A flame-trigger device was developed for use with barriers to suppress coal dust explosions in underground mines. Principal feature of the device is a dual infrared flame sensor combined with a pressure-arming element. This combination prevents false and premature triggering of the barrier. With minor modifications, the device can also be used with barriers for protection in other facilities against gas explosions and explosions involving dusts other than coal.
