1 Biomedical waste management By group I (KHADIJAH WALI,AQSA ANWAR,ARSHAM TORKAMAN,EBRAHIM JOOSAB,FAISAL FAROOQ and ALI SOHAIL)

2 Learning Objectives Define biomedical waste management Define biomedical waste management Classification of biomedical waste management Classification of biomedical waste management Disposal of biomedical wastes. Disposal of biomedical wastes.

3 Biomedical waste management Definition: Definition: “Bio Medical waste” is any waste, which is “Bio Medical waste” is any waste, which is generated during the diagnosis, treatment generated during the diagnosis, treatment or immunization of human beings or or immunization of human beings or animals or in research activities pertaining animals or in research activities pertaining to or in the production or testing of to or in the production or testing of biologicals and categories. biologicals and categories.

4 Healthcare waste Definition Healthcare waste (HCW) is defined as the total waste stream from a healthcare facility (HCF) Healthcare waste (HCW) is defined as the total waste stream from a healthcare facility (HCF) Two basic categories Two basic categories Healthcare General Waste (HCGW) 75-90% Healthcare General Waste (HCGW) 75-90% Healthcare Risk Waste (HCRW) 10-25% Healthcare Risk Waste (HCRW) 10-25%

5 Healthcare general waste Healthcare General Waste (HCGW) Healthcare General Waste (HCGW) Paper Packaging Paper Packaging Plastic packaging Plastic packaging Food preparation Food preparation And other items that haven’t been contaminated And other items that haven’t been contaminated

6 Healthcare risk waste Healthcare Risk Waste (HCRW) Healthcare Risk Waste (HCRW) Infectious waste Infectious waste Hazardous waste Hazardous waste Harmful to humans and environment Harmful to humans and environment

7 SOURCE OF BIOMEDICAL WASTE Biomedical waste is generated in: Biomedical waste is generated in: hospitals, nursing homes, clinics, medical laboratories, blood banks, animal houses etc. Such a waste can also be generated at home if health care is being provided there to a patient (e.g. injection, dressing material etc.) hospitals, nursing homes, clinics, medical laboratories, blood banks, animal houses etc. Such a waste can also be generated at home if health care is being provided there to a patient (e.g. injection, dressing material etc.)

8 Components Solids: Solids:  Catheters and tubes  Disposable masks and scrubs  Disposable tools  Medical gloves  Wound dressings

9 Contd… Liquids: Liquids:  Blood  Body fluids and tissues  Cell, organ and tissue cultures

10 Contd… Sharps: Sharps:  Blades (Razor or Scalpel)  Material made up glass such as cuvettes and slides.  Needles  Plastic pipettes and syringes

11 Contd… Laboratory waste: Laboratory waste:  Animal carcasses  Hazardous chemicals  Medicinal plants  Radioactive material with biological components  Supernatants  Cadavers,urine,feces and cytotoxic drug are not considered biomedical waste

12 classification

13 Classification Non hazardous: Non hazardous: approximately 75-90% of the approximately 75-90% of the biomedical waste is non-hazardous biomedical waste is non-hazardous and as harmless as any other and as harmless as any other municipal waste. municipal waste. (E.G, Plastic,Glass,Cardboared,etc) (E.G, Plastic,Glass,Cardboared,etc)

14 Classification Hazardous waste: 10-25% is hazardous and can be injurious to humans or animals and deleterious to environment. It is important to realise that if both these types are mixed together then the whole waste becomes harmful.

15 Classification and management CategoryWaste TypeTreatment and Disposal Method Category 1 Human Wastes (Tissues, organs, body parts Incineration / deep burial Category 2Animal WasteIncineration / deep burial Category 3 Microbiology and Biotechnology waste Autoclave/microwave/incineration Category 4Sharps Disinfection (chemical treatment)+/autoclaving/microwaving and mutilation shredding Category 5 Discarded Medicines and Cytotoxic Drugs Incineration/ destruction and drugs disposal in secured landfills

20 Disposal Of Wastes

21 Containers Type Container type Container type Must be appropriate to contents & regulations Must be appropriate to contents & regulations Bags – NO sharps, medicines or liquids Bags – NO sharps, medicines or liquids Sharps bins – sharps ONLY Sharps bins – sharps ONLY Other Rigid Bins – various e.g. Other Rigid Bins – various e.g. High liquid-content Clinical High liquid-content Clinical Combustible Radioactive Combustible Radioactive Special & Clinical (e.g. Cytotoxic) Special & Clinical (e.g. Cytotoxic) Waste medicines Waste medicines

