Basics of Preventive Maintenance - Identifying Critical Equipment

Establishing focus on the Critical Few 


While Preventive Maintenance should ideally be undertaken for all Equipment, the ZED Framework places high importance on Preventive Maintenance of "Critical Equipment". 

 Three Parameters give higher score for attention to Critical Equipment

  • Planned Maintenance (of Operational Equipment & utilities); 
  • Planned Maintenance of Energy Control Systems; and 
  • Planned maintenance of Environment effect control machines. 


 This article intends helping organizations in identifying their Critical Equipment by carrying out a systematic assessment on key aspects. The assessment takes into account two aspects of every Equipment
  • Impact of equipment Breakdown or Fault on Environment or Safety 
  • Impact of equipment Breakdown or Fault on Operations.

 Any Equipment which can impact the Environment or lead to a Major Injury in case of a breakdown are classified as critical - even if they have no impact on Operations.


 Breakdowns that have limited Environmental Impact (i.e. Work Area only) or Limited Safety impact (Minor Injury possible) should be evaluated for Impact on Operations as well as probability of occurrence. Basis this they can be considered as critical or non critical.
 

To help you determine Critical Equipment you can use the worksheet created by me or locate other sources. However at the end of this exercise you should have a list of all Equipments with a classification - Critical / Non Critical and put in place Preventive Maintenance Plans for them as well as ensure adherence & measure effectiveness (MTTR/MTBF).
