本文就如何通過常規手段無法開啟的鋼制卷簾門和折疊式車庫門為隊員開辟進入建筑的通道展開詳細解析。

　　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.

　　鋼制卷簾門 “斜切戰術” 的第三次切割。隨后通過操作開始時制作的受力點將板條拉出。商業場所無疑會讓我們在火災現場面臨艱巨挑戰，這主要是因為企業主為防止盜竊或非法進入，在建筑上加裝了各種鎖具。根據城鎮不同，你會發現大量商業場所安裝了鋼制卷簾門；其他商業場所可能配備大量折疊式車庫門或多種類型的車庫門。盡管住宅很少安裝卷簾門，但車庫門在住宅和商業建筑中都很常見。熟悉火災現場對這類大型門進行破拆的戰術關重要?？梢钥隙ǖ卣f，火災現場破拆車庫門的主要目的是為鋪設水帶到達火源或進行排煙、排火、散熱作業開辟通道。無論出于何種原因，大型門需要隊員開辟更大的開口，而這只能通過良好的鋸切基本功以及對切割位置和方法的充分理解來實現。鋼制卷簾門

　　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.

　　鋼制防盜卷簾門常見于城市地區，主要安裝在商業建筑上。卷簾門主要有三種類型 / 操作方式：無鏈條手動操作型、有鏈條手動操作型和電動操作型（建筑外部設有鑰匙箱，通過按鈕或其他鑰匙控制卷簾門）。處理鋼制卷簾門時，必須根據卷簾門呈現的火災情況評估簡單的進入方式。對于手動操作的卷簾門，通?？梢郧袛噫i具，然后手動或通過鏈條升起卷簾門。對于電動卷簾門，若可能，應嘗試通過外部鑰匙箱或內部按鈕升起卷簾門。有時由于火災情況或機械故障，可能需要切割卷簾門。此時，針對卷簾門的切割方法是 “斜切技術”?；馂那闆r或機械故障可能導致隊員無法打開鋼制卷簾門，此時需要對卷簾門進行切割。以下是進行斜切時需要采取的一系列步驟：制作受力點：在切割前，用哈利根破拆工具的尖鉤插入鎖銷上方的板條，制作受力點。這便于切割后輕松拆除板條。左側或右側垂直切割：在卷簾門盡可能靠左或靠右的位置，從鋸手能夠到的點開始，垂直向下切割底部導軌。中部垂直切割：在卷簾門中部進行垂直切割，大約切割四塊板條，包括受力點位置。對側垂直切割：在卷簾門與次切割相對的另一側（盡可能靠左或靠右），從鋸手能夠到的點開始，垂直向下切割底部導軌。總共進行三次切割：卷簾門兩側各一次長切割，中部一次短切割。拆除板條：將哈利根破拆工具插入受力點，向中部切割方向拆除板條。剩余板條會向上收入卷簾門，下部板條會從軌道中拉出。車庫門

　　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

　　多年來，消防行業針對車庫門有許多不同的 “風格” 切割方法。在評估切割方式時，人們通常會將以下因素作為決定采用何種戰術切割的關鍵因素：哪種切割方式速度快？哪種戰術切割在門上的切割次數少？哪種戰術切割能為作業在門上開辟的開口？這三個問題都很關鍵，任何想要在火災現場有效開展工作的人都應該考慮這些問題。也就是說，“方框切割” 是能兼顧上述三個要點的切割方式之一。多年來，它可能一直是消防行業針對商業和住宅車庫門破拆戰術的主要切割方法。其名稱源于切割順序的結果：車庫門開口呈巨大的方形 -- 基本上是一個方框。方框切割需要三次簡單的切割，所有切割都是在操作人員合理高度進行的直線切割。折疊式車庫門 “方框戰術” 的第二次切割。注意隊員在頭頂上方操作鋸子時如何完全控制鋸子。次垂直切割：從車庫門的遠側（右側或左側）開始切割。在鋸手操作鋸子的高點切入，將鋸子深深插入車庫門面板，垂直向下切割街道 / 人行道或車道。如果人員充足，讓一名隊員用哈利根破拆工具的尖鉤在面板上刺出一個孔，這可為切割完成后隊員拉動面板提供著力點。第二次水平切割：與次切割重疊，沿車庫門寬度水平切割。這也需要將鋸子插入車庫門面板，鋸手在頭頂上方操作鋸子。鋸手在抬起鋸子的高度操作時能舒適地控制鋸子關重要。第三次垂直切割：與第二次切割在車庫門的對側遠側重疊，垂直向下切割街道 / 人行道或車道。在完成第三次切割時，要注意已經在車庫門上切割出一個完整的方形洞口。自然地，門的重量會使切割部分想從剩余的門上向內或向外掉落。這時能用哈利根破拆工具或掛鉤將切割的車庫門部分拉向建筑外部。注意：有些人會從遠側向下街道 / 人行道或車道進行第四次對角線切割，這為隊員拉動面板提供了另一個著力點。預先規劃

　　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

　　鋼制卷簾門的斜切和折疊式車庫門的方框切割都是戰術考量。美國消防行業針對切割卷簾門和車庫門有許多不同的戰術。無論如何，鋸手必須確保選擇的戰術能讓人員快速進入建筑，自身操作難度小，并盡量減少卷簾門或車庫門材料對進出建筑的消防員造成阻礙和可能勾住 / 刺穿水帶的情況。到你負責的首要區域去查看可能遇到的挑戰，并開始與你的隊員討論實戰戰術。

　　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.
