Tanker Operations #20 - More About Commercial Water Haulers

President Mark Davis, June 25

Digging through some more old photos we found these from our trip to Alabama. We don't know much about the rig in terms of capacity or pump size (it was parked in the hotel parking lot), but we do know that in a pinch it could be used to haul water to a fire. The rig most likely would work best at some type of wildland fire where flow requirements are somewhat low and where it could be used to refill ... (Full Story & Photos)

While not efficient for structural fire attack water supply operations, don't discount the ability of this commercial water hauling rig to support other non-structure fire related water supply events.

Fill Site Operations #09 - Keep It Simple and Organized

President Mark Davis, June 18

While spending some of our quarantine time looking back through photos from our past seminars we found a couple from our June 2013 seminar in Turtle, Wisconsin and it reminded us of the importance of simplicity and organization at a tanker fill site. The fill site shown in the photos was one of several used to support a 2-hr water supply drill. A pumper drafted from a creek and supplied water via ... (Full Story & Photos)

Dry Fire Hydrant Design 29 - Flooding Damage/Protection

President Mark Davis, June 11

Many thanks to Frank Krick of the Harford County Department of Emergency Services for sharing some photos that he recently took of several of our bridge mounted dry fire hydrants in Harford County. Earlier in the month Harford County suffered a significant rainfall event that lead to flash flooding on a number of the streams and creeks where our bridge-mounted dry fire hydrants are located. It is ... (Full Story & Photos)

Dump Site Operations #19 - When Pumping Off is the Only Choice

President Mark Davis, June 04

The importance of knowing how mutual aid tankers offload their water cannot be overstated. At small incidents, you generally find that the companies that respond are also companies that work together on a regular basis. However, on the big incidents, we can often have a couple dozen departments forced to work together who rarely ever see each other. Ideally, every mutual aid tanker should offload ...

Dry Fire Hydrant Design 28 - Connection Stress

President Mark Davis, May 28

One of the common issues with dry fire hydrant design and installation is creating too much suspension of the suction hose when the pumper is connected to the dry fire hydrant. Ideally, suction hose should have at least one point of ground contact while the pumper is drafting. This point of contact takes some of the load off of the suction hose coupling which can be prone to leaking...especially ... (Full Story & Photos)

No Caption What's on Your Engine Company #02 - Pine Grove, PA

President Mark Davis, May 21

We have been looking through our photo albums these last couple months and trying to share some stuff that we haven't shared already. This week takes us back to our 2016 seminar in Summit Station, PA where we spent the weekend hauling water with tankers. While there we came across Engine 58-15 from the North End Fire Co. in Pine Grove, PA. An older model E-One pumper with "speed lays," the folks ... (Full Story & Photos)

Dry Fire Hydrant Repair & Maintenance #09 - Replacing a Defective Suction Head

President Mark Davis, May 14

We recently completed a small repair project involving a defective suction head on a 30,000-gallon underground fire protection water storage tank. The local FD had tested the tank and found they could not hold a draft. The test was part of the approval process for occupancy of a structure on the property. The tank was more than 15 years old and the structure had sat vacant for several years. The ... (Full Story & Photos)

The defective head appears that it was constructed on site from several PVC components and a "thread-in" fitting.  The coupling also leads us to believe the fitting was broken once before.

Keeping a lane of traffic open at a fill site is one of the critical points of a successful tanker shuttle operation...especially if empty and loaded tankers have to pass each on the same road.

Fill Site Operations #08 - Try to Keep a Lane Open

President Mark Davis, May 07

When running a tanker shuttle operation a critical feature of a successful operation is keeping the tankers moving between the dump and fill sites. When setting up a tanker fill site, folks have to envision the route of travel of incoming and outgoing tankers as well as how the loading process may block up access in and out of the site. Once the fill site pumper is positioned and ready to load tankers, ... (Full Story & Photos)
