How RFID Helps in Emergency Evacuation?

Whether it is a construction site, factory, a sensitive sector, or a corporate building, the process of building evacuation needs to be simple. Every business, big or small, has an evacuation plan, fire escape signage, and route maps. But RFID helps to take it to the next level. RFID tags are attached to your employees or residents, so they can be monitored in real-time during an emergency. RFID emergency evacuation plays an important role in maintaining utmost safety parameters during an evacuation process.

Let us understand the workings of an RFID that helps in emergency evacuation.

Working of an RFID Reader to Evacuate Buildings

RFID readers and RFID cards are basic components of RFID Emergency evacuation systems. The principle of operation is that RFID tags send signals which activate the RFID cards nearby or at a distance. Thus, when signals from RFID cards reach a sensor or a Reader the information on the card is translated.

There are two types of RFID card systems: active and passive RFID tags. In an active RFID card system, the power source is directly connected to the RFID card. Sensor tag operates at a frequency of 2.45GHz and a range of operational temperatures of -50°C to 150°C.

The longevity of such a power source is 4 years due to a low operational power requirement of 12-18µA. When a power or some emergency breaks out the alarm systems are automatically activated or a person activates them. Sensor tags for the RFID Emergency Evacuation system start sensing the path and number of active RFID cards responding to the signals it releases.

You may also use software which shows them the best path using the distance between the sensor and the card. This visual for finding exit routes can be on the phone of the employees. The employees can simply follow the route and proceed to get into the safe zone.

In addition to that, some RFID card readers can also get information about the temperature of a person’s surroundings. Best routes can also be planned by the temperature differences so that a wrong path is not shown to the employees.

The passive RFID card readers may also be incorporated in the turnstile systems that help to identify the employee leaving a facility and rescue efforts can divert their efforts for employees who could not get out. Getting a passive turnstile gate also plays an important role in RFID in emergency planning.

Benefits of Having RFID Systems for Evacuating Buildings

There are some benefits of using RFID emergency evacuation systems which help to smoothly evacuate employees. However, there are some other benefits of using RFID systems for evacuation efforts in a building or an enclosed area:

a. Distress Buttons

Some of the RFID cards have an integrated ‘Distress’ button attachment that helps to relay distress buttons. Due to low power consumption, these buttons can last over 8 years without changing battery.

Thus, RFID card readers help send out an alarm system which can efficiently help in the evacuation process. Thus, such a distress button helps to pinpoint your exact location.

b. Active RFID Systems With UHF Technology

Active RFID systems operate in ultra-high frequency bands, and they have a range of up to 100 metres. Using such a high-range system there are two types of UHF RFID, transponders and beacons. RFID emergency evacuation systems that have transponders are only active when they are near an RFID reader due to radiofrequency waves.

With beacons or real-time locating systems, the signals are useful for tracking an exact location of a bearer. Therefore, on the off chance that you get stuck, using an RFID beacon can help to understand the location of that person.

c. Integration With Analytics and AI

The data from an RFID system can be used in an AI (Artificial Intelligence) to smooth up the evacuation.

The AI can detect and identify hot zones using RFID card reader data and helps the AI make pre-planned evacuation plans for quick movement at times of distress. Thus, AI and RFID Emergency Evacuation systems can work together to create a safe path.

Apart from that, it is a contactless solution that helps in personnel tracking and maintaining safety systems for employees.

Future of RFID in Tracking Building Occupants

The future of RFID trackers in building occupancy measurement and safety parameters is evolving. Not only the RFID trackers can help in accessing information about the number of occupants but also their identity. This way it helps to maximise utility of evacuation services and increase the safety of a facility.

Some of the futuristic applications of using RFID emergency evacuation systems can be:

1. Creating Heat Maps

RFID technology can help to identify and predict a pattern by using AI data processing systems to create heat maps. These heat maps can affect ways an evacuation unit moves through the building and help in evacuating the people in distress.

2. Using RFID and Cloud Database for Path

RFID chips with transponder-receiver communication also help to build pathways that can help in self-evacuation. An RFID chip with BLE (Bluetooth Low Energy) can work in conjunction to create a path based on danger zones, or shortest distance to an exit.

3. Enumerating the Exits

Exit ways of big institutions generally have turnstile or access control solutions. The role of RFID in emergency planning can be implemented by making sure that access control gates can read RFID cards. Thus, you can easily track their movement and ask rescue persons to search for specific persons. These specific persons may have trapped themselves somewhere.

Wrapping up, the use of RFID emergencies in evacuation can be useful for streamlining evacuation efforts. Concept behind is simple as it counts and tracks persons that are trapped inside. RFID can also help to monitor and create shortest pathways to an exit gate for times you are in an emergency.

RFID technology with evacuation systems present in buildings and AI can streamline rescue efforts.
