A lone worker device suited to an industrial site is a wearable that can raise an alarm in three ways, through a manual SOS button, an automatic man-down or no-motion alarm, and a missed check-in, and that reports where the worker is indoors as well as outdoors. GPS alone does not locate someone inside a warehouse, so sites with indoor work need a device that uses an indoor positioning network. Coverage across the whole site, battery life over a full shift and a tested response procedure matter more than the brand, because an alarm only helps if someone receives it and can reach the worker quickly.
The full guide is Lone worker safety, which covers who counts as a lone worker and the monitoring options. When comparing devices, test signal coverage in cold stores, mezzanines and yards before purchase, since dead zones are often where isolated work happens. Check how alarms escalate, to a supervisor’s phone, a control room or a monitoring service, and what happens when the first person does not answer. Where a site already runs forklift proximity tags, some tags combine both roles, which reduces the number of devices a worker carries. The employee safety devices guide compares wearable types, and suppliers are listed in the directory.
