BIOSAFETY LABORATORY

What is Biosafety laboratory?
A biosafety laboratory is a controlled lab environment with engineering systems, procedures, and protective equipment to prevent exposure to infectious agents.

 

Key Features of a Biosafety Laboratory

1. Containment Systems

• • Primary containment: Biosafety cabinets (BSC)
  • Secondary containment: Room design, airflow, sealed structure
    
    

2. Airflow Control

• • Negative pressure (air flows into the lab, not out)
  • Prevents contamination from escaping
    
    

3. Filtration

• • HEPA filters on supply and exhaust air
    
    

4. Access Control

• • Restricted entry (authorized personnel only)
  • Airlocks in higher-level labs
    
    

5. Decontamination Systems

• • Autoclaves (for sterilization)
  • Chemical disinfection systems
    
    

6. Personal Protective Equipment (PPE)

• • Gloves, lab coats, face shields
  • Advanced suits in BSL-4
    
    

 Common Applications

• Medical and clinical research
• Vaccine development
• Microbiology and virology studies
• Disease diagnostics
