Maintenance Practices for Plant and Equipment...

Maintenance Practices for Plant and Equipment Nothing lasts forever and all the equipment in a plant has associated with it some predefined life expectancy or operational life. Maintenance is the work of keeping the plant and equipment in good condition for operation. It is the action taken to prevent plant and equipment from failing and to repair normal degradation experienced with the operation and to keep it fit for operation. Some organizations do not expend the necessary resources to maintain equipment in proper working order. Instead they wait for equipment failure to occur and then take whatever actions are necessary to repair or replace the equipment. However this fact is to be kept in mind that if there is failure in performing maintenance activities intended by the equipment designer, the life of the operating equipment gets shortened. Adequate maintenance of plant and equipment is necessary to ensure that the plant and equipment is working reliably and effectively. Maintenance can be part of a planned programme or may have to be carried out at short notice after a breakdown. It is carried out to prevent equipment problems and to put fault right. It always involves non-routine activities and can expose those involved and others as well to a range of risks. An effective maintenance programme can result into more reliable plant and equipment. Fewer breakdowns will mean less dangerous contact with machinery is required. It also results into cost benefits because of better productivity and efficiency. Additional hazards can occur when machinery becomes unreliable and develops faults. Maintenance allows these faults to be diagnosed early to manage any risks. However, maintenance needs to be correctly planned and carried out. Unsafe maintenance can cause accidents and serious injuries either during the maintenance or to those using...
