Proactive maintenance is more of a preventive maintenance approach for the mechanical and electro–mechanical devices, electrical fixtures and fittings, and civil structures and compositions. In these, we have trained personnel to regularly inspect these for any damage, wear and tear, proper functioning and alignment. They do regular oiling and greasing for mechanical devices with moving parts. Each device or appliance or structure has a checklist to be followed for preventive maintenance and inspection. This checklist is thoroughly followed, and remedial actions are promptly taken wherever necessary. Remedial action may include replacement of the device or appliance to prevent further damage. This also involves installation, activation and maintenance of emergency alarm and response systems. These set of activities help to maintain and prolong the effective life of the electrical, mechanical, electro–mechanical appliances and devices, and civil structures.
