Problems
On 17 December 2005 two firefighters from Tübingen, Germany, died inside a burning building when one of the hoses inside the building burst and they were left without extinguishing agent. In the following reconstruction of the tragedy, experts were surprised to find out that CAFS filled hoses are more likely to burst under heat because the foam is unable to cool the hoses sufficiently.
Some fire district engines have experienced that CAFS filled hoses have a higher incidence of clogging and decrease in pressure.

Famous quotes containing the word problems:
“Hats have never at all been one of the vexing problems of my life, but, indifferent as I am, these render me speechless. I should think a well-taught and tasteful American milliner would go mad in England, and eventually hang herself with bolts of green and scarlet ribbon—the favorite colour combination in Liverpool.”
—Willa Cather (1876–1947)
“The problems of society will also be the problems of the predominant language of that society. It is the carrier of its perceptions, its attitudes, and its goals, for through it, the speakers absorb entrenched attitudes. The guilt of English then must be recognized and appreciated before its continued use can be advocated.”
—Njabulo Ndebele (b. 1948)
““What we know, is a point to what we do not know.” Open any recent journal of science, and weigh the problems suggested concerning Light, Heat, Electricity, Magnetism, Physiology, Geology, and judge whether the interest of natural science is likely to be soon exhausted.”
—Ralph Waldo Emerson (1803–1882)
