Our self-contained breathing apparatus (SCBA) is one of the most important pieces of equipment that we use daily. It protects us from immediately dangerous to life or health (IDLH) atmospheres and has been considered the key in the advancement of the fire service today. Our SCBA has evolved through the ages; we now have very modern looking SCBAs compared to the first generation SCBAs.
However, we need to be aware of our SCBAs’ limitations and how to overcome them. Our SCBA limits our vision, especially peripheral vision; limits our ability to communicate and hear; adds extra weight on our backs; limits air supply time; and limits our ability to move around with ease.
我们SCBA给身体增加额外的概要,欣ders our ability to move around or through obstacles. In our basic training, we have all been presented with an obstacle that requires us to somehow reduce our profile so that we can pass through it. This technique, called “low profiling,” is now being taught in firefighter survival classes as a way of self-rescue. It has been around well before firefighter survival training started to emerge, and we need to go back to the basics of knowing our equipment and how to use it. Low profiling is one of those techniques that we should all know and practice.
每当我们减少个人资料时，我们都会采取固有的风险。我们通常希望始终保持我们的SCBA。从我们在设备后面的那一刻起，我们通常希望将其保留，直到我们走出结构并脱尾。当我们在IDLH气氛中挖掘我们的SCBA（或部分删除它）时，我们正在增加暴露于潜在糟糕情况的风险。如果此技术未正确执行，我们的SCBA可能会丢失;或者它可能变得纠缠;或者我们可能不会将带子一直延伸或将SCBA放在地板上的洞中，从而失去了供气供应。
All of these listed risks need to be eliminated or managed in such a way so that we reduce the chance of a potentially bad situation. The only way to manage these risks is to become familiar with low profiling so that we are proficient with this execution.
三种方法
There are three methods in which we can reduce our profile. The first is to simply loosen the straps of the SCBA (but keep the SCBA on). By loosening all of the straps (waist strap and shoulder straps), we are allowing the SCBA to move freely on our back. By doing so, we can navigate through any smaller size opening, allowing the SCBA to either move to one side or the other. Once we pass through the opening, we can then retighten the straps and carry on with our mission.
在生存实例中，重新调整带子并不重要;我们希望尽可能快地退出结构。在搜索操作中，谨慎地谨慎地谨慎。如果皮带没有重新推翻，它们可以成为一个纠缠的危险，也可以让SCBA脱落。这会让你减慢，让你无效。
We need to make sure that we are extending the straps all the way open. Many firefighters will only loosen the straps a little. This will still allow you to doff your SCBA or move it to one side, but when it comes time to re-don the SCBA, you will have trouble. Remember, while you are wearing structural firefighting gloves, you will lose some of your dexterity and feel. This will slow you down when trying to re-don the SCBA. If the straps are extended all the way open, you will ensure a quicker and easier time re-donning your SCBA.
The second method involves loosening the straps and doffing just one side of the SCBA. Photo 9 shows the firefighter has moved his SCBA to one side of his body. This profile will allow the firefighter to fit through tighter obstacles. Depending on the size of the firefighter, this may be the preferred method of reducing your profile. This technique requires all straps to be loosened and then you remove one shoulder strap from your body. The shoulder strap that contains your regulator needs to stay on your body; this will protect the regulator from being pulled apart from the face piece.
一旦SCBA在你的身体侧面，你就可以通过并将SCBA与您一起进行操纵。一旦穿过障碍，你就可以才能融入SCBA。当您经历任何类型的障碍时，它很重要。您需要确保存在楼层以维持您的体重。

The third method is the riskier method; this involves removing your SCBA completely and passing it through the obstacle in front of you, then re-don the SCBA afterward. As mentioned before, the straps will need to be fully extended before you remove your SCBA.
In photo 1, the firefighter has an opening only 14 x 14 inches to go through. He has used his tool to sound the floor on the other side of the wall. He now knows that there is a floor complete with no holes in the immediate vicinity.

This is important to check because, as you pass your SCBA through the opening, if there is a hole in the floor that you missed, your SCBA will go for a ride, and so will your face and regulator.
In photo 2, the firefighter is now preparing to remove his SCBA. He is extending his straps fully.

In photo 3, the firefighter now has his SCBA off his back. He is going to be protecting his regulator by holding onto the right shoulder strap.

在照片4中，消防员现在通过他的SCBA穿过开口。

In photo 5, we can see from the other side of the wall how the firefighter’s SCBA is being passed through. He has a firm grip on his right shoulder strap to protect his regulator and to make sure that he does not lose his SCBA.

Notice the tool lying right next to the wall; this is done so that when the firefighter is ready to move on, he can easily locate the tool. Many times, we will throw our tool through the opening and let it fall where it may. This is not what you want to do; this will only allow you to lose your tool and create more of a panic.
在第6张和7的照片中，我们可以看到消防员通过开放。一旦通过，他现在将重新拒绝他的SCBA，如照片8所示。

在照片9和10中，我们可以看到SCBA的另一个例子通过开口。这次消防员没有牢牢抓住他的SCBA。他用双手在它的一侧握着它，把它推到他面前。他在发表楼层吗？他面前有洞吗？如果有的话，他的SCBA肯定会通过开口来落下，没有机会阻止它。确保您在包含稳压器的肩带上牢固握住。在照片9中，我们可以通过仍然在他的身体上看到消防员保护他的监管机构。

The opening that he went through was only 14 x 14 inches. This is a typical opening since stud walls are spaced 16 inches on center, allowing a 14-inch opening between the studs. A good drill to practice is to make this size hole and make everyone go through it at least once. You will be surprised that even the biggest person on your department will fit through using certain techniques such as low profiling. It is also a good confidence builder for each member.
另一种完成墙壁违规或减少您的个人资料的方法是游泳技术，涉及将SCBA保持在背部，（也许）如果需要，并且“游泳”通过开口向后“游泳”。
在照片11中，消防员将他的SCBA气缸放入违规的开口中。

气缸应定位在开口的拐角中，以允许一个臂向上旋转和在消防员后面旋转（如照片12所示）。

Once the firefighter has one arm through the opening, the other arm will also be rotated up and behind him, going through the opening. At this point, the firefighter’s body should be about halfway through the opening. All that is needed now is for the firefighter to use his legs to push himself completely through the opening (as shown in photo 13).

Once the member is through the opening, he is now able to get to the nearest exit point to quickly exit the structure.
