around a fence or hedgerow, or cut away a bush, <br />the operation will be delayed. Designers should <br />consider the potential growth of nearby bushes or <br />plants. <br />Locations that are likely to be blocked should <br />be avoided. Loading docks, by their nature, are <br />subject to temporary storage and vehicular traffic. <br />Another example of a poor location would be in <br />front of a supermarket or department store where <br />stock or carts may block the FDC at any time <br />(Figure 5.7). This may be a good reason to devi- <br />ate from the "street front" requirement, or to <br />locate the FDC in a column abutting the road <br />(Figure 2.2). Designers should always keep in <br />mind how the building will be used, not just how <br />a particular item will look on the construction <br />plans (devoid of people and equipment). <br />Designers should pay special attention to haz- <br />ardous materials. They should locate FDCs away <br />from fuel tanks, gas meters, or other highly flam- <br />mable or explosive substances or processes <br />(Figures 5.7 and 5.8). <br />The designer should also consider the locations <br />of entrances and exits when locating FDCs. A <br />charged hose line is very rigid and will block an <br />outward-swinging door, or provide a trip hazard for <br />exiting occupants and entering firefighters (Figure <br />5.1). Avoid locating FDCs with their inlets pointed in <br />FIRE S'ERVI'CE. FEATURES O'F.

The breakaway caps make it necessary for a <br />firefighter to swing an axe or other tool to remove these <br />caps. This is an accident waiting to happen that could be <br />avoided through careful design coordination. <br />(Fig. 5.7) FDC in the cart area of a supermarket entryway. The FDC <br />is located where merchandise or shopping carts could easily block it, <br />or a fire in the adjacent propane storage area could restrict its use. <br />
