Abstract: A method for detecting chemical vapors includes acquiring an environmental air sample within at least one fielded chemical detector, detecting that at least one chemical from a selected set of possible chemicals is present within the environmental air sample, analyzing data relating to the detecting, determining at least one of a chemical name, a chemical concentration, a chemical category, or a toxicity level, and transmitting the determined information to a central data collection site.

Abstract: The present disclosure generally relates to chemical threat detection, and more specifically, to a wearable chemical threat detector for an indoor or outdoor environment. In one embodiment, a method for chemical sensing and detection is disclosed. The method includes (a) deploying a plurality of wearable chemical detectors, (b) receiving an environmental air sample by at least one of the plurality of wearable chemical detectors, (c) receiving an alert of one or more chemical(s) present within the environmental air sample from at least one wearable chemical detector, (d) analyzing the alert for data relating to at least one of a chemical name, a chemical concentration, a chemical category, or a toxicity level, and (e) transmitting the data to a central data collection site. Furthermore, the embodiments disclosed may provide a warning and/or an evacuation route to a user once a threat is detected.
