Biomedical waste :

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

Need for biomedical waste management:

Need for biomedical waste management Prevent Nosocomial infections Control misutilisation of left over drugs. Minimise the risk of air, water and soil pollution directly due to waste, or due to defective incineration emissions and ash. Check the risk of infection outside hospital for waste handlers and scavengers, other peoples.

Problems associated with biomedical waste:

Problems associated with biomedical waste organism Diseases caused Related waste item Viruses: HIV, Hepatitis B, Hepatitis A,C, Arboviruses , Enteroviruses AIDS,infectious Hepatitis, Dengue, tick-borne fevers, etc Infected needles, body fluids, human excreta, soiled linen, blood, body fluids. Bacteria: Salmonella typhi , Vibrio cholerae , Clostridium tetani , Psedomonas , Streptococcus Typhoid, Cholera, wound infections, septicemia, rheumatic fever, endocarditis , skin and soft tissue infections Human excreta and body fluids in landfills and hospital wards, sharps such as needles, surgical blades. Parasites: Wuchereria Bancrofti , Plasmodium Cutaneous leishmaniasis , kala azar , malaria Human excreta and body fluids in poorly managed sewage system of hospitals

Biomedical waste management rules in india:

Biomedical waste management rules in india Ministry of Environment and Forests has revised the Bio Medical Waste (Management and Handling) Rules promulgated under the Environment Protection Act of 1986. The Rules now called the Bio Medical Wastes (Management and Handling) Rules 2011. According to the Ministry of Environment and Forests ( MoEF ) gross generation of BMW in India is 4,05,702 kg/day of which only 2,91,983 kg/day is disposed, which means that almost 28% of the wastes is left untreated and not disposed finding its way in dumps or water bodies and re-enters our system.

Categories of bmw :

Categories of bmw category Waste category (type) Category No.1 Human anatomical waste Category No.2 Animal waste Category No.3 Microbiology and biotechnology waste and other laboratory waste Category No.4 Waste sharps

PowerPoint Presentation:

WASTE CATEGORY NUMBER TYPE OF TREATMENT & DISPOSAL Category 1,2,5,6 Incineration Category 3,4,7 Disinfection by chemical treatment or by autoclaving/microwaving followed by mutilation/shredding and final disposal Category 8 Chemical treatment & discharge into drains meeting the norms notified under these rules & solid disposal in secured landfill

Differences between 2011 &1998:

Differences between 2011 &1998 These rules imply to every occupier generating BMW. Only 8 categories. Annual report format is indicated. Confusion between disposal of waste is cleared.

role of doctors, nurses, lab technicians. :

role of doctors, nurses, lab technicians. Do not dispose dressings in patients bin / Ask for disposal bags. Ensure all the plastics and gloves are cut and put into bleach solution. Ensure all used injections are cut using needle cutters. Ensure compliance of this scheme during ward visits Help patients understand the scheme. Media plates to be put in separate bleach solution.

DON’TS:

DON’TS Put the waste indiscriminately. Put wrong bags in bin. (Adhere to colour code.) Fill the bags till neck. (Waste would otherwise spill over.) Handle waste without protective clothing. Drag the bags after removal. (Bags can burst and the site could be repulsive.) Never recap the needle. (Never re-use needle without disinfection) Mix non infectious waste with infectious waste.

OUT HOUSE MANAGEMENT :

OUT HOUSE MANAGEMENT Role of Common Facilitator: To collect Bio Medical Waste from Individual Hospital every day. To transport in closed container Van safely to the Treatment plant. To erect common offsite BMWM Treatment facility in accordance with the standard prescribe BMWM Rules and approval from Pollution Control Board. To dispose various categories of Bio Medical Waste by approved techniques. To train the individual hospitals staffs regarding BMWM.

Environmental Legislation :

Environmental Legislation The Environment (Protection) Act, 1986 The Biomedical Waste (Management & Handling)Rules, 1998 The Municipal Solid Waste (Management & Handling)Rules, 2000 The Hazardous Waste (Management & Handling)Rules, 1989 The National Environmental Tribunal Act, 1995 The Air (Prevention and Control of Pollution) Act,1981
