Summary

Original illustration for Common cause failure, level 4 Expert.
- Source basis: Barry (2002), p. 5-203 (fire pumps a common cause failure to numerous deluge water spray systems after pump house flooding; valves shut for fear of freezing); Nowlen et al. (2005b), p. 13-7 (fire pumps, firefighting water piping, standpipes and storage tanks as seismic common-cause items); redraw, do not copy
- Alt text: Schematic: one water tank and pump house feed a main that supplies three deluge systems; flood, freezing and earthquake act on the shared part.
