Boron and Ultra High Strength Steels (UHSS)
“The largest foreseeable hurdle in extrication for the next several years will be the auto industry’s increased use of High Strength Low Alloy (HSLA) and Ultra high Strength (UHSS/Boron)” – Dwayne Bales, University of Illinois School of Fire Science.
These exotic metals present a serious problem for most rescue cutters on the market today. At Genesis Rescue Systems and Howell Rescue, we have recognized the urgent need for more powerful cutters and have responded by not only producing some of the strongest cutters on the market, but testing each of them on the latest Boron/UHSS steel reinforced vehicles in order to assure rescue personnel of reliable performance during real life extrications.
Your choice of rescue tools is a complicated decision. UHSS requires an enormous amount of compression force to cause it to catastrophically crack or shatter. The cutter does not actually cut the UHSS material. UHSS material has very similar properties to that of glass, as it is extremely hard, but very brittle. As you watch a cutter cut UHSS materials, you can see this concept by listening for the “crack” of the UHSS bars as they are cut. The enormous amount of pressure it takes to “crack” the bars is where hydraulic cutters don’t measure up. All except for the full line of Genesis Boron Capable cutters.
NFPA 1936 and NFPA Cut Ratings Explained
LFS and NFPA 1936
Lowest Spreading Force (LSF) will prove to be the most important number when evaluating and comparing spreaders. All spreaders, from all manufacturers increase in power as the arms open. LSF is produced at the beginning of the spread and remains steady until the arms are near the full open position, where the force then rises substantially to the HSF (Highest Spreading Force). Since most spreading operations requiring high spreading force are performed within the first 10 inches of opening, the LSF will be the mot important number to consider. Do not focus on a sales technique the emphasizes HSF!
Usable Spreading Force
This is where most extrications begin! Gaining access by using the spreader to pry the vehicle doors open requires the tips of the spreader to start at their weakest position, or Lowest Spreading Force (LSF). As the spreader opens it gains leverage and the spreading force increases exponentially. The problem is that as the vehicle door begins to separate it actually requires less force to continue to open. Therefore, the most important force when choosing spreaders is actually the NFPA 1936 “LSF” rating number.
More Power Up Front
What does “Power Up Front” mean? It means Genesis spreaders have more power at the beginning of the spread, where you need it most. Genesis Spreaders start at a much higher spreading force than our competition. This is critical when choosing a spreader, because it gives rescue personnel more power when starting the extrication.
Published NFPA Numbers
When choosing rescue tools, NFPA has done much of the work for you. Genesis publishes the NFPA 1936 test results for all our tools, certified by TUV, our third party testing organization, recognized by NFPA. We test all of our equipment which lets our customers compare any of our tools performance against other NFPA certified rescue tools. This practice allows departments to compare rescue tools on and “apples-to-apples” basis.
Maximum Cutting Force
Maximum cutting force is NOT an NFPA number. Why? If you look at the illustrations below, you will see two sets of blades. One set is just about to close completely. The other set has overlapped. maximum cutting force is a calculated force, not a measured force. Therefore maximum cutting force depends on where the blades are when you calculate the force generated. You can calculate the force when the blades just start to close (Example 1), or you can calculate the maximum force when the blades have stopped moving and overlap each other (Example 2). Genesis Rescue chooses to provide end users with a realistic cutting force, as opposed to claiming our tools cut at a maximum force, that is only obtainable after the material has been cut. The NFPA standard realizes this and therefore has developed a real life test that enables them to test tools on an even basis.
Rocker Switch Controls
The rocker switch control on Genesis Rescue Tools allows for greater safety to the operator and patient by allowing control of the tool with only one finger if need be. This gives the user the ability to keep appendages safe while still having total control over the tool. Traditional twist style controllers require that the operator’s entire hand is gripped tightly on the tool, and this puts that hand in danger of being crushed between the surface and tool with no way to release the power of the tool, effectively trapping the appendage.
The Genesis rocker switch control is a variable speed controller. Lightly depressing the button will feather the speed at which the tool opens and closes. The more you depress the button the faster the tool operates.
Fine vs. Gross Muscle Movements
When feathering the power of the tool, the push button control makes use of fine muscle movements in the fingers to control how fast the tool operates. In situation where a patient’s appendage is trapped, this ultimate control can become a tremendous advantage. Traditional “twist” style controllers make use of larger muscles located in the forearm, this can lead to gross muscle movements which can place rescue personnel as a severe disadvantage.
All EForce Genesis Rescue Tools come complete with our rocker switch control. The rocker switch control makes use of fine muscle movements as opposed to gross muscle movements when using standard “twist” controllers. This enables the user to feather the power of the tool, easily repositioning the tool safely for cutting or spreading, and avoiding possible pinching or trapping of the user’s hand.
Forging vs. Machining
We invest greatly in the engineering process of our cutter blades before we ever begin the forging process. This means that our blades have been tested rigorously before we produce the “die” that will hammer out our blades. Unlike machined blades, (machined blades can be redesigned on the fly if the design fails) forged blades require an extensive up-front investment, detailed research and development, and superior overall quality. You can rest assured that from the first to the last cut, Genesis Rescue blades will perform as hard as you do.
At Genesis Rescue Systems we believe the blade of the cutter is the most significant part of the tool. it is for this reason; we use a manufacturing process that produces the strongest, most reliable blade available. This manufacturing process begins above steels recrystallization temperature. When the steel reaches this optimal temperature the forging process can begin. Unlike other metal manufacturing processes, forging produces a work piece with superior strength and durability, all qualities rescue personnel, the Genesis family, and the Howell Rescue System’s family live by.
Why not machined or cast blades?
The forging process produces greater consistency, quality, and hardness of the metal. Casting may be a more economic means of producing blades – a cast will cost 50% less to manufacture than forged blades, but the downside to casting is the material is pured into a mold and this can trap bubbles in the material. Bubbles in the material create weak points in the metal. These weak points can lead to broken blades, which in turn can lead to additional injury on the scene.
Machined cutter blades may be more susceptible to fatigue and stress because machining cuts the steels grain pattern. Cutting the grain pattern can create “stress risers,” these imperfections can cause cracks in the blades causing the blade to break and possibly lead to injury. Forging creates a grain structure oriented to the blade, resulting in optimum strength and resistance to stress and fatigue.
The cutting performance of any cutting blade begins with a sharp edge. it was with this thought; Genesis Rescue Systems set out to engineer and manufacture a solution to degraded cutting performance due to the rounding of the blade edge. Without sacrificing quality we created the NXTgen Blade Insert.
As a manufacturer of rescue tools we must be prepared for any materials rescue personnel encounter on scene. This material in some cases is harder than the material used in the manufacturing of traditional cutter blades, which can lead to blade damage. NXTgen Blade Inserts are manufactured with unique high strength alloys that maintain the tools ability to cut Boron and UHSS without damaging expensive blades. Thus giving our cutters equipped with NXTgen technology an edge on new vehicles safety standards. Not only can these blades perform, but NXTgen blades can be replaced in 2 minutes.
