Improvements in Control Systems for Fire Pumps, Class A Foam Systems, and CAFS

Neal E. Brooks

"In the beginning" could refer to a biblical verse or a handful of new fire recruits gathered around an older, experienced firefighter explaining the virtues of "now vs. then." And, so is the story about the evolution of control systems in the fire service and how it has affected both apparatus builders and end users. I recently visited a small volunteer fire department in rural Seneca, Illinois, and viewed its fully restored 1911 Waterous hand-drawn pumper.

It was the first new fire truck the village of 1,000 purchased, and it arrived via box car on the railroad. I marveled at the simplicity of design but also questioned the quality of gasoline available at the time or how many fingers, wrists, or arms were broken starting the motor with the infamous Model-T-type crank start. There were exposed gears in the pump assembly and rudimentary operating gauges that gave the operator only better than a guess for what the pump pressure was. If the fire stream hit the target, then it must be the correct pressure, right? Yes, the good old days.

Well, to paraphrase my mother, who was raised during the depression, "The good old days are now!" So it is within the rank and file of the modern day fire service and those fire apparatus builders that strive year after year to make operating what has become a complex piece of machinery safer and simpler. Merely three decades ago, a phenomenon known as the Internet was just getting started. Who would have guessed how it would affect the global community or those in their own fire service? The information network, in my humble opinion, affected many changes in our own private fire society in a shorter timeframe than what may have transpired in the good old days. Manufacturers and end users were now able to compile useful information to make the dangerous job of firefighting increasingly more controllable from a safety standpoint. The improvements in training methods, personal protective equipment, thermal imaging, and tools of the trade have evolved into a continuum of progress toward the goal of being safer and smarter. Apparatus manufacturers were quickly on board to take full advantage of this newfound computer age to develop safer, smarter fire apparatus.

Not lost in that desire to improve fireground safety was the fact that the manufacturing industry had to do its part to improve product reliability and safety. National Fire Protection Association (NFPA) 1911, Standard for the Inspection, Maintenance, Testing, and Retirement of In-Service Automotive Fire Apparatus, and NFPA 1901, Standard for Automotive Fire Apparatus, probably bear the brunt of that platform and road map for developing, maintaining, and designing safer fire apparatus. One thing, for sure, is that apparatus operations today are light years ahead of where they were just 10 to 15 years ago. There may be a few of us left who can remember fire trucks with standard transmissions. We arrived on scene, shifted the PTO into gear (many times outside the cab of the truck), placed the transmission shift rod into pump gear, and "locked" it in with the pin or hook that caught the latch on the shift rod. This sounds pretty safe if it is what you had back in the 1950s and 1960s-and decidedly so, because, for many, that was the only option.

The Modern Evolution

With the advent of higher horsepower engines, stronger automatic transmissions, and increasing demand from end users for "bigger pumps" came what I deem the modern evolution of fire apparatus. Manufacturers had the capability to meet all of those demands, but where did safety play into the mix? I can recall far too many stories of apparatus "launching" from their blocks while in pump gear and other tragic fire apparatus accidents. Looking forward, the apparatus industry investigated methods to isolate fire pump control at th

ISO, NFPA, AND CLASS A REVISITED

By Bill Adams

Apparatus specifications (specs) published by fire departments, manufacturers, vendors, and consultants regularly refer to National Fire Protection Association (NFPA) 1901, Standard for Automotive Fire Apparatus, as they should. Some refer to a Class A pumper (Class A), which they shouldn't.

A few refer to the Insurance Services Office (ISO), which could result in a longer lasting financial impact on a community than using NFPA 1901 and Class A. Spec writers should understand the significance using each term may or may not have. There should be justifiable reasoning when references are included in a spec.

The intent of this article is not to split hairs over specification verbiage. The objective is to make purchasers aware that referencing the ISO and NFPA 1901 can have financial implications as well as operational consequences. Class A, on the other hand, is an ambiguous traditional term that has no formal definition. Its historical meaning is subject to multiple interpretations. Consequently, it doesn't belong in a specification.

The ISO's requirements have changed (for those jurisdictions that subscribe to them), and NFPA 1901's are about to. Spec writers should be cognizant of those changes.

ISO

According to the ISO's Web site, "ISO evaluates municipal fire-protection efforts in communities throughout the United States." It analyzes efforts, grades them, and assigns a rating to them, which underwriters use to set insurance rates. The ISO states it is an "advisory organization" and "insurers may use our information, modify it, or not use it as they see fit." Compliance is voluntary. Noncompliance may detrimentally affect a community's rating and ultimately the cost of insurance within it.

