The 20-Year Safety Rule: Ensuring Long-Term Integrity in Industrial Systems

We are pleased to announce the publication of our latest technical feature in IWMA Insider Issue 6. This article addresses one of the most overlooked aspects of industrial maintenance: the critical 20-year safety rule for automated systems. As machinery stays in service longer, understanding the mathematical and physical limits of safety-related parts of control systems becomes essential for any responsible operator.

 
The piece explores the concept of “mission time,” explaining why most safety components—from relays to sensors—have a strictly defined lifespan. We delve into the technical reasons why, after two decades of operation, the statistical probability of a fail-to-danger scenario increases significantly. Our analysis highlights that even if a component appears to be functioning correctly, the underlying material fatigue and electronic degradation can compromise the entire safety integrity of the machine.

Furthermore, the article outlines the specific risks that arise after these twenty years of service, including legal liability, non-compliance with modern safety standards, and the high cost of unplanned downtime. By adopting a strategy of proactive replacement and modernization, companies can not only prevent catastrophic failures but also improve the overall operational efficiency and longevity of their assets.

Staying informed on these regulatory and technical boundaries is vital for maintaining a competitive edge in the wire and cable industry. We invite you to read the full analysis to understand how to better manage your equipment’s lifecycle and ensure a safe working environment for your team.