22 Containers – Colour Container colour Container colour Tells other staff what is in the container Tells other staff what is in the container Tells the contractor what to do with the waste Tells the contractor what to do with the waste Can apply to both sacks and rigid containers Can apply to both sacks and rigid containers Safe for Disposal to General Waste Lab plastics Carcass, anatomical Sharps Cytotoxic

23 Disposal Procedure – Carcass Carcass or anatomical material Carcass or anatomical material Small / medium carcasses or obvious body parts Small / medium carcasses or obvious body parts Render safe first Render safe first Yellow bags or containers Yellow bags or containers Freeze prior to collection or keep refrigerated Freeze prior to collection or keep refrigerated

24 Disposal Procedure – Blood Blood or body fluids Blood or body fluids Render safe first Render safe first Including heavily soaked materials (e.g. swabs, dressings) Including heavily soaked materials (e.g. swabs, dressings) Yellow containers or heavy gauge yellow bags (only if doubled and NOT leaking) Yellow containers or heavy gauge yellow bags (only if doubled and NOT leaking) Freeze prior to collection Freeze prior to collection

25 Disposal Procedure – Sharps Sharps Sharps Including needles, scalpel blades and small pieces of glass Including needles, scalpel blades and small pieces of glass ALWAYS USE a Sharps bin ALWAYS USE a Sharps bin Do NOT overfill or shake Do NOT overfill or shake Follow H&S guidance and take care Follow H&S guidance and take care (If contaminated) autoclave when bin is full (If contaminated) autoclave when bin is full

26 Oct/Nov2006 Introduction to Biological Waste Training SessionSlide #26 Disposal Procedure – Plastics Laboratory plastics Laboratory plastics Render safe first Render safe first If non-identifiable following autoclave then non- clinical disposal [Black Bag and label “Safe for Disposal”] If non-identifiable following autoclave then non- clinical disposal [Black Bag and label “Safe for Disposal”] If identifiable still then possibly “offensive” - Orange Bag and label as for Clinical Waste If identifiable still then possibly “offensive” - Orange Bag and label as for Clinical Waste

27 Disposal Procedure – Glass Glassware Glassware Render safe first Render safe first Designated boxes – clearly labelled “Broken Glassware – Safe for Disposal” Designated boxes – clearly labelled “Broken Glassware – Safe for Disposal” Except if contains hazardous chemicals – special disposal route via Chemistry Except if contains hazardous chemicals – special disposal route via Chemistry

28 Disposal Procedure – Medicines Medicines Medicines Designated medicine bins only (usually Blue Rigid container) Designated medicine bins only (usually Blue Rigid container) Do not use containers intended for other uses (e.g. sharps bins) Do not use containers intended for other uses (e.g. sharps bins) Do not pour down the drain Do not pour down the drain Some medicines are considered to be Special Waste Some medicines are considered to be Special Waste

29 Disposal Procedure – Special I Cytotoxic Waste Cytotoxic Waste Special Waste, therefore Special Waste, therefore Packaging and labelling requirements Packaging and labelling requirements Holding locations – separate containment Holding locations – separate containment “Pre-notification” of SEPA by contractor & Special Waste Consignment Note “Pre-notification” of SEPA by contractor & Special Waste Consignment Note Extra charges Extra charges Notify Waste Manager Notify Waste Manager

30 Disposal Procedure – Special II Infectious Waste Infectious Waste Wherever possible, should be rendered safe / inactivated BEFORE leaving the lab Wherever possible, should be rendered safe / inactivated BEFORE leaving the lab If not possible then special conditions apply: If not possible then special conditions apply: Packaging and labelling Packaging and labelling Holding locations – separate containment Holding locations – separate containment “Pre-notification” of SEPA “Pre-notification” of SEPA Extra paperwork Extra paperwork Extra charges Extra charges Notify Waste Manager immediately Notify Waste Manager immediately

31 Disposal Procedure - Reminder Key points to remember: Key points to remember: Never fill sacks more than ¾ full Never fill sacks more than ¾ full Never overfill sharps bins Never overfill sharps bins Do NOT use anything that leaks Do NOT use anything that leaks Secure sacks with a plastic tie/seal bins before removing from lab Secure sacks with a plastic tie/seal bins before removing from lab Always use a Barcode Label and complete your Label Record Sheet Always use a Barcode Label and complete your Label Record Sheet Know if it is “Special Waste” & act accordingly Know if it is “Special Waste” & act accordingly Place in approved Holding Location (freezer) Place in approved Holding Location (freezer)
