What is the recommended relative humidity of central service sterile storage?

The recommended relative humidity for central service sterile storage is crucial for maintaining the integrity and sterility of medical instruments and supplies. A relative humidity level of less than 70% is advisable because excessive moisture can create an environment conducive to the growth of mold, bacteria, and other microorganisms, which can compromise the sterility of items. Furthermore, high humidity levels can also lead to corrosion of metal instruments and can affect the integrity of packaging materials.

Maintaining relative humidity at less than 70% helps to ensure a balanced environment that prevents microbial growth while avoiding negative impacts on the materials stored. This practice is part of the broader guidelines for sterile processing areas, which aim to enhance patient safety and improve outcomes by ensuring that sterile items remain uncontaminated until use. Proper humidity control, along with adequate temperature regulation, is essential in providing an optimal storage environment for sterile products.
