On entering the firehouse at the beginning of each tour, the unwritten benchmarksfirefighters出现了要实现的目的：结束与我们开始的数字相同的数字，像家人一样对待每个人，练习我们的玩法等。这些清单因会员而异，但大多数人都在类似的方面。也就是说，每个人的清单上都有一项功能，但并非雄辩地说：“尽量不要看起来很愚蠢。”在紧急场景操作中，有无数方法使自己看起来愚蠢。我们经常看到的一个是，公司在努力进入车辆的引擎盖期间188金博网网址多少操作。
The majority of vehicle fires originate in the engine compartment. This is due to several factors including:
- 这是大多数热量被产生和吸收的区域。
- Electrical wires/conduit travel throughout this compartment.
- Combustible parts such as plastics are used such as covers and batteries.
- 可燃液体在整个发动机中连续运行。

至关重要的是,消防队员获得the engine compartment when responding to and extinguishing vehicle fires. This sounds easy, but this simple action could prove more difficult than expected during certain situations.
当访问发动机舱时，大多数消防员都会攻击主闩锁。请记住，引擎盖闩锁是整个组装中最强，最强化的机构。有许多时间测试且有效的技术可以帮助消防员克服引擎盖闩锁，但是在处理暴露于大热量的发动机舱时，这些技术可能会挑战。大火消耗了发动机隔间，并在消防部门到达之前有时间燃烧后，加热可能会改变引擎盖闩锁组件内的操作。这些不必要的改动可能包括构成闩锁的金属组件的翘曲，引擎盖释放电缆的熔化/翘曲或碰撞造成的损坏（这可能是起火的原因）。
Give this, firefighters should consider alternative techniques to gain access quickly, efficiently, and safely. The main shell of the hood is normally made out of thin sheet metal, usually steel or aluminum. On the center front edge of the hood is the main hood latch assembly. On both side edges of the rear of the hood are hinges/struts. These hinges/struts allow for the hood to be opened while staying attached and articulating upward. Instead of gaining access through the main latch assembly, it may be advantageous to change our location of attack and attack just below the rear hinges/struts.
大多数引擎盖都非常薄。当我们花时间看一下车辆引擎盖的实际轮廓时，我们看到金属在引擎盖的后部非常薄，并且随着前部的前进而变得更厚和弯曲。随着这种弯曲，引擎盖的增厚以保持与车辆的接触。知道引擎盖的后部比正面要薄得多，切穿金属要容易得多。与切开前部的较厚部分相比，在后铰链/支柱下方攻击更容易获得。
The operation of this alternative access to the engine compartment is fairly simple and straightforward. After donning our personal protective equipment, masking up, chocking the vehicle, getting a line in service, attacking the fire, etc., crews can:
- Grab a metal cutting saw off your apparatus (reciprocating type saws will work however a rotary type power saw with a proper metal cutting blade will be of greater value).
2. Position yourself on one side of the vehicle, near the A post (this is where the rear of the hood will terminate and the hinges will be located).
3.确定铰链/支柱的位置，并在心理上标记您将开始切割的区域；（如果存在与铰链相反的撑杆，则始终因罢工而造成的危险）。
4. Cut the top corner of the hood on an approximate 45° angle.
5. Cut all the way through the metal from the point determined at the top of the hood all the way through to the point determined on the side of the hood.
6.确保切口从顶部接缝到侧缝（任何未完全切割的点都会阻碍引擎盖的操作和去除）。
7.移至车辆的另一侧（最好从车辆后面，以最大程度地减少暴露于前保险杠支撑杆，这些支撑物暴露于巨大的热量，爆炸）。
8.将自己放在A柱旁边车辆对面的同一位置。
9.完成步骤3-6。
10. After both cuts are made, simply fold the hood towards and over the front bumper. Access to the engine compartment will be complete.
除了获得机舱quicker and possibly easier compared to traditional methods, there are other advantages to this method. When we decide to access the engine compartment by attacking the main latch, firefighters are placing themselves in the absolute worst possible position as far as safety. As discussed in our previous article, when exposed to heat, vehicles equipped with struts can explode, causing the bumper to violently fly forward or firing projectiles from the front bumper area. By attacking from near the A posts, we are positioning ourselves in a much safer location. Another advantage is once the cuts are completed and the hood is folded over, the hood acts as a cover/shield to the front bumper. If one of our members is not careful or forgets about the danger of the front bumper area, the folded over hood acts as a protection cover, affording a degree of extra safety should the struts explode.
This alternative technique of gaining access to the engine compartment is quick, easy, and relatively safe (most things we perform on the fireground are never 100% safe). This technique does not have to be employed at every vehicle fire but is simply another tool to have in our ever-growing fire service toolbox.
