• Description:
  The U.S. National Institute for Occupational Safety and Health (NIOSH) developed an active proximity warning system called hazardous area signaling and ranging device (HASARD) for warning workers as they approach known dangerous areas around heavy mining equipment and other dangerous work zones. HASARD is composed of a transmitter and a receiver. The transmitter generates a 60-kHz magnetic field using one or more wire loop antennas. Each antenna is adjusted to establish a magnetic field pattern for each hazardous area. The receiver, which is worn by the worker; is a magnetic field strength meter. The received signal is compared against preset levels that are calibrated to identify levels of danger: The receiver outputs can include visual, audible and vibratory indicators, and it can also be made to disable machine functions. HASARD was field tested on a Joy 12 continuous miner; a Komatsu 210 M Hauula and on a high wall launch vehicle. Slight modifications were made for each application. HASARD provided warnings as designed, and it proved to be rugged enough to withstand the harshest of production environments. [Description provided by NIOSH]
