firefighting and safe shutdown operations. g. Capability to maintain habitability of areas occupied or traversed by plant operations staff in performing safe shutdown operations, including the control room and post-fire safe shutdown system and component locations (and egress/access thereto) where local operator actions may be necessary. Additional guidelines and standards applicable to the review of ventilation systems are provided or identified in Regulatory Guide 1.189. 7.1.6 Drainage Revision 4 - October 2003 29 The design of plant floor drains should be reviewed to assess the capability to protect equipment important to safety from flooding associated with automatic and manual fire suppression, including inadvertent operation or failure of fire suppression systems. Drains may also impact concentrations of gaseous suppression agents in total flooding systems. Drainage in areas containing flammable or combustible liquids should be designed to minimize the potential to propagate fire to other areas via the drainage system. The drainage system capability to control and contain potentially contaminated water should also be described in the fire hazards analysis and/or fire response procedures. Additional guidelines are provided in Regulatory Guide 1.189. 7.1.7 Emergency Lighting Emergency lighting should be provided throughout the plant as necessary to support fire suppression actions and safe shutdown operations, including access and egress pathways to safe shutdown areas during a fire event. Detailed guidance on the acceptable design, testing and maintenance of emergency lighting is addressed in Regulatory Guide l.189. 7.1.8 Communications Plant communication systems, including hardwired and radio systems should be designed to provide adequate communication during fire events and should be protected from fire damage. The communication system design should provide effective communication between plant personnel performing safe shutdown, fire brigade personnel
