 il / fuel soaked vegetation, equipment and
roadways can be rinsed with SuperAll #38, diluted with water (10 - 30
parts water to one part SuperAll #38) to remove the oil / fuel for
easy recovery or dissemination. Often after the contaminant is recovered by
conventional methods (vacuum trucks, sorbents, etc.), remnants of the spilled
material remains as hard to recover residue. SuperAll #38, diluted
with water, is very effective when sprayed on this residue to emulsify and
break-up the hydrocarbon into minute particles that do not recoalesce and can
be readily rinsed away with water.
 uperAll #38, can be applied
using standard fire fighting equipment or any high volume sprayer. A fog
nozzle set at a narrow pattern (0 to 30 deg) is recommended.
 gitation is the key to a rapid and complete
emulsification. Starting at one end of the spill, apply SuperAll #38
over the entire area, working to the opposite side.
il / fuel soaked ground resulting from
fresh or repeated spills can be sprayed and soaked with SuperAll #38
to loosen and emulsify the top soil layers of contaminant. The prediluted
solution of SuperAll #38 and water permeates the top layers of oil /
fuel saturated soil to form a brownish-milky emulsion which, upon this
appearance, should be rinsed thoroughly with water. The brine content, as
well as the contaminated particles, are spread out in suspension by the water
rinse to facilitate rapid biodegradation that eliminates the material, as
well as the SuperAll #38.
 illing of the soil with a standard garden
tiller or tractor drawn disk followed by treating with SuperAll #38
will eliminate any "soaked in" contamination.
 hen gasoline and other fuel oils are
spilled into manhole vaults, ducts, underground sewage and drainage systems, SuperAll
#38 can be employed in a similar manner as an above-ground application.
Blowers can initially be used to evacuate fumes of large concentrations
(registered on an explosion meter). Excessive amounts of hydrocarbon
materials spilled into underground systems may require vacuum trucks to pump
out the bulk contaminants. Otherwise, using standard fire fighting equipment
or similar high pressure system, SuperAll #38 is applied directly with
vigorous agitation down into the surface of the spill with the fog nozzle
adjusted at a narrow setting (0 - 30 deg). Using a 5% solution for fuel oils,
continue application until a substantial build-up of suds appear (a thick,
stable layer). As a rule, for every inch of contaminant on top of water in
manhole, at least an equal volume of the SuperAll #38 / water mixture
should be applied, or until entire surface level of spill is vigorously
agitated. Duct openings and surrounding walls containing the contaminant
should be coarsely sprayed as well.
t this point there is a profound vapor
reduction. The entire mixture should be pumped out in its emulsified state. A
clean water rinse should follow immediately, with nozzle at narrow setting
for continued agitation, to thoroughly remove any residues. After the rinse
is pumped out, the explosion meter reading should register zero. If not, the
entire procedure should be repeated until a zero reading on the explosion
meter is registered. If contamination continues to pour into the manhole from
ducts, then repeat applications. Once accessible, ducts between vaults can be
cleaned of contamination by pumping SuperAll #38 and water in
specified ratios through and on to duct surfaces.
 asily applied, SuperAll #38 provides
a safe and expedient solution to underground spills and causes no harm to
cable coverings, cases, and walls.
