SECTION 211339 - FOAM-WATER SYSTEMS

This new Section specifies fixed, low-expansion, alcohol-resistant, aqueous film-forming foam (AR-AFFF) fire-extinguishing systems for flammable-liquid fires. Foam systems are normally used on, but are not limited to, Class B (flammable-liquid) fires. This Section describes a diaphragm-type pressure proportioning tank, a venturi proportioning device, and added requirements for discharge devices; it may be edited for other foam systems.

This Section is intended to be used with Division 21 Section "Water-Based Fire-Suppression Systems," which provides foam-water solution distribution piping, valves, and valve specialties that comprise a complete foam-water system.

This Section was condensed from full-length Section of same number and title.

Full-length Section includes the following:

AAAF concentrate
Seismic requirements
Steel and brass piping

Supporting documents contain technical information that applies to all MasterSpec libraries. Generally, specific references to the Section Text in the Evaluations refer to full-length Sections.
