Non-compliance with proper hospital waste management can lead to…
- Non-compliance with proper hospital waste management can lead to…
- Serious health risks.
- Fines.
- Damage to a healthcare institution’s reputation.
Medical waste can be pathogenic & environmentally hazardous.
..
what do Non-Hazardous Waste include?
CLASSIFICATION OF HEALTH CARE WASTE (In Brief)
categories of Hazardous Wastes
- POTENTIALLY INFECTIOUS WASTE
- POTENTIALLY TOXIC WASTE
Source of Potentially Infectious waste
From patient care.
what does Potentially Infectious waste include?
what does POTENTIALLY TOXIC WASTE include?
STEPS OF WASTE MANAGEMENT
Site of Segregation
Waste should be segregated at the point of generation.
Importance of Segregation
Precautions during Segregation
Before bag closure
Bag Closure
After bag closure
Time COLLECTION & TRANSPORT INSIDE THE HOSPITAL
Waste that contains biodegradable materials: Should be collected & transported at least once a day
Why?
- To prevent the emission of odors.
- Avoid insects & rodents.
The safety containers used for sharp tools, They can remain for longer periods depending on:
- The disposal rate of this item a pins.
- The size of the can.
Precautions during COLLECTION & TRANSPORT INSIDE THE HOSPITAL
- Avoid spillage.
- Transport by trained personnel, under supervision, through designated areas.
- Do not mix the waste during transportation.
Place of storage
TEMPORARY STORAGE INSIDE THE INSTITUTION
Period of storage
TEMPORARY STORAGE INSIDE THE INSTITUTION
Criteria of the storage containers
Storing hazardous wastes in special containers are Made of a solid material & free of holes
Why?
To avoid leaking of liquids.
Storing hazardous wastes in special containers Must be clearly marked
Why?
- Indicating their contents.
- Indicating the dangers that may result from inappropriate handling.
Criteria of the storage room
The door should be…..
- Labelled.
- Equipped with a closing mechanism to Prevent patients or visitors from entering.
The storage area must be accessible for…
- Workers handling waste.
- For trolleys that transport waste alike.
The floor should be……
- Solid & impermeable to liquids.
- Well provided with a drainage channel.
Intro to TRANSPORT OUTSIDE THE HOSPITAL
“Procedures for transporting hazardous health care waste out of health care facilities”
- It is prohibited to transport hazardous wastes other than the licensed means of transport
- They must meet the following requirements
Criteria for Vehicles
TRANSPORT OUTSIDE THE HOSPITAL
Criteria of Drivers
TRANSPORT OUTSIDE THE HOSPITAL
Must be licensed & trained.
Final Disposal of Waste (In Brief)
Criteria of Routes
TRANSPORT OUTSIDE THE HOSPITAL
Aim of Mechanical Disposal
To change the physical form or characteristics of the waste to make further handling easier.
Examples of Mechanical Disposal
Indications of Mechanical Disposal
Decontaminated waste.
aim of Thermal Disposal
Use heat to destroy or decontaminate.
History of High heat system (incinerator)
Historically most commonly used by health care.
Examples of Thermal Disposal
- High heat system: temp. 600° - 5500°
- Low heat system (Steam & hot water etc: temp. < 150°
Principles of High heat system (incinerator)
Value of High heat system (incinerator)
Decrease Vol & weight by > 95%
Adv of High heat system (incinerator)
Disadvantages of High heat system (incinerator)
Types of Low heat systems (Steam sterilization)
Autoclave & Hydroclave
Principle of Autoclave
Validation test for Autoclave
Bacillus steathermophillus spores are used.
Value of Autoclave
Decrease 30% “in volume”
Advantages of Autoclave
Disadvantages of Autoclave
Principle of Hydroclave
Value of Hydroclave
Decrease 80% “in volume” & 50% “in mass”
Disadvantages of Hydroclave
- Foreign made.
- High capital cost.
Time of Chemical Disposal
Chemical disinfection of waste is required at source…
* So it is no longer a source of pathogenic organisms.
Advantages of Hydroclave
Examples of Chemical Disposal
- A good disinfectant is bleach.
Criteria of using Bleach in Chemical Disposal
The concentration prescribed by WHO is 10 gm of bleach in 1 litre water.
Medical wastes that have been chemically disinfected should ……. till careful bacteriological testing has shown disinfection to be complete.
continue to be treated as Hazardous,
Def of Disposable Items
Single use products as…
- Syringes.
- IV bottle.
- Catheters.
- Rubber gloves.
Procedure of disposal of Disposable Items
Dealing with sharps
Characters of Deep Burial
