Many of the publications that we offer are to do with the topic of Process Safety Management (PSM), or with related topics such as the offshore Safety and Environmental Management System (SEMS) and Safety Cases. An overview of the topic of Process Safety Management is provided here. Much more detail is available in the books Process Risk and Reliability Management and Offshore Safety Management.

This analysis do with the catastrophic incident at the Fukushima-Daiichi nuclear power plant was first published as an article at this site in the year 2017. The event itself took place on March 11^th 2011. At first it was headline news. Then publicity to do with what happened receded into the background and new crises came to the fore, and captured our imaginations.

This Safety Moment provides an initial overview of the topic of Fault Tree Analysis (FTA). The technique is described in detail in the book Process Risk and Reliability Management.

Risk Analysis

Risk can be analyzed in one of two basic ways: inductively or deductively, that is either bottom-up or top-down.

Lockout / tagout systems are routinely used to protect workers when they are working with or close to hazardous systems. They are typically used in conjunction with the other isolation methods. Once a switch or valve is in the correct position it is locked so that it cannot be moved, and a 'Do Not Operate' tag is attached to it. (Valves are often chained in place, with the lock being used to secure the chain such that the valve handle cannot be moved.)

When developing the layout for a facility it is very important to ensure that personnel can move around quickly and safely using stairways, ladders, platforms and ramps. They should also be able to use the stairways and ladders to move maintenance equipment and tools, as needed and also to evacuate the facility during an emergency.

Risk

This article discusses risk fundamentals in the process and energy industries.The word 'risk' has a wide range of meanings. In the context of process plant management it can be categorized in one of three ways.
