Which method requires proper ventilation due to toxic vapors?

• A. Steam sterilization
• B. Dry heat sterilization
• C. Chemical vapor sterilization
• D. Ultraviolet sterilization

Answer: (C)

When a sterilization method uses volatile chemicals, it can release toxic vapors that you don’t want lingering in the room. The chemical vapor sterilization method uses a chemical sterilant that vaporizes when heated, producing hazardous fumes. To protect people and ensure safe operation, the space must have proper ventilation or an exhaust/scavenging system to remove those vapors. Steam sterilization relies on steam alone, with no hazardous vapors generated in the process. Dry heat uses hot air, not chemicals. Ultraviolet sterilization uses UV light to kill microbes, so there are no toxic vapors produced by the process itself. Because of the potential for toxic vapors, ventilation is essential specifically for the chemical vapor method.
