This is a detailed guide to the best practices and general standard principles regarding safe process isolation in all processing and production industries. It describes how to carry out process isolation in a completely safe manner without unplanned loss of containment which has the potential to damage personnel the environment and process plant equipment. It has general applications in all industries where process fluid is transported from energy-defined industries through manufacturing companies to servicing firms.You'll gain an overview of valve standard specifications permit-to-work systems and LOTO standards. Did you know that maintenance personnel must never perform a job that's not on the permit to work/toolbox form regardless of the persuasion of the operation personnel? This course will also serve as an introduction to fresh graduates and undergraduates alike to help bridge the industrial/technical knowledge gap and equip them for an impactful career as a process personnel.Did you know that positive isolation is quite different from isolation by valves? Did you know that ball valves are the most preferred valves for isolation by valves? This course is intended to help process engineers operators and technicians to consciously develop evaluate and improve their isolation procedures. The standards and practices contained herein are international standards culled from the UK SHE Total Energies BP ConocoPhillips Notore Chemical Industries Unified Alloys and Center for Chemical Process Safety (CCPS).
