What are Critical Spares?

Critical spares are recognized as components that are likely to fail and whose failure can significantly impact the system's operations or production. Identifying these components involves analyzing the failure modes and effects, allowing organizations to prioritize which spare parts are crucial to keep on hand. By focusing on items that are prone to failure, businesses can better manage their maintenance strategies and minimize downtime. This proactive approach ensures that when a critical component fails, the necessary spare is readily available to facilitate quick repairs and maintain operational continuity, aligning with reliability-centered maintenance principles.

Other options do not accurately capture the definition of critical spares. For instance, declaring items as having "no risk of failure" contradicts the fundamental premise of critical spares, as these are precisely the items that have an associated failure risk. Also, while it may be advantageous for spares to be easy to source, this alone does not qualify them as critical unless they are related to significant failure risks. Lastly, including all maintenance items in the storeroom overlooks the specificity required to categorize critical spares, as not all maintenance items have the same level of importance in terms of operational reliability.
