LDH/Relay Pumping Seminar in New Hampshire

President Mark Davis, October 18

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 ... (Full Story & Photos)

Hauling Water - New York Style!

President Mark Davis, October 11

Folks from the southern end of Tompkins County, New York spent last weekend refining their water hauling skills by participating in our 16-hr Rural Water Supply Operations Seminar. The seminar was sponsored by the Tompkins County Fire and EMS Chiefs Association and was hosted by the Brooktondale VFD. The seminar culminated on Sunday afternoon with the 2-hour tanker shuttle exercise. Four engines ... (Full Story & Photos)

Rural Pump Operations in Punxstuwaney

Senior Associate Alan Butsch, October 04

Instructors Alan Butsch and Chris Reilly visited the folks at the Punxsutawney Fire Department last weekend and delivered our 16-hr Rural Pump Operator Course. The goal of the course is to cover as many as pumping skills as possible over a weekend. Class participants all learned basic and advanced drafting skills, how to operate multiple attack lines, how to fill a tanker, and how to pump a basic ... (Full Story & Photos)

Tanker Operations #16 - Vacuum Tanker Loading Station Using a Dump Tank

President Mark Davis, September 27

As we have noted before, one of the advantages of a vacuum tanker is its ability to self-load and meet or exceed the NFPA 1901 minimum fill rate requirements while doing so. At our August 2018 rural water supply drill in Windfall, Indiana, one of the seven tankers hauling water was a 3,000 gallon vacuum tanker from the Bass Lake FD. Because the water source was several hundred feet from where tankers ... (Full Story & Photos)

Bass Lake FD's Tanker 15-85 self-loads from a 3,000-gallon dump tank at the fill site. Each time when the tanker was full, the loader crew broke the connection and the tanker headed to the dump site leaving behind the suction strainer and hose ready for next time. Note: to prevent siphoning when the tanker is gone, the floating strainer had to be pulled off the surface of the water each time.

Fire hydrant flow testing is just one example of the importance of using calibrated test gauges. The data from fire hydrant flow testing is often used by fire protection system designers to make critical determinations about the need for a system fire pump and other key components of a fixed-fire suppression system.

The Importance of Test Gauge Calibration

President Mark Davis, September 20

When conducting any type of flow testing on fire protection systems it is important to use calibrated test gauges. The old saying of "garbage in/garbage out" holds true if our test gauges are not calibrated. A good example is a project that we have been working on at a local airport complex. A private fire water protection system already exists in the complex. The system has large water mains, numerous ... (Full Story & Photos)

Tanker Operations #15 - Nurse Tanker Operations Using a Gated-Wye- Not Ideal...But Functional

President Mark Davis, September 13

During the early phases of fire attack operations, getting water on the fire as quick as possible tends to "make things better." In many locales, fire departments use nurse tanker operations to support the initial fire attack while waiting on additional resources to arrive...and then a decision is made regarding expansion to a dump tank operation.

The folks most successful with nurse tanker operations ... (Full Story & Photos)

Fill Site Operations #04 - Portable Pumps Used for Open-Relay

President Mark Davis, September 06

Portable fire pumps can be used in a number of applications in the water supply delivery process. The most important part of using these pumps is learning ahead of time each pump's capabilities and limitations. Most portable pumps have volume/pressure ratios that allow for reasonable flow but at lower pressure. For example, a portable pump might have an output rating of 400 gpm but at 25 psi discharge ...

The Amenia Mile...Pumping Water New York Style!

President Mark Davis, August 30

On Sunday afternoon, August 26th, folks from several departments in Dutchess County, New York gathered at the Amenia Fire District to participate in a large-scale relay pumping drill. The drill was the culmination of our 8-hr LDH/Relay Pumping Seminar that was sponsored and hosted by the Amenia Fire District. A 5,300-ft lay of 5-inch LDH was used to examine the flow capabilities, pumping requirements, ... (Full Story & Photos)
