The Machinery Design engineer’s goal is to make the design robust so that equipment controls are not required. Remember, the Equipment Design engineer CANNOT rely on machinery controls or control plans to overcome potential weaknesses.
Emphasis should be placed upon design actions aimed at preventing or reducing the severity of the efforts of failure modes, or preventing or reducing the occurrence of causes. Detection does not decrease criticality.
In order to track and follow up design actions, it may be helpful to assign a number to them. If no actions are recommended, it is desirable to enter “No action at this time” in the column. This prevents someone interpreting a blank space as an oversight or an incomplete resolution.
List the actions that can be taken to prevent or reduce the occurrence of the causes of a failure mode, or to detect the failure mode. Enter a design action. If no actions are recommended, then enter “No action at this time.”
