Disposal of Waste from Injection Room - SPM

Waste Generated in an Injection Room

BMW Management Rules 2016 - Colour Coding System

1. Yellow Bag (Incineration)

• Human anatomical waste, soiled cotton, gauze, bandages contaminated with blood/body fluids
• Discarded medicines, chemical waste
• Method of disposal: Incineration

2. Red Bag (Autoclaving/Microwaving)

• Contaminated recyclable plastic waste - used syringes (after needle removal/destruction), IV tubing, catheters
• Method: Autoclave or microwave → then shredded → sent to recycler
• From injection room: Syringe bodies go here

3. White/Translucent Puncture-Proof Container (Sharps)

• Used needles, blades, broken glass ampoules, vials, lancets
• Must be placed in a puncture-proof, leak-proof sharps container
• Method: Autoclaving + shredding/mutilation, OR encapsulation, OR plasma pyrolysis

4. Blue/White Translucent Box - Glass Container

• Broken or discarded glass (non-contaminated)
• Method: Disinfection + disposal to recycler

Step-by-Step Disposal Process from Injection Room

Step 1 - At the Point of Use (Injection Room itself)

1. Needle destruction: Immediately after injection, use a needle cutter/hub cutter or needle destroyer device to cut/destroy the needle
2. The cut needle falls into an integral sharps container within the device
3. The syringe body (now needle-free) is placed in the Red bag
4. Used cotton/swabs → Yellow bag
5. Glass ampoules/vials → White puncture-proof sharps container

Step 2 - Segregation at Source (CRITICAL principle)

• Never recap needles (two-hand technique is forbidden; if needed, use one-hand scoop method)
• Segregation must happen at the point of generation - not later
• Bins/bags should be labelled with the biohazard symbol
• Bags filled only up to 3/4 capacity

Step 3 - Collection and Storage

• Collected by healthcare workers wearing PPE (gloves, masks)
• Moved to BMW storage area within the hospital
• Storage time: Not more than 48 hours (within healthcare facility)

Step 4 - Transportation

• In dedicated closed, leak-proof containers/trolleys
• Labelled with biohazard symbol
• Transportation log maintained

Step 5 - Final Disposal (by CBWTF - Common Bio-medical Waste Treatment Facility)

• Authorized CBWTF operators collect and treat/dispose
• Autoclaving, incineration, or other approved methods

Key Points for Exam (Park's SPM)

3R Principle Applied

• Reduce: Minimize waste generation; use unit-dose packaging
• Reuse: NOT applicable for injection room waste (single-use items only)
• Recycle: Plastic syringe bodies (after decontamination via Red bag route)

Important Distinctions

• Used syringe needle - White puncture-proof sharps box
• Syringe body (plastic) - Red bag
• Soiled cotton - Yellow bag
• Empty ampoule (glass, contaminated) - White puncture-proof sharps box
• Gloves - Yellow bag (if contaminated with blood/body fluids)

Disposal of Urinary Catheter - SPM / BMW Management

What a Urinary Catheter Set Produces

Disposal as per BMW Rules 2016 - Colour Code

RED BAG - Contaminated Recyclable Plastic Waste

• These are non-sharp, contaminated plastic/rubber items
• Red bag = contaminated recyclable plastic waste
• Treatment: Autoclaving or microwaving → then shredded/mutilated → sent to authorized recycler
• They must NOT go to yellow bag (that is for incinerable waste)

YELLOW BAG - Soiled/Infected Non-Plastic Waste

• Used gauze, cotton, swabs used during catheter insertion
• Lignocaine-soaked packing material
• Treatment: Incineration at CBWTF

Urine (Liquid Waste)

• Urine from the catheter bag: Can be disposed into the drain/sewage after it has been passed through a closed drainage system
• If the patient has a known infectious condition (e.g., multidrug-resistant organisms), the urine should be chemically disinfected (e.g., with 1% hypochlorite solution) before drain disposal
• Governed by liquid waste rules under BMW 2016

BLUE/WHITE BOX (if applicable)

• If a metal introducer or trocar was used - goes into the white puncture-proof sharps container
• Broken glass ampoule of lignocaine → white sharps container

Step-by-Step Disposal Protocol

Step 1: At point of removal
        ↓
   Drain urine into designated drain/flush with disinfectant
        ↓
Step 2: Catheter + bag + tubing
        ↓
   Place in RED BAG (contaminated plastic)
        ↓
Step 3: Gloves + gauze/cotton
        ↓
   Place in YELLOW BAG
        ↓
Step 4: Any sharps used
        ↓
   WHITE puncture-proof sharps container
        ↓
Step 5: Red bag sent to CBWTF → Autoclave → Shred → Recycle
        Yellow bag sent to CBWTF → Incineration

Key Exam Points

Common Exam Trap

"A used urinary catheter should go in the yellow bag" - WRONG

Memory Aid

"Red = Recyclable plastic (contaminated)" "Yellow = You burn it (anatomical + soiled non-plastic)" "White = Sharp things (needles, blades, glass)"

Biomedical Waste - Definition, Sources, and Key Points

Definition

"Bio-medical waste means any waste which is generated during the diagnosis, treatment or immunization of human beings or animals, or in research activities pertaining thereto, or in the production or testing of biologicals."

