PMSB CONSUMABLES

Consumables are supplied to all hospital site. They must be used correctly and not

misused.

Nursing and clinical staff responsibilities:

• Segregation at SOURCE: Clinical Waste correctly segregated from General Waste.• ONLY CW is deposited in yellow bags.• ONLY SHARPS in sharps container.• Seal bags when 3/4 FULL using cable ties. Never seal bags by stapling.

WASTE SEGREGATION: DOS & DON’TS

Waste Cat. A, C, D, & E throw into yellow bags.

Infectious waste, do prior treatment by autoclave & throw into blue bags.

Waste Cat. B throw into Sharp containers. Sharp containers are firmly pressed prior to

disposal. Don’t force needle/syringes into the sharp

container.

WASTE SEGREGATION: DOS & DON’TS

Oops!! I terr..throw clinical waste into the black bag….

What should I do?

WASTE SEGREGATION

If clinical waste and domestic

waste are mixed, it should be treated as schedule waste…

Clinical Waste + Domestic Waste Clinical Waste

CLINICAL WASTE GUIDELINE…

WASTE SEGREGATION

• Place contaminated waste bag into another bag of the correct color

(yellow bag).• Under no circumstances should

incorrectly segregated waste be taken out of a waste bag or container once

deposited.

CLINICAL WASTE GUIDELINE…

MANUAL HANDLING OF CLINICAL WASTE BAG

Check if it is properly sealed. Check label and ensure it shows the source of

waste. Pick the bag up by the neck only. Bags should not be clasped against the body. Do not attempt to carry too many bags at one

time. Do not throw or drop the bags. Do not support the bag from the bottom. Do not leave the waste unattended. Conduct spillage clean-up when the need arise.

MANUAL HANDLING OF SHARP CONTAINERS

No darting needles into the bin. Sealed when 3/4 full. Syringes with attached needles shall be discarded together. Do not shed needle. Do not press down the bin lids when closing. Shake the container gently before closing. Check if bin is labeled with date and site of origin. Keep out of reach of children. Intravascular guidewires, cannulae, blood taking sets, glass slides, glass dry vials & ampoules shall be discarded into the correct size containers.

Syringes/needles in yellow bag - Big Mistake…

Result in deadly consequences!!!

LABELLING

All bag and sharp containers shall be labeled for identification purpose.

WHY??

Should any problem arise, the waste can be easily traced.

LABELLINGLabels should have:

• Date waste first generated

• Name, Add & Contact no. of waste generator

• Marked with biohazard symbol and code SW404

Designated area for storage. Locked & attended at all time. Separated from general waste store. Minimum 2 days storage capacity. Accessible only by authorized person. Facilities for washing hands made available. Connected to sewerage system. PPE made available. Refrigerated storage required if stored for >24

hours. Free from vermin, droppings, etc. Odour control. Good housekeeping.

STORAGE OF CLINICAL WASTE

“Old mortuary house turn domestic waste store…. Temporarily utilised as

CW storage in 1996”

STORAGE OF CW- THEN

STORAGE OF CW-NOW

Landfill Autoclave (Steam

treatment) Irradiation Microwave Treatment Chemical Disinfection

• Incineration

CLINICAL WASTE DISPOSAL

Combustion of waste at high temperature with O2 to produce

inert ash, CO2, H2O and trace levels of pollutants.

WHAT IS INCINERATION

Because generation of waste increases daily. Scarcity of landfill sites. Sustain clean environment. Reduces pollution due to open burning. Ensures total destruction of pathogen & organic

material. Complies with DOE emission control standard.

NEED FOR INCINERATION

CW DISPOSAL-THEN

CW DISPOSAL - NOW
