Study Notes
Purpose of Biosafety
- Primary aim is to protect laboratory personnel, the environment, and public health from exposure to hazardous biological agents.
BSL-1 Laboratory Requirements
- Requires minimal containment; typically does not require specific building design.
- No special ventilation systems are necessary.
- Work with low-risk agents that do not cause disease in healthy adults.
Common Requirement for BSL-1 and BSL-2
- Both levels require proper handwashing facilities available in the laboratory.
- Access to personnel protective equipment (PPE) is essential.
Key Difference between BSL-1 and BSL-2
- BSL-2 involves working with agents that pose moderate hazards to personnel and the environment, requiring additional safety precautions such as more stringent access controls and biosafety cabinets.
Integrated Pest Management in BSL-1
- Intended to minimize pest access to the laboratory which could compromise research or introduce contamination.
Key Requirement for BSL-1 and BSL-2
- Both levels mandate the availability and proper use of personal protective equipment (PPE) to protect against exposure to biological hazards.
Safety Level for High-Risk Agents
- BSL-4 is necessary for work with agents that cause high-risk aerosol-transmitted infections and potentially life-threatening diseases without available vaccines or effective treatments.
Waste Materials Truth Statement
- Incorrectly assumed that all laboratory waste can be treated as regular waste without specific handling and disposal requirements.
Recommended Safety Measures for Splatters or Aerosols
- Use of biosafety cabinets or other containment devices when handling infectious materials that could generate splashes or aerosols.
BSL Level for Serious or Potentially Lethal Diseases
- BSL-3 is appropriate for clinical, diagnostic, teaching, research, or production facilities dealing with agents that can cause serious disease via inhalation.
Decontamination Methods for Infectious Waste
- Common methods include autoclaving, incineration, or using chemical disinfectants specifically designed for biological waste.
