Lone worker protection

Lone worker protection (LWP) is a set of features implemented across the TASSTA solution components to meet codified safety requirements, defined in the DGUV 112-139 standard (view in PDF format) and other regulations. These requirements are developed specifically for lone worker users, who work by themselves without close or direct supervision.

If you are a lone worker, we hope you will appreciate the safety features that T.Flex provides and the way it keeps you connected to your team.

Important:

To ensure the correct functioning of all LWP features, switch T.Flex app to priority mode. Refer to your device manual for details.

Before you start using the LWP features, confirm that the administrator has enabled them for you in T.Commander. If LWP is enabled for you, you are prompted to perform a sensor check as soon as you log in.

LWP has three states:

  • Disabled and Inactive
    LWP features are not applied to your user account.
  • Enabled and Inactive
    LWP features are applied to your user account, but they are not working properly. For example, this can happen if the sensor check has failed or the dispatcher has gone offline.
  • Enabled and Active
    LWP features are applied to your user account and working properly.

To view your LWP settings, tap Emergency in the navigation drawer and select LWP settings.

All emergency messages created by LWP features are kept only in the emergency journal.

Dispatcher presence:

The Dispatcher option enables a mode in which the lone worker is supposed to work under direct supervision of a dispatcher who is running T.Rodon. This option is enabled by the administrator in T.Commander.
In this mode, T.Flex constantly checks if the dispatcher is online. On login, you won't be able to pass the sensor check if the dispatcher is offline. If the dispatcher goes offline while you are logged in, you get a warning signal, and LWP features change their state to Enabled and Inactive.

To ensure maximum safety, LWP provides the following functionality:

  • Periodic check
  • Man down
  • Movement
  • Detect impact
  • Battery control
  • Connect/Disconnect monitor
  • Emergency contact
Notes:
  • Lone worker protection is provided by a dedicated service on the TASSTA server. When the server or this particular service is turned off, you receive a notification about disconnection from the LWP server and a short vibrating signal. The same happens when LWP functionality is turned by the operator in T.Rodon.
  • Your user account settings may be such that all of the LWP functionality is turned off while the device is charging. This is configured by the administrator in T.Commander.
Warning:

Use lone worker protection alerts strictly as emergency features. This will help you receive timely assistance if you experience an emergency situation.

Sensor check

The sensor check certifies that the device is ready to work in lone worker protection mode. At its core, the sensor check is a series of tests that verify the basic functionality of LWP. When you see the Sensor Check Validator popup, follow the instructions on the screen.

The sensor check is done in the following situations:

  • On the first launch of T.Flex on the device if LWP is enabled for your user account
  • When you log in on a different device from your previous one
  • When the T.Rodon operator starts it for you
  • After 23:30, 23:45, 24:00

You can also start the sensor check using the emergency screen in the top right corner.

Notes:

If you lose connection with the server and your emergency occurs in an offline state, then the emergency will be initiated upon reconnection with the server.
If the application exits correctly, all notifications in the status bar are deleted.

Periodic Check U

The Periodic Check U feature is a way to make you repeatedly confirm that you are OK. It provides a popup dialog at regular intervals that are set by the command and control center operator in T.Rodon. The dialog pops up no matter which T.Flex screen you are using. When T.Flex is closed while you are still logged in, the popup dialog appears over other apps. Furthermore, T.Flex can unlock the device to show the popup. The popup dialog says, "EVERYTHING FINE? CLICK TO CANCEL ALARM" and starts a countdown. You have until the end of the countdown to tap the popup, confirming that you are not incapacitated. If you fail to submit the OK status, an emergency call starts and an emergency message is sent.

Periodic Check U is a T.Flex feature and cannot be enforced by the administrator or dispatcher. It is up to you when to activate it.

Periodic Check U is based on a combination of two timers: Check Time and SOS Timer (auto).

  • Check Time
    This is the time interval (in seconds) between checks. The minimum value is 20 seconds, and the maximum value is 86400 seconds (24 hours). Check Time is restarted every time you successfully pass the check.
  • SOS Timer (auto)
    This time interval (in seconds) specifies how quickly you need to respond when prompted (by the "EVERYTHING FINE?" popup) to confirm that you are safe. The minimum value is 20 seconds, and the maximum value is 86400 seconds (24 hours). If this time elapses without your response, an emergency is triggered.

To activate the feature, open Emergency in the navigation drawer and select Periodic Check U. Tap Periodic Check U symbol to start the timer. If you minimize the application, the timer will continue. If you fail a check and an emergency call is made as a result, the checks stop. To use this functionality again, re-enable it.

If the administrator turns off the LWP feature set for you while your Periodic Check U timer is running, the timer stops and no emergency call is triggered.

The timer does not depend on the connection to the server and continues whether or not the server is available. If the Check Time timer expires while you have no connection to the Internet, you still need to cancel the emergency in the popup.

When connection is lost, a special audio signal may be played. This is configured by the administrator in T.Commander. However, if LWP is enabled for you, the lost connection alarm is sounded whether or not the option is turned on in T.Commander.

Man Down

Automated Man Down alerting has proven to be an effective way to make the workplace safer for all employees. If an employee encounters a hazardous or a life-threatening situation, an automatic Man Down alert can be used to let the appropriate personnel know that a dangerous or life threatening situation has occurred. In the event of an emergency the assigned personnel can take action immediately after receiving the emergency alert.

