MANAGEMENT

Assistant Professor

2. INTRODUCTION
• Hospital wastes always considered potentially
hazardous.
• Wider variety of hazardous materials are
infected material, cytotoxicdrugs corrosive
chemicals and radioactive substances.
• Major hazard is of infection.
• Rising trend of HBV and HIV infection to
community and health provider.
• Safe and sustainable method of disposal of
waste material.

3. NATURE AND QUANTUM OF HOSPITAL WASTE
 Three major categories of hospital in India

1. Outpatient clinic or dispensaries
2. Outpatient and inpatient care hospitals
3. Civil hospital Distt. hospital, nursing home,
medical college hospital etc.

4. HOSPITAL WASTE AND TERMINOLOGY
1. Hospital waste - mean bio medical waste
generated from different departments of hospital,
85% wastes non hazardous 10% infectious wastes
5% non - infectious waste.
2. Medical wastes - generated from diagnosis,
treatment or immunization of human being or
animal.
3. clinical wastes - Any wastes coming out of medical
care in hospital or other clinics and dispensaries.
4. Pathological waste - include human tissues,
organs, body parts removed during surgery or
autopsy from medical procedures.
5. Infectious wastes - includes all kind of wastes
which may transmit viral, bacterial or parasitic
diseases also include animal infectious wastes.

5. CLASSIFICATION OF HOSPITAL WASTES
1. Non hazardous 85%
2. Hazardous 15%

6. CLASSIFICATION
Non-hazardous(85%) Hazardous(15%)
Biodegradable
e.g. paper, cartons
Non-biodegradable
e.g. foils,plastic bags
Infectious (10%)
Dressing
Instruments
Organs
Laboratory waste etc.
Toxic (5%)
Radioactive waste
Chemical waste
Pharmaceutical waste

7.  Non hazardous :- General office wastes –
papers, cartons ,plastic etc.
 Kitchen waste
a. Biodegradable - peels of fruit and
vegetable skin and left over food, tea,
drugs and other natural kitchen waste
b. Non Biodegradable – Wrappings, foils,
plastic bags and other material

9. HAZARDOUS
(A) Potentially infectious
1. Dressing & swabs
2. Laboratang wastes
3. Instruments used in patient care
4. Potentially infected materials- placentas, tissues
organs etc.
5. Potentially infected animals

10. (B) Potentially toxic waste
1. Radioactive waste - Solid liquid and gases
used for diagnosis &
treatment
2. Chemical waste - They may be hazardous
toxic corrosive and
inflammable
3. Pharmaceutical waste - Surplus or expiry
date medicines

12. QUANTUM OF WASTES
 1-5 Kg./person developed countries
 1-2 Kg./person developing countries

13. HEALTH HAZARD WITH POOR HOSPITAL WASTES
MANAGEMENT
1. Injuries from sharp to hospital persons.
2. Nosocomial infection
3. Risk of infection outside hospital to waste handlers and
general public
4. Risk with hazardous chemicals and drugs to waste
handlers
5. Recycling and repacking of Disposable items
6. Infections – Infection disease – HBV, HIV

14. ROUTE OF TRANSMISSION OF INFECTION FROM
INFECTIOUS WASTES THROUGH
1. Non – intact skin.
2. Mucous membrane.
3. Inhalation of dust particles.
4. Ingestion through contaminated food and water and
unwashed hands.

16. CATEGORIES OF PERSONS EXPOSED TO RISK OF
INFECTION
1. Other patients and attainders.
2. Medical / paramedical persons.
3. Persons involved in collection and disposal.
4. Involved in cleaning instruments floor, surfaces
and washing of glass ware and linen.
5. Potential waste mixed with solid waste, entire
chain of persons involved in solid wastes
disposal.
6. Recycled and reused of unsterilised disposal
items.

17. HOSPITAL WASTE MANAGEMENT (FOR
PREVENTION OF HAZARDS)
• Cleanliness and good hygiene.
• Prevention of infection from patient to patient and
patient to other.
• Safe disposal of wastes from point of generation to
disposal place is important.

18. PRINCIPLES OF INFECTION CONTROL
1. Infection control measures
• a.) Infection control policy (ICP).
• b.) Hand washing.
• c.) Disinfections.
1. Patients Admissions.
2. Hygienic environment
3. Monitoring of infectious agents, finding the
source of infection & its preventive measures.
4. Waste reduction- select disposable and
reusable item to reduce waste.

19. BIO MEDICAL WASTE (MANAGEMENT & HANDLING )
RULES -1998
 Ministry of environment & forest notified a rule
to regulate disposal of biomedical waste
including human anatomical wastes, blood &
body fluids, medicines and glassware’s, solid
liquid and biotechnology waste from occupiers of
clinic, dispensaries, pathology laboratories, blood
bank, providing treatment/services, known as
Biomedical waste (management & Handling)
Rules -1998

23. Segregation and safe storage
•Segregation at source and safe storage is the
key to hospital waste management.
•Segregation should be carried out at the point of
generation.
•If infectious waste is mixed with other hospital
waste, the entire waste will be treated as
infectious waste.
•Incorrect categorization of waste can lead to
many problems.

24. Advantages of Segregation
•Reduces total treatment cost.
•Reduces impact of this on community.
•Reduces chance of infection among health care
worker.
