Canadian Oil and Gas Company to Monitor Evacuations via RFID
At a construction site in Newfoundland, the firm will be able to automatically identify the locations of thousands of workers during emergencies, by means of active RFID tags attached to hardhats.
Mar 28, 2014—
An oil and gas company is installing a solution to locate personnel in the event of an emergency at its construction site in Newfoundland, Canada, using radio frequency identification technology provided by systems integrator Focus FS. The system consists of active RFID tags, readers, exciters and software from GuardRFID Solutions.
During most emergency events, oil and gas workers and construction crews are instructed to report to mustering locations, where they can be accounted for and evacuated in a short amount of time. However, when hundreds or thousands of individuals need to be located within a minimal span of time, performing headcounts manually via paper and pen, or by scanning bar codes printed on ID badges, is not a very efficient method. The Newfoundland oil and gas firm (which has requested to remain unnamed) asked Focus FS to provide a personnel-evacuation system that would allow the locations of individuals to be identified during an emergency in an automated manner, thereby offering management a real-time view into where everyone onsite is located.
Focus FS knew that passive RFID would not provide the guaranteed, automatic tag reads required during an emergency, since passive technology's read ranges are not as long as the company needed to ensure all tag IDs would be captured as people moved through portals. (A system using passive RFID tags would have a 95 to 98 percent read accuracy, according to Jeff Brown, Focus FS' president, while one utilizing active tags could achieve closer to 100 percent.) At the same time, a real-time location system (RTLS) and battery-powered tags would require that readers be installed throughout the site. This, he says, would have been unrealistic since the site is often changing and moving. Instead, the GuardRFID system provides 433 MHz active AT-4 tags that remain dormant until awoken by 125 kHz low-frequency (LF) exciters at reader portals, at which time each tag transmits its own ID number, as well as that of the reader's exciter. GuardRFID's location-based Argus software then identifies the individual at specific chokepoints, such as entrances and exits to the site itself, as well as at locations where a person enters a new zone onsite, explains Zahir Abji, GuardRFID's president and CEO.
GuardRFID provided the Canadian company with approximately 14 readers and about 25 exciters, which are installed temporarily at locations where they are needed for the job at hand. The system can then be easily moved to another location if work requirements change. "This allows flexibility in the location of receivers and exciters," Brown states. "Chokepoints may change," and the hardware can then move with those chokepoints.
