250
26
pumpers with a tank capacity greater than 500 gpm must be capable of flowing a minimum of
500 gpm
27
if an apparatus achieves less than 90% of its original rated capacity what 2 options exist
may be removed from service & repaired be given a lower rating
28
true or false, NFPA 1911 requires foam proportioning devices to be tested on an annual basis
false
29
what 4 methods are used to test foam proportioning equipment
displacement method pump discharge volume method solution refractivity method solution conductivity method
30
what does concentrate displacement method test
accuracy of volume of concentrate drawn through system
31
what does pump discharge volume method test
direct injection systems
32
define refractometer
measures amount of foam concentrate in the solution. using light velocity like x ray
