Ppt. presentation for training of medical staff

1. 1
BIO MEDICAL WASTE
MANAGEMENT

2. Objectives
• Minimise environmental threat and public
health risk
• Minimise hospital acquired diseases to the
medical staff and health care personnel
who handle these wastes at generation
point
• Stop recycling of disposable syringes,
saline, I.V. fluid bottles, picked up by rag
pickers and are recycled back into the
market without any disinfection

3. 3
• Doctors and nurses
• Patients
• Hospital support staff
• Waste collection and disposal staff
• General public
• Environment
Who’s at Risk ?

4. Who is responsible for Waste
management
 Doctors
 Nurses
 Technicians
 Other staffs like ward boys
 Logistics
The Bio-medical waste should be
segregated as per categories applicable.

5. STEPS FOR BIO-MEDICAL
WASTE MANAGEMENT
• Waste generator is responsible for
The steps that should be followed are:
• Segregation
• Collection and Storage
• Transportation
• Treatment and Disposal 5

6. How segregation of wastes is
to be done?
6
 Black Bucket - General waste (non infectious)
 Red Bucket - Infectious plastic waste like saline
bottles, syringes, catheters, etc
 Yellow Bucket - Anatomical and Soiled waste.
 White (Puncture Proof Container) - Metal and
Glass sharp waste like broken vials, needles etc

7. Do’s
1. Always segregate waste at source of generation
2. Segregate infectious waste into:
a. Sharps (Metal and Glass sharps) like needles, blades, lancets,
broken ampoules, vials, slides in white puncture proof
container
b. Solid wastes (Infectious plastic waste) like syringes, tubing,
catheters etc to be disposed in red plastic bins/bags
c. Anatomical waste (placenta, body parts) and soiled waste
(Items contaminated with blood, and body fluids including cotton,
dressings, soiled plaster casts, lines, beddings, other material
contaminated with blood) in yellow plastic bins/bags
d. Non-infectious (General) waste like waste similar to household
waste including packaging material, cartons, fruit and vegetable
peels, syringe and needle wrappers, medicine covers in black
plastic bins and bags
7

8. Don’ts
Never mix infectious and non-infectious waste at
source of generation, during waste collection,
waste storage, waste transportation or during
final disposal of waste.
Points to remember:-
• Bins should be located at all points of waste
generation
• No infectious waste should be stored beyond
48 hours 8

9. 9

10. COLLECTION AND STORAGE OF WASTE
Do’s
• Always collect the waste in covered bins
• Fill the bins up to the 3/4th level
• Clean the bins regularly with soap and
water/disinfect the bins regularly
10

11. Don’ts
• Never overfill the bins
• Never mix infectious and non-infectious
waste in the same bin
• Never store waste beyond 48 hrs
11

12. 12

13. TRANSPORTATION OF WASTE
Do’s
1. Always carry/transport the waste in
closed containers
2. Use dedicated waste collection
bins/trolleys/wheel barrows for
transporting waste
3. Transport waste through a pre-defined
route within the health care facility
13

14. Don’ts
1. Never transport the waste in open
containers or bags, it may spill and lead
to spread of infections
2. Never transport waste through crowded
areas

16. TREATMENT AND DISPOSAL
OF BIO-MEDICAL WASTE
• All sharp waste (Metal and Glass sharp waste) - Disinfected in their
puncture proof containers and should be disposed off in the sharps pit.
• Infected organic waste (Body/Body parts) and soiled waste (Items
contaminated with blood, and body fluids including cotton, dressings, soiled
plaster casts, lines, beddings, other material contaminated with blood)-
Should be taken to the onsite deep burial pits and covered with a layer of
lime and soil or Incinerated.
• Infected recyclables such as plastics waste - Should be first cut and then
put in the Red Bucket. It is disinfected using bleach solution (in a
disinfection tank) and then shred. It is then sent for recycling or stored for
deferred recycling.
16

17. General Waste
• Non-infected organic waste such as kitchen waste and leaf
fallings have to be put in a compost pit, which is to be located
within the premises. Standard composting methods such as
mixing the waste with leaf fallings and soil should be adopted.
Manure will be available and this should be used for the garden.
• Recyclable material such as packaging material, recyclable
plastic and paper should be sold to authorized recyclers. Plastic
should be shredded and disinfected before disposal. Care must
be taken to ensure that the recyclable waste is not infected and
also that it be kept separate from infectious waste at all times.17

18. 18

19. CHEMICAL DISINFECTION
Ensure the following points while chemical disinfection:-
• That the used product is treated prior to disposal.
• Treatment should be with a solution of 1% Bleaching
Powder (10 Gm bleaching powder in 1 liter of water)
• The waste should be submerged in this solution for an hour
• Infected waste shall not be kept for more than 48 hours and
so disinfection process shall be done every day.
19

20. SITE OF CHEMICAL
DISINFECTION
• Sharp waste – Disinfectant be placed in the PPC
• Plastic waste – Disinfection be carried out in tumbler (Sub
centre) and disinfection tank (CHC/DH)

21. HANDLING MERCURY SPILLS
• Never touch mercury with bare hands as mercury is
absorbed quickly though the skin.
• Remove all jewellery while dealing with mercury as
mercury combines with gold, silver and other metals.
• Clear the area around the spill.
• Wear all the protective gear
• Contain the spread of mercury and use two hard
cardboard sheets to gather all the mercury.
• Use a syringe to suck up mercury
• Pour contents of the syringe into the plastic/ glass
container with 5 to 10 ml of water.
• Put sealing tap, if used in the plastic/glass container.
• Put the used syringe in a separate plastic container for
further use.
21

22. • At least two pairs of latex gloves (Mercury passes
through a single pair of latex gloves)
• Face mask
• Protection for the eyes
• Sealing tape
• 10 c.c. syringe
• Covered plastic/glass container with water
Mercury containment kit
22

23. • Mercury can be stored indefinitely in this condition, but the
hospital should seek out a government approved and
licensed hazardous waste disposal firm or mercury
recycler, which can handle mercury.
• Mercury collected in this manner can be cleaned and
reused in the new equipment
Storage and disposal of mercury waste
23

24. HANDLING LIQUID WASTE SPILLS
Liquid waste is any blood, body fluid, pus, any discharge
from wounds or liquid chemicals
• Clean the liquid waste spill by adding equal or more
quantity of bleaching powder solution and leave the
area for 30 minutes
• Wipe the area with a swab/cloth
• Discard the swab/cloth after cleaning the area into the
Yellow bucket. 24

25. DISPOSAL OF DISINFECTANT
Do’s
• Always dilute the disinfectant before disposal into drains
• Wear personal protective gears while handling
disinfectants
25

26. • Never dispose the chemicals, disinfectants without diluting
them
• Never use expired chemicals or disinfectants. Send them
back to the stores
DISPOSAL OF DISINFECTANT
