Demers Ambulances FIRE TRUCKS AND VEHICLES

For those responsible for procuring and managing fire vehicle fleets, speed, driveability and reliability are paramount concerns. As well as the ability to accelerate, slow and stop rapidly and safely in city traffic, fire engines need to be highly manoeuvrable in tight spaces or on rough terrain. They are required to access many different types of environment at high speed, and, even more than other types of heavy-duty vehicles driven at slower speeds by professional lorry drivers, they need to be easy to operate. At the same time, vehicles are needed that are large and powerful enough to carry fire crews, heavy specialist equipment and large quantities of water or foam. They must also provide a smooth ride, for when crews are wearing bulky items such as masks and oxygen tanks. And they have to be extremely reliable, as breakdowns can cause loss of life. In recent years, manufacturers have generally preferred to specify fully automatic transmissions For all these reasons, fully automatic transmissions are now specified on most European fire vehicles, particularly in Germany, France, Spain and the UK. Compared to manuals, they can offer up to 35% quicker acceleration, with more torque at launch as well as no power interruption during gear changes upwards or downwards, enabling quick deceleration of the vehicle and bringing appliance to a complete stop when combined with an Allison Transmission retarder. That all adds up to faster response times and better manoeuvrability on crowded city streets. Automatics are also far more reliable and durable than manual or automated manual gear boxes, which are prone to wear and tear, particularly on the clutch. A key benefit that most automatics offer is a torque converter, which eliminates the need for a clutch altogether. automatic transmissions Compared to manuals, they [fully automatic transmissions] can offer up to 35% quicker acceleration This was the rationale for the specification of Allison automatic transmissions on London Fire Brigade’s latest Mercedes-Benz Atego and Scania trucks. “The Allison [automatic] transmission was specified partly because of its responsiveness and controllability, and partly because it has proven itself to be such a reliable solution for LFB’s operations,” Neil Corcoran, engineering and technical manager at Babcock International Group, which manages and maintains the LFB fleet, told us." We have seen for ourselves that the Allison has minimal maintenance requirements. And, of course, the dependability of equipment is essential in emergency services.” Allison has a dominant position in the European fire sector, where it has spent decades designing and building fully automatic transmissions that perform at their best in critical situations and offer vital benefits not provided by manual or automated manual transmissions (AMTs). This is particularly true in airport fleets, where vehicle response times are dictated by legislation. London Fire Brigade has a large number of Mercedes-Benz Atego fire trucks, all equipped with Allison transmissions Cleaner fuels In recent years, manufacturers have generally preferred to specify fully automatic transmissions. This continues to be true now when, in common with other commercial vehicle markets, they are looking at alternatives to diesel fuel, such as compressed natural gas (CNG) or liquefied natural gas (LNG), to reduce emissions in the medium to long term, particularly in urban areas. Automatics are far more reliable and durable than manual or automated manual gear boxes, which are prone to wear and tear Automatics tend to be well suited to both compressed and liquefied natural gas engines because the torque interrupts that occur with manual and automated manual transmissions during gear shifts are more volatile and less predictable in the case of spark-ignited CNG and LPG engines. Automatics, by contrast, can provide a smooth transfer of power to the drive wheels and maximum efficiency between engine and transmission, resulting in better performance, manoeuvrability, safety and driver comfort, as well as a significant reduction in noise. In 2019, German fire engine manufacturer Magirus revealed the world's first compressed natural gas (CNG)-powered firefighting vehicle in series production. Part of the company’s 'Innovative Drive Line (iDL)' series, the (H) LF 10 fire engine has an Iveco Eurocargo 4x2 chassis with 420 litres of CNG and a fully automatic Allison transmission. It has a range of up to 300 km or pump operation of up to four hours. Speed and power for forest fire vehicles Automatic gears are also increasingly specified on 4x4 vehicles used to tackle forest fires as they outperform AMTs in extreme conditions. Forest firefighting vehicles need to be able to carry powerful, high-capacity pumps and canons as well as very large quantities of water or other extinguishing media. And they must be able to travel rapidly over large distances and very rough and steep terrain, in extreme heat. AMTs and manual transmissions cannot cope well with these conditions. An example of a newly launched automatic forest firefighting