In relation to fire safety it is particularly important to ensure that moving parts of machinery are subject to planned prevent he maintenance to prevent the equipment being a source of ignition.
If a rotating or moving part is not suitably lubricated in line the manufacturers guidance the machine may be liable to dry out (running dry) causing excessive friction. This in turn, creates a source of heat. This source of heat, if added to the potential for it to come into contact with contaminated lubricant, can increase the potential for a fire, as was the case at Kings Cross Underground station where a serious fire started in the escalator.
