Part of any size-up is determining how many exposures are present and to what extent you must protect those exposures during a fire fight. Pictured is a detached garage which, upon arrival, was fully involved. Not visible in this picture is a C-side exposure which had already been exposed to much radiant heat by the time the first-arriving engine began to attack the garage fire. The IC almost immediately ordered next-in units to set up a water curtain in the alleyway behind the garage to protect the C-side exposure. In this case, protecting the exposure was an integral component of an offensive attack on the main fire. This isn’t always the case, however.
在许多情况下，防御性攻击需要这些类型的操作，并仔细地将防御性火力控制和进攻线进步进入曝光属性和周围。在上面提到的事件中，公司不必进入裸露的结构。但是，几分钟后，另一个结构的火灾本来可以很好地进行，要求另一个攻击团队进入并保护结构免受进一步扩展。将其他处理方法扩展到曝光中，使用高架流，便携式主流和处理方式操作的外部流将提高您防止火势进展的能力。仔细观察最初的消防建筑物中的崩溃危险区以及对效用危害的观察只是这些操作期间的一些安全问题。
存在各种各样的问题,抑制团队, company officers, and apparatus operators when protecting exposures. Officers must determine to what extent they are going to protect exposures, whether to protect them from the inside or outside, what size handlines to use, where to find the most water to supply those handlines, and so on, while putting the safety of their firefighters at the top of their list. Pump operators have to ensure they have enough water to supply main attack lines, exposure protection lines, water curtains, or aerial apparatus called upon to protect an exposure. Aerial apparatus operators must be in the right place at the right time and out of harm’s way to ensure they can be used effectively to protect exposures.
