Biosafety Training Latest Update with Verified Answers

Biosafety Training Latest Update with Verified Answers **Hierarchy of Controls** **Most Effective to Least Effective:** Elimination Substitution Engineering Controls Administrative Controls Personal Protective Equipment **Explanation:** The hierarchy of controls ranks methods for reducing or eliminating exposure to hazards, starting with the most effective (elimination and substitution) and ending with the least effective (personal protective equipment). **Biological Agents** **Examples:** bacteria, viruses, fungi, rickettsia **Explanation:** Biological agents include a range of microorganisms such as bacteria, viruses, fungi, and rickettsia, each with unique characteristics and potential health risks. **Biologic Agents' Routes of Exposure** **Routes:** ingestion, inhalation, mucous membrane exposure, inoculation **Explanation:** Biological agents can enter the body through different routes, including ingestion, inhalation, exposure to mucous membranes, and inoculation through breaks in the skin. **Biosafety Levels** **High Risk to Low Risk:** BSL-4 BSL-3 BSL-2 BSL-1 **Explanation:** Biosafety Levels (BSL) categorize laboratories based on the pathogens handled, ranging from BSL-4 (highest containment for dangerous pathogens) to BSL-1 (basic containment for agents unlikely to cause disease in healthy individuals). **Risk Group 1** **Characteristics:** Agents not associated with disease in healthy adult humans **Explanation:** Risk Group 1 pathogens do not cause disease in healthy individuals and pose minimal risk under standard laboratory conditions. **Risk Group 2** **Characteristics:** Agents associated with human disease that is rarely serious and for which preventative or therapeutic interventions are often available **Explanation:** Risk Group 2 pathogens can cause disease in humans, but the diseases are generally mild or treatable, posing moderate risk in laboratory
