Decontamination Efficacy of Three Commercial-Off-The-Shelf (COTS) Sporicidal Disinfectants on Medium-Sized Panels Contaminated with Surrogate Spores of Bacillus anthracis
In the event of a wide area release and contamination of a biological agent in an outdoor environment and to building exteriors, decontamination is likely to consume the Nation’s remediation capacity, requiring years to cleanup, and leading to incalculable economic losses. This is in part due to scant body of efficacy data on surface areas larger than those studied in a typical laboratory (5×10-cm), resulting in low confidence for operational considerations in sampling and quantitative measurements of prospective technologies recruited in effective cleanup and restoration response. In addition to well-documented fumigation-based cleanup efforts, agencies responsible for mitigation of contaminated sites are exploring alternative methods for decontamination including combinations of disposal of contaminated items, source reduction by vacuuming, mechanical scrubbing, and low-technology alternatives such as pH-adjusted bleach pressure wash. If proven effective, a pressure wash-based removal of Bacillus anthracis spores from building surfaces with readily available equipment will significantly increase the readiness of Federal agencies to meet the daunting challenge of restoration and cleanup effort following a wide-area biological release. In this inter-agency study, the efficacy of commercial-of-the-shelf sporicidal disinfectants applied using backpack sprayers was evaluated in decontamination of spores on the surfaces of medium-sized (∼1.2 m2) panels of steel, pressure-treated (PT) lumber, and brick veneer. Of the three disinfectants, pH-amended bleach, Peridox, and CASCAD evaluated; CASCAD was found to be the most effective in decontamination of spores from all three panel surface types.

Anthium Dixocide disinfection FAQs {Bleaching effect on clothes} "To transport use solution from one job site to another the remaining solution should be placed in a smaller container that is liquid full or with minimal headspace and placed in a cool temperature-controlled environment. ClO2 will leave solution and accumulate in the available headspace with agitation during transport. Transporting use solution could lower the concentration of the solution below the effective concentration required for disinfection. We do not recommend storing use solution. "
{Includes acid type as relates to pH and chlorine dioxide solution final concentration} "ClO2 will leave solution with agitation during transport. It is important to minimize headspace" "pH may be low and it may cause browning of the foliage if left to dry." "Can I break the product into smaller containers for application? If you are an Applicator with a simple label, SDS, and an emergency number, you can activate any quantity required utilizing the formulation 1 part Anthium™ Dioxcide, 5 part 10% acid activator, wait 15 minutes, dilute with 56 parts water."
Chlorine better than Chlorine Dioxide (in wastewater at least for SARS) Study on the Resistance of Severe Acute Respiratory Syndrome-Associated Coronavirus
