What is applied to remove harmful contaminants during the decontamination process?

• A. Heat only
• B. Physical abrasion
• C. Chemical agents
• D. Ultrasound

Answer: (C)

In the decontamination process, the primary goal is to remove harmful contaminants, which can include pathogens, organic matter, and other potential hazards. Chemical agents are specifically formulated to disinfect and sanitize surfaces and instruments, effectively breaking down contaminants and eliminating microorganisms. These agents can come in various forms, including liquids, sprays, or wipes, and are designed to work in conjunction with appropriate contact times and concentrations to ensure efficacy.

While heat can also be a part of the decontamination process—such as in autoclaving—heat alone is not sufficient for all types of contaminants. Physical abrasion can help in removing some debris but may not be effective against all microorganisms. Ultrasound can assist in cleaning, particularly in hard-to-reach areas, but it is typically part of a broader cleaning process rather than a standalone decontaminant.

Therefore, the use of chemical agents is essential in ensuring effective decontamination and plays a crucial role in maintaining hygiene and safety in surgical environments.
