What is Biomedical Waste

Bio-medical waste is defined as waste that is generated during the diagnosis, treatment or immunization of human beings and are contaminated with patients’ body fluids (such as syringes, needles, ampoules ,organs and body parts, placenta, dressings, disposables plastics and microbiological wastes).

NEED FOR BMW MANAGEMENTThe hospital waste, in addition to the risk for patients and personnel who handle these wastes poses a threat to public health and environmentHealth hazards of BMW

Extent of the problemMost countries of the world, especially the developing nations, are facing

the grim situation arising out of environmental pollution due to pathological waste

In India :three million tonnes of medical wastes generated every year and the amount is expected to grow at eight per cent annually.

4.2 lakh kg of biomedical waste is generated on a daily basis,( CPCB April2011)

Only 157 facilities to treat the same.  84,809 hospitals and healthcare facilities in India only 48,183 are using either common biomedical waste treatment

facilities or have commissioned private parties to take care of the same.

Quantum of BMW Generation & Treatment in Delhi- DPCC: No. of Health Care Establishments in Delhi : About 1900 , 10.125 Tons

BMW/day (based on the annual report for the year 2010).There are 10 Incinerators (including 3 CBWTFs), 21 autoclaves(including 3CBWTFs) and 3 microwaves operating in Delhi.

Present practice within Hospitals• Around 50% of the hospitals in the

country are dumping the BMW with Municipal garbage

• Waste is not segregated at the site

• 15000 hospitals have been served notice for acting as defaulters of these rules.

• No proper treatment options

• No regulated disposal sites

Present practices within hospitals1- Mostly dumped in the open space - Rag pickers can collect contaminated syringes, cotton, plastics, etc.

2- Burnt at dumpsites in an open environment - Incomplete - Small quantities of many organic and chlorinated organic compounds as well as pathogens survives - dispersal of dangerous diseases.

3- Landfills - Designed poorly and can pollute ground-water.

BIOMEDICAL WASTE(MANAGEMENT & HANDLING) RULES by Govt. of India , 1998Amended on 2000• Authoritative order to all the hospitals to stop the indiscriminate disposal of waste and ensure that it is treated in such a manner that it does not hamper the environment and human health.

• All the BMW to be segregated at the point of generation

Application These rules apply to all persons who generate, collect, receive, store, transport, treat, dispose, or handle bio-medical waste in any form

includes a hospital, nursing home, clinic, dispensary, veterinary institutions, and animal house, pathological laboratory, blood bank e.t.c.

Duty of Occupier

 It shall be the duty of every occupier 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.

. Segregation, Packing,   a. Bio-medical waste shall not be mixed with other wastes

b. Bio-medical waste shall be segregated into containers/bags at the point of generation in accordance with Schedule II

The containers shall be labeled according to Schedule III.

Personnel safety devicesThe use of protective gears should be made

mandatory for all the personnel handling waste.

Storage In an area away from general traffic and accessible only to authorized personnel

DO NOT store for more than 48 hours

If for any reason it becomes necessary to store the waste beyond such period take measures to ensure that the waste does not adversely affect human health and environment

Transport Transport by wheeled trolleys/containers /carts only in vehicles authorized for the purpose

They should be Easy to load and unload No sharp edges Easy to clean

Disinfect daily Trolleys ,Wheelbarrows: covered and open, Chutes:

Transportation and Storage

c. If a container is transported from the premises where bio-medical waste is generated to any waste treatment facility outside the premises, the container shall, apart from the label prescribed in Schedule III, also carry information prescribed in Schedule IV.

Treatment and Disposal

a. Bio-medical waste shall be treated and disposal of in accordance with Schedule 1, and in compliance with the standards prescribed in Schedule V

b. Every occupier, where required, shall set up requisite bio-medical waste treatment facilities like incinerator, autoclave, microwave system for the treatment of waste, or, ensure requisite treatment of waste at a common waste treatment facility or any other waste treatment facility.

Incineration

Burning of waste material in the presence of oxygen.

Waste volume reduction, destroying some harmful constituents.

Works at temperature (~ 400–700°C).

DrawbackDrawbacktoxic products like furanes and dioxins - can cause air pollution

Non-incineration methods 1 - THERMAL PROCESSES

A - Low-Heat Thermal Processes (93°C-177°C) Wet heat (steam) disinfection - autoclave ,Dry heat (hot air) disinfection - infrared heaters.

B - Medium-Heat Thermal Processes (177°C-370°C) Chemical breakdown of organic material. Reverse polymerization using high-intensity microwave

C - High-Heat Thermal Processes (540°C-8,300°C) or higher Electrical resistance, induction, natural gas, and/or plasma energy provide the intense heat ,total destruction of the waste Significant change in the mass and volume

Non-incineration methods

2 - CHEMICAL PROCESSES

Dissolved chlorine dioxide, bleach (sodium hypochlorite), peracetic acid, or dry inorganic chemicals.

To enhance exposure of the waste to the chemical agent, chemical processes often involve shredding, grinding, or mixing.

3 - IRRADIATIVE PROCESSES Electron beams,Cobalt-60, or UV irradiation.

Members: HOD’s of all department Nursing superintendent, Head nurse, Sanitary inspector Chief pharmacist, Radiation officer Supply officer, financial officer

Responsibility of WMO Responsibility of WMO

Day to day control of segregation, transport & disposal of BMW

Co-ordinate with the store officer for continuous supply of basic items for BMWM

Prepare guidelines for BMWM & distribute to all department

Prepare BMW posters to raise awareness

Responsibility of WMO (Contd…..) Responsibility of WMO (Contd…..)

Arrange training programmes on BMWM & safety measures for all categories of HCW

Co-ordinate with HOD/In-charge of Deptt. where deficiencies are pointed out

Co-ordinate with CPWD Deptt. (Civil & Electrical)

Send monthly & annual report to DPCC

• Check Segregation• Monitoring disinfection of waste on site• Availability of basic items for BMWM• Monitoring compliance of usage of facilities by HCW• Monitor level of awareness• Prepare waste audit• Liason between HOD’s, CNO’s & WMO

• Check segregation• Check labeling• Weigh the waste• Monitor final disposal of the waste• Ensure the working of incinerator• Provide monthly data of waste generated by both Hospitals

Feedback to WMOAssist in training programme

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!)

BMW Spills & Surface Disinfection

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 Compliance

Hand Washing

Steps to Effective Handwashing

Use soap & warm water. Scrub 10-15 seconds

Rinse well with fingers pointed downward.

After drying hands, turn off water using a paper towel. Discard towel in trash.

It is TIME to ACT, to prevent an epidemic waiting to happen.

Bio-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.

Conclusion

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.
