PREVENTION EXAM QUESTIONS WITH CORRECT
ANSWERS |2026 LATEST UPLOAD WITH COMPLETE
SOLUTION
1. What is the primary purpose of filtration systems in biosafety cabinets?
Provide illumination for the workspace
Trap airborne particles and contaminants
Regulate temperature inside the cabinet
Control humidity levels
2. What is the primary risk associated with aerosol generation in laboratory
settings?
Increased risk of exposure to airborne pathogens
Reduced need for biosafety cabinets
Increased contamination of laboratory surfaces
Decreased effectiveness of personal protective equipment
3. What is the proper disposal method for equipment that has been in
contact with live cultures in a BSL-3 laboratory?
Thrown in regular trash after rinsing.
Washed with soap and water.
Discarded in a biohazard bag within the BSC and autoclaved.
Reused after sterilization with alcohol.
4. What is the primary purpose of the inward airflow in a Class II Type A2
,biosafety cabinet?
Ensuring operator safety by preventing escape of hazardous
agents
Facilitating quick removal of contaminated air from the cabinet
, Protecting the environment from contamination
Maintaining sterile conditions for sensitive experiments
5. What is the first step in maintaining a biosafety cabinet in a BSL-3
laboratory?
Replace the filters
Turn off the biosafety cabinet
Clean the biosafety cabinet
Calibrate the airflow
6. If a researcher accidentally spills live cultures on a piece of equipment,
what steps should they take to ensure safety and compliance with BSL-3
protocols?
The researcher should immediately contain the spill, disinfect the
area, and then dispose of the equipment in a biohazard bag for
autoclaving.
The researcher should wipe the equipment with a paper towel and
reuse it.
The researcher should rinse the equipment with water and store it.
The researcher should leave the spill and report it later.
7. Describe how personal protective equipment contributes to safety in a
BSL-3 laboratory.
PPE is primarily for preventing equipment contamination.
PPE is used to enhance the aesthetic appearance of laboratory
workers.
PPE is only necessary during the decontamination process.
PPE protects laboratory personnel from exposure to hazardous
biological agents.
, 8. What is the primary purpose of biosafety cabinets in a laboratory?
To store chemicals safely.
To analyze biological samples.
To provide a controlled environment for handling hazardous
materials.
To maintain temperature control.
9. If a BSL-3 laboratory fails to leave centrifuge lids and rotors open after use,
what potential risks could arise?
Increased risk of contamination and exposure to hazardous
materials.
No significant risks are associated.
Enhanced sterility of the laboratory environment.
Improved efficiency in sample processing.
10. Describe the role of a biojar in maintaining safety protocols within a BSL-3
laboratory.
A biojar helps in the classification of pathogens.
A biojar is used to store hazardous chemicals safely.
A biojar is primarily for the storage of personal protective
equipment.
A biojar serves as a containment device that prevents the escape
of contaminated materials, thereby protecting the laboratory
environment and personnel.
11. In a BSL-3 laboratory, if sterility testing reveals the presence of viable
microorganisms in a sample, what immediate action should be taken?
Increase the air pressure in the laboratory.
