LAB-QM-IC-001 — Infection Prevention, Hand Hygiene, and Healthcare Waste Management Policy

1.0 Purpose

To establish a unified operational infection control policy for the Tarangnan Community Hospital (TCH) Clinical Laboratory, governing standard precautions, hand hygiene, personal protective equipment (PPE), bench cleaning, environmental surface disinfection, healthcare waste segregation, and biological spill containment. This policy prevents the transmission of infectious agents to laboratory personnel, patients, hospital staff, and the surrounding community in accordance with DOH licensing regulations and national healthcare waste guidelines.

2.0 Scope

This policy applies to all personnel performing diagnostic testing, phlebotomy, specimen handling, cleaning, and waste management within the TCH Clinical Laboratory and affiliated patient-care collection points. It covers routine handwashing, PPE compliance, daily and post-spill surface decontamination, point-of-generation healthcare waste segregation, and coordination with the hospital Waste Management Officer. Technical safety controls, chemical hazards, and fire safety remain governed by Laboratory Safety Policy.

3.0 Definitions

• Standard Precautions — the primary infection control practice treating all human blood, body fluids, and clinical specimens as potentially infectious regardless of source or diagnosis.
• Hand Hygiene — the general practice of decontaminating hands using liquid antiseptic soap and running water (40–60 seconds) or an alcohol-based hand rub (ABHR) (20–30 seconds).
• Decontamination — the physical and chemical procedure eliminating infectious pathogens from work surfaces, instruments, or blood collection trays using an approved hospital disinfectant.
• Infectious (Biohazard) Waste — healthcare waste saturated, caked, or contaminated with blood or body fluids, designated for yellow-bag packaging and secure disposal.
• General Waste — uncontaminated packaging, office trash, paper products, and non-biohazard materials designated for black-bag disposal.
• Sharps Waste — all puncture-capable items (needles, lancets, glass slides, broken tubes, capillary tubes) requiring immediate disposal into rigid, puncture-proof sharps boxes.

• Decontaminate testing benches before and after each duty shift, segregate generated waste immediately at point-of-use, and manage biological spills promptly.

4.6 Laboratory Aides

• Carry out designated routine cleaning and surface decontamination of laboratory floors, sinks, non-analytical surfaces, and transport trays.
• Seal, weigh, label, and transfer bagged healthcare waste to the hospital temporary holding area using appropriate heavy-duty protective equipment; do not handle analytical testing.

5.0 Policy / Procedure

5.1 Standard Precautions and Hand Hygiene Protocol

• Standard Precautions Mandate: All clinical specimens (blood, urine, stool, body fluids) handled in the TCH laboratory shall be managed under Standard Precautions.
• Hand Hygiene Occasions: Hands shall be decontaminated without exception: - Before and after every patient contact (phlebotomy or capillary collection); - Immediately before donning gloves and immediately after removing gloves; - Promptly after accidental contact with blood, body fluids, or contaminated labware; - After completing analytical batch testing or operating equipment; - Before leaving the laboratory work area and prior to eating or drinking.
• Cleaning Method: - Soap and Water: Mandatory whenever hands are visibly soiled, contaminated with blood, or after restroom use. Rub all surfaces with soap for at least 40 to 60 seconds, rinse thoroughly under running water, and dry with single-use paper towels. - Alcohol-Based Hand Rub (ABHR): Permissible when hands are not visibly soiled. Rub 3 to 5 mL of 70% ethyl/isopropyl alcohol over all hand surfaces for 20 to 30 seconds until completely dry.
• Gloves Rule: Gloves do not replace hand hygiene. Hands shall be washed or sanitized immediately upon glove removal.

