The Protection Behind Structural Firefighting Turnout Gear

Structural firefighting personal protective equipment (PPE) has three layers of protection: an outer shell, a moisture barrier, and a thermal liner. Each of those layers uses a different type of fabric to provide the firefighter with a safe envelope in which to work.

Fibers

Bryan Bolden, senior sales and marketing manager for PBI Performance Products, says his company makes fibers that go into the fabrics that are crafted into the various turnout gear layers. "The principle behind the PBI fiber is that it is more flexible, allowing a firefighter to do the job more efficiently and putting less stress on firefighters because of their turnout gear," Bolden says. PBI's latest innovation is the PBI Lightweight Gold system, says Brian Shiels, PBI's senior development engineer. The system uses either PBI Matrix or PBI Max fabrics made by Safety Components or Kombat Flex made by TenCate Protective Fabrics as the outer shell, a Stedair Gold moisture barrier, and a thermal liner of Glide with PBI G2 or TenCate's Quantum4. "The system is about a pound lighter for all the fabrics, but it's more flexible, so there is more perceived comfort for the wearer," he says. "It's also easier to don and doff the gear."

DuPont Protection Technologies makes two fibers often found in turnout outer shells-Nomex® and Kevlar®. Nomex fiber offers inherent flame resistance while contributing toughness and flexibility to outer shell fabrics, says Dennis Mater, DuPont Nomex sales technical leader for apparel in North America. "Nomex fiber thickens and carbonizes when exposed to intense heat from flames," he says. "This action increases the protective barrier between the wearer and the heat source, helping to reduce burn injury and providing valuable time to work or escape."

DuPont Kevlar is one of the toughest fibers available on the market, Mater maintains. "On an equal weight basis, Kevlar fiber is five times stronger than steel," Mater says. "Yet fabrics made with Kevlar fiber can be lightweight, comfortable, inherently flame-resistant, and thermally protective. Kevlar fiber contributes to the overall durability and strength of lightweight turnout gear outer shell fabrics, enhancing strength and protecting the moisture and thermal barriers inside."

Mater points out that while Nomex and Kevlar fibers are used extensively in the layers of firefighter turnout gear, 70 percent of turnout gear's thermal protection comes from the inner components made of Nomex and Kevlar fiber.

Fabrics

Safety Components makes PBI Max, its newest PBI outer shell fabric, according to Guy Lucas, director of marketing, where the technological design gives firefighters the best combination of break-open and thermal protection, the strongest outer shell fabric, comfort, and flexibility. The weight of PBI Max is seven ounces per square yard (osy).

Another Safety Components outer shell fabric made from PBI fiber is PBI Matrix that combines the heat and flame protection with a durable matrix of high-strength 400- or 600-dernier filaments to reduce wear and tear. This results in high-performance flame and break-open protection, increased abrasion resistance, and improved tear resistance, Lucas says. Read more

The Chief's Role in Apparatus Acquisition and Maintenance

RICHARD MARINUCCI

 

As everyone knows, the fire chief is all-knowing and, like Mary Poppins, practically perfect in every way! I am just kidding, but sometimes we chiefs extend our expertise beyond our knowledge and adversely affect outcomes.

Just because you can do something because of your position doesn't mean you should. Sometimes, a chief may have expertise and have to show others how smart he is. This is not to be critical, only to introduce a topic for discussion-that of fire department vehicles and the role a fire chief should play. One of the main jobs of a fire chief is to get the best possible apparatus and equipment for the organization so the firefighters can perform to their capabilities.

The role of the fire chief in the acquisition and maintenance of apparatus can vary from department to department. Larger organizations with more specialized staff may relieve the chief of certain responsibilities while smaller organizations may not have the resources without more involvement from the chief. Regardless, the fire chief should be engaged and aware of the role he plays. Remember that apparatus is a department's biggest cost, with the exception of personnel. The impact on the budget and revenue is significant and requires understanding of the entire apparatus program from apparatus purchasing to retirement.

The chief's degree of involvement can vary from total control to a more hands-off approach. Those individuals who have a deep passion for fire apparatus will most likely take a more involved role, sometimes to the detriment of the organization. They know their position gives them authority, and because of their interest in apparatus they may overextend their control. Conversely, some fire chiefs may take a completely hands-off approach. In almost all cases, somewhere in the middle is the best approach. Chiefs need to find the "sweet spot" regarding their involvement. They need to realize that they have the ultimate accountability but that others in the organization have much to offer if they are allowed to do so.

A good starting point is to assess the talent in your organization and determine who has ability with regard to apparatus. The individuals need some requisite knowledge and an interest in doing the work. It is more than locating a backyard mechanic and turning things over to that person. A single individual or a team of employees may be needed. Some larger organizations can have a dedicated staff, both managerial and mechanical, to perform the various functions. Smaller departments could give an assignment to an interested and capable individual. There are variations of both of these approaches, but the concepts remain the same. In most cases, you should delegate the tasks associated with the acquisition and maintenance of apparatus.

Once a chief opts to become less of a "nuts and bolts" leader regarding apparatus, he must continue to help provide the support and resources those doing the work need. The ultimate goal is success in getting the necessary vehicles to provide the level of service desired. Like for any job, individuals need the appropriate level of job-specific training. This may be easier said than done. There are programs specific to fire apparatus and others more generic in nature. They may not be nearby, so you may need to look around to find the best sources of this training. You may wish to pursue emergency vehicle technician certification for the levels of work expected to be done. In some cases, personnel may not be assigned to the fire department but rather another city department that works with an entire municipality's fleet. Even if this is the case, the fire department must provide the training needed to do the job.

