form of maintenance particularly a variant of condition-based maintenance (CbM) and risk-based maintenance (RbM).
There are two key facets to EbM:
Fixed intervals that vary in length at different locations (such as
hallways carpets in high traffic areas done every week vs. low-traffic
areas done once a month)
2. Variable intervals or floating intervals to respond to certain events - no fixed amount of time
between scheduled maintenance activities but activities must follow (or
precede) certain events.
Listed below are some of the attributes of this maintenance paradigm:
Exposure-based maintenance is sometimes organized on a variable
interval or floating
interval. to capture changing exposure conditions such as inclement weather.
- The intervals of maintenance activities will vary in different locations (ie., "exposure zones").
frequency of maintenance typically depends on
environmental conditions, such as:
traffic or heavy traffic.
- Light Use vs. Heavy Use
Included below are some outline examples of exposure-based maintenance tasks:
roof after each
rainfall or inclement
generator after each power outage"
- We vacuum our stairwell carpets once a month since the traffic is lighter than in our hallways, which we vacuum once a week.
Evaluation and Management Principles
Exposure based maintenance is not suitable for bounded assets and some non-discretionary maintenance tasks.
