Abstract
An system is provided which, in one embodiment, utilizes an identification unit to identify the contents of a container and to transmit a coded identification signal to a remote receiver unit, thereby allowing emergency personnel or other interested persons to ascertain the contents of the container at an accident site. The identification unit includes a sensor positioned within the storage cavity of the container to detect whether a predetermined unsafe temperature or pressure condition exists therein. If the condition is detected, a coded identification signal, which may be in 8-bit binary form, is generated and transmitted. In an alternate embodiment, the identification unit is modified to answer an interrogation signal transmitted by a remote interrogation device when the interrogation signal corresponds to the material stored in the associated container.
