CRCST Practice Exam

In a sterilization equipment room, what is the ideal humidity range?

1. 10%-30%

2. 20%-50%

3. 30%-60%

4. 40%-70%

The correct answer is: 30%-60%

In a sterilization equipment room, the ideal humidity range is 30%-60%. This range helps to prevent the potential for rust and corrosion on the equipment while still maintaining a suitable environment for effective sterilization processes. Humidity levels outside of this range may compromise the integrity of the sterilization equipment or impact the sterilization process itself. Option A (10%-30%) is too low and may not provide enough moisture to prevent rust and corrosion effectively. Option B (20%-50%) falls slightly below the recommended range and may not offer enough humidity for optimal equipment storage and use. Option D (40%-70%) exceeds the ideal range and could potentially introduce too much moisture, leading to issues with the equipment and the sterilization process.
