Overview

The proper management of change (MOC) lies at the heart of any successful risk management or process safety management program. It can be taken for granted that everyone associated with the design and operation of any industrial facility wants to do a good job. Yet, in spite of their best intentions, accidents continue to happen; people get hurt, production is lost, and the environment is polluted. All of these undesired events are caused by uncontrolled change. Someone, somewhere moved operating conditions outside their safe range without taking the proper precautions, i.e., without implementing the MOC process.

Simply setting up an MOC system, with its accompanying forms and software, is not sufficient. The people who use the system must understand its intent and the manner in which it is to be used. A facility’s MOC program may look good on paper, but, if the people working there do not understand its fundamental purpose then that program will not be effective. MOC is not just a program — it is a way of life for all employees and contract workers.

There is, however, one note of caution that should be sounded. It has been stressed throughout this book that a key to a successful process safety program is to develop a culture that encourages the involvement of all employees. In this respect, an MOC program is different. The program imposes a clear structure and discipline on all employees and discourages spontaneous actions.

The effort needed to properly manage change can be substantial. It has been reported (Bradley, 1996) that the number of changes that flow through the MOC system is typically around 250 per year for a medium-sized site (with say 140 employees) and up to 1,000 a year for a large site with say 2,000 employees. One world-scale refinery in Texas had 1,400 changes in 2008. About 75% of the changes were regarded as moderate, i.e., they were not perceived as materially affecting the safety of the unit; nevertheless, they had to be handled through the MOC system.
