Wearable Safety Technology
Sensor-equipped devices worn by jobsite workers, such as a vest or hard hat insert that detects a fall or a worker entering a hazardous zone, or a proximity sensor that alerts both a worker and equipment operator when they get too close to each other, feeding real-time safety alerts rather than relying solely on visual awareness.
Why it matters
Wearable technology works alongside, not instead of, a jobsite's existing safety program and PPE requirements, a proximity sensor alerting an equipment operator doesn't replace the spotter and exclusion zone procedures already required around heavy equipment, so it's an added layer of protection rather than a substitute for established practices.
On a real project
A highway contractor equips workers near active equipment with proximity-sensing wearables that alert both the worker and the equipment operator with an audible warning when they come within a set distance of each other, layered on top of the crew's existing spotter procedures.
Who this matters most to
A Safety Manager evaluates and rolls out wearable safety technology, monitoring the data it generates for patterns, such as a specific area of the site triggering frequent proximity alerts.
Where this goes wrong
A project equips its crew with fall-detection wearables and assumes the technology itself reduces fall risk, cutting back on its usual fall protection inspections since the wearables provide a safety net. A worker falls from height wearing a device that alerts responders quickly after the fact, but the underlying missing guardrail that caused the fall was never actually caught because the routine inspection it would have been found in had been scaled back.
