Heron, Peter M., Accidents Caused by Plant Modifications, Loss Prevention 10, American Institute of Chemical Engineers, New York pp. 72—78. 

In one paper, Peter Heron described the approach that BP Chemicals International, Ltd. London used at that time. He pointed out that all process and plant changes were subjected to a regime of formal scrutiny and authorization. Minor alterations such as the addition of a valve, a change in materials of construction, or the switch in the type of mechanical seal were made at the discretion of the group manager, or the supervisory level above the unit supervisor.

Peter Heron s article concludes with a statement that all of these procedures bring together a multidisciplined team that ensures fewer problems in implementing, commissioning, and operating modified units. He further reflects that there is often a dilution of experience in management and these procedures assist in ensuring consideration of a broad spectrum of potential side effects. [17]...