5.2 Personal Protective Equipment (PPE)

• Required PPE Ensemble: Personnel shall wear appropriate PPE calibrated to the specific procedural risk: - Routine Bench Testing: Buttoned laboratory gown/coat and disposable nitrile or latex gloves; - Specimen Processing & Splashing Hazards: Laboratory gown, gloves, surgical mask, and protective goggles or full-face shield (mandatory during sample uncapping, vortexing, and pouring); - Waste Handling & Floor Cleaning: Heavy-duty utility gloves, rubber apron, and closed non-slip protective shoes.
• PPE Restrictions: Contaminated laboratory gowns and gloves shall never be worn outside the laboratory work area (e.g., in administrative offices, staff pantries, or public corridors).

5.3 Surface Cleaning and Environmental Decontamination

• Routine Cleaning Schedule: - Workbenches & Countertops: Decontaminated at the start and end of each shift, and immediately following any spill; - Centrifuges & Rotors: Cleaned and wiped with disinfectant weekly and after tube breakage; - Phlebotomy Trays & Racks: Cleaned at the end of each duty shift; - Sinks & Utility Areas: Cleaned daily by Laboratory Aides.
• Approved Disinfectants: - Routine Surface Disinfection: Freshly prepared 1:10 household bleach solution (0.5% sodium hypochlorite) or an equivalent hospital-approved quaternary ammonium disinfectant; - Contact Time: Maintain surface wetness for at least 10 minutes (or 20 minutes for high-protein organic matter) before wiping dry; - Instrument Touchscreens: Cleaned with 70% isopropyl alcohol to protect delicate optical components.
• Logging: Daily bench and floor decontamination shall be recorded on F-QM-IC-001-A-V0.

5.4 Healthcare Waste Segregation and Disposal

In compliance with the DOH Healthcare Waste Management Manual (4th Edition) and Republic Act No. 6969, waste must be segregated at the exact point of generation:

• Pathologic Waste Handling: Body tissues and fluid specimens shall be autoclaved or treated before chemical disinfection and transferred in sealed yellow containers.
• Waste Transport: Sealed bags and locked sharps boxes shall be transferred daily to the hospital central waste holding area by trained Laboratory Aides using dedicated transport carts.
• Disposal Contract: The hospital administration shall maintain a valid Memorandum of Agreement (MOA) and transport permits with a DENR/DOH-accredited hazardous waste treatment and disposal facility.

5.5 Biological Spill Response and Exposure Reporting

• Immediate Containment: In the event of a blood or specimen spill: - Alert personnel in the immediate vicinity and don complete PPE (gown, gloves, mask, eye protection); - Cover the spill completely with absorbent paper towels to prevent liquid spread; - Gently pour 1:10 freshly prepared bleach solution around the perimeter, working toward the center; - Allow 20 minutes contact time; - Wipe up waste using forceps or disposable dustpans, discard into a yellow biohazard bag, and repeat surface wiping.
• Centrifuge Breakage: If a blood tube breaks inside a running centrifuge, turn off the unit immediately and keep the lid closed for at least 30 minutes to allow aerosols to settle. Don heavy utility gloves, use mechanical forceps to remove glass fragments into a sharps container, and thoroughly disinfect the bowl and buckets with 1:10 bleach.
• Incident Reporting: All biological spills exceeding 50 mL or involving broken glass shall be logged in the Occurrence Log (Occurrence Management Policy). Accidental needlesticks or mucosal splashes require immediate medical referral and occupational exposure logging per Recruitment Qualification and Appointment Policy.

5.6 Staff Training, Competency, and Audits

• Training & Competency: All incoming personnel must complete infection control orientation covering hand hygiene, PPE donning/doffing, and waste segregation before independent duty. Annual competency reassessment is mandatory.
• Quality Audits: The Chief MT / LQM and Safety Officer shall conduct monthly infection control audits using F-QM-IC-001-A-V0. Nonconformances shall trigger immediate corrective action and discussion during section meetings.

6.0 Records

All completed cleaning logs, waste disposal manifests, and infection control audit records shall be filed in the laboratory safety folder and retained in accordance with Laboratory Retention Schedule Policy.
