Abstract: A secured system for fire suppression refill and recovery and a method for using such system. Operation of the system involves the refilling of an extinguisher tank with matter from a storage tank, the recovery of matter from an extinguisher tank to a storage tank, the cleansing of matter within a tank, and the purging of matter from a tank. The system includes a secure recovery unit, secure tank units, and equipment for connecting the recovery unit to the tank units. The system is configured such that, during its operation, safety and security risks commonly associated with the transfer of matter to and from extinguisher tanks are greatly reduced.

Abstract: Agent verification can be performed by initially embedding definitive identification and parametric information regarding the vessel into a sensor set. The integrated sensor set, with a communication means, is incorporated into the vessel and/or its integral components to detect the current state of the vessel and its content. The information and sensor set can be normally passive or normally dormant, and can be activated by means of an external stimulus. Positive determination of the integrity of the vessel and its content is accomplished by interrogating the sensor set for detecting the current parameters and comparing the status of the vessel and its content against the initially embedded information using an external instrument. A match signifies a validation and the absent of a match signifies a non-valid condition. The method of providing indication of a valid or a non-valid condition can be accomplished by any means available, electronically or otherwise.
