In various embodiments, methods of treating a space to reduce a concentration of volatile organic compounds present in the space using chlorine dioxide are provided. A method can include application of aqueous and gaseous chlorine dioxide solutions within the space or to materials located within the space. Treatment of materials that emit volatile organic compounds with chlorine dioxide can reduce the emission rate or shorten the volatile organic compound emission cycle of the material. Soft surface substrates such as carpeting materials can be treated with chlorine dioxide to reduce volatile organic compound emission and/or to reduce the number of microorganisms present in the material.

A method of operating a sterilizer includes imaging a load of instruments to obtain an optical image and/or thermal image of the load, and selecting a sterilization cycle to be performed by the sterilizer based on one or more characteristics of the load determined from the image of the load. The characteristics may include the number of instruments, the presence of a diffusion-restricted space, the volume of the load, and the temperature of the load. The method may further include adjusting the sterilization cycle based on the characteristics of the load.
