Which practice best mitigates exposure to anesthetic vapors during surgery?

• A. Use a closed system with no ventilation
• B. Rely solely on personal protective equipment
• C. Store solvents near heat sources
• D. Ensure proper room ventilation and scavenging with appropriate storage

Answer: (D)

Controlling exposure to anesthetic vapors hinges on removing waste gases from the operating room rather than relying on protective gear alone. A functioning scavenging system captures waste anesthetic gases at the source, and proper room ventilation dilutes and expels any vapors that escape the anesthesia circuit, keeping ambient levels low for everyone in the room. While personal protective equipment adds a layer of protection, it cannot eliminate vapor from the environment, so it’s not sufficient by itself. Storing solvents near heat sources is unsafe and can increase vapor generation and fire risk, and a closed system with no ventilation would actually trap gases instead of removing them. The combination of effective ventilation and scavenging—along with safe storage practices—best minimizes exposure to anesthetic vapors during surgery.
