Forward-Looking Radar, 360-Degree Cameras Help Prevent Collisions

By Alan M. Petrillo

The safety of firefighters inside fire apparatus when traveling to and from an incident is of paramount importance to all fire apparatus manufacturers, no matter what type of vehicle they are constructing.

Strong structural members, air bags, electronic stability control, occupant detection systems, and other components address the safety aspects of a fire vehicle, but other technologies are also taking hold.

One apparatus maker, E-ONE, has developed a protection system that incorporates an additional two technologies new to fire service apparatus-a forward-looking radar that can detect developing rear-end collisions and a 360-degree bird's-eye view camera system that gives an operator situational awareness of his vehicle on the road.

ProTech

Joe Hedges, E-ONE's product manager for aerials and chassis, says that his company's ProTech system is a comprehensive safety package for all E-ONE chassis. "It starts with the roll cage cab we build that can withstand two times the National Fire Protection Association (NFPA) and Society of Automotive Engineers (SAE) impact requirements and five times the roof load requirements," Hedges says.

ProTech also includes front and side air bag systems with integrated seat belt pretensioners; electronic stability control that constantly monitors driving conditions; an occupant detection system that gives audible and visual warnings; backup sensors that warn a driver of potential obstacles at the rear of his vehicle; a 360-degree camera system; and OnGuard, the forward-looking radar system.

OnGuard

"We worked with our brake system supplier, Meritor Wabco, to integrate OnGuard into our chassis," Hedges says. "The system has dual zones-one that takes a wide and close look in front of the vehicle and the other up to 600 feet ahead to detect any kind of developing rear-end collision. OnGuard looks at thousands of items ahead of it but tracks in great detail six vehicles as to their speed relative to your speed."

Hedges says that OnGuard bases its calculations on the driver's steering position, the vehicle speed, whether or not brakes are being applied, and what the objects in front of the vehicle are doing. "If OnGuard detects a potential impact, it watches if its driver is doing something about it-for example, steering to avoid. If he is and that path is not clear, OnGuard will intervene. It's constantly watching all elements."

Internal or External? That Is the Question

Doug Miller

During the past several years, shrinking budgets have forced many fire departments to reconsider how they do business. Every expenditure is viewed under a microscope to make every dollar count and spend limited funds wisely.

Too many departments have had to delay purchasing much-needed apparatus during this time. This can only be put off for so long as aging apparatus may pile up huge repair bills, not be as safe as they should be, or not be the proper tools for the changing mission of your department. If this sounds like your department, then apparatus replacement should be one of the top line items in your budget. But, will you replace an old, worn out pumper with something that has nearly the same layout?

New Apparatus ConsIderations

Consider many factors for the new pumper, including the following:

  • The vehicle's mission: What has changed since the previous truck was built 10, 20, or more years ago?
  • Cab design: How many firefighters are available to ride the new rig?
  • Overall size: Can a smaller unit be just as effective?
  • Pump capacity rating: How much water is really available now and in the future?
  • Compartment size: How much equipment do we need to take along to cover the various missions?

As needs have changed, apparatus manufacturers have responded with many more options for nearly everything apparatus-related. To get more compartment space to carry all the equipment departments need to take along and to keep the overall size of the rig within reason, some areas in truck design have seen much change. Many new options involve pump location, the pump operator's location, and pump drive options.

Recently the Fire Apparatus Manufacturers' Association (FAMA) Technical Committee's Pump and Plumbing subcommittee embarked on a project to research and report the various pump configurations available today. The results will be published later this year as educational document TC024: FAMA Pump Selection Guide. The report will be available at www.fama.org. The goal is to educate, to an awareness level, those responsible for fire apparatus layout and design-i.e., fire truck specification committees and apparatus sales representatives.

As the investigation has evolved, many configurations have been discovered, all with pros and cons. Since space is limited in this article, I have chosen one topic that seems to come up on all pumping apparatus: pump intake valves.

The question is: What is the best choice for your primary pump intake valve when specifying your next apparatus? Let's compare different types of valves used to control water flow into the main (steamer) connections of your pump.

In general, there are two main types of valves: internal and external. The internal valve is an integral component of the pump intake plumbing. The external valve is mounted outside the pump and pump panel. They both perform the same function-controlling incoming water to the pump through one or more of the pump's primary water intakes. Both valve types must have a means to expel air from the hoseline when first charged. This prevents a slug of air from moving through the pump and hoselines to reach the firefighters at the nozzle. Either valve will also incorporate an automatic pressure relief feature to keep unwanted pressure surges in the supply line from impacting the pump, hoselines, and firefighters.

Pros and Cons

Let's look first at internal (integral) intake valves.

Pros include the following:

  • Most can be controlled remotely from the pump operator's po

Apparatus Purchasing: the Booster Reel

By Bill Adams

What is revered by traditionalists, belittled by progressives, dismissed by many, and misunderstood by most?

It has been around for 140 years and has seen plenty of fire. It has adapted to changes in the fire service, yet its popularity rises and falls like the tide. It's the booster reel. Although this article is specifically directed at today's booster reels carrying 200 feet of one-inch hard rubber hose, the history of the booster reel will allow a better understanding of it.

Chemical Hose and Reels

Flexible rubber hose was made possible by vulcanizing, a chemical process patented in 1844 enabling rubber to be formed into specific shapes and sizes. Also in the mid 1800s, Boston, Massachusetts, pharmaceutical professor James Babcock discovered that mixing sulfuric acid and bicarbonate of soda created a gas that could force water through a hose. The ratio of two pounds of soda and one pound of acid to five gallons of water could generate 200 pounds per square inch (psi) of pressure-enough to "boost" the mixture through the line. Early nozzles did not have shutoffs because the original rubber hose could not withstand the pressures generated. According to fire apparatus historian Walt McCall, Babcock chemical engines with ¾-inch noncollapsible rubber hose were introduced in 1873. Storage reels for the rubber hose followed in the 1880s. The Babcock chemical hose thread (CHT) became and still is today the fire service standard for booster hose.

Chemical hose and chemical reels were also known and advertised as booster hose and booster reels. McCall elaborates that Seagrave was the first manufacturer to introduce chemical reels on motorized apparatus around 1910. He says that in 1913, Ahrens Fox introduced the first water tank and hose reel used exclusively with plain water and an onboard fire pump. The Cincinnati (OH) Fire Department received 10 1913 Model D Ahrens Fox Booster Cars with reels vertically mounted beneath the driver's seat. A photo of a similar reel installation is in the late John F. Sytsma's book The Ahrens-Fox Album. Don't ask for it today-it's out of print. Eric Hannay of Hannay Reels says, "Vertically oriented reels tend to have a lot of problems over time-weight of the hose collapsing on the bottom disc, the misappropriation of radial bearings in that axis, and so on." Despite the differences between chemical and plain water systems, the booster description became synonymous for both as well as for the water tank itself.

PULSETECH PRODUCTS CORP. has restructured a cradle-to-grave battery management program (BMP), originally created for military equipment maintenance, to test, recover, and maintain 12-V batteries for commercial fleet managers in both private and public sectors.

Initially introduced to the military as the "Battery Manager Maintenance Program," PulseTech technicians had developed a mobilization and training equipment site guidebook that included new battery turn-in procedures, battery worksheets, constant charge maintenance, state of charge, types of equipment utilized, and hard-to-charge batteries.

PulseTech management decided to commercialize the program, working with numerous national and regional fleet and equipment maintenance managers to create custom programs that follow a basic six-step outline.

As part of the BMP, fleet and equipment managers employ a series of smart tools, including analytical testers, battery recovery chargers, battery stock maintainers, and th
