"Aqueous Film Forming Foam (AFFF)" means a fluorinated surfactant with a foam stabilizer which is diluted with water to act as a temporary barrier to exclude air from mixing with the fuel vapor by developing an aqueous film on the fuel surface of some hydrocarbons which is capable of suppressing the generation of fuel vapors.
"Class B fire-fighting foam" means any foam designed to extinguish flammable liquid fires.
"PFAS chemicals" means nonpolymeric perfluoroalkyl and polyfluoroalkyl substances that are a group of man-made chemicals that contain at least two (2) fully fluorinated carbon atoms, excluding gases, and volatile liquids.
"Testing" means calibration testing, conformance testing, or fixed system testing.
"Testing Facility" allows the discharge of foam in a non-emergency situation for the evaluation and calibration of firefighting equipment and foam. This facility may also have the capability to provide some level of needed training for firefighters.
"Fixed Foam System" means a complete installation piped from a central foam station, discharging through fixed discharge devices on the flammable liquid hazard being protected.
Foam proportioning components are permanently installed. The system has been engineered for the hazard and often contains multiple (UL or FM) listed components and foam.
"Foam Training Facility" shall mean to allow the discharge of foam in a nonemergency situation for the training of firefighters and readiness of equipment. This facility may also have the capability to provide some level of needed evaluation and calibration of equipment and foam.
