Lab. Safety 2 Study Questions 1. What is the primary purpose of a biosafety cabinet (BSC)? To protect the laboratory worker and the environment from pathogens 3. When is eye protection required in the lab? Answer: When using chemicals, glassware, or heating sources, and when dust or fumes are present. Eye protection is vital to prevent injuries in various laboratory activities. 4. What are Risk Groups, and why is it important to classify pathogenic organisms into these groups in a clinical laboratory? 5. Describe two examples of work conducted in a BSL-3 clinical laboratory and explain why these activities require higher containment than typical BSL-2 work. 6. What types of personal protective equipment (PPE) are typically used in a BSL-2 laboratory, and under what circumstances might additional PPE be required? 7. Why is eye protection critical in laboratory environments, and what types of eye protection are typically used? 8. Describe the maintenance and inspection steps for personal protective equipment (PPE) in a laboratory, specifically for gloves. 9. What are bloodborne pathogens, and which pathogens pose the greatest risk to healthcare workers in this situation? 10. Describe the key components of an Exposure Control Plan that must be in place in your workplace according to OSHA’s Bloodborne Pathogens Standard. 11. What engineering and work practice controls can be used to prevent needlestick injuries in the future? 12. What role does the Laboratory Director or Safety Officer play in determining the necessity for enhanced biosafety practices? 13. Explain the differences between Risk Group 2 and Risk Group 3 pathogens, and give examples of each. 14. A chemical in your laboratory is labeled with the Corrosion hazard pictogram. What risks are associated with this chemical? What PPE should you wear when handling it? 15. Describe two examples of work practice controls that help reduce exposure to bloodborne pathogens. Bonus Questions: 1. Explain how a laboratory risk assessment influences the selection of safety practices and containment measures in a clinical laboratory. 2. Why is PPE considered the “last line of defense” in laboratory safety, and what other controls should be prioritized to ensure safety in a clinical laboratory? 3. How would you evaluate the effectiveness of the Exposure Control Plan in your workplace? Describe specific metrics or methods you would use to assess compliance and effectiveness. 4. An employee has experienced a needlestick injury while handling a blood sample from a patient known to be infected with HBV. Describe the immediate steps that should be taken by the employee following the injury, including both first aid measures and reporting procedures. 5. Discuss the potential risks associated with needlesticks and other sharps-related injuries in healthcare settings. What are some best practices for handling sharps to minimize these risks? 6. Why is personal protective equipment (PPE) considered the "last line of defense" in laboratory safety, and how does it differ from engineering controls?
