A closer view of PHIL 9550 showed these men wearing their headlamps outside the confines of a coal mine. Both were seated on a rail pull-car used to pull a string of coal bins, which would carry raw ore up, and out of the subterranean mine shafts. The man at right appeared to be an industrial hygienist, for he was carrying what appeared to be an air-quality measuring device (see PHIL 9550). The miner at left, was wearing protective knee pads, which he'd need when maneauvering around in a crouched position in the small spaces inside the mine shaft. The coal dust pattern on their faces showed that they hadn't been wearing protective breathing masks. Airborne coal dust in the small confines of a mine, made miners predisposed to the long-term negative health effects of this profession such as 'black lung disease', or 'coal-workers' pneumoconiosis' (CWP).
