Superbay Fire Fighting Foam test 7 24 2020

Video of a High Expansion Foam test conducted at a large Hangar to NFPA 409 guidelines. the system has a total of 8 foam systems with a total of 48 Jet-x 27 generators located at 85 feet above the Hangar floor. this video shows half of the systems being tripped the other half were tripped one week ago. The system was installed over a two year period in conjunction with 5 new 4500 gpm pumps and all new wet systems thru out Hangar. The Hangar was originally protected by a protein based system which was un reliable. I would like to dedicate this two a fellow Sprinklerfitter named Dan Studer who recently passed but provided  me with wisdom and guidance thru out this install. H&M Fire Protection out of San Francisco installed the system using UA local 483 fitters.
