Decommissioning a pressure vessel under API-510 involves a thorough cleaning to remove hazardous substances, a final inspection to document the vessel's condition, and ensuring all environmental regulations are met during disposal. The vessel may need to be dismantled in a controlled manner, especially if it contained toxic or radioactive substances. Documentation of the decommissioning process is crucial for compliance and environmental protection.

API-510 requires that pressure vessel inspectors undergo rigorous initial training, which includes both theoretical and practical components. Inspectors must understand the principles of pressure vessel design, the properties of materials used, and the dynamics of pressure systems.
Continuous education is also mandated, requiring inspectors to attend workshops, seminars, and refresher courses regularly to stay updated with the latest changes in regulations, inspection technologies, and best practices. This ongoing training ensures that inspectors maintain a high standard of expertise and are well-equipped to enforce safety and compliance effectively.
