res, malfunctions, deficiencies, deviations, defective components, uncontrolled combustible material and nonconformances, are promptly identified, reported, and corrected. i. Records Records should be prepared and maintained to furnish evidence that the criteria enumerated above are being met for activities affecting the fire protection program. j. Audits Audits should be conducted and documented to verify compliance with the fire protection program, including design and procurement documents, instructions, procedures and drawings, and inspection and test activities. 5. General Plant Guidelines a. Building Design (1) Fire barriers with a minimum fire resistance rating of 3 hours should be provided to: (a) Separate safety-related systems from any potential fires in nonsafety-related areas that could affect their ability to perform their safety function; 9.5.1-35 DRAFT Rev. 4 - April 1996 (b) Separate redundant divisions or trains of safety-related systems from each other so that both are not subject to damage from a single fire; (c) Separate individual units on a multiple-unit site unless the requirements of General Design Criterion 5 are met with respect to fires. Where fire area boundaries are not wall-to-wall, floor-to-ceiling barriers with all penetrations sealed to the fire rating required of the boundaries, an evaluation must be performed to assess the adequacy of fire boundaries to determine if the boundaries will withstand the hazards associated with the area.115 (2) Appropriate fire barriers should be provided within a single safety division to separate components that present a fire hazard to other safety-related components or high concentrations of safety-related cables within that division. (3) Openings through fire barriers for pipe, conduit, and cable trays which separate fire areas should be sealed or closed to provide a fire resistance rating at least equal to that required of the barrier itself. Openings inside conduit larger than 10 cm (4 inches) in
