El Jaws of Life\u00ae es un equipo fundamental para los bomberos de todo el mundo. Se utiliza para Abrir coches despu\u00e9s de un accidente<\/a>Liberando a las personas atrapadas. \u00bfPero c\u00f3mo funciona? \u00bfY por qu\u00e9 es tan importante?  <\/p>\n\n\n\n

Firefighters call the first 60 minutes after a traumatic injury the \u201cgolden hour.\u201d Getting a patient out of a crushed vehicle quickly enough to reach surgery within that window dramatically improves survival odds, which is why departments invest in the Jaws of Life\u00ae even if they deploy them only a few times each year. Here\u2019s everything you should know about these incredible tools. <\/p>\n\n\n\n

\u00bfQu\u00e9 son las Mand\u00edbulas de la Vida\u00ae?<\/strong> <\/h2>\n\n\n\n

The Jaws of Life\u00ae are rescue tools used by first responders to free people who are trapped in a vehicle after a crash. There are four main types of tools \u2013 cutters, spreaders, rams, and combination tools \u2013 that are used to cut through or spread apart strong metal or debris. <\/p>\n\n\n\n

Aunque se usan com\u00fanmente despu\u00e9s de accidentes automovil\u00edsticos, estas herramientas tambi\u00e9n se emplean para rescatar a v\u00edctimas de edificios derrumbados tras terremotos u otros desastres naturales. Piense en ellas como herramientas de extracci\u00f3n para rescatar r\u00e1pidamente a personas atrapadas. Vea el video a continuaci\u00f3n para verlas en acci\u00f3n. <\/p>\n\n\n\n

Jaws of Life\u00ae es en realidad un t\u00e9rmino registrado que se refiere a los separadores, cortadores y arietes fabricados por <\/a>Hurst. Otras herramientas de dise\u00f1o similar suelen denominarse equipos de extricaci\u00f3n o herramientas de rescate. <\/p>\n\n\n\n

\u00bfQui\u00e9n invent\u00f3 las Tiburones de la Vida\u00ae?<\/strong> <\/h2>\n\n\n\n

El La idea de estas herramientas empez\u00f3 con George Hurst<\/a>. He wasn\u2019t a firefighter, first responder, or even a safety engineer. In fact, Hurst built incredibly fast and dangerous race cars in the 1950s and 60s. <\/p>\n\n\n\n

One day on the racetrack, Hurst\u00a0witnessed\u00a0a violent crash. He watched rescue crews take over an hour to remove drivers from their cars.\u00a0The experience troubled Hurst, inspiring him to design a tool that could pry open the doors of crashed vehicles<\/a> significantly faster.\u00a0<\/p>\n\n\n\n

His first design in 1961 was a 350-pound hunk of metal that required an entire team of rescuers to use. Over the next decade, he continued improving his design and eventually got the tool down to 65 pounds. This La maravilla de la ingenier\u00eda se llam\u00f3 Hurst Power Tool.<\/a>. Hurst Performance, Inc. remains one of the leading manufacturers of hydraulic rescue tools today. <\/p>\n\n\n\n

As word of Hurst\u2019s invention spread, the National Fire Protection Association developed NFPA 1936, a performance standard that every modern rescue tool must meet before it can be placed on a truck. The standard demanding cut-, spread-, and endurance-tests have driven manufacturers to produce lighter alloys, ergonomically balanced handles, and safer, spark-free blades \u2013 improvements that benefit both rescuers and victims. <\/p>\n\n\n\n

\u00bfDe d\u00f3nde viene el nombre \u201cJaws of Life\u00ae\u201d?<\/strong> <\/h2>\n\n\n\n

Existen diversas opiniones sobre el origen del t\u00e9rmino \u00abJaws of Life\u00ae\u00bb. Sin embargo, la mayor\u00eda cree que fue acu\u00f1ado por otro ingeniero que trabaj\u00f3 en el proyecto, Mike Brick. <\/p>\n\n\n\n

Al ver la rapidez con la que las herramientas pod\u00edan rescatar a alguien de un veh\u00edculo accidentado, Brick empez\u00f3 a llamarlas las Mand\u00edbulas de la Vida\u00ae. \u00bfSu razonamiento? Porque rescataban a la gente de las garras de la muerte. <\/p>\n\n\n\n

