Guideline Instructions

Safe Work Practices

  1. Handling Specimen

    • Always wear gloves and laboratory coats when handling specimens.

    • Ensure to bandage open cuts before gloving.

    • Wash hands after glove removal and before exiting the laboratory.

    • Specimen Transport: Use leak-proof containers and reject contaminated specimens.

    • Needles and Syringes: Never bend or recap needles; use puncture-proof containers for disposal.

  2. Handling Chemicals

    • Wear appropriate PPE while handling hazardous chemicals.

    • Label all reagents with chemical names and hazard warnings based on Material Safety Data Sheets (MSDS).

    • Store hazardous materials below eye level and avoid mouth pipetting.

Housekeeping and Miscellaneous Safe Practices

  • Designate areas for clean/contaminated work.

  • Clean a disinfect surfaces after spills and shift ends.

  • Prohibit food and drinks in the lab.

  • Regularly dispose of contaminated materials in marked bags.

Decontamination Protocol

  1. Routine Decontamination

    • Clean work surfaces thrice daily with disinfectants.

  2. Decontamination of Equipment

    • Follow surface cleaning procedures as per the supervisor's guidance.

  3. Decontaminating Spills

    • Major spills require appropriate PPE for cleaning, use sodium hypochlorite disinfectant, and report incidents.

    • Minor spills require similar treatment but with less evacuation necessity.

Waste Disposal

  • Proper management of biohazardous waste to limit health risks to workers.

  1. Segregation

    • Specific colors for different waste types: Yellow for microbiological waste, Red for sharps, and Black for general waste.

  2. Transport

    • Ensure bags are securely tied to prevent spillage when transported.

Laboratory Areas

  • Access is restricted; visitors require supervisor approval.

  • Use hazard labels to communicate risk levels within the facility.

Laboratory Accidents Management

  1. Needlestick Injuries

    • Immediate washing and notification of supervisors required.

  2. Eye Wash Station

    • Located on the first floor for quick access in case of chemical exposure.

Fire Safety Procedures

  • Be vigilant of the potential for fires in labs due to flammable solvents.

  1. Prevention Measures

    • Keep work areas organized, store chemicals safely, and participate in fire safety training.

  2. Emergency Procedures

    • Know how to use fire extinguishers and what equipment is available in emergencies.

Classification of Fire and Extinguishing Agents

  • Classify fires as A (Ordinary combustibles), B (Flammable liquids), and C (Electrical fires); use appropriate extinguishing agents based on the class.

Material Safety Data Sheets (MSDS)

  • Detailed sections on handling sodium hypochlorite, sulfuric acid, and hydrochloric acid covering identification, physical properties, hazards, and first aid measures.

  • Emphasis on thorough understanding of chemical properties, emergency protocols, and ecological impacts.
