The main gpm safety margins are for knockdown and flow reduction. You want to be okay if knocking the fire somehow requires more water than expected. You also want to be okay if a kink or some other mishap reduces the flow to the nozzle. Stream from a nozzle that is useless because of a kink in the hose Fig. 6-2 Kinks ruin your stream The reference point for the flow-reduction margin (RP-kink) is the bottom of the nozzle’s operating range. It’s the smallest flow that will provide a usable stream. The reference point for the knockdown margin is the smallest flow that will black the fire out. Any flow less than RP-Knockdown will fail to kill the fire. Any flow more than RP-Knockdown will give you a margin of safety. The actual number varies from fire to fire, so for planning purposes we take 30 gpm as an adequate residential RP-Knockdown. It would easily cope with all but the largest residential rooms. Your planned safety margin in each case is the difference between your target flow and the reference point. As with most safety margins, distance above the reference point will limit the benefit of a margin increase. If your RP is 30, a target flow increase from 40 to 60 would be valuable. A boost from 140 to 160 would not. It’s unlikely that the higher numbers would ever come into play.
Nozzle flow safety margins for automatic and smooth-bore nozzles at 100 and 150 gpm. Knockdown safety margins are very large in all four cases. Kink margins are big for automatic, but only about 29% for smooth-bore, regardless of tip size.
