On October 12th, Dover Fire and Rescue (New Hampshire) hosted our 8-hr LDH/Relay Pumping Seminar as part of their driver/operator (engineer) annual training. The focus of the seminar was relay pumping and nurse tanker operations specifically relating to water supply operations in the City where hydrant location and spacing are less than optimal. The participants were all experienced driver/operators and they got a chance to review the SOG and then put it into practice. Folks also reviewed the pump-off flow capabilities of local tankers as well as flow capabilities of fire hydrant outlets and hydrant-assist valves. Many thanks to DC Mickey Drouin and DFR for having us deliver our training program to the men and women of their department. Mark Davis was the seminar's instructor.
