In management of change

Modified facilities meet the requirements contained in management of change.

Control of Plant and Process Modifications Many accidents have occurred because plant or process modifications had unforeseen and unsafe side effects (Sanders, Management of Change in Chemical Plants Learning from Ca.se Histories, Butterworth-Heinemann, 1993). No such modifications shoiild therefore be made until they have been authorized by a professionally quahfied person who has made a systematic attempt to identify and assess the consequences of the proposal, by hazard and operability study or a similar technique. When the modification is complete, the person who authorized it... 

Use chemical interaction matrices to identify potential incompatibilities between combinations of materials (not just binary reactions) and interactions with cleaning solvents, heat transfer fluids and other utilities, equipment lubricants, scrubbing media, materials of construction, etc. Implement management of change procedures for changes in design, operation, equipment and chemistry.

It is incumbent upon the toller to develop and follow internal management systems as appropriate to support business needs, production needs, process safety, environmental responsibility, and worker health. The selection process should have considered whether or not satisfactory systems are in place. Nevertheless, the contract or auxiliary documents may be the vehicle used to help ensure that the system reviewed is the system actually used for completing the toll in question. Within the process safety management system, the management of change and training elements are essential subsystems. 

The review and approval process for procedures for the toll needs to be clearly understood between the toller and their client. This can be addressed in the management of change system. A preliminary process or batch procedure may be written or proposed as part of the toller selection process or may be included in the initial... 

Whether or not a toller site or a specific ongoing toll process is covered under a regulatory mandate to manage changes, there is always a question of when to involve the client in day-to-day management of change (MOC) activities. 

Management of change A system to identify, review and approve all modifications to equipment, procedures, raw materials and processing conditions, other than replacement in kind, prior to implementation. 

A primary objective of any safety program is to maintain or reduce the level of risk in the process. The design basis, especially inherently safer features that are built into the installation, must be documented. Management of change programs must preserve and keep the base record current and protect against elimination of inherently safer features. For identical substitution, the level of risk in the process is... 

Many maintenance risks are related to unclear and unsafe procedures. See Chapter 6. Additional information regarding management of change can be found in Chapter 7 of the CCPS Guidelines for Technical Management of Chemical Process Safety (CCPS, 1989b).