The accelerometer on the mobile device is used for detecting an impact, and a Man Down alert is sent to the group. Once the application detects that the phone is in a horizontal position (for a defined period of time), a popup dialog saying "EVERYTHING FINE? CLICK TO CANCEL ALARM" is automatically displayed. To send the OK status, tap this popup. If the worker doesn’t send the OK status, an emergency call starts and an emergency message is sent.

The Man Down feature is based on the following three parameters:

  • Degree
    If the device falls and the accelerometer reports that the device tilt has exceeded a certain angle (the value can be set in the range from 0 to 90) T.Flex starts the Tilt Timer.
  • Tilt Timer
    If the device remains at an angle that exceeds the threshold value until this timer expires, the app goes into a warning state. The timer can be set to a value between 0 and 86400 seconds (24 hours).
  • SOS Timer (auto)
    This time interval (in seconds) specifies how quickly you need to respond when prompted (by the "EVERYTHING FINE?" popup) to confirm that you are safe. The minimum value is 20 seconds, and the maximum value is 86400 seconds (24 hours). The default is 30, and the value is configured in T.Rodon or T.Commander. If this time elapses without your response, an emergency is triggered.

Movement

Movement monitoring uses location data from the mobile device’s acceleration sensor to detect lack of movement, which may mean that the worker is hurt. In this situation, an emergency alert is triggered and an emergency call is made. The emergency alert includes the user name, group membership and GPS coordinates with a link to the exact location on the map. Automatic no-movement alerting has proven to be an effective way to create safer workplaces.

The Movement feature is based on two timers:

  • Inactivity Timer
    If the device remains motionless for a period of time, an Inactivity Timer starts. If any movement occurs within this time, the timer is cancelled and T.Flex goes back to its regular operation. The default setting is 60 seconds, but it can be set in the range from 0 to 86400 seconds using T.Rodon or T.Commander.
  • SOS Timer (auto)
    This time interval (in seconds) specifies how quickly you need to respond when prompted (by the "EVERYTHING FINE?" popup) to confirm that you are safe. The minimum value is 20 seconds, and the maximum value is 86400 seconds (24 hours). The default is 30, and the value is configured in T.Rodon or T.Commander. If this time elapses without your response, an emergency is triggered.

Impact detection

Important:

The device must have an accelerometer for this feature to work.

The Detect Impact feature watches for sudden physical impact on the device (and, by extension, on the user). T.Flex uses the accelerometer to distinguish between motions that would be characteristic of normal activities such as walking and irregular jolts that could mean falling, struggling or tumbling downstairs.

As soon as the impact threshold which is set in LWP Plugin on T.Rodon, the user receives a notification, EVERYTHING FINE? When T.Flex is closed but a worker is still logged in, a pop-up dialog appears over other apps. If the worker’s device is locked, T.Flex can unlock the device and pop-up will appear. The pop-up dialog consists of a text EVERYTHING FINE? CLICK TO CANCEL ALARM worker can click on this pop-up to send OK status. If worker doesn’t send OK status, Emergency Call will start and emergency message will be sent.

The Detect Impact feature is based on the following parameters:

  • Impact Threshold
    This value is set from 1 to 40, where 1 is the maximum sensitivity, and 40 is the minimum sensitivity.
  • Impact Time
    For the Impact feature to be triggered, the device must experience the threshold (or higher) acceleration for at least this long. The value is in milliseconds. The recommended value is 2 to 3, but performance may vary depending on the type of accelerometer. You should check what value is acceptable for your particular device.
  • SOS Timer (auto)
    This time interval (in seconds) specifies how quickly you need to respond when prompted (by the "EVERYTHING FINE?" popup) to confirm that you are safe. The minimum value is 20 seconds, and the maximum value is 86400 seconds (24 hours). The default is 30, and the value is configured in T.Rodon or T.Commander. If this time elapses without your response, an emergency is triggered.

Battery level control

The T.Rodon operator can make your T.Flex instance send emergency warnings and battery alarms if the battery charge is below a certain level.

The notifications that the operator receives depend on the following parameters:

  • Battery Level Warning
    This parameter sets the value which is lower than normal but is not critical. If the battery level becomes lower than this, T.Flex sends out an emergency message with the subject "Battery level warning".
  • Battery Level Alarm
    This parameter sets the critical value. If the battery level falls below this, T.Flex sends out an emergency message with the subject "Battery level alarm".

Another battery control function is Battery Call. With this feature is enabled, if the battery level becomes critical, T.Flex starts an emergency call. This happens without a warning popup timer.

Battery Level and Battery Call can be enabled at the same time.

Emergency contact

The Emergency Contact feature includes two actions: emergency call by GSM and emergency SMS. The call and the SMS are triggered by any LWP emergency. The numbers for the call and the SMS are set by the administrator in T.Commander.

Emergency call by GSM and Emergency SMS can be enabled only from T.Rodon.

The emergency SMS includes information about the type of emergency and the coordinates of the lone worker.

Note:

When an emergency GSM call is made or an emergency SMS is sent, they are charged to the SIM card owner's account in accordance with the mobile operator’s charges.
