Using RFID to Manage Evacuations
Citing the increased threat of terrorist attacks on commercial buildings, Axcess promotes its system as a way to track employees during emergencies.
Jun 17, 2004—Axcess, a Dallas-area provider of RFID-enabled personnel access control, asset management and surveillance systems, recently marketing a new use for its RFID tag system, ActiveTag: emergency-evacuation management. The ActiveTag system, which is in use by the U.S. military to track vehicles, personnel and missiles, as well as being tested by businesses, was designed to help track movement of office personnel for security reasons. But the company maintains that its system can provide an effective way for businesses and organizations to track their employees’ evacuation of a facility in the event of a fire or some other disaster.
The ActiveTag RFID tags, which are battery-powered and comply with the ISO 7810 ID-1 standard for access control cards, are more expensive than their passive counterparts, but the ActiveTag system enables reliable “hands-free” identification—the ability to identify personnel without the physical presentation of a credential, says Axcess CEO Allan Griebenow.
Axcess RFID tags can also be affixed to employee vehicles and office equipment, and read by readers at doorways, gates or even hallways and elevator entrances. Griebenow adds that the system can be used in conjunction with motion detectors to notify security about unauthorized movement in the building. Motion detectors, for example, can trace the presence of a person who is not carrying an RFID tag and alert security that an unauthorized person is in the office and where that person is.
The ActiveTag system, Griebenow says, has been tested for its mustering capabilities at a U.S. Department of Defense research facility. Although Axcess has been working with the technology for the past two years, use of the ActiveTag RFID system in offices has been limited.
“Security systems are driven by cost,” Griebenow explains. While a passive RFID tag may cost 30 cents, the ActiveTag battery-powered tag averages $20. On the other hand, ActiveTag RFID readers are considerably less expensive, averaging about $1,000 each.
Griebenow adds, however, that the efficiency and accuracy of the ActiveTag makes it the reliable choice for emergency evacuation management and will increasingly become the more popular choice for large companies. To date, a company’s decision to purchase and deploy an emergency evacuation management system, such as the ActiveTag’s, is “usually driven by a problem or a foreseeable problem,” Griebenow says. He argues that the notion of a potential disaster risk has been changed by the increased threat of terrorist attacks that target commercial sites.
