Mechanical Integrity

Maintaining the mechanical integrity of process equipment is important to ensure that it is designed and installed correctly, and operates properly. The mechanical integrity requirements of a PSM program apply to the following process equipment:

• Pressure vessels and storage tanks
• Piping systems (including piping components, such as valves)
• Relief and vent systems and devices
• Emergency shutdown systems
• Controls (including monitoring devices and sensors, alarms, and interlocks)
• Pumps

The employer must establish and implement written procedures to maintain the ongoing integrity of process equipment. Employees involved in maintaining the ongoing integrity of process equipment must be trained in an overview of that process and its hazards, and in the procedures applicable to employee job tasks.
