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)

Drafting Tip #16 - Drafting During Storms - Oklahoma

President Mark Davis, August 16

Stormwater crossing a roadway can be deadly. We all know the "Turn Around Don't Drown" mantra and of course driving fire apparatus through floodwaters doesn't always work out so well. Occasionally, emergency incidents occur where FD drafting operations have to consider using water sources in a manner outside of the "norm." We certainly know of examples in Maryland and Northern Alberta where a pumper ... (Full Story & Photos)

No Caption Intake Fittings - What's the Flow?

President Mark Davis, August 09

A fire department pumper arrives new from the factory perfectly capable of flowing its rated pump capacity. Sometimes, the fire department choses to affix various intake fittings that in the end actually reduce the pumper's flow capability because of restricted orifices in the fittings. This situation becomes most problematic when choosing to leave the fittings in place during drafting operations. ... (Full Story & Photos)

Dry Fire Hydrant Design 17 - Swiveling Bridge Mount Design - Rising Sun, Maryland

President Mark Davis, August 02

In June we completed the design and installation of a bridge mounted swiveling dry fire hydrant on Calvert Road in Cecil County, Maryland. The installation was the second of its kind in the Rising Sun area and the second along North East Creek. The creek provides ample water supply in the area and Chief Donald Wehry and the folks at the Community Fire Company of Rising Sun like the swiveling design ... (Full Story & Photos)
