Establishing Sterility in a New Facility

ClorDiSys' decontamination services take place primarily for contamination response, commissioning of new construction or renovated spaces, and routine preventive decontamination. The majority of what we do are large areas and entire facilities to get rid of widespread contamination problems and really give a baseline sterilization mark. With years of experience across a wide variety of industries and facility ages, we have a number of tricks and options to accommodate any project.

Recently our Decontamination Service team helped a biomedical research client who was moving into a larger building previously occupied by another company.  The building was renovated in order to handle the needs of the client, with a new ventilation system installed as part of that renovation.  Equipment was moved in from their previous location, and the ventilation system was balanced.  As the last step, the facility would undergo a chlorine dioxide gas treatment to provide a 6-log sterilization level kill before officially opening for research.  This enabled all of the equipment to be sterilized along with the building.  This is safer and faster than autoclaving everything in, as that process cannot be used on animal rack filters and most electronics.  Those materials typically do not receive a high-level decontamination if chlorine dioxide gas isn’t utilized as other liquid based decontamination methods are similarly incompatible.  The decontamination took place over the course of an 8-hour shift, with all process parameters being met to achieve the targeted 6-log sporicidal reduction.  Afterwards, the client was safe to start occupying the facility and begin their research.

Generally speaking, if the space can be sealed, it can be decontaminated. Some of the more common applications are buildings with unique layouts and multiple floors, processing and production areas, HEPA housing and ductwork, cold rooms, even tented pieces of equipment.
