Mine safety in coal mines, which in turn can initiate more extensive coal dust explosions. For this reason, rock dusts such as limestone dust are spread throughout coal mines to diminish the chances of coal dust explosions as well as to limit the extent of potential explosions, in a process known as rock dusting. Coal dust explosions can also begin independently of methane gas explosions. Frictional heat and sparks generated by mining equipment can ignite both methane gas and coal dust. For this reason, water is often used to cool rock-cutting sites. Miners utilize equipment strong enough to break through extremely hard
Rising Damp the dead, and I didn’t intend to be one of the latter!" Rising damp is a condition caused by ground moisture rising up a masonry wall by capillary action. It often occurs where there is no damp-proof course (DPC) or where the DPC has been damaged or bridged. Older houses, such as depicted in the show, were built without damp-proof courses or with a barrier material that is liable to failure. In the temperate/wet British climate, water infiltration into a house can be a problem, particularly in houses without a cellar or crawl space beneath them. The result of water