vehicle is the Spanish-made UROVESA K6 IS, which is equipped with the Allison 3000 Series™ transmission. It features a chassis with a maximum gross vehicle weight (GVW) of 16 metric tonnes, excellent traction and extremely robust parts. According to UROVESA's President and CEO Justo Sierra, the automatic transmission, combined with an independent suspension system, affords greater guarantees of safety and efficiency than other vehicles and is in great demand for forest firefighting applications because it can travel at twice the speed of conventional 4x4 trucks. "These transmissions facilitate driving, prevent gear shift errors, enable both hands to be on the wheel at all times and enhance driver ergonomics and safety," explained Sierra. The UROVESA K6 IS forest firefighting vehicle, made in Spain, equipped with a fully automatic transmission. It can travel at twice the speed of conventional 4x4 trucks combating vehicle rollback There are a number of ways in which automatics help reduce accidents and improve driver awareness, comfort and safety, from combating vehicle rollback – a major concern with manual transmissions – to providing superior vehicle control and manoeuvrability at low speeds. Furthermore, because the engine’s responses are so closely related to what the driver asks of it, the vehicle’s start-up progress is more predictable to cyclists and pedestrians who might otherwise misinterpret a slow start as an intention to remain stationary. Electronic features like putting the transmission into neutral when leaving the cab or safety interlocking with body equipment further reduce the risk of accidents. Built to last Fire vehicles tend to be in use for only a few hours each week, with low mileage. Consequently, they can be operational for up to 25 or 30 years. So it's even more important for fleet buyers that they get specifications right, to ensure their vehicles will pass the test of time and provide the performance they need for decades. That's one more reason why so many continue to opt for Allison planetary automatics.

Want to know an easy way to judge the quality of a fire department? Look at how much they train. Career, volunteer or combination, fire departments become successful through training. Yet all training is not equal. Focus too much on hands-on training (HOT) and you could be missing important legal and compliance updates. Lean heavily on web-based training and you may fail to identify shortcomings in skills proficiencies. Keep students confined to a classroom and you may lose their interest quickly. Not surprisingly, a balance of all three types of training is needed to produce competent, empowered firefighters. For this article, I was challenged to think about what’s missing from our current fire training programs. As I thought about the varied way we approach fire training, three issues jumped out at me. Base training on facts and statistics Take advantage of new technologies Incorporate policy into your training   Your training program should also be strong in the types of calls you respond to most Base Training On Facts And Statistics If your department has a robust training program, outlined by a calendar of various topics and employing a mix of HOT, online and classroom training, you’re ahead of the curve. But even in departments with well-developed training programs, training is often based on preference or habit, not data. Think about the topics in your training program. Do you know why they’re included? Do they match your call make-up? Are they targeting specific skill shortcomings? (And yes, we all have them!)What’s missing from many fire department training programs is a detailed needs assessment What’s missing from many fire department training programs is a detailed needs assessment that in turn establishes a factual basis for the year’s training topics. The needs assessment should include: Surveying the members to determine the types of training they want or feel they need. Measuring firefighter proficiency on basic tasks, such as NFPA 1403 drills, NFPA 1710 drills and EMS patient assessment skills audits, to assess personnel by mandate or by industry best practice. This will identify skills deficiencies to address through training. Incorporating call volume statistics and details. A significant percentage of the calls fire departments respond to are EMS and vehicle extrication But I’d venture to guess the training programs of most departments don’t match those percentages. Yes, you need to train for the high-risk, low-frequency tasks. But your training program should also be strong in the types of calls you respond to most. Incorporating these “facts and stats” into your training program will help you keep it fresh, relevant and interesting. Firefighters can use their phones and tablets to access department training information and complete training assignments Take Advantage Of New Technologies There is something to be said for back-to-the-basics, keep-it-simple firefighter training. But it’s a mistake to ignore technological advances. From teaching safe apparatus backing procedures to practicing hoseline deployment and Vent/Enter/Isolate/Search (VEIS) tactics, instructors have more options than ever before. Some instructors regard simulators as second-rate to “the real thing.” Certainly, simulation and other forms of technology-driven instruction can’t replace the value of hands-on experience. But they can augment it in important ways. Driver simulators, for example, not only save money because apparatus don’t have to be taken out of service or sustain wear and tear; they also provide an environment where firefighters can learn without risk of injury. If sitting behind a computer isn’t your kind of thing, live-burn simulators, vehicle fire simulators and hazmat simulators are available—and they all significantly boost training efficiency.Technology will never replace hands-on instruction, but it can facilitate it But you don’t need fancy simulators to incorporate technology into your fire training program. Learning management systems (LMS) are another important tool that can increase training program efficiency. Although they’ve been around for a long time, LMS continue to improve. The ability to integrate with mobile devices is huge, allowing firefighters to use their phones and tablets to access department training information and complete training assignments. Leveraging this technology can allow you to more efficiently manage information, schedule training and free up valuable time needed for other important tasks. If you’ve attended some of the larger regional or national fire conferences recently, you may have had the opportunity to see audience response technology in action. By capturing the firefighters’ responses to questions in real-time, instructors can adjust the material to reflect students’ knowledge level. Audience response is also simply a great way to keep firefighters engaged. Technology will never replace hands-on instruction, but it can facilitate it. If you’re using training methods that haven’t changed in decades, something’s missing from your training program.   Without incorporating policy into your training, you’re only giving your firefighters half the equation Incorporate Policy Into Your Training I saved the biggest and best for last. When I work with fire departments across the country, I repeatedly discover the failure to incorporate policy into training. Think about it: Training curricula are almost always designed around procedures—the how of doing something. But isn’t the why just as important? And that’s what policy is all about. Without incorporating policy into your training, you’re only giving your firefighters half the equation.Inevitably firefighters will encounter times when following the procedure isn’t possible Inevitably firefighters will encounter times when following the procedure isn’t possible. That’s when policy training kicks in—firefighters understand the fundamental objective, and they can think on their feet about how to achieve it. Training on policy also helps departments address the issues that so often get firefighters into trouble. How many of your firefighters really understand your department’s social media policy? What about the rules surrounding sick time usage? These are things that trip up firefighters time and time again. If you’re not training on policies, it’s unlikely firefighters remember them. How many of your firefighters really understand your department’s social media policy? In addition, normalization of deviance is a risk to every organization. When personnel fail to follow policies and no negative repercussions result, it can quickly establish a new normal. Policy-based training resets the “normal” and makes sure that members of the organization comply with the policy and not what they think the policy says.Most line-of-duty death reports cite failure to comply with policy or lack of adequate policy Fire instructors often avoid training on policy because they regard it as boring or unrelated to what really matters—firefighter safety and survival. Yet most line-of-duty death reports cite failure to comply with policy or lack of adequate policy as contributing factors in the incident. If you’re worried that policy will make your training program dry and uninteresting, link it to real-world events. An online search provides lots of examples of when things went wrong and how adherence to policy might have produced a different outcome. And limit policy training to small chunks. Take out a 10-page policy and go through it line by line, and your students’ eyes will glaze over in seconds. Instead, look for ways to enrich your current training by bringing relevant pieces of policy into it. Your firefighters will be learning the department’s policies without even realizing it! Focus On Continuous Improvement Fire chiefs and fire instructors have a challenging job. Budgets are tight, and training is often one of the first things to be cut. Yet we need firefighters to be proficient in all-hazards response. Every department has a long training wish list. But if we focus on continuous quality improvement, we can get a little better each year. Looking for opportunities to incorporate statistics, technology and policy into our training is a good place to start.

