Study Notes
Microbiology Laboratory
- A microbiology lab studies microorganisms like bacteria, viruses, and fungi.
- Key tasks include culturing, identifying microbes, and testing treatments.
- Common tools include microscopes, autoclaves, and incubators.
- Microbiology labs are essential for diagnosis, research, and product safety (e.g., healthcare, food).
Laboratory Safety
-
General Conduct:
- Avoid distractions (e.g., horseplay).
- Follow all instructions (written and verbal).
- Work in pairs or groups.
- Conduct only assigned experiments.
-
Personal Protective Equipment (PPE):
- Wear lab coats to prevent contamination.
- Use gloves when handling microorganisms or contaminated surfaces.
- Change gloves frequently.
- Use eye protection (safety goggles or face shields).
- Wear masks or respirators if necessary.
-
Hand Hygiene:
- Wash hands thoroughly before and after lab work, especially after removing gloves.
-
Sterilization and Disinfection:
- Sterilize equipment and tools before and after use (e.g., autoclaves).
-
Aseptic Techniques:
- Use flame sterilization (Bunsen burners) and laminar flow hoods.
-
Containment Measures:
- Use biosafety cabinets (BSCs) for high-risk pathogens.
- Seal petri dishes/tubes securely.
-
Good Laboratory Practices:
- Label all cultures, media, and hazardous materials.
- No food or drinks in lab.
- Use mechanical pipetting devices; avoid mouth pipetting.
- Reduce aerosols by avoiding vigorous shaking.
-
Training and Protocols:
- All lab personnel should be trained on safe handling procedures.
- Regular safety drills and updated training.
- Follow specific biosafety level guidelines.
-
Emergency Procedures:
- Know the location of safety equipment (showers, eyewash, fire extinguishers).
- Handle spills/accidents involving microorganisms.
- Report accidents/exposures immediately.
-
Disposal:
- Dispose of microbial waste appropriately (e.g., biohazard bins).
- Use proper methods for autoclaving biohazardous waste.
-
Waste Management:
- Use leak-proof containers for sharps (needles).
- Autoclave biohazard waste before disposal.
- Label waste properly.
-
Post-Lab Behavior:
- Clean up equipment and workspace.
- Turn off equipment.
- Wash hands thoroughly.
-
Biosafety Levels:
- BSL-1: Basic safety (non-pathogenic strains).
- BSL-2: Moderate risk organisms (advanced PPE).
- BSL-3/4: High-risk organisms (strict containment and advanced protocols).
