Some miners unknowingly venture beyond the last row of roof bolts in an underground coal mine. The new permissible-type, intrinsically safe design modules described here represent an engineering intervention strategy toward improving miners' ability to recognize and avoid the hazardous zone of unsupported mine roof. These devices are designed to improve the miner's recognition of the unsupported roof by marking the end of roof support with a flashing red light and a written message warning miners to avoid the unsupported are ahead.
