Smartchoice: a decision app for chemical handheld detectors

This paper provides an overview of the development of an application designed to support the decision-making process for chemical detection devices, with a specific focus on their utility in countering the malicious deployment of chemical agents. The research begins by highlighting the critical need for dependable and swift chemical detection capabilities in the context of both deliberate acts of chemical terrorism and accidental releases during Natech events. In such scenarios, prompt response measures are indispensable to mitigate harm and safeguard human lives and the environment. To assess the acceptability of such an application, a comprehensive survey involving first-line responders, and hazmat teams, was conducted. The survey results indicate unanimous consensus among responders regarding the significant value of the application. The research explores the attributes and detection methodologies associated with specific selected detector technologies, based on the determination of minimum parts per million (ppm) levels. Additionally, the research investigates the correlation between specific olfactory or visual signs, which could potentially serve as input data for the proposed handheld chemical detection application. The ultimate objective of this research is to recommend the most suitable handheld chemical detector. This research underscores the interdisciplinary nature of the research, bringing together fields such as chemistry, physics, environmental science, and emergency response to address the pressing need for advanced handheld chemical detection in the contemporary era.
