    1. 1. Dr. SUMI NANDWANIAssociate Professor, Microbiology,E.S.I.C.-PGIMSR& Hospital, Basaidarapur, New Delhi
    2. 2. Points to be discussed ………… Overview : Definition Extent of Problem , Need, Present practices BMW Management Rules, application, duty of occupier Segregation, categories of BMW Transport & storage Treatment & Disposal Authorization, Appeal, Reporting of Accidents BMW Mx Committee Take Home Message
    3. 3. What is Biomedical WasteBio-medical waste is defined as waste that isgenerated during the diagnosis, treatment orimmunization of human beings and arecontaminated with patients’ body fluids (suchas syringes, needles, ampoules ,organs andbody parts, placenta, dressings, disposablesplastics and microbiological wastes).
    4. 4. NEED FOR BMW MANAGEMENTThe hospital waste, in addition to therisk for patients and personnel whohandle these wastes poses a threat topublic health and environmentHealth hazards of BMW Type of waste Health hazard Human / Animal HIV,HBV,HCV, Hgic fevers, cholera, waste/ Soiled salmonellosis, shigellosis, rabies, waste leptospirosis, anthrax,TB, pneumonia, septicemia Sharps HIV, HBV, HCV, Injuries Cytotoxic/ Cancer, genetic mutation, birth radioactive waste defect Chemical waste Poisonings, dermatitis, conjunctivitis, bronchitis
    5. 5. Extent of the problemMost countries of the world, especially the developing nations, are facing the grim situation arising out of environmental pollution due to pathological wasteIn India :three million tonnes of medical wastes generated every year and the amount is expected to grow at eight per cent annually. 4.2 lakh kg of biomedical waste is generated on a daily basis,( CPCB April2011) Only 157 facilities to treat the same. 84,809 hospitals and healthcare facilities in India only 48,183 are using either common biomedical waste treatment facilities or have commissioned private parties to take care of the same.Quantum of BMW Generation & Treatment in Delhi- DPCC: No. of Health Care Establishments in Delhi : About 1900 , 10.125 Tons BMW/day (based on the annual report for the year 2010). There are 10 Incinerators (including 3 CBWTFs), 21 autoclaves(including 3CBWTFs) and 3 microwaves operating in Delhi.
    6. 6. Present practice withinHospitals• Around 50% of the hospitals in the country are dumping the BMW with Municipal garbage• Waste is not segregated at the site• 15000 hospitals have been served notice for acting as defaulters of these rules.• No proper treatment options• No regulated disposal sites
    7. 7. Present practices withinhospitals1- Mostly dumped in the open space - Rag pickers can collect contaminated syringes, cotton, plastics, etc.2- Burnt at dumpsites in an open environment - Incomplete - Small quantities of many organic and chlorinated organic compounds as well as pathogens survives - dispersal of dangerous diseases.3- Landfills - Designed poorly and can pollute ground-water.
    8. 8. BIOMEDICAL WASTE(MANAGEMENT & HANDLING)RULES by Govt. of India , 1998Amended on 2000• Authoritative order to all the hospitals to stop the indiscriminate disposal of waste and ensure that it is treated in such a manner that it does not hamper the environment and human health.• All the BMW to be segregated at the point of generation
    9. 9. Application These rules apply to all persons who generate, collect, receive, store, transport, treat, dispose, or handle bio-medical waste in any form includes a hospital, nursing home, clinic, dispensary, veterinary institutions, and animal house, pathological laboratory, blood bank e.t.c.
    10. 10. Duty of Occupier It shall be the duty of every occupier of an institution generating bio-medical waste, to take all steps to ensure that such waste is handled without any adverse effect to human health and the environment.
    11. 11. . Segregation, Packing, a. Bio-medical waste shall not be mixed with other wastes b. Bio-medical waste shall be segregated into containers/bags at the point of generation in accordance with Schedule II The containers shall be labeled according to Schedule III.

    30. 30. Personnel safety devicesThe use of protective gears should be made mandatoryfor all the personnel handling waste.
    31. 31. Storage In an area away from general traffic and accessible only to authorized personnel DO NOT store for more than 48 hours If for any reason it becomes necessary to store the waste beyond such period take measures to ensure that the waste does not adversely affect human health and environment
    32. 32. Transport Transport by wheeled trolleys/containers /carts only in vehicles authorized for the purpose They should be  Easy to load and unload  No sharp edges  Easy to clean Disinfect daily Trolleys ,Wheelbarrows: covered and open, Chutes:
    33. 33. Transportation and Storage c. If a container is transported from the premises where bio-medical waste is generated to any waste treatment facility outside the premises, the container shall, apart from the label prescribed in Schedule III, also carry information prescribed in Schedule IV.
