COVID-19 Vaccine Production Facility Decontamination


Throughout the COVID-19 pandemic, ClorDiSys has been proudly helping essential businesses protect their workers and operations by providing contamination control solutions.  Recently, our Decontamination Services team assisted a contract manufacturer prepare their facility for the production and storage of COVID-19 vaccines.  This facility had previously been used in the production of a beta-lactam antibiotic, which offered the unfortunate possibility of cross-contamination of the beta-lactam used.  With anywhere from 10-20% of the general population having some allergic reaction to penicillin or other beta-lactams, the facility required a true complete decontamination in order to guarantee the safe manufacture and storage of the new vaccines.  In order to mitigate this risk, it was decided to treat the area using chlorine dioxide gas.  Having been shown effective against a variety of beta-lactams, chlorine dioxide gas presented a verified process of treating the entire environment.  In this case, the facility treated the environment after removing all prior equipment and before the installation of the new equipment.  The decontamination took place over the course of two days, and the facility was able to start installing equipment the next day.  We have always been proud of the work accomplished at ClorDiSys over the past twenty years and assisting in the safe production of vaccines to end the COVID-19 pandemic ranks pretty high up on our list of achievements.  Look for our blog post next week for more info regarding how we've assisted during the COVID-19 pandemic.

When a cannabis grow room is empty, that is the ideal time to implement a complete decontamination of the space. A complete removal of all microbial life including fungi, bacteria, spores, and viruses requires a sterilization-level process. A sterile environment from the start, as well as only sterile items being introduced into that environment, will help best assure lack of mold and other contaminants. A sterilization at the end of every harvest is also good insurance no pathogens will proliferate when the next crop starts.

Gaseous chlorine dioxide (CD) is an EPA registered sterilant that can be utilized prior to any plants enter the room to ensure any pre-existing mold spores or other microbial contaminants be remediated. For a complete kill of all potential organisms in the entire facility, chlorine dioxide gas is the optimal solution as it is a gas as room temperature, filling the entire space evenly and completely, decontaminating every surface, crack, or crevice with no residues or additional cleanup. CD gas is non-carcinogenic, non-flammable, and safer on materials than bleach, ozone, and hydrogen peroxide.

Ultraviolet light (UV-C) is an easy way to achieve high-level disinfection to any exposed surface in minutes. This chemical-free and residue-free disinfection method will help reduce mold spores, therefore minimizing future risk of exposure to the cannabis plant. This is best utilized in a completely clear space to ensure maximum exposure to the UV-C light. Ultraviolet light disinfection is a fast, simple to use method, capable of providing a 99% reduction of spores within minutes without any dangerous residues to be wiped down or neutralized afterwards.

Controlling mold and other microbial contaminants is essential to any operation as it is a strong threat to cannabis. Before plants enter the grow room, whether it is a new facility or at the end of harvest, measures should be taken to ensure no dangerous organisms are present that can result in wreaking havoc on the new crop.
