CHAPTER 4 SPECIFIC DESIGN CRITERIA
4-1
INTRODUCTION.
This chapter identifies the specific design needs for each functional area as outlined in
the space program. Tables 4-1 through 4-29 provide this data in a standard Functional
Data Sheet format.
TABLE 4-1.0. APPARATUS BAY
The Apparatus Bays house the fire protection vehicles. Drive-through bays are preferable. All
Description/
bays must accommodate the latest and largest structural and ARFF vehicles. Each bay of the
Usage
Apparatus Room must include the required support utilities (drops) for vehicles such as
exhaust, compressed air, hot and cold water, lighting, and power.
4.26 m (14 ft.) minimum.
Min. Ceiling Ht.
Walls. Concrete masonry units (CMU). Provide epoxy paints on all wall surfaces.
Floor. Provide a sealed concrete surface. A non-skid, low-maintenance traffic coating may
also be acceptable. Slope floor to trench drains.
Ceiling. Ceiling not required; however, consider finishing exposed structure. Consider
coordinating mechanical, electrical and plumbing components. Note that none of the ceiling
components can be located below minimum ceiling height.
Provide minimum 75-mm- (3-in.-) diameter water service with 62-mm- (2.5-in.-) diameter
Plumbing
National Standard Threads ball-valve outlet to each vehicle. Provide an emergency eye wash
fountain and shower. Provide foot-operated mop sink with mop hanging rack. Provide
standard hot and cold water hose bibb for every two truck bays. Provide floor trench drains
parallel to the centerline of each vehicle. All apparatus room drains should connect to an
approved oil/water separator prior to discharge.
The Apparatus Bay is typically heated. Maintain 20 C (68 F) minimum temperature except in
HVAC
areas with very mild winter conditions. Determine exceptions on a case-by-case basis based on
climatic conditions.
The Services will not air condition the Apparatus Bay except through exceptions. For the
Army, refer to TI-800-1, Design Criteria for the appropriate exceptions. The Air Force will
determine on a case-by-case basis based on climatic conditions how to condition the Apparatus
Bay. In addition to considering climatic conditions, consider the energy costs and sustainability
impacts.
Provide a Fire Apparatus Vehicle Exhaust Removal System (FAVERS) in compliance with
NFPA 1500 to eliminate 100% of vehicle exhaust emissions. A direct vent system that
evacuates vehicle exhaust directly to the outside is the preferred FAVERS. Make-up air should
be distributed so as to minimize drafts and be introduced above apparatus level since diesel
exhaust is heavier than air. In this way, the make-up air flow downward will assist in pushing
the exhaust fumes out the Apparatus bay doors when open.
Provide compressed air system on self-retracting lines at each vehicle bay. Consider providing
a floor radiant heating element at each bay door in colder climates to prevent the door from
freezing to the pavement.
Provide Fire Protection System per Paragraph 3-6.3.
Fire Protection
Provide outlets per code. Locate all outlets at 900 mm (36 in) above finished floor. Provide self-
Power
retracting electric drop cords between vehicles that can reach to either end of the bay. Provide
backup power sized to provide full unobstructed operation capability of the apparatus bays.
Provide power to each retractable bay door.
