Warning System for Mobile Machinery Hazardous Zones

This invention relates to a warning system designed to protect individuals working near hazardous machinery. The system consists of a proximity-warning transmitter mounted to hazardous machinery and a receiver, worn by a worker, capable of detecting the transmitter signal. This worker-safety system can incorporate visual alerts and audible alerts. It also allows automatic shutdown of machinery upon receiver activation and may be particularly useful in the mining industry.

Potential Commercial Applications: Competitive Advantages:
  • Auxiliary safety equipment for heavy machinery
  • Occupational health and safety
  • Mining worker safety
  • Easy transmitter installation
  • Signal can be adjusted for an audio or visual "warning zone alert" and a proximal "imminent danger zone alert"

Development Stage:
  • In situ data available (on-site)
  • Prototype
