This interactive online course identifies common causes of equipment failures and the steps involved with prioritizing the failure events and conducting failure investigations. The learner will be introduced to several investigative analysis tools used to forensically exam the failure and the importance of maintaining equipment histories.

Learning Objectives

  • List common causes of equipment failures
  • Describe investigative analysis tools
  • Recall the importance of equipment histories
  • Identify failure events
  • List common steps to conduct a failure investigation

Key Questions

The following key questions are answered in this module:

What are some reasons why equipment is used for tasks it is not designed for?
Equipment is often used for tasks it was not designed for as a result of financial challenges, lack of available resources, no understanding of the equipment's true capability, and laziness.

What is condition monitoring?
Condition monitoring is the process of observing the operation of equipment and measuring important parameters associated with its use, such as temperature or vibration.

What is included in an equipment inspection?
An inspection may include taking readings on equipment temperatures, pressures, or vibrations, or it may be a sensory inspection, looking, listening, and touching the equipment.

What is root cause analysis?
Root cause analysis is the name given to processes and methods for identifying the causes of failures. These can be process, safety, production or equipment failures.

What are the three most common root cause analysis methods?
Three of the most common are the Five Why, Fishbone Diagram, and Fault or Logic Tree Analysis.

Sample Video Transcript

Below is a transcript of the video sample provided for this module:

Not all equipment failures require investigation. In some cases, the cause of an equipment failure may be quite obvious. Such is the case with damage from weather-related events such as floods or tornadoes, intentional sabotage, or automobile accidents. In other cases, the equipment is not crucial to the process or it can easily be replaced with little cost or impact to production. Failure investigations are most useful when high-dollar, critical equipment fails unexpectedly and for an unknown reason. Investigative techniques vary based on the industry, environment, equipment type, and level of failure. Regardless of the investigative methodology and specific steps involved, all investigations should take a forensic approach to identifying the cause or causes of the failure. This means carefully examining the scene and looking for evidence that can provide clues into the nature and possible cause of the failure. Interviewing witnesses provides a first-hand account of how the equipment was running or what occurred as the equipment failed. It is important to document the facts and not the opinion of the workers involved. Use photos, videos, sketches, and diagrams to clearly identify the “as found” condition of the equipment. If appropriate, collect samples of process fluids, lubricants, damaged gaskets, seals, piping, and fittings. Preserve damaged equipment components so they can be analyzed. The investigator must avoid jumping to conclusions. A systematic review of the failure and evidence will ultimately identify the root causes, or reasons, for equipment failure.
