Safety guidelines in a microbiology laboratory. Universal precaurions

Safety guidelines in microbiology laboratories are required to protect personnel and the environment and to prevent the spread of infection. The following are safety guidelines to be followed in the microbiology laboratories.

1. Personal protective equipment (PPE): Wear proper PPE to protect eyes, skin and cloth from microorganisms. PPE includes laboratory coats, gloves, and safety goggles or face shields.

2. Hand hygiene: Wash hands thoroughly before entering the laboratory, after handling microorganisms and before leaving the microbiology laboratory. Use proper soap and water or hand sanitisers to prevent the spread of microorganisms.

3. Laboratory Design and Layout: The design of the laboratory should have a proper ventilation system. I prevent the accumulation of air-borne contamination inside the laboratory. Its design should prevent cross-contamination.

4. Work area preparation: Disinfect work area surfaces and equipment before and after use. This prevents contamination and the spread of infection.

5. Labeling and storage: Label all containers properly with the name of the microorganism, date and person working. Store cultures, samples, and reagents at the proper temperature.

6. Aseptic techniques: Use aseptic techniques to handle microorganisms and prevent contamination.

7. Handling biohazardous materials: Infectious materials are considered biohazardous materials. Proper biological safety cabinets or fume hoods are used if working with aerosol-producing procedures.

8. Disposal of materials: Contaminated materials such as used cultures, pipettes, gloves etc. are biohazards. Dispose of them observing laboratory rules and regulations.

9. Emergency Procedures: Be familiar with emergency procedures, emergency exists, eyewash solutions, safety showers, fire extinguishers etc.

10. Training and education: Ensure training of all personnel on laboratory safety.

11. Personal behaviour: Avoid eating, drinking, applying cosmetics and touching faces in the laboratory. This prevents accidental ingestion or exposure to pathogens.

12. Reporting incidents: Report accidents or exposure to a supervisor or any responsible person. This helps to take quick action and medical attention.
