Decontamination following a chemical, biological, radiological, or nuclear (CBRN) event involves a well-integrated approach to contain and, just as importantly, clean up after the threat. Decontamination of a biological event occurs in three stages: the immediate, critical incident response; the consequence management phase; and remediation to reinstate the area to a level deemed safe for human re-occupation. Decontamination efforts typically include cleaning and disinfection of material objects, equipment, people and the surrounding environment. Methods for large area decontamination used currently, for example gaseous formaldehyde, have several drawbacks including carcinogenicity and environmental toxicity of the agent employed, labour intensiveness of the process, corrosiveness of the agent to metal surfaces and its incompatibility with electronic equipment. Dry fogging system (DFS) technology has been identified as a potential safe, robust, portable and efficacious decontamination method for biological agents, both for targeted threats and in industries where decontamination of biological contaminants is a routine concern. Although such systems have been commercialized and fielded, the technology readiness level (TRL) for dry fogging systems for application in emergency response is estimated at between levels 4 and 7, based on the significant knowledge gaps on capabilities in many actual applications of interest, due to lack of appropriate validation activities. Therefore
