Information about the hazardous characteristics of the materials Information the performance capabilities of protective systems Heretofore unrecognized hazards Intentional changes to process materials, technology, equipment, procedures, and facilities are controlled by Section 9.9. 6.1.4 Sources of Data. 6.1.4.1 Data sources shall be identified and documented for each input data requirement that must be met using a source other than a design fire scenario, an assumption, or a building design specification. 6.1.4.2 The degree of conservatism reflected in such data shall be specified, and a justification for the sources shall be provided. 6.1.5* Maintenance of the Design Features. To continue meeting the performance goals and objectives of this standard, the design features required for each hazard area shall be maintained for the life of the facility subject to the management of change provisions of 9.9. A.6.1.5 As used in this section, maintenance includes the preventative maintenance required for the design features that are part of the performance-based design, as well as the requirement to maintain the design itself. 6.1.5.1* This shall include complying with originally documented design assumptions and specifications. A.6.1.5.1 Design features, including methods and means and administrative controls, should be included in preventative maintenance programs to ensure their continued operability. 6.1.5.2* Any variation from the design shall be acceptable to the authority having jurisdiction. A.6.1.5.2 This is not intended to prohibit future variations in the design features, but only that when modified these features are again subject to AHJ review. [SR No. 34] 6.2 Risk Component and Acceptability. (Reserved) The specified performance criteria of 6.3 and the specified fire and explosion scenarios of 6.4 shall be permitted to be modified by a documented risk assessment acceptable to the authority having jurisdiction. The final performance criteria, fire scenarios, and explosion scenarios for the performance-based design shall be documented. [SR No. 35, related to PC 440]
