what should you make sure of prior to performing your turret ground pattern test?

Back 13

1)the water tank is full
2)the foam concentrate tank is full with the type of foam concentrate that is used during actual emergencies
3)the porportioner is set for normal firefighting operations
4)for premixed systems, the tank is full with the premixed soultion in the correct proportion for normal fire fighting operations

Front 14

to guarantee accurate test results for the turret ground pattern test what are some things to consider?

Back 14

1)wind conditions are under 5mph
2)turret nozzles are titled upward to form a 30 degree angle with the horizontal to determine the max discharge range

Back 16

60*F-80*F

Front 17

in expansion ratio, if the solution temperature is higher than 70*F is correction applied?

Back 17

no correction applies

Front 18

in expansion ratio, if the temperature is lower than 70*F what corrections is applied?

Back 18

add 0.1 unit of expansion for each 3*F below 70*F
