The document discusses biomedical waste management, defining biomedical waste as materials generated during medical activities, which can be hazardous. It outlines the aims of biomedical waste management, sources of waste, classification of healthcare waste, and the health and environmental risks associated with improper disposal. Additionally, it details the rules and guidelines for handling and disposing of biomedical waste in India, including treatment methods and penalties for non-compliance.

2. Definition
Biomedical waste means any waste materials which is
generated during diagnosis, treatment, surgery or
immunization of human beings or animals or research
activities pertaining there to or in production of biologicals.

21. How did BMW come into Existence
• In the late 1980’s
• Items such as used syringes washed up on several
East Coast beaches USA
• Concern about HIV and HBV virus infection
• Lead to development of Biomedical Waste
Management Law in USA.
• However in India the seriousness about the
management came into lime light only after 1990’s

22. Legislation
• Recognizing the deadliest nature of the Bio-Medical Waste, the
Government and Pollution Control Boards under the guidelines
of Ministry of Environment and Forests(MOEF).
• MOEF have promptly designed and issued guidelines to the
hospitals to ensure a proper and safe disposal of bio-medical
waste
• BIO-MEDICAL WASTE Management & Handling Rule came into
effect in 1998.
• Provides uniform guidelines and code of practice for Bio-
medical waste management.

23. Biomedical Waste
Management and Handling Rules, 1998
[Amended in 2000]
• These rules apply to all persons who generate, collect,
receive, store, transport, treat, dispose or handle bio-
medical waste in any form. All Institutions generating
BMW must take all steps to ensure that such waste is
handled without any adverse effect to human health and
the environment

24. Penalties as per rules
• The PENALTIES are as specified in Environment
(Protection) Act 1986.
• Imprisonment for upto five years with fine upto one lakh
rupees, or both.
• In case the failure additional fine upto five thousand
rupees for every day.

the infectious waste stream
• Minimization - reduce or eliminate waste at the
source
• Engineering controls - methods to reduce quantity
of waste(smaller containers)

32. Steps to Manage Hazardous Wastes
before Disposal
1. Know what hazards you have.
2. Purchase smallest quantity needed, and don’t purchase
hazardous materials if safe alternative exists
3. Limit use and access to trained persons with personal
protective gear
4. Use Engineering Controls such as Ventilation, Hoods
etc.
5. Get Rid of Unnecessary Stuff

33. 6. Label of Hazard Warnings

34. 7. Communicate about Work -place
Hazards
• Job description
• Posters on doors
• Labels on hazards
• Give feedback on use of
PPE and disposal in
evaluation
• Role model safe use and
disposal
• Contact point who is
responsible

35. 8.Label for bio-medical waste containers/bags

36. Segregation of waste
At the point of generation

In kerala, IMAGE ( Indian Medical Association Goes Eco-
Friendly) is the external agency managing final disposal
of hospital wastes…

53. Indian medical association goes eco-friendly
Indian Medical Association, Kerala State Branch,
established IMAGE, Biomedical Waste Treatment
and Disposal Facility at Palakkad and it was
commissioned on the 14th December 2003. IMAGE
was conceived and launched to support healthcare
providers to overcome the challenges posed by the
responsibilities laid down in the Biomedical Waste
(Management and Handling).

54. Office Bearers:
• IMAGE is guided by a team of professional doctors,
elected from among the members of I.M.A Kerala State
Branch, dedicating their knowledge in the field of
medicine and the hazards posed by bio medical waste.
• The Supreme Court judgment in December 2002 to
dispose the medical waste within 48 hours of generation
forced doctors engaged with IMA in Kerala chapter to
find out a solution.

57. Accident reporting
