Campus Utilities Mission
Subject to capital and operating cost constraints (enterprise mentality)
• Establish & maintain plant, infrastructure and services for a safe, healthy, and productive campus environment• Maintain services to on-campus residence community• Support special requirements of funded research• Meet medical and patient care environmental standards

Preparedness• A set of contingency plans or
processes that enable ongoing operation of utilities through unplanned system disruption
• Internal• External• Forces of Nature

Murphy’s Law
Everything that can fail, shall fail
• What could go wrong with the system or process?
• How badly might it go wrong?
• What needs to be done to prevent (or accommodate) failures
![Page 27: Preparedness Planning Campus Utility System RMA Webinar Feb 28, 2013.](https://reader036.fdocuments.net/reader036/viewer/2022062619/5516f142550346f5558b4ae9/html5/thumbnails/27.jpg)
27
Failure Mode and Effects Analysis
• FMEA : a systematic analysis of the system to whatever level of detail required to demonstrate that no single failure will cause an undesired event
![Page 28: Preparedness Planning Campus Utility System RMA Webinar Feb 28, 2013.](https://reader036.fdocuments.net/reader036/viewer/2022062619/5516f142550346f5558b4ae9/html5/thumbnails/28.jpg)
28
Failure Mode and Effect Analysis Simple Approach
• Risk Priority Number• Severity x Occurrence x Detection =
RPN– Severity
• Rates the severity of the potential effect of the failure.– Occurrence
• Rates the likelihood that the failure will occur.– Detection
• Rates the likelihood that the problem will be detected before it reaches the end-user/customer.
– RPN rating scales range from 1 to 5 or from 1 to 10, with the higher number representing the higher seriousness or risk.
![Page 29: Preparedness Planning Campus Utility System RMA Webinar Feb 28, 2013.](https://reader036.fdocuments.net/reader036/viewer/2022062619/5516f142550346f5558b4ae9/html5/thumbnails/29.jpg)
RPN Considerations
• Rating scale example:– Severity = 10 indicates that the effect is very
serious and is “worse” than Severity = 1.
– Occurrence = 10 indicates that the likelihood of occurrence is very high and is “worse” than Occurrence = 1.
– Detection = 10 indicates that the failure is not likely to be detected before it reaches the end user and is “worse” than Detection = 1.
