Health and safety of the nursing staff is cardinal feature of biomedical waste management. The Medical Superintendent or head of the institute must provide training to strengthen their skills for safety. Although biomedical waste management can't be achieved without the 1 cooperation of each and every worker and patient, the nursing personnel play a significant role in this whole process. They need to be informed about current available technology to deal biomedical wastes. The sound knowledge and safe practices among all health care staff need to be strengthened. Biomedical waste management is an important issue of concern to all healthcare personnel as inappropriate management has the potential for serious infections and noninfectious injury to patients and care providers. Inadequate management of biomedical waste can be associated with risks to healthcare workers, patients, communities and their environment. The aims and objectives of the study were to assess the knowledge, attitude and practice of health care.

All human activities produce waste. Such waste may be dangerous and needs safe disposal. Industrial waste, sewage and agricultural waste, pollute water, soil and air; it can also be dangerous to human beings and environment. Similarly, hospitals and other health care facilities generate lots of waste which can transmit infections, particularly HIV, Hepatitis B & C and Tetanus, to the people who handle it or come in contact with it.

Until fairly recently, medical waste management was not generally considered an issue. In the 1980s and 1990s, concerns about exposure to human immunodeficiency virus (HIV) and hepatitis B virus (HBV) led to questions about potential risks inherent in medical waste. Thus hospital waste generation has become a prime concern due to its multidimensional ramifications as a risk factor to the health of patients, hospital staff and extending beyond the boundaries of the medical establishment to the general population-2

Hospital waste refers to all waste, biologic or non-biologic that is discarded and not intended for further use. Medical waste is a subset of hospital waste; it refers to the material generated as a result of diagnosis, treatment or immunization or patients ana associatea oiomeaicai research. Biomedical waste (BMW) is generated in hospitals, research institutions, health care teaching institutes, clinics, laboratories, blood banks, animal houses and veterinary institutes.

Biomedical waste is the infectious waste generated from hospitals. Improper in health care management of waste generated facilities causes a direct health impact on the community, the health care workers and on the environment. The waste generated in these institutions essentially consists of solids and liquid, which may be hazardous, infectious and non-infectious. It has been estimated that up to 85% to 90% of the waste generated in hospitals is non-infectious (free with any body fluids, which is similar to domestic waste). It is the remaining 10% to 20% of waste that is of concern because it is hazardous and infectious. . In addition, waste that is unsegregated and not treated in the right manner would cause environmental pollution affecting the health of the community. From waste audits done at several hospitals by a few NGOs, arrived at some figures, which can now be used and extrapolated for the whole country. These audits must be conducted only after adequate training on waste segregation is given to health care institutions.

Health-care waste management in India is receiving greater attention due to recent regulations (the Biomedical Wastes (Management & Handling) Rules, 1998). The prevailing situation is analyzed covering

various issues like quantities and proportion of different constituents of wastes, handling, treatment and disposal methods in various healthcare units (HCUs). The waste generation rate ranges between 0.5 and 2.0 kg bed-1 day-1. It is estimated that annually about 0.33 million tons of wastes are generated in India. The solid waste from the hospitals consists of bandages, linen and other infectious waste (30- 35%), plastics (7-10%), disposable syringes (0.3-0.5%), glass (3-5%) and other general wastes including food (40-45%). In general, the wastes are collected in a mixed form, transported and disposed of along with municipal solid wastes. At many places, authorities are failing to install appropriate systems for a variety of reasons, such as non¬availability of appropriate technologies, inadequate financial resources and absence of professional training on waste management. Hazards associateci witn neaitn-care waste management ana snortcomings in tne c existing system are identified.6

The nurses spend maximum time with patients in the ward than any other member of the health team, increases their exposure and risk to the hazards present in hospital environment, mainly biomedical waste. They need to be well equipped with latest information, skills and practices in managing this waste besides reducing hospital-acquired infections to protect their own health. They are also responsible for preventing risk due to waste to the other) members of health team and community at large.

In 2006 a study conducted in medical, dental, nursing and midwifery students at the university teaching hospitals of Shiraz, Iran reported that 71.1%of the students have needle stick injuries. It has been found that one third of sharp injuries are related to disposal process. Investigator experienced that most of staff nursess had limited knowledge about bio medical waste management. So there is a need to up-to-date their knowledge and practices of bio medical waste management. So investigator felt that awareness through teaching programme is effective way for nursing students to equip themselves with latest information about skills and practices in biomedical waste management, which help them to work effectively in the hospital.
