And alternating-current motors of the slip ring type when running usually give off electric arcs or ashes that will ignite fire damp. Other motors that have no moving electric contacts may become dangerous through accident, deterioration, or neglect. Auxiliary apparatus such as fuses, switches, rheostats, and controllers may arc, ash, or become heated to such a degree that fire damp can be ignited. Such equipment is still more dangerous when worn or out of repair. In the United States the development of apparatus for use in gaseous mines has been associated largely with coal-cutting equip ment run by electricity. This is undoubtedly due to the use of such equipment at the face of the mine workings, where the chance of igniting fire clamp is necessarily greatest. One American manu facturer built a coal-cutting equipment of the totally inclosed type for use in fire damp atmospheres in 1903. Another built similar equipment with special protective devices in 1906, for export. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
