The firefighter, given the necessary equipment, shall read and record the flow pressures
to determine the discharge in gallons per minute.
II. II. II. II. Instructions Instructions Instructions Instructions –––– Procedures for Achieving the ObjectiveProcedures for Achieving the ObjectiveProcedures for Achieving the ObjectiveProcedures for Achieving the Objective
Given all of the necessary equipment, you shall record the flow pressures from two
different sized orifices. The examiner shall verify the readings. You shall then use the chart
provided and locate the pressure for each orifice. The examiner will indicate the pressure and the
GPM indicated by you on the bottom of this performance standard form. You will begin on my
instruction to start. The skill will end when you state to me that you have completed all of the
identified steps. Do you understand these instructions?