Within traditional commercial and industrial firefighting systems, engineers have primarily focused on permanent installation designs rather than entertaining alternative or supplemental mobile firefighting systems. Permanent installation design is typically better understood, supported, and supplied throughout the fire protection engineering and manufacturing community. However, mobile firefighting systems provide unique solutions and advantages compared to their permanent installation cousins such as flexible deployment, simpler servicing, improved economy, and much higher performance availability. The combination of both systems is frequently the most strategic solution for the facility operator. Limitations of fixed installation systems Permanent installation (fixed) systems include everything from sprinklers, foam systems, primary watermain pumps, and the plethora of piping in between. A large refinery complex will need to address various hazard mitigation and control problems that span both hardware and personnel needs. In the event standard hazard mitigation safety procedures and equipment have failed, the facility immediately initiates a hazard control operation. Passive fixed systems automatically engage the hazard through an array of sensors, mechanical triggers, and control algorithms. A properly designed system with adequate hazard coverage, preplanning, preventative maintenance, and testing will successfully terminate the hazard, while firefighting personnel respond and ensure no further hazards develop. This conceptual approach relies on hardware and personnel all operating as planned…. Combining permanent and mobile apparatus “According to plan” would never have any failures or fires, but history has a different script. In the worst-case petrochemical scenario, fixed systems fail to extinguish a hazard putting the entire response on human and mobile hardware resources. This would include but is not limited to firetrucks, mobile high-flow pumping systems, large mobile monitors, foam proportioning units, and large diameter layflat hose. This type of response escalates into a larger scale operation, sometimes involving agencies beyond the facility operator itself. Although a low probability event, the risk to life and property is significantly substantial. Fixed systems may be rendered inoperable due to the loss of electrical power or actual physical damage Reducing fire-related expenditureMore typical than the worst-case scenario, facilities experience both maintenance-related system downtimes and natural phenomena damage such as extreme weather and seismic events. In this case, fixed systems may be rendered inoperable due to the loss of electrical power or actual physical damage. In any of these situations, mobile fire apparatus may fill the gap requirements of the facility as their flexible storage and deployment would protect them from everything but the worst natural disasters. Their further benefit is that a smaller set of mobile apparatus resources may be used to protect a larger amount of infrastructure, especially while in use in a mutual-aid program between facilities and communities. According to the NFPA’s report “Total Cost of Fire in the United States”, fire-related damages and expenditures from 1980 to 2014 have risen from roughly $200B (adjusted for inflation to 2014) to nearly $330B. The greatest expenditure is in fire safety costs in building construction, amounting to $57.4B. Although the overall losses per year as a ratio to protection expenditures has dropped by roughly 70% over the past 30 years, petrochemical facility losses have continued to rise over the same time. In the worst-case petrochemical scenario, fixed systems fail to extinguish a hazard  Petrochemical facility challenges According to the NFPA, refineries or natural gas plants had reported an average of 228 fires or explosions per year through the 1990s. Furthering this data with Marsh’s “100 Largest Losses, 25th edition”, refinery losses have continually expanded throughout the last two decades with 11 of the top 20 largest losses of the past 40 years happening during or after the year 2000. Two primary drivers of this trend are the advanced age of petrochemical facilities and their staggering complexity. As oil margins fall, upstream operational businesses are detrimentally affected by reduced investment in everything to new equipment, maintenance and passive safety systems. There is an observable correlation between a major oil price drop followed by upstream facility fire losses. Even with reduced investment and oil throughput growth rates, US refinery utilisation at the end 2017 was at 96.7%, the highest since 2005 (Marsh, The Impact of the Price of Oil). The short story is that systems and personnel are being asked to do more with less with each passing year. Cost-effective mobile apparatus systems  Mobile fire apparatus is generally more cost-effective to procure when using standardised designs and application methodology. They can access open water sources by either drafting (when in close proximity to the water) or using floating source pumps (for variable level or difficult access water sources). Mobile fire apparatus is generally more cost-effective to procure when using standardized designs and application methodology With this open water access, they can provide significantly more water (upwards of 10,000 GPM or more per system if necessary) than any typical fixed fire pumping solution. Moreover, as their primary benefit, they are easy to move and deploy. This benefit allows them to be utilised at the point of hazard as needed while being easily accessible for service. While fixed systems are installed at “every known” hazard and must be continually maintained to operate effectively, mobile systems may be used sitewide or across facilities. This flexibility reduces overall capital expenditure requirements and establishes a valuable primary and secondary firefighting system depending on the hazard and facility resources. Combining fixed and mobile systems Permanent installation fire suppression systems are a mainstay of modern day firefighting. They provide immediate passive response with little human intervention. However, as facility utilisation is pushed to maximum capacity while fixed systems continually age out without adequate replacement or maintenance, mobile systems will need to both fill the response gap and provide a final wall to total loss incidents. The reality is that both fixed and mobile systems need to work together to provide the safest possible operation. Service and training requirements need to also be maintained to manage an adequate, or even better, exemplary response to hazard control incidents. Managing major facility uptime requires continuous oversight and to drive hazard mitigation standards throughout the organisation, including executive management. A safe, reliable and fully-functional plant is also a profitable and cost-effective plant much like a healthy worker is a better worker. Protect your people and property and you will protecting your company’s future.
