Construction and equipment meet the designed specifications

Construction and equipment meet the design specifications. Obtaining field verification or performing document review for the new or modified process can validate design specifications for construction and equipment. If a change is not physical (such as a setpoint for an interlock shutdown), the method for the change and its anticipated effects should be reviewed. 

Pre-Start-up Safety Review. A safety review is mandated for new facilities and significantly modified work sites to confirm that the construction and equipment of a prcx ess are in accordance with design specifications to assure that adequate safety, operating, maintenance, and emergency procedures are in place and to assure pr(x ess operator training has been completed. Also, for new facilities, the PHA must be performed and recommendations resolved and implemented before start up. Modified facilities must meet management of change requirement. 

A specification that identifies the basis on which a particular surface finish is selected will help the manufacturer to determine the appropriate construction, and provide some guidance on the method by which it is attained. Perhaps of equal importance, it will focus attention on details of the equipment design that are important to secure the objectives sought by the specification of a particular surface finish. The function of the designer is to match these attributes with other performance-related features of the equipment, and from these directions produce a blend of mechanical and geometric construction with a surface finish that meets the full requirements of the installation.
