Abstract:
1. A method of identifying a presence of toxic waste that presents a health hazard, the method comprising: adding multiple Radio Frequency Identification (RFID) tags to toxic waste that is produced in a facility, wherein the multiple RFID tags are suspended unadhered to the toxic waste in a colloidal state; wherein the RFID tags store and communicate Electronic Product Code (EPC) information about the toxic waste and the EPC information comprises one or more of: a description of the chemical composition and makeup of toxic waste; a name, location, and emergency contact information for the facility that produced the toxic waste; and a Material Safety Data Sheet (MSDS) that contains regulation-required information about composition, emergency containment procedures, first aid procedures and other relevant information related to the toxic waste; wherein the RFID tags provides information which describes: a composition of the toxic waste; when and where the toxic material was generated; emergency contact information regarding persons with technical knowledge about the toxic material; and emergency procedures, including MSDS information; scanning, with an RFID sensor, an area for the RFID tags; in response to detecting the RFID tags in the area, determining that the toxic waste has been introduced into the area; and determining the composition of the toxic waste by scanning the area in which the toxic waste is present; wherein the information contained by the RFID tags and returned to the RFID sensor by the RFID tags when scanning the toxic waste enables a HAZMAT team to immediately identify/determine by reading the information returned from a scan of the electronic tags important information including at least: (a) what toxic material is in the spill, (b) how to contain the toxic material, and (c) what safety precautions to take.
