What is Biomedical Waste?What is Biomedical Waste?Bio-medical waste" means any waste, which is generated during the diagnosis, treatment or immunisation of human beings or animals or in research activities pertaining thereto or in the production or testing of biologicals, and including categories mentioned in Schedule I;
Biologicals" means any preparation made from organisms or micro-organisms or product of metabolism and biochemical reactions intended for use in the diagnosis, immunisation or the treatment of human beings or animals or in research activities pertaining thereto;
Specific to hospitals Bio-medical waste is defined as waste that is generated during the diagnosis, treatment or immunization of human beings and are contaminated with patient’s body fluids (such as syringes, needles, ampoules ,organs and body parts, placenta, dressings, disposables plastics and microbiological wastes).
What is Biomedical Waste?
Waste Sharps eg: Needles Discarded medicines
Human anatomical waste Solid waste eg: cotton swabs
Who’s at Risk ?
• Doctors and nurses
• Patients
• Hospital support staff
• Waste collection and disposal staff
• General public and
• the Environment

>95,000 hospitals and healthcare facilities in India .4.2 lakh kg of biomedical waste is generated on a daily basis.Three million tonnes of medical wastes generated every year. Expected to grow 8% annually.2,91,983 kg/day BMW 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.Karnataka tops the chart with 62,241 kg/day of BMW.

Present practice within many of the HospitalsPresent practice within many of the Hospitals•Around 40% of the hospitals in the country are dumping the BMW with Municipal garbage
•Waste is not segregated at the site
• 3585 hospitals have been served notice for acting as defaulters of these rules.
•No proper treatment options
•No regulated disposal plan/sites
BIOMEDICAL RULES 1998The Government of India as contemplated under Section 6,8 and 25 of the Environment (Protection) Act,1986, has made the Biomedical Wastes (Management & Handling) Rules, 1998.
The rules are applicable to every institution generating biomedical waste which includes hospitals, nursing homes, clinic, dispensary, veterinary institutions, animal houses, laboratory, blood bank. The rules are applicable to all persons who generate, collect, receive, store, transport, treat, dispose, or handle bio medical waste in any form.
BIOMEDICAL WASTE(MANAGEMENT & HANDLING) BIOMEDICAL WASTE(MANAGEMENT & HANDLING) RULES by Govt. of India, 1998RULES by Govt. of India, 1998
Revised in 2011Revised in 2011Now known as BMW Rules, 2011Now known as BMW Rules, 2011
2011 1998Every occupier generating BMW, irrespective of the quantum of wastes comes under the BMW Rules and requires to obtain authorisation
Occupiers with more than 1000 beds required to obtain authorisation
Duties of the operator listed Operator duties absentTreatment and disposal of BMW made mandatory for all the HCEs
Rules restricted to HCEs with more than 1000 beds
A format for annual report appended with the Rules
No format for Annual Report
Form VI i.e. the report of the operator on HCEs not handing over the BMW added to the Rules
Form VI absent
Duty of the Occupier
It is the duty of every occupier i.e. head of an institution generating bio-medical waste, to take all steps to ensure that such waste is handled without any adverse effect to human health and the environment.
Provides training to HCW engaged in handling BMW
Duty of the OperatorThe operators now have to ensure that the BMW is collected from all the HCEs and is transported, handled, stored, treated and disposed in an environmentally sound manner. The operators also have to inform the prescribed authority in form VI if any HCEs are not handing the segregated BMW as per the guidelines prescribed in the rules.
Setting up BMW treatment facilityOccupier set up adequate treatment facilities like autoclave / microwave / incinerator / hydroclave, shredder prior to commencement of its operation or ensure that the wastes are treated at a common bio medical waste treatment facility or an authorized waste treatment facility.
The new Rules have omitted incinerator as one of the pre requisites for on-site treatment of BMW. The omission is owing to the various environmental impacts of incineration.
Promotion of new technologies for treatment and disposal of waste
Deep burial for disposal of BMW has also been removed from the Rules. The Rules says it can be an option only in rural areas with no access to CTF with prior approval from the prescribed authority.

Dos and DonDos and Don’’tsts
Do’s The used product should be segregated The used product should be mutilated.
The used product is treated prior to disposal. Use protective gear when handling waste Collect waste when the bin is 3/4 the full Clean spills with disinfectant Use trolleys & do not drag waste bagsDo not Reuse plastic equipment. Mix plastic equipment with other wastes. Burn plastic waste. Avoid needle stick injuries Avoid using common lift to move waste Avoid spillage

BMW Spills & Surface DisinfectionBMW Spills & Surface Disinfection Proper spill handling:– Notify people in the area– Don appropriate PPE– Place absorbent material on spill– Apply appropriate disinfectant – allow sufficient contact time (30
min)– Pick up material (watch for glass – use tongs or dust pan); dispose
of material into biomedical waste– Reapply disinfectant and wipe– For large/high hazard spills use 10% hypochlorite For routine disinfection of surfaces where BMW is handled, use
a 1:10 solution of freshly diluted bleach or 1% hypochlorite (ethanol evaporates too quickly!)
Hand WashingHand Washing Handwashing is the single most
effective way to stop the spread of disease.
Make certain that jewelry is limited to wedding rings, certain areas such as OR< C-section,Cath Lab and NBN allow no jewelry. Nails should be kept short and clean.
Gloves do not replace handwashing. Hand sanitizer may be used if no visible soiling is present and the sinks cannot be readily accessed. This is in every patient room. It can also be used when the water is out of service.
Inspect your hands each time they are washed. Only use hospital approved soaps and lotions, do not bring in any from home
Alcohol based hand rubs at point of care Sinks and clean running water Training
Steps to Effective HandwashingSteps to Effective Handwashing Thorough hand washing
after any procedure involving nursing care or close contact with the patient is essential.
Alchol based hand antiseptics gaining importance where washing with water and soap are not practicable.

ADRESSING THE ISSUES
1. Need to build-up of a comprehensive system, address responsibilities, resource allocation, handling and disposal
2. This is a long-term process, sustained by gradual improvements.
3. Specific personnel need to be assigned to monitor the bio-medical waste management in the hospital.
4. Man power needs and other resources for the BMWM of hospital to be addressed.
5. Quality assessment of bio-medical waste management should be done from time to time.
71
ADRESSING THE ISSUES- continued
6. Segregated collection and transportation – need for Non-ambiguous color coding and labeling of wastes.
7. Clear directives in the form of a posters and notice to be displayed in all concerned areas in English and local languages.
8. Safety of handlers is a big concern that is still not addressed adequately.
9. Raising Awareness about risks related to health-care waste; training staff & Waste handlers on safe practices.
10.Selection of safer & environmentally friendly management options, to protect people from hazards when collecting, handling, storing, transporting, treating or disposing waste.
7272
ADRESSING THE ISSUES
11.Issue of all protective clothing such as, gloves, aprons, masks etc. to all HCW & Waste handlers.
12.Regular medical check-up (half-yearly) of staff associated with BMWM.
13.Maintenance of Record registers for this purpose.
14.Containers should be robust and leak proof
15.Tracking of Bio Medical Waste up to point of Disposal.
16.Proper treatment and final disposal.
ConclusionConclusionBio-medical waste programme cannot be
successfully implemented without the willingness, self-motivation, and co-operation from all sections of employees of any health care setting.
If we want to protect our environment and health of community we must sensitize our selves to this important issue not only in the interest of health managers but also in the interest of community.
