  • device feedback testing and research conducted at underground facilities showed that a helmet brim-mounted light coupled with an auditory buzzer were best at getting the attention of a miner while they perform their work.
  • a "Smart Helmet" was developed.
  • the first approach is a helmet with fully integrated sensing, feedback, and communication hardware.
  • the helmet has an onboard, rechargeable battery to power the head lamp and the electrical components, including but not limited to, environmental sensors, location tracking hardware, and/or communications equipment. Since the electrical components are embedded, they are not easily discernible from a distance, thereby providing a safety helmet with similar appearance to current standard safety helmets. Such embodiments may be preferred in situations where aesthetic features are important for adoption of a safety helmet for industrial operations.
  • the second approach is to augment existing helmets by attaching electrical components, including but not limited to sensing, feedback, and/or communications hardware as independent modules.
  • One advantage of this approach is that it accommodates a greater number and variety of helmets, since the hardware modules can be designed with less specificity and hence applicable to a large variety of industrial helmets. Similar to the first approach, a removable, rechargeable battery is used to power the hardware modules.
  • One benefit of the second approach is that a greater degree of customization is possible. For example, environmental sensors could be added along with, for example, health monitoring sensors. This allows for improved monitoring and control for specific mine needs. For example, no lights are required in open pit mines, but a GPS & 3G/LTE SIM card could be added for location tracking and communications. As well, this approach creates an opportunity to design safety devices which can augment the capabilities of existing helmets which are already certified, approved, and in distribution and use.
  • any modifications to a hard hat or miner safety helmets should not make a mine worker less safe.

  • adding in additional electrical components which track the mine worker's location, monitor the environment, monitor the health status of the mine worker, and/or allow for communication with a control center more efficient significantly improves mine worker safety.
  • a user-facing camera and/or an onboard accelerometer and gyroscope will further assist mine operators and control centers, for example, to determine if a mine worker is working safely even if the mine worker is unable to or has forgotten to report in.
  • safety devices for a mine worker helmet are described, application of the safety devices is not limited to mine workers but instead are also applicable to other industrial helmets.
