本文就如何通过常规手段无法开启的钢制卷帘门和折叠式车库门为队员开辟进入建筑的通道展开详细解析。

　　This article provides a detailed analysis of how steel rolling shutter doors and folding garage doors, which cannot be opened by conventional means, can open a passage for team members to enter the building.

　　钢制卷帘门 “斜切战术” 的第三次切割。随后通过操作开始时制作的受力点将板条拉出。商业场所无疑会让我们在火灾现场面临艰巨挑战，这主要是因为企业主为防止盗窃或非法进入，在建筑上加装了各种锁具。根据城镇不同，你会发现大量商业场所安装了钢制卷帘门；其他商业场所可能配备大量折叠式车库门或多种类型的车库门。尽管住宅很少安装卷帘门，但车库门在住宅和商业建筑中都很常见。熟悉火灾现场对这类大型门进行破拆的战术关重要。可以肯定地说，火灾现场破拆车库门的主要目的是为铺设水带到达火源或进行排烟、排火、散热作业开辟通道。无论出于何种原因，大型门需要队员开辟更大的开口，而这只能通过良好的锯切基本功以及对切割位置和方法的充分理解来实现。钢制卷帘门

　　The third cutting of the "oblique cutting tactic" for steel rolling shutter doors. Then pull out the Flat noodles through the stress point made at the beginning of the operation. Commercial venues undoubtedly present us with daunting challenges at the scene of a fire, mainly because business owners install various locks on buildings to prevent theft or illegal entry. Depending on the town, you will find that a large number of commercial places have installed steel rolling shutter doors; Other commercial venues may be equipped with a large number of folding garage doors or multiple types of garage doors. Although rolling shutter doors are rarely installed in residential buildings, garage doors are common in both residential and commercial buildings. It is crucial to be familiar with the tactics of breaking and dismantling such large doors at the scene of a fire. It can be said with certainty that the main purpose of breaking down garage doors at the scene of a fire is to open up channels for laying water hoses to reach the fire source or for smoke, fire, and heat dissipation operations. For whatever reason, large doors require team members to open larger openings, which can only be achieved through good sawing skills and a thorough understanding of cutting positions and methods.

　　钢制防盗卷帘门常见于城市地区，主要安装在商业建筑上。卷帘门主要有三种类型 / 操作方式：无链条手动操作型、有链条手动操作型和电动操作型（建筑外部设有钥匙箱，通过按钮或其他钥匙控制卷帘门）。处理钢制卷帘门时，必须根据卷帘门呈现的火灾情况评估简单的进入方式。对于手动操作的卷帘门，通常可以切断锁具，然后手动或通过链条升起卷帘门。对于电动卷帘门，若可能，应尝试通过外部钥匙箱或内部按钮升起卷帘门。有时由于火灾情况或机械故障，可能需要切割卷帘门。此时，针对卷帘门的切割方法是 “斜切技术”。火灾情况或机械故障可能导致队员无法打开钢制卷帘门，此时需要对卷帘门进行切割。以下是进行斜切时需要采取的一系列步骤：制作受力点：在切割前，用哈利根破拆工具的尖钩插入锁销上方的板条，制作受力点。这便于切割后轻松拆除板条。左侧或右侧垂直切割：在卷帘门尽可能靠左或靠右的位置，从锯手能够到的点开始，垂直向下切割底部导轨。中部垂直切割：在卷帘门中部进行垂直切割，大约切割四块板条，包括受力点位置。对侧垂直切割：在卷帘门与次切割相对的另一侧（尽可能靠左或靠右），从锯手能够到的点开始，垂直向下切割底部导轨。总共进行三次切割：卷帘门两侧各一次长切割，中部一次短切割。拆除板条：将哈利根破拆工具插入受力点，向中部切割方向拆除板条。剩余板条会向上收入卷帘门，下部板条会从轨道中拉出。车库门

　　Steel anti-theft rolling shutter doors are commonly found in urban areas and are mainly installed on commercial buildings. There are three main types/operating modes of rolling shutter doors: chainless manual operation type, chainless manual operation type, and electric operation type (there is a safety key box outside the building, which controls the rolling shutter door through buttons or other keys). When dealing with steel rolling shutter doors, the simplest way of entry must be evaluated based on the fire situation presented by the rolling shutter door. For manually operated rolling shutter doors, it is usually possible to cut off the lock and then manually or through a chain lift the rolling shutter door. For electric rolling shutter doors, if possible, try raising the shutter door through an external key box or internal button. Sometimes, due to fire or mechanical failure, it may be necessary to cut the rolling shutter door. At this point, the best cutting method for rolling shutter doors is the "oblique cutting technique". A fire or mechanical malfunction may prevent team members from opening the steel rolling shutter door, in which case it is necessary to cut the rolling shutter door. The following is a series of steps that need to be taken when carrying out oblique cutting: making stress points: before cutting, insert the sharp hook of the Haligan breaking tool into the Flat noodles above the lock pin to make stress points. This makes it easy to remove Flat noodles after cutting. Vertical cutting on the left or right side: Cut vertically downwards from the highest point that the saw operator can reach, starting from the position as close to the left or right as possible to the bottom guide rail of the rolling shutter door. Vertical cutting in the middle: vertical cutting is carried out in the middle of the roller shutter door, about four Flat noodles are cut, including the position of the stress point. Vertical cutting on the opposite side: On the opposite side of the rolling shutter door from the first cutting (as close to the left or right as possible), start from the highest point that the saw operator can reach and cut vertically downwards to the bottom guide rail. Three cuts are made in total: one long cut on each side of the rolling shutter door, and one short cut in the middle. Dismantle Flat noodles: insert the Haligan demolition tool into the stress point and remove the Flat noodles towards the middle cutting direction. The remaining Flat noodles will be pulled up into the rolling shutter door, and the lower Flat noodles will be pulled out from the track. garage door