\u00bfC\u00f3mo funcionan las herramientas de extricaci\u00f3n?<\/strong> <\/h2>\n\n\n\n

Los equipos de extracci\u00f3n tradicionales funcionan mediante un sistema de pist\u00f3n simple.<\/a> A power source forces hydraulic fluid into the first piston, which then drives down the second piston, applying immense pressure into the tools quickly. This is what allows these tools to produce such extreme force in a relatively small package. <\/p>\n\n\n\n

A medida que la tecnolog\u00eda ha avanzado, las herramientas m\u00e1s nuevas funcionan con bater\u00edas de litio. Esto las hace m\u00e1s ligeras y port\u00e1tiles, ideales para el personal de primera respuesta. <\/p>\n\n\n\n

The Jaws of Life\u00ae can create 120,000 pounds of cutting force and nearly 60,000 pounds of spreading force.<\/a> For perspective, that\u2019s enough power to cut through a 6-inch steel beam or lift 10 elephants off the ground \u2013 all in a matter of seconds. <\/p>\n\n\n\n

\u00bfPara qu\u00e9 est\u00e1n dise\u00f1adas las diferentes herramientas?<\/strong> <\/h2>\n\n\n\n

Cortadores<\/strong> <\/h4>\n\n\n\n

Using immense pressure, cutters slice through metals to remove damaged and dangerous obstructions, allowing openings for firefighters to rescue passengers. <\/p>\n\n\n\n

Esparcidores<\/strong> <\/h4>\n\n\n\n

Like a pair of reversed scissors, spreaders start in a closed position and apply outward force to create a wedge between debris, giving people the space to be removed from the wreckage. <\/p>\n\n\n\n

Carneros<\/strong> <\/h4>\n\n\n\n

Similar to spreaders, rams are used to create space. However, unlike \u201cV\u201d shaped spreaders that are typically limited to 30 inches of width, rams can extend straight out to 60 inches, making them ideal for dislodging sections of a crash that may be pinning someone down and preventing their rescue. <\/p>\n\n\n\n

Combination Tools<\/strong> <\/h4>\n\n\n\n

Estas herramientas vers\u00e1tiles combinan los dise\u00f1os de cortadores y separadores en una sola herramienta para ahorrar tiempo y espacio. <\/p>\n\n\n\n

\u00bfCu\u00e1les son mejores: las herramientas de rescate hidr\u00e1ulicas o las que funcionan con bater\u00eda?<\/strong> <\/h2>\n\n\n\n

Si bien se ha reconocido que las herramientas de rescate m\u00e1s antiguas, accionadas hidr\u00e1ulicamente, han salvado decenas de miles de vidas, los departamentos de bomberos est\u00e1n haciendo la transici\u00f3n a unidades alimentadas por bater\u00eda por tres razones principales: son m\u00e1s livianas, m\u00e1s r\u00e1pidas y m\u00e1s confiables. <\/p>\n\n\n\n

While significantly lighter than the first 350-pound design, hydraulic rescue tools are still incredibly heavy, weighing in around 65 pounds. Battery operated versions weigh closer to 30 pounds, making them much easier for first responders to operate and maneuver. <\/p>\n\n\n\n

Battery operated tools can cut through a steel beam in just two minutes \u2013 half the time it would take a hydraulic model. Lithium batteries are not only more powerful, but they also last longer. <\/p>\n\n\n\n

Most importantly, battery-operated rescue tools are significantly more reliable. Hydraulic models require a significant number of pieces to operate: a generator to power the tool, gas to run the generator, multiple hoses for hydraulic fluid, and additional attachments. <\/p>\n\n\n\n

If any part of the hydraulic system fails, the entire tool is rendered useless. Battery operated versions, on the other hand, require only a single battery, which can be switched out quickly. Additionally, lithium batteries are not as susceptible to failure in cold weather as hydraulic pumps. This makes them much more reliable in high-pressure situations. <\/p>\n\n\n\n

\u00bfCuanto cuesta el equipo de extricaci\u00f3n?<\/strong> <\/h2>\n\n\n\n

Extrication equipment can cost anywhere from $1,000 for older, hydraulic tools to $40,000 for state of the art battery powered tools. The price depends on the model and the features it offers. <\/p>\n\n\n\n

