High expansion hanger foam test

This video is a test using high expansion Ansul foam inside an aircraft hangar. It is designed to literally fill the hangar with foam in the event of a fire. I thought I'd save you the time to find it on the internet, so you can watch a copy of the video here...

This type of system is ideal for flammable or combustible fuel – aircraft hangars, flammable liquid storage facilities and loading racks.
