System and method for distribution of sensors for emergency response
First Claim
1. A system for selecting placement of sensors for sensing a hazardous substance released from a plurality of hazard points, the system comprising:
- a processor; and
a memory, wherein the memory has instructions stored therein that, when executed by the processor, cause the processor to;
identify a location of a hazard point;
identify a fenceline surrounding the hazard point;
identify a toxic level of concern (LOC) for the hazardous substance;
calculate a minimum amount of the hazardous substance (Q) for which a concentration at a centerline of a plume carrying the hazardous substance reaches the toxic LOC at the fenceline;
simulate a release of the hazardous substance in the calculated amount Q from the hazard point;
calculate, based on the simulated release, locations of a pair of sensors where concentration is substantially equal to a minimum level of concentration detectable by the pair of sensors; and
output the locations of the pair of sensors for prompting placement of the pair of sensors at the locations.

Abstract
A system and method for placement of sensors for sensing hazardous substances released from a plurality of hazard points. A processor identifies a location of a hazard point, a fence line of the plant-site, and a toxic level of concern (LOC) for the hazardous substance. The processor calculates a minimum amount of the hazardous substance (Q) for which a concentration at a centerline of a plume carrying the hazardous substance reaches the toxic LOC at the fenceline, and simulates a release of the hazardous substance in the calculated amount Q from the hazard point. The processor further calculates a pair of sensor locations where the concentration of the plume is equal to the minimum detectable concentration level of sensor based on the simulated release. The pair of sensor locations is then output by the processor.
