- Use of improper materials of construction, during both initial installation and subsequent maintenance of operating facilities, can have catastrophic consequences. To assure that appropriate materials are used, a facility should adopt piping and vessel standards that are appropriate to the hazards present. Responsibility for the adoption of vessel and piping standards should be clearly designated. In many cases, available industry standards can be adopted; however, the process safety management system should address the organizational issue of who will identify the standards to be followed, who will monitor changes in the industry standards used, and who will communicate these standards and changes within the firm, vessel and piping specifications should be supplemented by systems to assure that the materials actually installed are the correct ones.
- When severity of risks is high, it may also be appropriate to adopt a tracking system-especially one for tracking materials of construction from the mills until the pipe, vessel, or other component is installed in the facility. A material tracking program can serve a control function in the process safety management system. Implementation of an effective material tracking program requires a considerable amount of planning, as well as an evaluation of potential suppliers who are willing to provide the necessary documentation with the finished products. At the plant level, considerable planning need to be expended in establishing a materials tracking program for some higher risk operations, while using more conventional methods for other operations. One effective mechanism is to establish separate accounts for ordering materials under the materials tracking program. Thus when an order is received by a pre-approved supplier, it is clear that special documentation requirement will be followed.
