BSI set lone worker benchmarks

BSI's latest publication, BS 8484, is a Code of Practice for the provision of services based on lone worker devices. The electronic devices transmit a worker's location, identity and voice to a monitoring centre and requests assistance.

As well as laying out the minimum functionality for the device, BSI also prescribes the quality of the audio transmission - which it said is essential when assessing a situation, requesting the right response and to prevent false alarms. It also recommends the devices can be discreetly activated so there are no obvious signs of activation to an aggressor.

Other requirements are designed for alarm receiving centres which should operate 24/7 and have a continuity plan to operate from alternative premises within two hours. The centres should meet police criteria for the highest level response.
