On the Line: Positioning the Backup Line

大多数消防部门都有一项政策，以确保延长备用线以支持所有火灾的第一击攻击线。该线将加强原始攻击线，如果燃烧的数量增加或原​​始线路遭受压力损失或其他问题。备份线的直径应与第一行的直径至少相同，至少应长度长。在从初始线横向使用备份或正上方使用备份的情况下，较长的长度将被证明是有用的。此外，如果第一个发动机错误判断出伸展，并且在火灾的座位上越来越高，则准备就绪的线路将有所帮助。

影响第一引擎和第一辆卡车的一个常见问题是随后的发动机公司的备用线位置。作为面向行动的人，火场上的每位消防员都希望尽可能靠近火。但是，当分配备用线时，消防员必须记住他们的主要功能是准备进入消防，而不是阻碍它。

通常，备份线被拉伸并固定在攻击线上，甚至更糟地延伸到攻击线。尽管这可能会使备用公司更接近大火所在地，但在战斗中的关键点也可能导致不必要的瓶颈。试图促进攻击线的成员可能会无意中推开并踩踏线，这使得很难前进。额外的消防员也可能在线路中产生纠结。此外，卡车公司的消防员试图越过线路进行搜索并找到大火的座位将有更多的困难试图超越额外的成员，尤其是在狭窄的走廊上。延伸备用线的军官和消防员必须准备将他们的线置于待机位置而不会造成障碍。这可以通过大小和自律来实现。

建筑的布局,我s stretched will aid the company officer in choosing the proper position. The backup line should follow the path of the attack line up to a point where it can be held in place close enough to the fire to be rapidly deployed, yet allowing for free movement of the primary line as well as members conducting searches. In most cases, the line is stretched dry for ease of maneuvering. The officer supervising the line may choose to charge it at any point he feels it necessary. Holding fast before the beginning of a narrow hallway or on a lower stair landing often provides the needed room for other companies to operate. In most occupancies, this distance will allow the members on the backup line to get a feel for conditions without putting them directly in the firefight.

备份线的确切登台点将根据建筑布局和条件而有所不同; the key points for this important position are to stretch the correct diameter and length hose and to position it for effective deployment without competing for space with the attack line or truck members trying to conduct searches. This will also help reduce bottlenecks on stairways and in narrow halls in single and small multidwellings.
