World’s smallest lone worker device gains accreditation from Secured by Design

Peoplesafe’s MicroSOS, the world’s smallest and lightest lone worker device, has been accredited by Secured by Design (SBD), achieving the prestigious SBD Police Preferred Specification standard.

Exclusively developed by Peoplesafe to assist lone workers and those at risk in an emergency, the innovative MicroSOS is the world’s smallest and lightest lone worker device is fully certified, complying with BS 8484:2016, and is IP67 rated, which means it’s fully protected against dust and is waterproof.

Launched last month at the Safety & Health Expo in London, MicroSOS represents the next generation in lone worker protection. The tiny unit has the appearance of a USB stick, making it ideal for getting help discreetly. With just one button press the device links up to Peoplesafe’s Alarm Receiving Centre which is able to provide assistance 24/7 via a skilled team of Controllers who have a priority Police response at their disposal if necessary.

Even if a user is not able to press the SOS button manually, the device also has an optional ‘man down’ sensor which can automatically activate the alarm should a user fall and become incapacitated.

The MicroSOS has been designed to be worn in a number of different ways for convenience and discreetness. It also comes with a magnetic docking station allowing it to be easily charged.

Secured by Design Development Officer Lyn Poole said: “It’s great to be able to add the MicroSOS from Peoplesafe to their SBD accredited products.

“I like the fact that the MicroSOS is small enough to conceal in a hand, clip to a waist band, or attach to a specially adapted ID holder. It is ideal for personnel that need to have it easily accessible and hidden. It is easy to use and fuss free.”

Peoplesafe Marketing Director Will Murray said: “We are delighted to receive Secured by Design accreditation as part of the launch of MicroSOS.

“It’s predecessor - the MicroGuard is also accredited, delivering effective help to thousands of vulnerable people, whilst being convenient to carry and easy to use. The MicroSOS incorporates more features and cutting-edge technology, packed into an even smaller and simpler design.

“The MicroSOS is the pinnacle of years of industry experience and product development, representing the next generation of personal safety alarms.”
