Public sector workers are being offered increased on the job protection with the launch of a new personal tracking device designed to safeguard those who work alone or in vulnerable professions such as maintenance workers, social workers, nurses and carers.

The GPS device, known as the Bubble Tracker, uses satellite technology to locate the wearer’s exact position. This enables managers and colleagues to keep track of their whereabouts.

The BubbleTracker weighs 70g, is the size of a matchbox and can be stored in its belt-pocket for additional security. As well as being able to track the wearer’s location, the device is able to create a security fence which can send out an alert signal to a nominated computer, tablet or mobile phone if the wearer moves out of the pre-set zone. There is also an SOS panic button which enables the wearer to send for help if needed. Alerts can be sent via SMS message or email, and give the user’s precise location.

There are an estimated 3.5 million lone workers in the UK. According to the Lone Working Group, research shows that over 150 of these workers are attacked every day. The Health and Safety at Work Act provides that employers have a duty of care to ensure the safety and welfare of their employees when at work.
