64CSR56Infectious Medical Waste www.state.wv.us/csr/docs/WPDocs/64-56.wpd Section 3.9. Infectious Medical Waste is medical waste which is capable of producing an infectious disease.

64CSR56Infectious Medical Waste • Medical waste shall be considered capable of producing an infectious disease if • it has been, or is likely to have been, contaminated by an organism likely to be pathogenic to healthy humans, • if such organism is not routinely and freely available in the community, AND • 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.

TYPES OF INFECTIOUS WASTE • 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, razors, forceps

Animal Waste • Contaminated animal carcasses, body parts, animal bedding known to have been exposed to infectious agents during research

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)

MEB INFECTIOUS WASTE MANAGEMENT PLAN • OBJECTIVES: • Provide a safe environment for faculty, staff, students and visitors • Properly manage infectious waste in accordance with WV 64-CSR-56 (the Legislative Rule)

MEB INFECTIOUS WASTE MANAGEMENT PLAN • Handling of infectious waste (packaging, sterilization, storage and removal) • Transportation of infectious waste • Contingency plan • Training • Management plan summary

INFECTIOUS WASTE MANAGEMENT OVERVIEW • PACKAGING BY INVESTIGATORS • DISPOSABLE WASTE • REUSABLE ITEMS • DELIVERY TO ROOM 114 MEB • STERILIZATION • DELIVERY TO BFI

PACKAGING DISPOSABLE INFECTIOUS WASTE • ORANGE BIOHAZARD BAGS MUST BE USED BY ALL LABS FOR DISPOSABLE WASTE. (Clear bags and red bags are not acceptable.) • ALL ORANGE AUTOCLAVE BAGS MUST BE DOUBLE-BAGGED. • DO NOT FILL THEM MORE THAN 2/3 FULL! • 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. • 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 • A large gray bin is located in Room 114 MEB for all unautoclaved disposable waste • Unlock the bin and place labeled waste bags inside (AVAILABLE 24/7). • 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. • Waste will then be autoclaved, weighed and placed in regular trash.

DELIVERING REUSABLE WASTE TO ROOM 114 • Place contaminated nondisposable items (flasks, glass pipettes, etc) on the small cart just inside the door of room 114. • Please refrain from leaving flasks there after 3 PM during working hours, or anytime on weekends and holidays, because contaminated waste must be secure. • 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 • 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. • 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.

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) DON’T PUT NONINFECTIOUS ITEMS IN ORANGE BAGS

PATHOLOGICAL WASTEPOLICY 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.

BLOOD AND BLOODBORNE PATHOGEN RULE • Bloodborne pathogens are organisms carried in human blood that cause disease, includes bacteria and viruses like HBV and HIV • OSHA requires that we have an Exposure Control Plan

BLOOD AND BLOODBORNE PATHOGEN RULE • Universal Precautions: Treat all human blood and byproducts as if it is contaminated

BLOOD AND BLOODBORNE PATHOGEN RULE • No eating, drinking, smoking, applying cosmetics or contact lenses in the labs • No mouth pipetting; use pipetting device • Proper disposal (bleach and autoclave) • Protective clothing appropriate to the level of risk and use of barriers to exposure

BLOOD AND BLOODBORNE PATHOGEN RULE • Report exposures to Don Primerano • Sets in motion option to be tested for HIV

WE NEED YOUR FEEDBACK • THE WASTE MANAGEMENT SYSTEM IS NEW (= NOT PERFECT) • YOUR QUESTIONS, COMMENTS AND SUGGESTIONS ARE WELCOME • DON’T FORGET TO YOUR KEYS
