Hospital waste is categorized as hazardous or non-hazardous. Hazardous waste includes infectious waste like human tissues, sharps that can transmit disease, and expired pharmaceuticals. Proper management of hospital waste involves segregating, collecting, storing, transporting, and treating waste. Common treatment methods are incineration, chemical disinfection, and autoclaving to reduce pathogens before waste is disposed of safely. Proper hospital waste management is important to protect staff, patients, and the environment from disease and contamination.

Biohazardous wastes are the most promising sections to manage in the present condition.There are many rules to be folowed in disposal,transportation and treatment of biohazardous waste.
The health of patients is important to hospitals making it imperative to properly dispose of biomedical waste. Having the proper biomedical waste containers is part of keeping patients safe from illnesses they could contract while in the hospital.
This PowerPoint slides are about hospital waste management in Nepal and updated according to recently updated guidelines for hospital waste management 2071.
Effective hospital waste management is paramount for both environmental sustainability and public health.
Waste Categorization: Hospital waste spans infectious, hazardous, and general waste. Proper categorization ensures safe disposal and minimizes risks.
Biohazard Containment: Safeguarding healthcare workers and the community, proper handling and disposal of biohazardous waste is crucial to prevent disease transmission.
sustainable Practices: Adopting eco-friendly methods, recycling, and reducing waste generation contribute to minimizing the environmental impact of medical facilities.
Community Well-being: Responsible hospital waste management safeguards the local environment, prevents pollution, and nurtures a healthier community.
Embracing advanced waste management strategies is a shared responsibility. It upholds ethical healthcare practices while fostering a cleaner, safer, and healthier future.

Feeding plate for a newborn with Cleft Palate.pptxSatvikaPrasad
A feeding plate is a prosthetic device used for newborns with a cleft palate to assist in feeding and improve nutrition intake. From a prosthodontic perspective, this plate acts as a barrier between the oral and nasal cavities, facilitating effective sucking and swallowing by providing a more normal anatomical structure. It helps to prevent milk from entering the nasal passage, thereby reducing the risk of aspiration and enhancing the infant's ability to feed efficiently. The feeding plate also aids in the development of the oral muscles and can contribute to better growth and weight gain. Its custom fabrication and proper fitting by a prosthodontist are crucial for ensuring comfort and functionality, as well as for minimizing potential complications. Early intervention with a feeding plate can significantly improve the quality of life for both the infant and the parents.

Health Education on prevention of hypertensionRadhika kulvi
Hypertension is a chronic condition of concern due to its role in the causation of coronary heart diseases. Hypertension is a worldwide epidemic and important risk factor for coronary artery disease, stroke and renal diseases. Blood pressure is the force exerted by the blood against the walls of the blood vessels and is sufficient to maintain tissue perfusion during activity and rest. Hypertension is sustained elevation of BP. In adults, HTN exists when systolic blood pressure is equal to or greater than 140mmHg or diastolic BP is equal to or greater than 90mmHg. The
INFECTION OF THE BRAIN -ENCEPHALITIS ( PPT)blessyjannu21
Neurological system includes brain and spinal cord. It plays an important role in functioning of our body. Encephalitis is the inflammation of the brain. Causes include viral infections, infections from insect bites or an autoimmune reaction that affects the brain. It can be life-threatening or cause long-term complications. Treatment varies, but most people require hospitalization so they can receive intensive treatment, including life support.

