Emergency Maintenance (EM)
Though this maintenance is used with the same sense of that of breakdown maintenance, a little difference exists. The action in Emergency Maintenance is taken up immediately when the complaint is received where as the BDM will have a breathing time and is carried out after deciding the order of priority by some sequencing rules. This policy is applied in the emergency wards of a hospital, fire stations, police stations, underground mines, accident planning of an industry, etc.
When the nature of work in an organization is hazardous or the probability of occurrence of accidents is high, such a policy is adopted. A group of people will be kept for the purpose when this policy is adopted and will not be disturbed even if they are idle when there are no complaints.
