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
Damp (structural) damp proofing creams and these have become the most popular type of rising damp treatment. This replaces a draft BBA guidance note that said Damp-proofing creams differ from fluid-based damp-proofing treatments in a number of ways: In his book, Dampness in Buildings, Alan Oliver refers to research carried out in Belgium regarding the effectiveness of different types of rising damp treatments: Replastering will often be carried out as part of a rising damp treatment. Where plaster has become severely damaged by ground salts there is little argument about the need to replaster. However, there is considerable debate about: BS6576:2005 states
