Evaluation of Sporicidal Wipes and Liquid Agents for Decontamination of Anthrax-Contaminated Surfaces by Robotic Cleaners [open pdf - 1MB]
"In 2001, U.S. Postal Service system facilities were contaminated through the introduction of a few letters containing 'Bacillus anthracis' (anthrax) spores. The likelihood of occurrence of another such incident has prompted the U.S. Environmental Protection Agency (EPA) to develop strategies, guidelines, and plans for decontaminating persons, equipment, and facilities to mitigate the risks of contamination after a biological weapons attack. [...] The use of commercially available robotic cleaners is a potentially effective decontamination technique for the complete removal or inactivation of 'Bacillus (B.) spores'. This report discusses a project that investigated the ability of robotic cleaners to apply sporicidal liquid/wipe to floor surfaces and inactivate/remove 'B. atrophaeus' spores, formerly known as 'B. globigii', as a surrogate for anthrax spores. Specifically, this report addresses the operational aspects of decontamination using robotic cleaners for large surface areas tested under conditions that mimic their realistic field use. This project evaluated the robotic cleaners for deactivation of 'B. atrophaeus' on two test material surfaces: laminate and vinyl."
