Study Notes
Learning Objectives
- Understanding the importance of universal precautions in laboratory safety.
- Recognizing appropriate personal protective equipment (PPE) for lab work.
- Importance of hand hygiene in preventing infections.
Laboratory Safety Overview
- Laboratory safety rules are vital for all clinical laboratory students.
- Adhering to safety protocols protects individuals and prevents injuries.
Importance of Laboratory Safety
- Laboratory safety minimizes risks of injury and infection.
- Established safety rules and symbols guide safe practices.
Sterilization and Disinfection
- Sterilization: Process that kills all microbial life, including bacterial spores; can be achieved through physical or chemical means.
- Disinfection: Destroys pathogenic organisms but not all microbes or spores.
Methods of Sterilization
- Physical Methods:
- Heat:
- Moist Heat (e.g., Autoclave) most effective at 121°C, 15 PSI for 15 minutes.
- Boiling at 100°C for 15 minutes kills vegetative bacteria.
- Dry Heat Oven: Uses Bacillus subtilis variation niger as a biological indicator.
- Non-ionizing Radiation: Effective for non-penetrative surface exposure.
- Heat:
- Chemical Methods:
- Disinfectants: Phenol, QUATS, chlorine, and 2% glutaraldehyde destroy microbes on inanimate surfaces.
- Antiseptics: Microbiostatic agents like alcohol and iodine tincture for living tissues.
Biological Indicators
- Autoclave indicator: Bacillus stearothermophilus or Clostridium PA3679.
- Ionizing radiation indicator: Bacillus pumilus.
- Ethylene oxide indicator: Bacillus subtilis variation globijii.
Laboratory Safety Symbols and Equipment
- Use proper symbols to identify hazards and safety equipment in the laboratory, including biological safety cabinets.
Environmental Control Practices
- Ensure effective procedures for routine cleaning and disinfection of environmental surfaces.
- Handle soiled linen without contaminating skin or transferring microorganisms.
Occupational Health and Bloodborne Pathogens
- Avoid recapping needles; utilize safety devices for needle manipulation to prevent injuries.
Murphy's Law and Disaster Management
- Murphy's Law highlights that things can go wrong despite careful planning, emphasizing the need for disaster preparedness.
- Implement fail-safes to mitigate risks effectively.
Fire Safety
- Understanding the classes of fires and selecting the appropriate type of extinguisher for each class.
Hand Hygiene Protocol
- Wash hands when visibly soiled or use hand rub otherwise.
- Follow a thorough handwashing procedure lasting 40-60 seconds to ensure effective hygiene.
