Claim 14:
15. A system comprising:
a memory storing an exposure application;
a pattern store storing known chemical patterns, each of the known chemical patterns corresponding to a known chemical or a known combination of chemicals, and a processor, wherein the exposure application, when executed on the processor, configures the processor to:
receive a plurality of sensor readings from a plurality of chemical sensors via a communication device associated with an individual, wherein each chemical sensor of the plurality of chemical sensors is configured to detect a different chemical;
determine a cross-sensitivity pattern from the plurality of sensor readings;
determining which chemical or chemicals from a list of chemicals that may be present at allocation of the plurality of chemical sensors based on a cross-sensitivity of each chemical on the list;
compare the cross-sensitivity pattern with one or more of the known chemical patterns wherein the one or more known chemical patterns include chemicals patterns for the chemicals in the list;
determine that the cross-sensitivity pattern matches one of the known chemical patterns;
identify a chemical or combination of chemicals giving rise to the cross-sensitivity pattern based on determining that the cross-sensitivity pattern matches the one of the known chemical patterns;
receive, from the communication device, a determination by the communication device of the presence of a current type of personal protective equipment by the individual and compliance with proper positioning of the personal protective equipment by the individual;
determine, an exposure threshold level for the individual based on the determined current type of personal protective equipment, the determined compliance with the proper positioning of the personal protective equipment associated with the individual, and the identification of the chemical or combination of chemicals giving rise to the cross-sensitivity pattern;
monitor an exposure value of the individual to the identified chemical or combination of chemicals giving rise to the cross-sensitivity pattern; and
when it is determined that the exposure value exceeds the exposure threshold level for the individual, send to the communication device a warning on the presence of the chemical or combination of chemicals including a notification to use a particular type of personal protective equipment.