• 75 to 90% of health-care waste is non-risk / general waste - comparable to domestic waste (from administrative and housekeeping functions)
• The remaining 10-25% is hazardous and creates a variety of health risks

Sources of Biomedical Waste

1. Government hospitals
2. Private hospitals
3. Nursing homes
4. Physician's offices/clinics
5. Dentist's offices/clinics
6. Dispensaries
7. Primary Health Centres (PHCs)
8. Medical research and training establishments
9. Mortuaries
10. Blood banks and collection centres
11. Animal houses
12. Slaughter houses
13. Laboratories
14. Research organizations
15. Vaccinating centres
16. Bio-technology institutions/production units

All these are covered under the BMW Rules.

Composition of Hospital Waste in India

Waste Generation Estimates (WHO - Developing Countries)

• In Bangalore survey: waste generated = 1/2 to 4 kg/bed/day in Government hospitals; 1/2 to 2 kg/bed/day in private hospitals; 1/2 to 1 kg/bed/day in nursing homes

Health Hazards of Biomedical Waste

Groups at Risk

• Doctors, nurses, healthcare auxiliaries, hospital maintenance staff
• Patients in healthcare establishments
• Visitors to healthcare establishments
• Workers in support services (laundries, waste handling, transportation)
• Workers in waste disposal facilities (landfills, incinerators) including scavengers

Types of Hazards

• Pathogens enter via puncture/cut in skin, mucous membranes, inhalation or ingestion
• Strong evidence of HIV, Hepatitis B and C transmission via healthcare waste
• Antibiotic-resistant bacteria add further hazard

• Toxic, genotoxic, corrosive, flammable, reactive chemicals
• Cytotoxic drug residues pose carcinogenic/mutagenic risk

• Cytotoxic agents, radioactive materials
• Risk of mutagenesis and carcinogenesis to exposed workers

• Radioisotopes used in diagnosis/therapy
• Risk of radiation injury, contamination

BMW Management Rules in India - Key Points

Colour-Coded Segregation (BMW Rules 2016 - Schedule 1)

Key Principles of BMW Management (Memory Aid)

SWERC

• Segregation at source
• Waste minimization
• Encapsulation/treatment before final disposal
• Recycling where safe
• CBWTF for final processing

• Park's Textbook of Preventive and Social Medicine, pp. 891-895

BMW Rules - Enforcement & Penalties in India

Legal Framework

Enforcement Authorities

1. Central Level

2. State Level

3. Special Case

• For healthcare establishments under the Ministry of Defence (Armed Forces hospitals etc.) - the prescribed authority is the Director General, Armed Forces Medical Services

Authorisation System

• Every healthcare facility (HCF) generating BMW must obtain authorisation from the SPCB/PCC
• Authorisation is issued in Form I under the Rules
• Facilities must renew authorisation periodically
• Any change in activity → fresh application for modification of authorisation required
• Facilities must submit annual reports to the prescribed authority

Duties of Occupier (Rule 4) - Basis for Enforcement Action

1. Segregate BMW at the point of generation as per colour-coded categories
2. Store BMW in specified containers/bags with biohazard symbol
3. Ensure no secondary handling or pilferage
4. Pre-treat liquid waste before disposal
5. Ensure transportation only to authorised CBWTF
6. Maintain records of BMW generated, treated, and disposed
7. Report accidents to the prescribed authority
8. Train all staff handling BMW at the time of induction and at least once a year
9. Establish a Biomedical Waste Management Committee
10. Display BMW management protocol in the facility

Liability of Occupier/Operator (Rule 18)

"The occupier or operator of a CBWTF shall be liable for all damages caused to the environment or the public due to improper handling of bio-medical wastes."

• Liable under Section 5 (power to give directions) and Section 15 (penalties) of the EPA
• Liability is strict - it applies to both the occupier (HCF) and the operator (CBWTF)

Penalties Under Environment (Protection) Act, 1986

Section 15 - Main Penalty Provisions

Original EPA 1986 (pre-amendment):

After Jan Vishwas Act, 2023 Amendment (Civil Penalties - decriminalised):

The Jan Vishwas Act 2023 decriminalised first-instance violations (removed imprisonment for initial violation) and replaced with civil monetary penalties. Imprisonment now applies only for non-payment of penalty.

Section 16 - Offences by Companies

• Where a company violates BMW Rules, every person in charge of the company at the time of violation is personally liable along with the company
• This means the Medical Superintendent, Hospital Director, or CMD can be prosecuted personally

Enforcement Powers of Prescribed Authority

1. Inspect healthcare facilities and CBWTF at any time
2. Issue directions under Section 5 of EPA (closure, prohibition of activity, stoppage of supply of utilities)
3. Cancel or suspend authorisation for non-compliance
4. Conduct third-party audits of CBWTF
5. File complaints for prosecution under Section 15
6. Impose penalties and direct payment of environmental damages

Advisory Committee (Rule 11)

• Every State Government must constitute an Advisory Committee
• Chaired by the State Health Secretary
• Includes representatives from:
  • Health Department
  • Environment Department
  • Urban Development Department
  • Animal Husbandry and Veterinary Sciences Department
• Function: Oversee implementation and advise improvements

Key Exam Points

Important Practical Enforcement Issues (Current Reality)

• India has ~3,93,000 healthcare facilities; only ~1,56,000 are authorised under BMW Rules (as of 2024 CPCB data)
• Smaller clinics, diagnostic labs, and first-aid rooms remain largely non-compliant
• In 2024, CPCB introduced revised guidelines for CBWTFs to improve treatment capacity and compliance monitoring
• Studies show lack of awareness and training is the primary reason for poor compliance - not just absence of enforcement
