How Are Chlorine Dioxide Treatments Completed?
Production of the on-site generated gas is outside the treated space and introduced through application lines. This helps to reduce possible exposure. Concentrations inside the treated space are monitored for efficacy, and outside for safety. Removal of sensitive equipment is not necessary because there are no known adverse effects from chlorine dioxide gas.
Chloride Dioxide gas is effective against a wide range of bacteria, viruses, fungi, and molds. Similarly, this gas can even successfully control bacteria that form spores. Performance of bacterial swabs before and after the treatment can assess the effectiveness of treatments. Placement of biological indicators throughout the treated areas will as well.
Set up for treatment requires sealing the treatment area and setting up fans for even distribution of gas. Set up also includes increasing the humidity to around 65%. Actual treatment time is typically six hours or less once the area is sealed and humidified. Assess efficacy by monitoring and achieving a concentration-time (CT) value known to be effective against pathogens from lab studies. Bioassays and swabs are also an option to confirm efficacy. The gas aerates quickly allowing the facility to be up and running promptly. Completion of most CD treatments takes less than one day. Chlorine Dioxide sterilizes almost any size area including tarped equipment, small rooms, spiral freezers or even large processing facilities.
Above all, IFC’s knowledge and experience in food plants assures regulatory compliance and high standards of safety.
