Rationale: Chemical Sterilization

Sterilization is the process in which all types of microorganisms such as bacteria, viruses, fungi, and spores are completely destroyed.

Chemical sterilization is primarily used for items that cannot withstand heat (heat-sensitive items).

Endoscopes, cables, and delicate instruments are commonly sterilized using chemicals such as glutaraldehyde, ethylene oxide, or hydrogen peroxide.

These items are at risk of damage if subjected to high temperatures; therefore, the chemical method is considered suitable for them.

However, gauze is a heat-resistant material.

Gauze is commonly sterilized using autoclaving (steam sterilization) or dry heat.

Gauze is not sterilized with chemicals because chemical residues can remain, which may cause irritation or infection in the wound.
