High-expansion foam fights hangar fires

摘要

In September 2008, the Tennessee Air National Guard (TANG) 164th Airlift Wing receivedrnI one of the U.S. military's most advanced aircraft hangar fire suppression systems to date. The hangar fire protection project was led by architect-engineers Frankfurt Short Bruza (FSB), Oklahoma City; sprinkler design specialist Security Fire Protection (SFP), Memphis, Tenn.; and Tyco Fire Suppression & Building Products (FS&BP), Marinette, Wis. The group was able to move from FSB's prototype layout drawings to a fully tested, installed, and approved system under rigorous customer requirements.rnThese requirements included Engineering Technical Letter (ETL02-15) guidelines that encompassed every part of the fire suppression system, from getting water to the high-expansion foam generators, to generating the foam and getting it through the pipes to the aircraft. The system had to cover at least 90% of the floor with overlapping blankets within 1 min beneath the largest military aircrafts in the world.
