Fixed Manual Fire Suppression Systems Some fixed fire suppression systems may be manually actuated (e.g., fixed suppression systems provided in accordance with Section III.G.3 of Appendix R to 10 CFR Part 50). Manual actuation is generally limited to water spray systems and should not be used for gaseous suppression systems, except DG-1359, Page 53 when the system provides backup to an automatic water suppression system. Fixed manual suppression systems should be designed in accordance with applicable guidance in the appropriate NFPA standards. A change from an automatic system to a manually actuated system should be supported by an appropriate evaluation. 3.5 Manual Firefighting Capabilities 3.5.1 Fire Brigade A site fire brigade, trained and equipped for firefighting, should be established and should be on site at all times to ensure adequate manual firefighting capability for all areas of the plant containing SSCs important to safety. The fire brigade leader should have ready access to keys for any locked doors. Regulatory Position 1.6.4 of this guide provides guidance on fire brigade training and qualifications. The guidelines of NFPA 600 are considered appropriate criteria for organizing, training, and operating a plant fire brigade. 3.5.1.1 Fire Brigade Staffing The fire brigade should include at least five members on each shift. The shift supervisor should not be a member of the fire brigade. 3.5.1.2 Equipment The equipment provided for the brigade should consist of personal protective equipment, such as turnout coats, bunker pants, boots, gloves, hard hats, emergency communications equipment, portable lights, portable ventilation equipment, and portable extinguishers. Self-contained breathing apparatuses using full-face positive-pressure masks approved by the National Institute for Occupational Safety and Health (approval formerly given by the U.S. Bureau of Mines) should be provided for fire brigade, damage control, and control room personnel.