Introduction to Braking Energy

We all know the statistics-we kill ourselves about 15 to 20 times each year by crashing our fire trucks. I'm not going to dwell on this statistic. I think it repeats itself every year like a broken record. The ultimate question is "Why"? What causes us to repeatedly drive off the road, flip our rigs, and eject ourselves into oblivion? There are many different reasons, and all of these reasons are preventable. The purpose of this series of articles is to address these issues and try to explain to drivers, in layman's terms, why fire trucks crash.

Many fire departments require members to take some sort of emergency vehicle operator's course (EVOC) before they can become drivers. These courses are great for new drivers who are trying to learn how to maneuver a rig in tight quarters. Now I don't know about your department, but my department doesn't respond to too many calls in a parking lot that require us to drive through a bunch of traffic cones. Our calls require emergency responses on real roads with real traffic along with lights, sirens, and radios blaring in the background. These factors combine to increase the driver's excitement and often result in a deadening of the senses. Tunnel vision ensues, and the only thing that the apparatus operator can think of is getting to the incident scene fast. Throw in a mutual-aid company coming from another direction, and we all know what happens-the race is on.

So as you can see, while EVOC classes are a great start, they only touch the tip of the iceberg. Often, these basic classes fail to touch on one of the most important topics that an emergency apparatus operator must come to understand: the physics behind a moving vehicle. I liken this to trying to teach an emergency medical technician (EMT) class without teaching anatomy. The EMT student knows how to put on a bandage but doesn't understand why. The goal of these articles is to make apparatus operators understand that no matter how good they think they are or how long they have been driving, at some point Mother Nature will take over and the vehicle will lose control.

Dynamics

Let's start discussing the dynamics behind a moving fire truck. These concepts are based on the same concepts used by crash reconstructionists-the police officers who shut the road down for hours at a time trying to figure out why a motor vehicle crash occurred. The reason I say this is so that you don't put the magazine down and walk away. Remember-if the cops can understand this, so can we!

The first concept an apparatus operator needs to understand is the concept of energy. Think back to high school physics and the often-heard term "kinetic energy." Now before your eyes roll back in your head, forget the term kinetic energy and just think of a bucket full of water. The bucket is the fire truck and the water is the energy. The bigger the bucket (i.e., the bigger the fire truck), the more water it will hold (i.e., the more energy it has). Also, the faster the bucket is traveling (i.e., the faster you drive down the street), the more water (energy) it will hold.

So to bring your fire truck to a stop, you have to get rid of all the energy-or, in other words, dump all the water out of the bucket. If you want to just slow down, you have to get rid of some of the energy-or just dump some of the water out of the bucket. The question is: How do we get rid of this energy?

The most common way we get rid of energy and bring our rig to a stop is to simply apply the brakes. If you remember from high school physics, energy can be neither created or destroyed; it has to go somewhere. Vehicle brakes take the kinetic energy of a moving vehicle and convert it to hea

28th Annual Apparatus Specification and Safety Symposium

By Richard Marinucci

There is no doubt that every fire department and every fire chief desire fire apparatus that is functional, reliable, and as affordable as can realistically be expected.

With the exception of personnel, vehicles are the most expensive items in a fire department budget. As such, it is important for all organizations to learn as much as they can with regard to purchasing and maintaining fire apparatus. This may be easier said than done, since some departments do not have the resources to maximize their preparation for this critical component of their operation. But to save money and get the product they desire, they need to make an investment.

For the past 27 years, the Fire Department Safety Officers Association (FDSOA) has held a symposium to help fire departments and their personnel better prepare for the important job of acquiring and maintaining fire vehicles. The 28th Annual Apparatus Specification and Safety Symposium will be held January 18-20, 2016, in Scottsdale, Arizona. This event has the sole objective of offering detailed insight into the acquisition and maintenance of fire apparatus. It is not a vendor show but a chance to talk to industry leaders with great insight and experience in buying and fixing vehicles, which will help you to maximize efficiency and effectiveness.

Last year, approximately 400 attendees had the chance to listen to more than 30 industry experts present on a variety of topics. Attendees also were exposed to more than 40 vendor displays, where the manufacturers and service companies could explain their product in great detail. In between, networking opportunities were plentiful. This should not be discounted, as the opportunity to talk informally to those in the know really is valuable in terms of not only information being discussed but also growing your network. The contacts you make remain available to you long after the symposium is over.

Seminar topics this year include a variety of subjects covering all aspects of purchasing and maintaining vehicles. You can get tips about drafting specifications for new apparatus and detailed information about various vehicle components. There are other issues to consider as part of a comprehensive program. One such topic is politics. How much of your apparatus program is reliant on the political process in your community? It is significant, so there will be a session on political considerations in apparatus acquisition and maintenance.

A new aspect of the 2016 Symposium is that it will be held immediately prior to the FDSOA Annual Safety Forum. As part of the shared programing, Gordon Graham will deliver the closing keynote address of the Apparatus Symposium. Last year, Graham opened the program and received his usual rave reviews. The message he delivers is applicable to apparatus policies as well as the risk management in all aspects of the fire service.

Hopefully, you are considering attending or sending a representative of your organization (of course you can send more than one!). Visit the FDSOA Web site at http://www.fdsoa.org for more information. You can also call the office at (248) 880-1864. Save the date and set funds aside from your budget to attend this valuable symposium. You will be glad you did. You will definitely learn about things that will save you money in your fleet management and also learn of ways to improve reliability.

RICHARD MARINUCCI is the executive director of the Fire Department Safety Officers Association (FDSOA) and chief of the Northville Township (MI) Fire Department. He retired as chief of the