　　多年来，消防行业针对车库门有许多不同的 “风格” 切割方法。在评估切割方式时，人们通常会将以下因素作为决定采用何种战术切割的关键因素：哪种切割方式速度快？哪种战术切割在门上的切割次数少？哪种战术切割能为作业在门上开辟的开口？这三个问题都很关键，任何想要在火灾现场有效开展工作的人都应该考虑这些问题。也就是说，“方框切割” 是能兼顾上述三个要点的切割方式之一。多年来，它可能一直是消防行业针对商业和住宅车库门破拆战术的主要切割方法。其名称源于切割顺序的结果：车库门开口呈巨大的方形 -- 基本上是一个方框。方框切割需要三次简单的切割，所有切割都是在操作人员合理高度进行的直线切割。折叠式车库门 “方框战术” 的第二次切割。注意队员在头顶上方操作锯子时如何完全控制锯子。次垂直切割：从车库门的远侧（右侧或左侧）开始切割。在锯手操作锯子的高点切入，将锯子深深插入车库门面板，垂直向下切割街道 / 人行道或车道。如果人员充足，让一名队员用哈利根破拆工具的尖钩在面板上刺出一个孔，这可为切割完成后队员拉动面板提供着力点。第二次水平切割：与次切割重叠，沿车库门宽度水平切割。这也需要将锯子插入车库门面板，锯手在头顶上方操作锯子。锯手在抬起锯子的高度操作时能舒适地控制锯子关重要。第三次垂直切割：与第二次切割在车库门的对侧远侧重叠，垂直向下切割街道 / 人行道或车道。在完成第三次切割时，要注意已经在车库门上切割出一个完整的方形洞口。自然地，门的重量会使切割部分想从剩余的门上向内或向外掉落。这时能用哈利根破拆工具或挂钩将切割的车库门部分拉向建筑外部。注意：有些人会从远侧向下街道 / 人行道或车道进行第四次对角线切割，这为队员拉动面板提供了另一个着力点。预先规划

　　For many years, the fire protection industry has had many different "style" cutting methods for garage doors. When evaluating cutting methods, people usually consider the following factors as key factors in deciding which tactical cutting to use: which cutting method is faster? Which tactic has the least number of cuts on the door? Which tactical cutting can open the largest opening on the door for homework? These three issues are all crucial, and anyone who wants to effectively carry out work at a fire scene should consider these issues. That is to say, "box cutting" is one of the best cutting methods that can balance the above three points. For many years, it may have been the main cutting method in the firefighting industry for commercial and residential garage door demolition tactics. Its name comes from the result of the cutting sequence: the garage door opening is a huge square - basically a box. Box cutting requires three simple cuts, all of which are straight cuts made at a reasonable height by the operator. The second cut of the "box tactic" for folding garage doors. Pay attention to how team members can fully control the saw when operating it above their heads. First vertical cutting: It is best to start cutting from the far side (right or left) of the garage door. Cut into the safe high point of the saw operated by the saw operator, deeply insert the saw into the garage door panel, and cut vertically downwards to the street/sidewalk or lane. If there are sufficient personnel, have a team member use the sharp hook of the Haligan demolition tool to pierce a hole in the panel, which can provide a point of force for the team member to pull the panel after cutting is completed. Second horizontal cutting: Overlap with the first cutting and cut horizontally along the width of the garage door. This also requires inserting the saw into the garage door panel, with the saw operator operating the saw above their head. It is crucial for the saw operator to comfortably control the height of the saw when lifting it. Third vertical cutting: Overlap with the second cutting on the far side opposite the garage door and cut vertically downwards to the street/sidewalk or lane. When completing the third cutting, be aware that a complete square hole has already been cut on the garage door. Naturally, the weight of the door will make the cutting part want to fall inward or outward from the remaining door. At this point, it is best to use a Harrigan demolition tool or hook to pull the cut garage door part towards the outside of the building. Note: Some people may make a fourth diagonal cut from the far side down to the street/sidewalk or lane, which provides another point of force for team members to pull the panel. Pre planning

　　钢制卷帘门的斜切和折叠式车库门的方框切割都是战术考量。美国消防行业针对切割卷帘门和车库门有许多不同的战术。无论如何，锯手必须确保选择的战术能让人员快速进入建筑，自身操作难度小，并尽量减少卷帘门或车库门材料对进出建筑的消防员造成阻碍和可能勾住 / 刺穿水带的情况。到你负责的首要区域去查看可能遇到的挑战，并开始与你的队员讨论实战战术。

　　The oblique cutting of steel rolling shutter doors and the box cutting of folding garage doors are both tactical considerations. The US fire industry has many different tactics for cutting rolling shutter doors and garage doors. In any case, the saw operator must ensure that the chosen tactics allow personnel to quickly enter the building, minimize their own operational difficulty, and minimize the obstruction caused by rolling shutter or garage door materials to firefighters entering and exiting the building, as well as the possibility of hooking/puncturing water hoses. Go to your primary area of responsibility to identify potential challenges and begin discussing practical tactics with your team members.
