During a review of non-compliances with Ap … During a review of non-compliances with Appendix R that are being resolved as part of the NFPA 805, Risk Informed Fire Protection Transition, it was identified that a non-compliant operator manual action to manually backwash the cooling water strainers was identified in several fire areas, but the need to manually backwash the strainers may be required in other fire areas not previously identified. For Fire Areas 25, 30, 31, 38, 66, 109, and 117 power to the cooling water strainer central control panel could be affected which could require the need to perform a manual backwash of the strainers.
