What is the primary purpose of Body Substance Isolation (BSI)?

• A. Prevent exposure to biological, chemical, or physical hazards
• B. Isolate suspects from bystanders
• C. Ensure proper cleanup
• D. Protect responders from exposure to hazards

Answer: (A)

Body Substance Isolation is about creating protective barriers to prevent responders from coming into contact with potentially infectious or hazardous body substances. The best choice expresses this preventive function clearly: it focuses on avoiding exposure to biological, chemical, or physical hazards by using PPE and barrier techniques. This approach means treating all body fluids as potentially infectious and acting to minimize contact—gloves, gowns, masks, eye protection, and proper decontamination are part of staying safe on the scene. The other options describe related tasks that aren’t the primary aim of BSI—scene control, cleanup procedures, or separate decontamination duties—while BSI’s core purpose is to protect the responder through barrier precautions.
