文档介绍：PURPOSE
The purpose of Management of Change (MOC) is to detect and manage changes to the facility either in technology, design, operation, new materials, equipment or maintenance. These changes have the potential to introduce hazards into the facility. The MOC process detects the change, evaluates the hazards, manages the mitigation of the hazards, and controls the integration of the change into the facility. The purpose of this element is to manage all changes, other than "Replacement in Kind" prior to implementation of the change.
This Management of Change policy is pliance with the OSHA – Process Safety Management (PSM), 29CFR 1910-119(l) and the EPA Process Safety Management, 40CFR 68 Section 112r requirements.
DEFINITION OF CHANGE
A “Change” is anything that is not a “Replacement in Kind”. “Replacement in Kind” for purposes of this policy is defined as the replacement with identical or same metallurgy, design and normal operating conditions, operating and maintenance procedures. Changes fall into the following five categories:
A. Technology
B. Facility
C. Equipment
D. Procedure
E. Raw Material
A. CHANGES IN TECHNOLOGY
Changes in technology arise whenever the technical basis for design and operation of the plant (., the design/actual capacities, process chemistry, mechanical design, process control hardware/software, and instrumentation) is altered. Examples of these types of changes are:
1. Non-routine changes to instrumentation, control loops, puter programs, such as changing the range of transmitters or control valve failure position;
2. Any change in safety alarm settings, interlocks, and process trips. These can include changes in alarms, instrumentation and control schemes;
3. Projects to increase facility throughput or modate different feedstocks or products;
4. Changes in operating conditions including pressures, temperatures, flow rates, equipment operating speeds, or process conditions outside of the normal operating maximu