Typically, for a full set of battery-operated tools (a cutter, spreader, and ram), the cost is around $30,000. <\/p>\n\n\n\n

In many cases, the high cost of newer, battery powered tools means that they are only available to larger fire departments with higher funding. This puts smaller departments and their communities at a significant disadvantage. <\/p>\n\n\n\n

Because the tools are such a major investment, departments schedule quarterly pressure-tests, blade inspections, and battery-cycle counts to ensure every unit is mission-ready. Crews also run full-speed extrication drills during downtime, building the muscle memory needed to position, anchor, and operate the Jaws of Life\u00ae safely when adrenaline is running high. <\/p>\n\n\n\n

\u00bfA cu\u00e1ntas personas salva Tiburones de Vida?<\/strong> <\/h2>\n\n\n\n

Se ha estimado que since their invention, Jaws of Life\u00ae tools have saved over 24,000 lives across the world<\/a>. That\u2019s a life saved every single day since 1961. <\/p>\n\n\n\n

Cuando alguien sufre lesiones traum\u00e1ticas, la diferencia entre la vida y la muerte puede ser cuesti\u00f3n de minutos. Contar con herramientas de rescate fiables permite a los bomberos abrir un coche y rescatar a alguien en mucho menos tiempo del que tardar\u00edan sin ellas. Esto significa que las personas lesionadas reciben tratamiento m\u00e9dico vital con mayor rapidez, lo que aumenta dr\u00e1sticamente sus posibilidades de supervivencia. <\/p>\n\n\n\n

While the newer, battery operated models are not yet as widespread as the older, hydraulic versions, it is estimated that they have the potential to save even more lives in the future <\/p>\n\n\n\n

Frequently Asked Questions About the Jaws of Life\u00ae<\/strong> <\/h2>\n\n\n\n

Do firefighters always use the Jaws of Life\u00ae after a car accident?<\/strong> <\/h4>\n\n\n\n

No. Firefighters only use extrication tools when someone is trapped or when the structure of the vehicle prevents safe access to the injured person. If doors open normally or occupants can exit safely, rescuers may not need to use the Jaws of Life\u00ae. However, in severe crashes where metal is crushed or doors are jammed shut, extrication tools allow first responders to create space and safely remove victims. <\/p>\n\n\n\n

Can the Jaws of Life\u00ae cut through any vehicle?<\/strong> <\/h4>\n\n\n\n

Most modern rescue tools are designed to cut through extremely strong metals used in vehicle frames, including reinforced steel. However, newer vehicle designs sometimes include ultra-high-strength materials that require specialized cutting techniques or stronger tools. Firefighters train regularly to understand vehicle construction and determine the safest way to remove trapped occupants. <\/p>\n\n\n\n

How long does it take firefighters to free someone using extrication tools?<\/strong> <\/h4>\n\n\n\n

The time varies depending on the severity of the crash and the condition of the vehicle. In many situations, firefighters can begin creating space within minutes of arriving on the scene. However, complex crashes involving multiple crushed areas or trapped limbs can take longer because rescuers must work carefully to avoid worsening the victim\u2019s injuries. <\/p>\n\n\n\n

Are the Jaws of Life\u00ae used for rescues other than car crashes?<\/strong> <\/h4>\n\n\n\n

Yes. Although they are most commonly associated with car accidents, extrication tools can also be used in other emergencies. Firefighters may use them during building collapses, industrial accidents, train derailments, or natural disasters where debris traps victims and needs to be cut or pried apart. <\/p>\n\n\n\n

What should you do if you are trapped in a vehicle after a crash?<\/strong> <\/h4>\n\n\n\n

If you are conscious and able to move safely, try to stay calm and avoid sudden movements that could worsen injuries. Call 911 if possible and follow the instructions of emergency responders once they arrive. It is often safest to remain still and allow trained rescue personnel to remove you from the vehicle. <\/p>","protected":false},"author":29,"featured_media":3568,"menu_order":0,"template":"","format":"standard","tags":[107],"blog_category":[884],"class_list":{"0":"post-9984","1":"blog","2":"type-blog","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"tag-jawsoflife","8":"blog_category-auto-accident","9":"entry"},"acf":[],"yoast_head":"\nHow
