Q: All the gases given below are used for gaseous sterilization except-
  • A. Formaldehyde
  • B. Ethylene Oxide
  • C. Nitrous oxide
  • D. Beta-Propiolactone
Correct Answer: Option C - Gaseous sterilization– Gaseous sterilization is the method where the object is exposed to gas in a closed, heated and pressurized chamber. Types of gases used for sterilization – i.e., ethylene oxide, formaldehyde gas & Beta propiolactone (BPL). So nitrous oxide is not used for gaseous sterilization.
