Water Tanks for Fire Apparatus

BY CHAD FALLS

More than 30 years ago, fire truck manufacturers started using plastic for their water tanks. With that being said, I am going to walk you through the history and evolution of plastic water tanks in fire apparatus from my perspective.

Along the way, I’ll explain why it is important not only to buy trucks and tanks from Fire Apparatus Manufacturers’ Association (FAMA) members but also to make sure that you are using the FAMA buyers guide, which ensures the best decision for your department.

HISTORY

First, let’s go back to the early 1980s. Alongside the copious amount of perms, glam rock, and spandex, the plastic welding industry was also starting to grow in the United States. While entrepreneurs and engineers were working hard to come up with the best design for water tanks, I was just a kid chasing frogs, building forts, and probably sporting a mullet (thanks, Mom). In all seriousness, we owe a lot to those innovators who worked along with and for fire apparatus manufacturers. Ultimately, they helped pave the way for the future of plastic fabrication and water tanks. Looking back, it’s amazing to think that without their efforts, I would not be here writing this today.

It did not take long for fire truck manufacturers to see that these new tanks made from plastic solved a major problem. Plastic is a noncorrosive product, so it eliminated the possibility of rust and leaks caused by corrosion. These tanks were first built from homopolymer polypropylene, a material that held up great against forms of corrosion but failed miserably when introduced to impact or extreme stress tests. That is when FAMA members that produce plastic water tanks started using their own version of a copolymer. Most of this product is still polypropylene, but with the benefits of some polyethylene, this product became bulletproof. No joke—this material is bulletproof to a .45 bullet at point blank range. Now, I should add a disclaimer here: This is not the time to try and shoot your water tank, as it is extremely dangerous! However, if you really want to see it, e-mail me and I will send you the video.

Over the past 25 years, FAMA members that produced water tanks also started adding “baffles” to the tanks. No, I’m not trying confuse you with the word baffles, so I’ll add that they are flow directing obstructing veins or panels inside of plastic tanks. They made the tanks much safer options for firefighters. Tanks baffled correctly are now much easier to deal with when turning, starting, and stopping the trucks, as the water is no longer constantly shifting weight. By adding them, tanks were made much stronger because the baffles also created tremendous support. Fun fact: This was such an important design element of the tank that it is now included in National Fire Protection Association (NFPA) 1901, Standard for Automotive Fire Apparatus; NFPA 1906, Standard for Automotive Wildland Fire Apparatus; and NFPA 414, Standard for Aircraft Rescue and Fire-Fighting Vehicles.

Fire Apparatus Used as Blocking Rigs

Chris Mc Loone

“Fire Engine Crashes En Route to Fire,” “Fire Apparatus Overturns,” “Man Hospitalized After Accident with Fire Apparatus,” “Driver Injured in Fire Apparatus Accident”—these are just a few of the headlines we’ve run at FireApparatus.com since the start of 2019.

Chris Mc Loone

Some involve civilian drivers hitting parked fire apparatus; some involve the apparatus hitting something else. So, we’ve got some work to do to improve these things during 2019. Naturally, accidents happen. No one is arguing that. However, preventable accidents during a response, to me, are unacceptable if they are preventable by the crew on the rig.

Fire apparatus being hit when they are properly staged to block traffic is a different problem and one whose solution has evaded the fire service. Departments are being proactive. Some stage multiple units. Some have started repurposing retired rigs to serve as blockers only. It can’t possibly be that drivers cannot see us on the road—at least not newer rigs with LED lighting packages. We responded to a recent job where two police vehicles blocked traffic, yet people still drove through. Maybe the problem is just that no one sees putting out a building fire safely or extricating a driver or passenger safely as more important than finding a different route to buy a gallon of milk.


Chris Daly continues his series of articles this month covering fire apparatus rollovers. By touching on topics not often covered during an emergency vehicle operation course, the article series provides information for apparatus operators to keep in the back of their minds as they respond to hopefully reduce the number of rollovers throughout the year.

But, we also have the problem of firefighters and fire apparatus being struck at accident scenes. The instances do not seem to be going down. Distracted driving, driving under the influence, and cars with increased soundproofing are just a few of the problems. The solution has remained elusive. And, people don’t only ignore fire apparatus. I walk my kids up the street every morning to their bus stop. At least every other day, the bus driver has to honk the bus’s horn at a car that doesn’t stop when its red lights are on.

So, what is the solution on the fire truck side? I like the idea of taking old rigs that are being retired and repurposing them as blocking trucks, provided they are still reliable enough to start up when needed. Depending on their age, I do hope that they will be hooked up to diesel exhaust extraction systems of some sort, especially if they are near turnout gear. Even late 1990s rigs pipes can belch some dark diesel exhaust.

What is interesting to me, though, is that there really aren’t any standards that cover when a vehicle is repurposed. National Fire Protection Association (NFPA) 1901, Standard for Automotive Fire Apparatus, covers new trucks. NFPA 1912, Standard for Apparatus Refurbishing, covers fire apparatus that still serve their original purpose but have been refurbished to continue as reserve pieces or many times first-out rigs. But, there isn’t anything about what you do when you are repurpos

Departments Going Smaller with Rescues, but Heavy Rescues Still Popular


Many fire departments around the country are leaning toward smaller rescue trucks compared with rescue trucks built five to 10 years ago.

Some departments cite budgetary considerations, some staffing issues, and others the ease of use and greater mobility of smaller rescue trucks. While this movement toward smaller rescues is taking place, several manufacturers report that the rescue trucks coming off their production lines continue to be midsize single-axle rigs or heavy single- or dual-rear-axle rescues.

UNRUH FIRE

Todd Nix, apparatus consultant for Unruh Fire, thinks that budgetary considerations are the main reason that a fire department chooses to build a small rescue. “Cost of the vehicle will dictate the size of the truck they build,” Nix says, “usually on a Ford F-550 or Dodge 5500 chassis with a nine- to 12-foot body. Typically, there’s a single compartment on each side, although we have built small rescues with a transverse compartment. Then there are some departments that want full access from a large slide-out tray at the back of the rescue.”

SUMMIT FIRE APPARATUS

Joe Messmer, president of Summit Fire Apparatus, says he has seen movement for some time in the rescue truck market toward smaller vehicles like those on Ford F-550 size chassis. “We’re doing more small- to medium-sized rescues these days, although we still get orders for heavy rescues,” Messmer observes. “For instance, we built a rescue for the West Chilton (AL) Fire Department on a Dodge 5500 chassis with a 19,500-pound gross vehicle weight rating (GVWR) and also a heavy rescue with a Fire Boss self-contained compressed air foam system (CAFS) for the Alexandria (KY) Fire Department.”

Messmer believes that the considerations of using smaller rescue trucks, including those on International 4400 and Freightliner M2 chassis, are being driven by personnel shortages, greater maneuverability, and purchase cost.

SVI

Bob Sorensen, vice president of SVI Trucks, notes that while SVI has built some smaller rescues on Ford F-550 chassis, like one it built for the Eagle Pass (TX) Fire Departm
