CRCST Practice Exam

Which of the following packaging material is compatible with hydrogen peroxide gas plasma sterilization?

1. Cotton

2. Aluminum

3. Polyethylene

4. Tyvek

The correct answer is: Tyvek

Tyvek is the correct answer because it is a packaging material that is compatible with hydrogen peroxide gas plasma sterilization. Tyvek is a non-woven, high-density polyethylene material that is breathable, allowing for the penetration and removal of the sterilant gas during the sterilization process. This property makes Tyvek a suitable choice for packaging items that will undergo hydrogen peroxide gas plasma sterilization. In contrast, the other options are not ideal for hydrogen peroxide gas plasma sterilization. Cotton is not compatible as it may absorb the gas, leading to incomplete sterilization. Aluminum is not breathable and may inhibit the penetration of the gas. Polyethylene is also not breathable and may not allow for proper gas penetration and removal during the sterilization process.
