Figure 67.-Whitewashed band on wide rib or brake side of main haulage road. Miners trying to avoid an approaching trip or avoid the trolley wire will instinctively take the banded or safest side. Manholes and switch holes are in rib having band. Snapper knows it as the brake side. Boss: Whitewash all manholes and switch holes, and whitewash band on rib on wide rib side. Using whitewash makes mine lighter and more sanitary. It may prevent accident.