    34. 34. Treatment and Disposal a. Bio-medical waste shall be treated and disposal of in accordance with Schedule 1, and in compliance with the standards prescribed in Schedule V b. Every occupier, where required, shall set up requisite bio-medical waste treatment facilities like incinerator, autoclave, microwave system for the treatment of waste, or, ensure requisite treatment of waste at a common waste treatment facility or any other waste treatment facility.
    35. 35. Incineration Burning of waste material in the presence of oxygen. Waste volume reduction, destroying some harmful constituents. Works at temperature (~ 400–700°C). Drawback toxic products like furanes and dioxins - can cause air pollution
    36. 36. Non-incineration methods 1 - THERMAL PROCESSESA - Low-Heat Thermal Processes (93°C-177°C) Wet heat (steam) disinfection - autoclave ,Dry heat (hot air) disinfection - infrared heaters.B - Medium-Heat Thermal Processes (177°C-370°C) Chemical breakdown of organic material. Reverse polymerization using high-intensity microwaveC - High-Heat Thermal Processes (540°C-8,300°C) or higher Electrical resistance, induction, natural gas, and/or plasma energy provide the intense heat ,total destruction of the waste Significant change in the mass and volume
    37. 37. Non-incineration methods2 - CHEMICAL PROCESSES Dissolved chlorine dioxide, bleach (sodium hypochlorite), peracetic acid, or dry inorganic chemicals. To enhance exposure of the waste to the chemical agent, chemical processes often involve shredding, grinding, or mixing.3 - IRRADIATIVE PROCESSES Electron beams,Cobalt-60, or UV irradiation.

    44. 44. BMW management committee Head of the hospital : chairman Waste Mx officer (dev. and implementation plan)Members: HOD’s of all department Nursing superintendent, Head nurse, Sanitary inspector Chief pharmacist, Radiation officer Supply officer, financial officer
    45. 45. Responsibility of WMO Day to day control of segregation, transport & disposal of BMW Co-ordinate with the store officer for continuous supply of basic items for BMWM Prepare guidelines for BMWM & distribute to all department Prepare BMW posters to raise awareness
    46. 46. Responsibility of WMO (Contd…..) Arrange training programmes on BMWM & safety measures for all categories of HCW Co-ordinate with HOD/In-charge of Deptt. where deficiencies are pointed out Co-ordinate with CPWD Deptt. (Civil & Electrical) Send monthly & annual report to DPCC
    47. 47. • Check Segregation • Check segregation• Monitoring disinfection of waste • Check labeling on site • Weigh the waste• Availability of basic items for • Monitor final disposal of theBMWM waste• Monitoring compliance of usage • Ensure the working ofof facilities by HCW incinerator• Monitor level of awareness • Provide monthly data of• Prepare waste audit waste generated by both• Liason between HOD’s, CNO’s Hospitals& WMO Feedback to WMO Assist in training programme
    48. 48. BMW Spills & Surface Disinfection Proper spill handling:  Notify people in the area  Don appropriate PPE  Place absorbent material on spill  Apply appropriate disinfectant – allow sufficient contact time (30 min)  Pick up material (watch for glass – use tongs or dust pan); dispose of material into biomedical waste  Reapply disinfectant and wipe  For large/high hazard spills use 10% hypochlorite For routine disinfection of surfaces where BMW is handled, use a 1:10 solution of freshly diluted bleach or 1% hypochlorite (ethanol evaporates too quickly!)
    49. 49. Hand Washing Handwashing is the single most effective way to stop the spread of disease. Make certain that jewelry is limited to wedding rings, certain areas such as OR< C-section,Cath Lab and NBN allow no jewelry. Nails should be kept short and clean. Gloves do not replace handwashing. Hand sanitizer may be used if no visible soiling is present and the sinks cannot be readily accessed. This is in every patient room. It can also be used when the water is out of service. Inspect your hands each time they are washed. Only use hospital approved soaps and lotions, do not bring in any from home Alcohol based hand rubs at point of care Sinks and clean running water Training Compliance
    50. 50. Steps to EffectiveHandwashingUse soap & warmwater. Scrub 10-15 Rinse well with fingersseconds pointed downward.After drying hands,turn off water using apaper towel. Discard towel in trash.
    51. 51. It is TIME to ACT, toprevent an epidemic waitingto happen. Bio-medical waste programme cannot be successfully implemented without the willingness, self- motivation, and co-operation from all sections of employees of any health care setting.
    52. 52. Conclusion If we want to protect our environment and health of community we must sensitize our selves to this important issue not only in the interest of health managers but also in the interest of community.
