• Benchkote or any other
bench protector
•
gloves
• packaging materials such
as cardboard, Styrofoam
“peanuts”, etc.
• paper (copy paper, etc.
may be recycled in any of
the large blue wheeled BFI
bins on all floors and in
the copy room)
• pipettes
• food wrappers
• pop cans (can be recycled
in the blue bins)
PATHOLOGICAL WASTE
POLICY UNDER REVIEW
 glass slides containing fixed and embedded
tissue (human or animal) or Pap smear slides five
years or older
 paraffin blocks containing FIXED tissue (human
or animal)
 all materials used in embedding fixed tissue
such as foam pads, cassettes and paraffin
 containers with fixative for fixing tissue (human
or animal)
 unembedded FIXED tissue (human or animal)
REDUCED WASTE= LOWER COST
 We must weigh and record the weights of ALL bags
of autoclaved trash before placing them into large
black plastic bags and disposing of them into the
regular trash.
 The amount autoclaved waste determines if we’re a
small or large quantity generator and that in turn
determines the cost of our yearly permit renewal
(currently $250).
 Current rate:
$4.50 per ton (1998)
 Less waste also means lower labor cost.
WASTE GENERATION
 1998: 1,524 lbs. autoclaved trash
 1999: 2,308 lbs. autoclaved trash
 2000: 1,546 lbs. autoclaved trash
 2001:
523 lbs so far (2,092 lbs projected)
CONTAMINATED ANIMAL
CARCASSES
 We may not autoclave contaminated animal
carcasses for disposal in the regular trash
BFI/Stericycle, Inc.’s biohazardous waste unit can
be hired to pick up and dispose of animal carcasses
that are infected with human pathogens. They will
use special containers and liners to hold the
carcasses. The cost is currently 40 cents per pound
for disposal.
See Dr. Billy Howard in the Animal Facility.
Ethidium Bromide Waste
Ethidium bromide (Et Br) contaminated waste must
be segregated from all other trash by being placed
into plastic-lined containers. When those containers
are full, the plastic bags should be placed into the
EtBr labeled barrel in Room 116A (gel room) to await
pickup by a hazardous materials company.
 The cost for this service is very HIGH and is by the
pound. DON’T put film wrappers, film containers, film
cassettes or non-ethidium bromide contaminated
trash into these containers.