One ISO tool used to grade fire protection is the Fire Suppression Rating Schedule (FSRS). It evaluates three major criteria: fire department, emergency communications, and water supply. There are substantial changes to the 2012 FSRS, including a new section designated "Community Risk Reduction." Fire departments should understand the grading system, what is expected of them, and how they will be evaluated. I only address ISO changes to ancillary equipment carried on apparatus herein. It is a very small part of the grading process.

NFPA 1901

NFPA 1901 is a minimum standard for fire apparatus. I describe it as an unenforceable nationally recognized safety standard. The fear of legal action resulting from noncompliance influences voluntary adherence by manufacturers and end users. NFPA 1901's newest revision is due in 2016. It is unlikely a manufacturer will deliver a noncompliant rig unless it receives a sign-off from the purchaser per NFPA 1901 Sentence 4.4.1.2. Whether fire departments actually equip and operate apparatus per NFPA 1901 after delivery is questionable. I pass no judgment on that important local decision. Refer to NFPA 1901 Section 4.21 regarding responsibility. Be mindful-the definition of responsibility can encompass accountability and liability.

The authority having jurisdiction (AHJ) or a political subdivision at a local or state level may have legislation mandating NFPA 1901 and ISO compliance. The fire department, or even a professional association representing department members, may have contractual agreements requiring similar compliance. Understanding ISO and NFPA criteria and concurrent changes will benefit all parties. Exercise caution. Changes in NFPA 1901 and ISO requirements may place a financial burden on a community. There are no NFPA or ISO police, but there are tort lawyers.

Class A Pumpers

There is no formal description for Class A pumpers. NFPA 1901 does not address them nor does the ISO. But, purchasing specifications reference them on a daily basis. What do purchasers expect when they specify one? Most manufactu

Wildland Urban Interface Apparatus Assuming Larger Role in Many Department Fleets

By Alan M. Petrillo

Wildland and urban interface (WUI) vehicles are maturing into rigs that are playing an important role in fire departments faced with the challenging issues confronting them in WUI territory.

The dual ability of fighting either a structure fire or a wildland fire characterizes the typical WUI piece of apparatus. But, many variations on the type are being used, depending on the needs of the department, the budget available, and the lay of the land the vehicle needs to protect.

Record Year

"It's been bonkers-we've been building more wildland and urban interface trucks than in any other single year," says Doug Kelley, wildland product manager for KME. "The drought that's been going on in the western part of the country for years now encompasses much of the West Coast from California, Oregon, and Washington all the way back to Texas. Fires are getting bigger and hotter because trees and plants are drier, and fire departments are responding to the need to protect people who move into these dry areas."

KME builds a full line of apparatus for the fire service, Kelley notes, from Type 6 specialized wildland trucks through Type 3 medium-duty chassis wildland vehicles carrying 500-gallon water tanks or more, to WUI Type 1 pumpers with up to 750 gallons of water that can function as both structural and wildland units.

One of KME's more popular WUI models is its Ridgerunner, according to Kelley, a type of vehicle that's being used all over the country. "We recently built a Ridgerunner for a fire department in semirural Pennsylvania that has a wide range of hazards in its district-highways to farmland to industrial-so it needed a multiresponse vehicle," Kelley says. "We built the truck on a 4x4 International Navistar 7400 chassis with a 1,500-gpm Hale pump, 500-gallon water tank, and pump-and-roll capability. One of the compartments carries the department's hydraulic rescue tools, while another is dedicated to general firefighting tools."

Kelley points out that most departments want to perform some type of rolling fire attack with their WUI rigs. "They want the ability to do that with a turret on the front of the vehicle and with ground sprays," he says. KME's Whipline turret, developed in conjunction with Elkhart Brass, is gaining in popularity, he notes. "Whipline is fully operable from the cab and is quicker than the traditional electrically controlled nozzle. It's a manual valve that moves as fast as you can move your hand."

Popular to the North

Paul Christiansen, marketing director for Ferrara Fire Apparatus, says his company also has seen a lot of WUI market penetration in the western states but also in the Northeast. "Most of the vehicles have pump-and-roll capability, driven by a diesel auxiliary pump," Christiansen says. "They have a front bumper turret and monitor and usually have a hose reel or small trash line on the bumper too. Usually it's at least a 12-inch bumper extension carrying 50 to 75 feet of 1¾-inch hose, although some departments use one-inch forestry hose."
