What's Coming?

Richard Marinucci   Richard Marinucci

Each year the theme of the December issue is “Fire Service Forecast: What We See Ahead.”

It is a chance to pull out the crystal ball and make a guess as to what can be expected in the next 12 months. You can call it whatever you want-prognosticator, swami, seer, or whatever-but I prefer to look at it as sort of a “weatherman.” I can take my best guess, and no one really expects me to be accurate 100 percent of the time. There are many areas of the fire service to consider: service levels (i.e., staffing), apparatus, equipment, training, and firefighter safety.

Service Levels

From a service level perspective, staffing volunteer organizations will continue to be a challenge. This is for a variety of reasons, many of which have been documented by various organizations and individuals. Some departments will continue to maintain their volunteer staff at numbers necessary to provide good service, while a majority will continue to be challenged. On the career side, there should be an uptick as more departments continue to transition to combination or career departments because of volunteer organizations’ challenges. In other career departments, I expect to see increases in staffing in an effort to adequately staff for the required job responsibilities. Many departments lost personnel during the economic downturn and are still not back to where they need to be. Also, Staffing for Adequate Fire & Emergency Response (SAFER) grants continue, which help in this area.

Apparatus

Another outfall from the economic downturn was that many departments postponed apparatus purchases. As the economy improves, there should be efforts to replace aging apparatus and purchase additional vehicles for specific needs. The apparatus will have more technological advances-some mandated and some provided by the manufacturers. These should help to improve reliability and ease of use. This does not imply that there will be no need for training and routine maintenance. Departments will need to continue to train personnel on proper apparatus procedures. In some cases, departments will look to specialized vehicles in an effort to meet the needs of the community and various requests for service. Some organizations will look to alternatives to sending engine companies to medical emergencies with less expensive apparatus. This will still be a challenge that depends on the staffing model of the department.

Equipment

Regarding equipment, expect continued improvements in technology and additional tools that take advantage of these advancements. Some of these will be used to improve performance and simplification. Some tools will become lighter and stronger. Those using technology will have more capabilities. One area that should be better is gas monitors. As more information becomes available regarding the dangers of the products of combustion and their effects on firefighter health and wellness-especially related to cancer-there will be more monitoring equipment to help identify hazardous environments and provide information to let firefighters know when air quality is within safe working limits that don’t require special protective measures.

Technology will continue to provide more and more information to and about fire departments. There is almost an overload now, and there is no indication that there will ever be a push to limit what is made available. This information will continue to spread even outside the fire service, and the public will have more access. The bad news is that they will

Hydraulic and Electric Racks and Coverings Help Keep Firefighters on the Ground

By Alan M. Petrillo

With fire apparatus getting taller and longer, firefighters have turned to electricity and hydraulics to help them get equipment on and off their trucks.

Hydraulic and electric ladder racks are becoming commonplace on fire apparatus today, while powered hosebed covers make securing hose and getting equipment simpler, safer chores.

Ladder Racks

Mike Adams, vice president of Ziamatic Corp., says Ziamatic makes three powered ladder rack styles under the Zico brand name, a standard two-arm ladder access system (LAS), a hydraulic LAS, and a single-arm ladder system. The standard unit uses a two-arm ladder rack mounted vertically on the side of the vehicle and is usually used with ¾ compartment storage, Adams says.

The hydraulic LAS uses electric over hydraulic encapsulated actuators, stores the ladders horizontally on top of the vehicle, and swings them down 48 inches for deployment, according to Adams. “Our center-mount single-arm ladder rack also stores ladders horizontally on top of the truck,” Adams points out, “and brings them down to a vertical position for firefighter use at about waist height. This type of system is often used on vehicles with high side compartments.”

Trapper Meadors, sales engineer for Precision Fire Apparatus, says that Precision manufacturers its own style of electric-over-hydraulic ladder rack. “It’s a single-arm rack that, once it swings out and down toward the ground, pulls back in toward the truck so the ladders don’t stick out so far away from the body,” Meadors points out. “It allows firefighters to deploy the ladders when they are in tight spots.”

Steve Touchton, emergency specialty product manager for ROM Corporation, says that while ROM makes Ergo Rack hydraulic ladder racks for commercial use-but not for the fire service at this time-its racks could be adapted to a Ford F-550-size vehicle or a Ford Transit-type van. “The system uses a hydraulic lever to counteract the balance so we are able to lower a 24-foot extension ladder gently to the ground by hydraulics over air cylinders,” Touchton says. “Depending on the vehicle and the type of ladders, some systems can be angled to the ground to allow one person to handle the ladder.”

Adaptive Steering for ERVs

By Christian P. Koop

The steering systems found in most heavy-duty fire apparatus and rescue trucks or emergency response vehicles (ERVs) have not changed much in the past 40 years.

Sure, most are heavy-duty, power-assisted steering systems that have been durable and reliable over the years, but when it comes to keeping pace with other technological innovations that have added improved efficiency and safety to the overall vehicle, it has not happened. This includes the ones rolling off the assembly line right now as this article is written. This is referring to the commonly used hydraulically assisted steering boxes or gear boxes found on most medium- and heavy-duty trucks. Most of these are the recirculating gear or ball-nut type with hydraulic assist and generally installed directly onto the driver’s side frame rail. There are some with electronically variable steering that basically change how much effort the driver has to use to turn the wheel, and it changes in relation to road speed by increasing or decreasing hydraulic assist pressures.

There are several variations of these. However, most importantly, they are all fixed ratios, meaning the speed at which the wheels turn in relation to the driver turning the steering wheel is the same throughout the complete range of steering. This is sometimes referred to as lock to lock or stop to stop. Important to note also is that steering speed does not change in relation to vehicle speed either. The systems have reduction ratios so drivers can have a mechanical advantage, and engineers design the systems to find the best balance between reduction and steering speed for each application. But, the main point here is it is still a fixed-ratio system.

New Technology

In one of my past articles, I wrote about how commercial trucks, in general, seem to lag behind the automobile industry in technological improvements. The same goes for ERVs. Well, Ford Motor Company just came out with a new steering system it calls adaptive steering, which is a great innovation in steering technology that will make steering easier; more efficient; and, when it comes right down to it, especially for ERVs, a safer steering system for all drivers and operators. Some manufacturers have made changes to the front suspension by offering independent suspension over the traditional I-beam in search of better performance and ride quality, but when it comes to the steering ratio, there have been virtually no changes, and most are all still fixed. This can be a detriment to the driver because a fixed ratio is still a tradeoff between providing safe, comfortable steering response at higher vehicle speeds and ease of steering and maneuverability at slow speeds. This also includes fire apparatus and ERVs in general. I have also written about the difficulty and danger involved in driving ERVs, particularly while on an emergency call, and Ford’s new system will definitely help in this vital area.

It may be several years before the ERV original equipment manufacturers (OEMs) develop and produce adaptive steering for the medium- and heavy-duty market. If some of these improvements could be introduced to the ERV market sooner than seen in the past, it would mean a big leap in technology for this industry. Improved safety is generally the main goal of major innovations that have come out over the past 25 or so years from the auto and truck manufacturers. The innovations that have made major improvements in safety help the driver maintain directional stability or from losing control of the vehicle. Keep in mind that the main goal behind these innovations is to reduce accidents and save lives. These major leaps in technological improvements are now common on most vehicles and include antilock brake systems (ABS), automati
