When lone workers sound the alarm for help, swift support is essential. Therefore, knowing where workers are can help your response team locate them faster, saving crucial time in an emergency.
Many lone worker solutions provide GPS/GNSS location that can detail a user’s location accurately on a mapping service, like google maps. However, GPS/GNSS doesn’t always work well indoors because the signal to the satellite can be blocked, and the mapping service isn’t granular enough.
As a result, the location provided can be the last-known position outside the premises or a fix inside but lacking any detail to be any use to a response team.
Therefore, if you require something more dependable you may wish to consider other location methods. In this blog we’ll discuss what options are available in the market that enhance the safety of lone workers.
Beacon location
Beacons strategically placed throughout the site serve as location markers for lone workers. When a worker walks past a beacon it automatically updates their handset with its position. In the event of an alert, the alarm message includes the location of the last beacon the worker passed, stored in their handset. This information is then displayed on a site map for the response to easily identify. Additionally, some solutions may also run a quick scan for the nearest beacon too in case there is a closer one that the user hasn’t reached.
These beacons come in different versions, indoor, outdoor, ATEX as well as battery or mains powered. They connect to 4G handsets via Bluetooth or DECT handsets using LF or DECT frequency.
The more beacons used the more accurate the location is. However, even with a small number they can reduce the search time by indicating which building or floor the lone worker is located.
Our solutions including Aspect Link, IP DECT and VoWiFi fully support the use of these essential beacons.
Base Station (WiFi and DECT) Location
Utilising private voice or data networks with DECT base stations or Access Points (both commonly referred to as base stations) can also provide indoor location information.
When an alarm is raised, handsets like DECT, smartphones, and VoWiFi can indicate the specific base station they are connected to, providing a general location of the user within approximately a 30-meter radius. This data can then be showcased on a site map to help the response team.
While base stations may have a wider coverage area that can extend across multiple floors or external spaces, when combined with Beacons, they can enhance accuracy by narrowing down the search area to a particular floor or section of the building. This coupling of Beacon and Base Station technologies can significantly improve location accuracy in emergency situations.
Light and Sound on Lone Worker Device
Some lone worker devices can emit a light and audible sound once a man-down alarm has been raised, making it easier for responders to locate their colleague in an emergency. When searching large areas quickly, individuals may be easily overlooked, especially if they’re lying low or concealed behind equipment or fixtures.
However, the sound generated from the device can draw a responder’s attention once they’re in the vicinity, making them aware they’re nearby and prompting a thorough search. Additionally, the emitted light makes the worker more visible, further assisting in their quick rescue.
User Named Location
Another option is to motivate users to get in the habit of detailing their location as and when they undertake a task alone. This works well for users that are in one or two locations each day.
Apps like Atlas SOS streamline this process for users, making it effortless to input their task duration and location details on the timer screen.
In the event of an alarm, responders receive the alarm message containing the user's name, contact number, and precise location details.
Push to Talk Technology
In times of need, responders can all work together to help locate their colleague by using, either Radio or Cellular based, Push to Talk (PTT) technology that allows them to communicate over a signal channel.
PTT technology works well in emergency situations as it allows teams to designate tasks and provide updates all-on-the-go. Users simply push a button on their handset to broadcast their message to their team, who can respond in a similar manner.
By using PTT response teams can spread out and check different areas simultaneously, whilst keeping each other updated so not to duplicate efforts or miss certain places. By working together effectively in a coordinated effort can help to save crucial time when locating a colleague.
Summary
As you can see there are various options available to enhance lone worker safety. Technology can help by providing accurate location information to responders on site maps.
You can also get lone workers to input their location before they start a task using an easy-to-use app or provide lone worker devices that emit a light or sound that will reveal their location when responders are nearby.
Furthermore, Push to Talk Technology can speed up your response efforts by helping your responders search more efficiently in a coordinated fashion.
