The document provides a case study and analysis of a fatal explosion that occurred at a Total Petrochemicals site in Carling, France in July 2009. The explosion occurred during the restart of a furnace after a shutdown and killed two operators. A judicial investigation found that Total had bypassed or disabled multiple safety systems on the furnace, including the burner safety locks and general safety interlocks. They also did not follow proper startup procedures. The root causes were found to be organizational factors like deficient process safety management and a lack of respect for operating procedures, as well as technical deficiencies in the furnace design and multiple human errors.
This flow chart outlines the risk management process for ensuring asset integrity. It involves identifying asset groups, performing a criticality assessment, developing inspection and maintenance plans, conducting inspections and repairs during turnarounds, implementing risk-based inspections and residual life assessments, and closing the loop with process monitoring, learnings, and training to continuously improve integrity.
This document provides an overview of non-destructive testing (NDT) techniques, with a focus on magnetic particle inspection (MPI). It begins with introductions to NDT and MPI, explaining how MPI uses magnetic fields and particles to detect surface or subsurface defects in ferromagnetic materials. The document then covers MPI principles, materials' interactions with magnetic fields, testing procedures, advantages, and limitations. Examples of MPI indications for cracks in different components are also shown.

This document discusses non-destructive testing techniques, specifically magnetic particle inspection. It begins by defining non-destructive testing and why it is used. Then it discusses the principles and procedures of magnetic particle inspection including magnetizing materials, applying magnetic particles, and demagnetizing after inspection. The document provides examples of industries that use magnetic particle inspection and its limitations in detecting certain defect orientations.
This document discusses various non-destructive testing (NDT) methods, including:
1. Visual testing using tools like borescopes and videos for inspection.
2. Magnetic particle inspection which uses magnetic fields and particles to detect surface and subsurface discontinuities in ferromagnetic materials.
3. Liquid penetrant testing which uses penetrant liquids and developers to detect surface discontinuities in both ferromagnetic and non-ferromagnetic materials.

monte , il faut savoir rester soudés , pour
mieux résister aux épreuves » …
une devise de la vie, de ses contraintes et risques ,
par analogie à l’inspection/sureté en Pétrochimie ,
(i.e. directive CE pression et le savoir rester soudés

corollaires :
« surtout après avoir été roulés », notamment par
les « serial cost killers », une race inextinguible qui
ne cessera de mettre pression , fièvre et stress , sur
nous et la sureté des usines … , en plus des Cnd , il
nous faut donc aussi soupape de sureté ,résilience et
relaxation , pour surmonter les épreuves …
