What can cause oxidation in materials, according to the text?

• A. The use of high alkaline detergents
• B. The application of extreme heat
• C. The exposure to high humidity
• D. The presence of sunlight

Answer: (A)

Oxidation in materials, particularly in the context of surgical instruments, can indeed be influenced by the use of high alkaline detergents. These detergents can create an environment that leads to the breakdown of the material's surface properties, allowing for reactions with oxygen. High alkaline conditions can accelerate the process of corrosion on metals, thereby promoting oxidation. This is particularly notable in stainless steel instruments, where the protective chromium oxide layer can become compromised, making the instruments more susceptible to rust and degradation.

While other factors like extreme heat, high humidity, and the presence of sunlight can also contribute to oxidation, high alkaline detergents are a significant agent in the sterilization and cleaning processes within surgical settings. Understanding the impact of cleaning agents is crucial for maintaining the integrity and longevity of surgical instruments.
