Show moreA monitoring system for chemical shipments having an apparatus for detection of a leak from a shipment vessel having a shroud. A first chemical sensor is in communication with a chamber of the shroud for detecting the presence of a substance leaking from the vessel. A second sensor is in communication with the ambient environment surrounding the shroud. A monitoring circuit in communication with the first chemical sensor and the second chemical sensor monitors a first chemical sensor output and a second chemical sensor output and signals an information unit dependant on the increase of at least one of the first and second chemical sensors. The information unit emits a signal to an alarm or output device in response to an increase of the magnitude and/or rate of increase of at least one of the first chemical sensor output and the second chemical sensor output. A physical sensor can be in combination with the monitoring circuit. The information unit can be a remote information unit to which the monitoring circuit signals by wireless communication means.
