Part 43 At the scene of a fire in a three-story, wood-frame dwelling, the engine company is making a push into the attic to cut off the fire extension into this area. For some unknown reason, the attack line goes limp and the engine crew is without water. Due to the high heat, the firefighters...

- It was difficult for the quint apparatus to lay a supply line around several corners without having problems with vehicles and other obstacles. In addition, positioning the unit for use of the aerial ladder offers trade-offs with positioning the unit to operate as an engine company and would ultimately block access for the first-due ladder company.
- The 75-foot aerial device, while sufficient for single-family dwellings and other structures where the unit can be positioned within 25 to 30 feet from the curb line, was inadequate for buildings with greater setbacks and green space around the property.
- While the quint carried 115 feet of ground ladders, this was inadequate to cover all four sides and elevations of the structure.
As a result of this training exercise, the fire department changed the running order for its apparatus and assigned an engine as the first-due unit and had the mutual aid ladder company respond on the initial alarm as the first-due ladder apparatus. This rear-mounted, 100-foot aerial tower carried additional ground ladders and had sufficient horizontal reach to provide adequate scrub area on the building. (Scrub area is defined as that area of the building that can be touched by the basket of a tower ladder or the tip of an aerial device.) Also, you must determine the operational footprint of the apparatus; i.e., how much real estate is going to be needed to properly position and set up the apparatus.
The next installment of "The Apparatus Architect" will discuss the various types of aerial devices and how ground ladder banking can impact the overall design of the apparatus. We will also highlight several fire departments and their ground ladder capabilities on their apparatus.
