Importance Of Firefighting And Firefighter SCBA

The whole building is on fire and the siren of the firefighters are wailing. Those guys in huge yellow suit came out of the truck and started spilling waters coming from the tank to stop the conflagration from burning the whole structure. Someone entered the building and you let out a grasp as soon as the idea of how they can breathe inside the hot atmosphere struck you. Good thing firefighter SCBA is already at the market.

Firefighters are trained skilled workers responsible for the extinguishing of fire. Their most crucial responsibility aside from dousing the fire with water from the tank in their huge truck, is to save the people from being eaten by the conflagration. They are also responsible in saving the people inside the collapsed structure.

When going inside a burning building, it is already assumed that the air is poisonous and is irrespirable. With the scorching hotness and the presence of inferno everywhere, fire would make it hard to breathe putting those who are inside unconscious. One thing that these skilled individuals never leave when going in the field is wearing these apparatuses.

The basic functions of SCBA are to supply oxygen for normal breathing, remove carbon dioxide produced by the body, and increase the supply during exertion. This needs to be strongly built but should weigh light. They have to be comfortable to wear and at the same time, very liable.

There are two categories of SCBA, the closed circuit and the open circuit. The closed circuit circulates the carbon dioxide that is released from the wearer when he breathes out. Medically pure oxygen is used here to support the breathing of the wearer. The other one is known to be an open circuit which all the breathed out carbon dioxide is transported to the outside atmosphere.

Not only that these firefighters are trained in saving a burning building and the people trapped inside. They are also trained in terms of using the apparatus properly. Take this in mind, when they are not trained in keeping themselves safe, they can not save anything.

Some of the tests that will be performed to make sure that the apparatus will work well, is to perform the negative tests. This means that they have to make sure that the supply air tube will fit to the face mask properly. They have to exhale to the exhalation valve when donning on the apparatus.

Another test that will be performed is the leak test or the positive test. It is done through putting or inserting a finger below the face mask so that a deliberate leak will be created. As soon as it is done, the air flow will be higher that will also improve the oxygen flow.

Those are one of the many tests that will be performed during the training and before the firefighting scene. If one of the tests fail, the best option is to avoid using the failed apparatus. Firefighting may not be that kind of job in the neon lights. However, no one can be saved while being trapped in a devoured structured without these experts in field. So firefighter SCBA has to be worn to ensure that breathing will be supported.
