A float boom for confining material floatable on a liquid surface during
high temperature conditions, comprising: an elongated floatable tube
formed of fluid impervious material; a source of fluid under pressure for
cooling the boom during high temperature conditions; piping connected to
the source of cooling fluid for distributing the cooling fluid over the
length of the boom; and, a protective cover, of a fluid-absorbing
material, mounted over the tube, the cover having peripheral edges adapted
to engage the boom to encase the tube therein, the piping distributing the
cooling fluid over the tube and under the cover to soak the cover over its
length.