Hospital Waste Management
2. Hospital Waste is the waste produced
in the course of health care activities
during treating, diagnosing and
immunizing human beings or animals
or while doing study/research
activities.
75- 90% Non hazardous or General
waste
10-15% Hazardous or harmful waste
3. WHO Classification
WASTE CATEGORIES DESCRIPTION &EXAMPLES
GENERAL WASTE No risk to human health eg:
office paper ,wrapper , kitchen
waste, general sweeping etc
PATHOLOGICAL WASTE Human tissue or fluid eg: body
parts , blood, body fluid etc.
SHARPS Sharp waste
eg: Needle , scaples , knives ,
blades etc.
INFECTIOUS WASTE Which may transmit bacterial ,
viral or parasitic diseases to
human being , waste suspected
to contain pathogen
eg:laboratory culture , tissue
(swabs) bandages etc.
4. CHEMICAL WASTE Eg: Laboratory reagent ,
disinfectant ,film developer
RADIOACTIVE WASTE Eg: Unused liquid from
radiotherapy or lab research ,
contaminated glass wares
PHARMACEUTICAL WASTE Expired outdated drugs/
chemicals
PRESSURIZED CONTAINER Gas cylinder , aerosol cans
GENOTOXIC WASTE Waste containing cytotoxic
drugs (often used in cancer
therapy)
5. SOURCE OF HEALTH CARE WASTE
Governmental Hospitals
Private Hospitals
Nursing Homes
Physician’s office
Dentist office
Dispensaries

Hazardous (Infectious
&toxic waste)
Wards , Treatment
room, Dressing room
,OT, ICU , Labour room ,
Laboratory , Dialysis
room ,CT scan ,Radio-
imaging etc.
Hospital itself
8. 2.SEGREGATION
Done at point of generation of waste
and put in separate color bags . Color
coding varies from nation to nation .
For eg. In AIIMS hospital , New delhi ,
Following color code bags are
practised
12. 3.COLLECTION OF WASTE
Centralized sanitation staffs or any
other sanitation staffs should collect
the waste during morning , afternoon
or evening under the supervision of
nursing staff and sanitation
supervisior; documentation should
be done in register ; Garbage should
be cleaned and disinfected regularly.
13. 4.STORAGE OF WASTE
Waste should not be stored in the
generation area for more than a
period of 4-6 hours.
It is responsibility of
paramedic/sanitation staff to check
for segregation.
Waste collected in various areas
should be transported for
disposal/treatment.
14. TRANSPORTATION
•There should be separate corridor and lift in
hospital to carry and transport waste.
•General waste are deposited at municipal dumps.
•Waste for autoclaving and incineration are
dumped at separate site for external waste
(should have separate colored plastic bag for
these waste).
•Transportation should be done in sealed
container, sanitation supervisor should ensure for
leakage.
15. TREATMENT & DISPOSAL
•General waste should be dumped at
municipal dumping site . Sanitation officer
should be responsible for proper
coordination between municipal & hospital.
•Use of label/symbol is useful in identifying
waste for treatment . Eg: risk of corrosion
,danger of infection, toxic hazards, glass
hazards, radioactive material
18. INCINERATION
•High temperature dry oxidation process that
reduce organic and combustible waste into
incombustible matter.
•Resulting into significant reduction in waste
volume and weight.
•This process is selected to treat waste that
cannot be recycled, reused or can be
disposed in land.
20. CHEMICAL DISINFECTION
•Commonly used for treatment of liquid
infectious waste eg. Blood, urine, stool and
hospital sewage.
•Chemicals are added to waste to kill or
inactivate the pathogen it contains
21. WET & DRY THERMAL TREATMENT
•Wet thermal treatment/steam
disinfection is based on exposure if
infectious waste to high temperature and
high pressure steam similar to process of
autoclaving, inappropriate for treating
anatomical waste, chemical and
pharmaceutical waste.
•Screw feed technology: Dry thermal
treatment which waste is shredded and
heated in rotating auger. 80% volume and
20-35 weight is reduced, suitable for
infectious waste and sharps.
22. MICROWAVE IRRADIATION
•Microwave of frequency 2450MHZ and
wave length 12.24cm used to destroy the
microorganism . Water contained in the
waste is rapidly heated by microwave and
infectious component are destroyed by heat
conduction
23. LAND DISPOSAL
1.Open dumps : risk for public health
2.Sanitary landfills: designed and
constructed to prevent contamination of
soil , surface, ground water and direct
contact with public.
24. INERTIZATION
•Process of mixing waste with cement
and other substances before disposal in
order to minimize the risk of toxic
substance migrating in to surface water
or ground water and to prevent
scavenging
•Proportion of 65% waste, 15% lime,
15%cement and 5% water is used.
