1. SEGREGATION OF BIOMEDICAL WASTE Presenter- Arun Kumar Yadav Assistant Professor Medical Laboratory Sciences Department Sri. Sukhmani Institute of Hospitality & Management , Derabassi

2. WHAT IS SEGREGATION: SEGREGATION refers to the basic separation of the different categories of waste generated at source & thereby reducing the risk as well as cost of handling & disposal.

3. DEFINITIONS OF BIOMEDICAL WASTE : Any waste, which is generated during the diagnosis, treatment or immunization of human beings or in research activities . BMW contains infectious or other hazardous materials that may injure, infect or otherwise harm patients, their visitors, hospital staffs and the public in several ways.

4. SOURCES OF BIO-MEDICAL WASTE: Major sources Minor sources Hospitals Labs Research centers Blood banks Nursing homes Mortuaries Autopsy centers Clinics Dental clinics Cosmetic clinics Home care Institutions

5. Aim of segregation: Due to increase in population the amount of BMW generation of also increased it requires attention. It is capable of spreading disease or can be harmful to individuals. An inappropriate treatments and disposal spread infectious diseases like tuberculosis, hepatitis , enteric fever, HIV infection.

6. WASTE MANAGEMENT POLICY: Defining the various categories of waste being generated in the hospital / health care institution. Generation & collection of various categories of waste in separate containers , so that each category is treated in a suitable manner to render its harmless. Identifying & utilizing proper treatment technology depending upon the category of waste.

7. BIOMEDICAL WASTE CLASSIFICATION: General wastes Pathological Radioactive Chemical Sharps Infectious waste Pharmaceuticals

8. INFECTIOUS WASTE SPECIFICALLY ARE: Blood and blood products in a free flowing, unabsorbed state. Contaminated sharps. Laboratory wastes and Unfixed pathological tissues

9. COLLECTION OF INFECTIOUS WASTE: Infectious medical wastes must be collected at the point of generation in the appropriate color coded bags. Biohazard bags must be labeled with the international biohazard symbol and appropriate wording; “biohazard,” “biomedical waste ”or “ infectious medical waste”.

10. UNIVERSAL SAFETY PRECAUTIONS:

11. TRANSPORTATION: Transportation system should be secured with special containers and well defined route with minimum patient influx. The containers should have prominently visible label showing the type of waste it contains. Waste should be transported within the hospital by means of wheeled trolley.

12. The bags/containers containing BMWs should be lidded before transportation. Before transporting the bag containing BMWs, it should be accompanied with a signed documents , quantity and destination.

13. INCINERATOR: Incineration is the process where the combustible waste is reduced to exhaust gaseous products & the incombustible waste is reduced to ash. Incineration system uses high temp combustion under controlled conditions to convert waste containing infectious & pathological material to inert mineral residues & gases.

14. Significant reduction in waste volume and weight. The key parameter in an incinerator are – Temp. should be 900-1000 Celsius. Incinerator should have the air pollution control equipment. Expensive method and is generally used only by large establishments.

15. INCINERATORS

16. AUTOCLAVING: The autoclave process is technology for the treatment of microbiology laboratory waste, human blood or waste sharps, and anatomical waste. Autoclaving is the time-tested process of sterilization of medical waste using high temp. of 121 degree Celsius at a pressure of 15 lbs for a period of at least 1 hr.

17. Effective sterilization results in the destruction of bacteria, virus ,spores & other pathogenic organisms. Commonly used for reusable medical equipments. Autoclaving is efficient thermal disinfection process.

18. AUTOCLAVE PLANT

19. SHREDDERS: SHREDDERS are use to destroy plastic & paper waste to prevent their reuse. After autoclaving the plastic waste is sent to the shredder. The shredded waste is sold out to authorized plastic molding units.

20. This reduces the bulk of waste making transportation easy. Shredder have a set of revolving blades / sharps, which cut the waste into small pieces. The maintenance cost is high.

22. STAFF SAFETY: Proper training Personal protective clothing and equipment Immunization Medical surveillance Personal hygiene

23. HOW TO MANAGE BMW: 1. Survey of waste generated. 2. Reduction at source. 3. Collection and categorization of waste. 4. Transportation of waste. 5. Treatment of waste.

24. Do’s and Do not: Do’s Do not The used products should be segregated. Use protective gloves and apron while handling the waste. Clean spills with disinfectant. Burn plastic waste. Avoid needle stick injuries. Avoid spillage. Reuse plastic equipment.

25. CONCLUSION: Individual participation is required. Municipality and government should pay importance to disposal of waste economically. Educating and motivating oneself first is important. Thus refuse disposal cannot be solved without public education.
