Medium trucks have lengths between 9.14 and 11.58 m (30 and 38 ft.).
The standardized footprint is 3.05 m by 11.58 m (10 ft. by 38 ft.).
Large ARFF (wide). All ARFF trucks are distinguished by their generally
greater width and may include heavy rescue or very large tankers. Large
ARFF trucks have lengths greater than 11.58 m (38 ft.). The standardized
footprint is 3.66 m by 13.72 m (12 ft. by 50 ft.).
Medium ARFF (wide). Medium ARFF trucks are also distinguished by
their generally greater width. They can vary in length from about 7.01 m
(23 ft.) up to 11.58 m (38 ft.), but the standardized footprint is 3.66 m by
11.58 m (12 ft. by 38 ft.).
Small. These typically include ambulances, small rescue or HAZMAT
trucks, small brush units, and command vehicles. Small trucks have
lengths less than 9.14 m (30 ft.). A separate vehicle bay size class is not
designated for these trucks. Depending on the actual size of the Small
class truck, it may be housed in its own bay or in a bay with another truck.
For example, two 6.10-m- (20-ft.-) long vehicles may be housed in a Large
bay (either ARFF or not). The interactive worksheet makes a
recommendation for the area of additional Apparatus Bays, as
appropriate, for the quantity of Small vehicles indicated. However, this
area must be carefully reviewed by the planning team to ensure it provides
the correct space, accounting for the actual length of the Small vehicles
anticipated and the space that may be available in other bays.
In addition to the truck footprint, the space program takes into account the space around
the parked truck. This space varies depending on whether the truck is parked next to a
wall or another truck. See Figures C-1.1 through C-1.4 for illustrations of these
variations. The space program uses the middle-sized bay for each truck class to
calculate an "average" sized bay for the given vehicle. Also see Table 4-1.0 for more
information on the Apparatus Bays.
