Electrical equipment in hazardous areas the participation of operations, maintenance, safety, electrical and instrumentation professionals, the use of process diagrams and material flows, MSDS and any pertinent documents, information and knowledge to determine the hazards and their extent and the countermeasures to be employed. Area classification documentations are reviewed and updated to reflect process changes. Soon after the introduction of electric power into coal mines, it was discovered that lethal explosions could be initiated by electrical equipment such as lighting, signals, or motors. The hazard of fire damp or methane accumulation in mines was well known by the time electricity was introduced, along with the
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
