BIOMEDICAL WASTE : PROPER SEGREGATION AND TRANSPORTATION

Adverse effects of improper Biomedical Waste Management is very often seen in hospitals. Mixing of segregated waste is a very common phenomenon at the hospitals. Doctors and Nurses may do proper segregation during their practice in color coded bins but during collection and transportation the handlers may transport both infectious and noninfectious and biodegradable wastes together. As a result, the total waste of the hospital comes into contact of each other and becomes Infectious. The quantity becomes so huge that it becomes impossible to treat as per norms. So utmost care has to be taken at this stage and proper training is to be given to the handlers to perform their duties with care.

Using of Hospital lift is another area where care has to be taken seriously. By lifts patients are going up and down with doctors and other staffs including canteen food. In free time by same lift BMW are transported by the handlers. Most of the time the persons push the lift button with gloves covered hand, as a result the button get contaminated. Doctors and everybody push the same button and carry the infection every where they visit.

Fine tuning at this point is needed meaning to educate the transporters to remove the gloves or use elbows to push the button. He may also take the help of the other travelers who are not waste handlers. At the same time supervisor should explain how to avoid this situation. Further more frequent hand wash in the hospitals are essential to avoid the contamination.

All the waste collection bins size should be uniform in size excepting few master bins which will make easy for the handlers to maintain well. Nurses should not have lunch or food of any kind at nursing stations and visitor also should avoid taking food in house of the hospitals for the safety of themselves. Better to have food at home after washing hand properly.

Administrator should take regular care of the instruments used in biomedical waste management  from wards to our door.

For example small economically built incinerator should not be installed in city based hospital, because they are surrounded by human habitation. Serious health hazard

may be caused to the city environment. They should opt for common disposal service provider for final disposal if the disposer is competent. The needle destroyer should be placed in a comer of the nursing station. It should be out of reach of visitors or patients. Same may be said about autoclaves also placed in a separate and safe covered area which is out of reach of the common person other than operator.

It is a known fact that all liquid wastes generated by the hospital should be treated by effluent treatment plant to protect the water bodies outside the hospitals. So before installation BOD, COD, TDS, TSS, Ph, Do and all other parameters should be considered to design the plant and system. Oxygen transfer with bio-culture is one of the very popular and economic systems in Canada and India. Diffuser Express, Colombia is one of the reputed organizations in this field. In India there are few companies including us who have done a creditable job in this field

Plant should not be placed close to canteen or in front gate of the hospital because ETP is a potential toxic plant and treat infected water so it should be in a corner that is close to final discharge point. If anybody has installed it otherwise it  is wrong and against the norms.

Wrong and wrongly placed devices are more dangerous because along with surrounding areas they are polluting the hospitals. Hospital should not hesitate to spend for sodium hypochlorite for disinfection. Rather than using locally manufactured Phenol, considering the own health hazards because most of the time the doctors and nurses spend the time in the hospital.
