Ylivuotorjunta

Ylivuotorjunta is a term used in Finnish industrial safety and reliability literature to describe the set of measures that prevent leakage from process equipment under abnormal conditions such as overpressure, overheating, or equipment failure. The concept emphasizes containment and the protection of people, environment, and assets by reducing the likelihood and consequences of leaks.

The scope of ylivuotorjunta includes design, detection, and response. Design elements aim to improve containment through robust seals and joints, secondary containment, and redundancy in critical components. Detection involves leak monitoring, pressure and temperature sensors, and acoustic or gas-detection systems. Automated responses include isolation valves, pressure relief devices, and emergency shutdown procedures to minimize leakage when abnormal conditions are detected. Maintenance and inspection practices—such as regular testing, gasket replacement, and corrosion monitoring—support ongoing effectiveness.

Applications span sectors with hazardous or valuable contents, including chemical processing, oil and gas, power generation, pharmaceutical manufacturing, and building services like water and HVAC systems. In these contexts ylivuotorjunta is integrated into broader process safety management programs and life-cycle approaches to risk.

Regulatory and standards context: organizations implement ylivuotorjunta within safety frameworks guided by national regulations and international standards for containment, leak detection, and safe shutdown. Effective practice relies on risk assessment, redundancy, and reliable monitoring and maintenance. If you’d like, I can tailor the article to a specific industry or standard.
