Short title	Concentrate and water are proportioned and aerated before foam spreads over liquid fuel.
Image title	Top: water flows through a pipe; a concentrate tank feeds into it at a proportioner (example proportions 1, 3 or 6 percent, product-dependent); at the aspirating nozzle air is drawn in and the solution becomes foam, which is delivered onto a pool. Bottom: cross-section of the pool with a bubbly foam blanket floating on the liquid fuel, a thin draining liquid film beneath the bubbles, with the note that fuel vapour is suppressed.
