HEALTHCARE WASTE MANAGEMENTStepping Towards Quality Improvement & Safety
“THE APOLLO WAY”
HEALTHCARE WASTE HAZARDS• Infectious & pathological• Sharp injuries• Hazardous chemicals• Radioactive• Cytotoxic & Genotoxic
DISEASE TRANSMISSION• Air borne• Direct contact / sharp injuries (through broken skin)• Diseases:
• Hepatitis-B• AIDS• Tetanus• Diseases of GI tract & respiratory system• Skin diseases & many more
WHO ARE AT RISK?
• Doctors • Nursing staff• Ward staff• Housekeepers• Patients & visitors• Community• Environment
HEALTHCARE WASTE MANAGEMENT
• Structure• Processes• Outcomes
POLICY• To outline the SoPs to manage various types of
wastes• To avoid nosocomial infections• To encourage safe working practices• To ensure environmental conservation
GOLDEN RULES• Segregation at the source
• No mixing
• No storage beyond 48 hours
• PPE & Universal precautions
WASTE CLASSIFICATION• Clinical waste• Sharps waste• Chemical waste• Pharmaceutical waste• Laboratory waste• Radio-active waste• Cytotoxic /genotoxic waste • Confidential waste• Food & domestic (general) waste

HEALTHCARE WASTE MANAGEMENT
Type of Waste
Non-infectious Waste (80-85%)
Infectious Waste (15-20%)
SEGREGATION• Responsibility of all staff.• At the source of generation itself.• Clear identification & sorting.• Display of segregation guidelines. • Color coding and labeling .

BLUE Glass items, needles, syringes, scalpels, blades, used and unused sharps
BLACK Radioactive and chemotherapy wastage
GREEN General waste, non-infected plastic materials & papers, disposables, cardboards, metal containers, office waste, food waste
SEGREGATION• Allow to fill the bag/bin up to 3/4th level.• Hub cutters for needles.• Other sharps: puncture proof auto-locked containers.
SEGREGATION
SEGREGATION
• Thumb Rule: Mutilate disposable and plastic items and empty the glass vials & bottles before throwing in waste bins.
• Proper segregation:• Facilitates further collection, handling, storage &
disposal of waste.• Minimizes the cost of handling and disposal of
waste.
COLLECTION• Scheduled collection by Housekeeping Staff.
• 2 hourly in ICUs• 4 hourly in wards/other clinical areas
• Thumb Rule: Tie on the top. Do not compress the bag. Lift the bag from the top. Do not support the bottom of the bag with the other hand.
• Regular washing & disinfection. Checklist for washing/disinfection.
• Use of PPE while collecting waste.
COLLECTION
LOCAL STORAGE• Temporary storage:
• Colour coded containers / big polythene bags• Labelling • Local collection points (closed dirty utility rooms)• Away from patient areas
• No mixing of infectious and non-infectious waste.• Thumb Rule: Waste from local storage must be
transported to central collection site within two hours of collection.
LOCAL STORAGE
TRANSPORTATION TO CENTRAL STORAGE SITE• From local storage areas to central storage area:
• Closed air-tight color-coded container trolleys• Scheduled time interval• Pre-defined waste route• Well demarcated dirty utility lift
• Thumb Rule: No crossing over with food trolleys or sterile areas.
TRANSPORTATION TO CENTRAL STORAGE SITE• Scheduling & separate routes for waste trolleys &
food trolleys.
• Regular washing & disinfection of container trolleys. Checklist for washing/disinfection.
• Use of PPE while transporting waste.
CENTRAL STORAGE AREA• Away from clinical areas, kitchen, stores & public routes.• Restricted entry.• Adequately lit & ventilated rooms with impervious floor.• Color-coded self-closing doors.• Facility of washing area.• Provision of First Aid Kit.• Availability of PPE.• Fire extinguishers.• Regular washing and disinfection. Checklist.
CENTRAL STORAGE AREA
TRANSPORTATION TO FINAL DISPOSAL SITE• Daily. • Outsourced to Government authorized CBWTF
(Common Biomedical Waste Treatment Facility).• In a closed cart/vehicle with smooth & impermeable
surfaces.• Thumb Rule: No waste should be kept stored in the
hospital beyond the period of 48 hours.
TRANSPORTATION TO FINAL DISPOSAL SITE
• Weighing of waste to monitor the waste volume/bed.
• PPE while handling the waste. Immunized personnel.
• Once a month, visit by Infection Control Coordinator to the disposal site.
• General/food waste – municipal vehicle.

prophylaxis.• Reporting to Emergency Department or Staff Clinic
at earliest.
ACCIDENTS & INCIDENTS• Prompt reporting to Quality/Infection Control Dept:
• Inappropriate segregation• Leakage & spillage• Damaged containers• Splashes & Sharp Injuries• Mixing of general waste with biomedical waste• Excessive accumulation
ACCIDENTS & INCIDENTS
• Retention of the item and identification of possible infection.
• Investigation and RCA• CAPA to prevent recurrences.
PERSONAL PROTECTION• Disposable gloves & heavy-duty gloves• Industrial apron / leg protectors• Face shields & protective glasses• Sturdy industrial boots• Helmets & strong industrial PPE in high risk areas.• Masks & respiratory protectors for protection
against toxic dust.• Standard PPE (approved by BARC) for protection
against radioactive wastes.
PERSONAL PROTECTION
PERSONAL PROTECTION• Protective equipment - cleaning & maintenance.• Periodic/surprise checking.• Hepatitis-B and tetanus vaccination.• Washing facilities at storage & disposal areas.• Insistence on hand washing practices.
STAFF SAFETY• Pre-employment & annual health check• Vaccination & online monitoring of immune status • Training on occupational safety• Display of SoPs at all working areas• Provision of required PPE and periodic inspection• Spillage Kits, Mercury Kits• HAZMAT Kits• First Aid Kits• Fire Fighting Equipment
