Spaces that contain the mechanical “heart” of the building (heating, ventilating, air-conditioning, electric, and plumbing) are not considered as important by building owners as those spaces that earn revenue. As a result, these are often cramped rooms filled with machines, pipes, and ducts, with just enough room for a service technician in street clothes to enter with tools. These spaces are often located on mezzanines, in attics or truss lofts, and on roofs. The mechanical equipment is large, and is often set in place by crane while the building is under construction, before the roof and ceiling are installed, as the means of access to these spaces will not accommodate the physical size of the equipment.

照片3显示了楼梯的节省空间改编，有时称为“船梯”。数十年来，这种类型的楼梯一直在钢和木船中使用了数百年。

Since the equipment in mechanical spaces uses electricity, fuel (gas or combustible liquids), and heat, it is predictable that at some time there may be a fire or other incident requiring an emergency response. Since service personnel work in these spaces, it is predictable that at some time, someone will experience a medical emergency.

照片1中的楼梯提供了易于访问的易于访问，该途径是建筑物占领部分的地板之间常见的。消防和紧急医疗服务（EMS）的访问几乎不受限制。
照片2中的楼梯提供了几乎相同的访问性，除了它是由可燃材料制成的，并且会从环境条件和年龄中更快地恶化。
照片3中的船梯狭窄而陡峭。专为穿着街头服装的人而设计；并且可能很难爬上全个人保护设备（PPE）和携带SCBA，手动工具和霍斯线的消防员。对于设备袋和箱子的EMS人员来说，可能很难进入，并且搬迁患者也很困难。
照片4中的垂直梯子将要求消防员用双手和双脚进行攀爬。并且可能需要上面已经在空间中的某人绳索吊装工具和螺旋线。
照片5中的垂直梯子与照片4中的问题相同。但是，秋季保护笼可能使大多数消防员不可能在完整的PPE和SCBA中攀登。
除了有限的访问之外，这些空间通常没有窗户或其他通风开口可以去除热量和其他燃烧产品。EMS删除患者可能需要技术救援技术，因为有限的访问还意味着有限的出口手段。
预备在这些空间之一中对事件的回应对于保护我们的应急响应人员以及优质的客户服务至关重要。
