Biomedical waste management Dr. Hughbert Dkhar Nazareth Hospital Laitumkhrah Shillong
Introduction Biomedical waste : Is waste that is either putrescible or potentially infectious. May also include waste associated with the generation of biomedical waste that visually appears to be of medical or laboratory origin (e.g., packaging, unused bandages, infusion kits, etc.), as well research laboratory waste containing bio-molecules or organisms that are restricted from environmental release. Sharps are considered biomedical waste whether they are contaminated or not, due to the possibility of being contaminated with blood and their propensity to cause injury when not properly contained and disposed of. Biomedical waste is a type of biowaste .
Introduction At present - most of the hospitals/nursing homes are now equipped with latest instruments for diagnosis and treatment of various diseases. One of the most important aspect associated with hospitals is the generation of wastes and its safe management. Health care institution’s waste contains Human anatomical wastes Blood, body fluid, Disposable syringe, used bandages, surgical gloves, Blood bags/ intravenous tubes etc.
Introduction - continue The Bio-medical waste generated from various sources has become a problem and much attention is being given worldwide to find out solution of this problem. The main concern lies with the hospital waste generated from large hospitals/nursing homes as it may pose deleterious effects due to its hazardous nature. Bio-medical wastes, if not handled in a proper way, is a potent source of diseases, like AIDS, Tuberculosis, Hepatitis and other bacterial diseases causing serious threats to human health. Owing to the discussed potential threats this waste needs prime attention for its safe and proper disposal.
Definition "Bio-medical waste" means any waste, which is generated during the diagnosis, treatment or immunization of human beings or animals or in research activities pertaining there to or in the production or testing of biologicals .
BMW - Types Liquid Semisolid Solid.
BMW in general BMW is distinct from normal trash or general waste. It differs from other types of hazardous waste , such as chemical, radioactive, universal or industrial waste . Medical facilities generate waste hazardous chemicals and radioactive materials - Are normally not infectious, they require proper disposal. Some wastes are considered multihazardous , such as tissue samples preserved in formalin.
Definition of Occupier "Occupier" means a person who has control over the institution and/or its premises or any institution generating bio-medical waste, which includes : Hospital/Nursing home/Clinic/Dispensary, Veterinary institution/Animal house, Pathological laboratory Blood bank etc.
DUTY OF OCCUPIER: It shall be the duty of every occupier to take all steps to ensure that such waste is handled without any adverse effect to human health and the environment. Institution generating bio-medical waste includes Hospital, Nursing home/ Clinic/ Dispensary/ Veterinary institution/ Animal house Pathological laboratory, Blood bank etc.

Biomedical waste may be solid or liquid. Examples of infectious waste include discarded blood , sharps, unwanted microbiological cultures and stocks, identifiable body parts, other human or animal tissue, used bandages and dressings, discarded gloves, other medical supplies that may have been in contact with blood and body fluids, and laboratory waste that exhibits the characteristics described above. Waste sharps include potentially contaminated used (and unused discarded) needles, scalpels , lancets and other devices capable of penetrating skin.
Biomedical waste is generated from biological and medical sources and activities, such as the diagnosis, prevention, or treatment of diseases. Common generators (or producers) of biomedical waste include hospitals , health clinics , nursing homes , medical research laboratories , offices of physicians , dentists , and veterinarians , home health care , and funeral homes . In healthcare facilities (i.e., hospitals, clinics, doctors offices, veterinary hospitals and clinical laboratories ), waste with these characteristics may alternatively be called medical or clinical waste.
