a safe and secure location that will not be accessible to
individuals without proper PPE, loosely cover, and allow
it to stand at least 24 hours . Dispose of the waste
container in accordance with federal, state, and
local regulations .
2.7.2 "B" Chemical, POLYOL
If the "B" chemical spills from the tank, hose, or
Insta-Flo
Gun, wear all PPE, dike and isolate the spill
™
area . Keep unnecessary and unprotected personnel
from entering the area . Soak up the residue from the
surface with soap and water . Discard in accordance with
federal, state, and local regulations .
2.8 Cautions
2.8.1 Storage Temperature
Recommended storage temperature:
60°–80°F (16°–27°C) . Storage below 60°F (16°C) is not
recommended . Do not store at temperatures above
120°F (49°C) .
2.8.2 Building Codes
In many areas, building codes may restrict the use
of cellular plastics or polyurethane foam in exposed,
interior finishing material applications . Under certain
application code, the use of these materials may be
prohibited . The foam produced by this product is organic
and may constitute a fire hazard if improperly applied .
Consult local building codes .
When air sealing buildings, ensure that combustion
appliances, such as furnaces, water heaters, wood burn-
ing stoves, gas stoves and gas dryers are properly vented
to the outside . See website: http://www . e pa . g ov/iaq/

ventilation .html .
2.8.3 Surface Temperature Restrictions
Polyurethane foam should not be used in direct contact
with chimneys, heat vents, steam pipes, or other surface
areas that exceed 240°F (116°C) . The foam should not be
left exposed or inadequately protected for both interior
and exterior finishing materials . It is strongly recom-
mended in all applications that the foam be protected
by approved facings and coatings .
2.8.4 Open Flame / Spark Source
Do not smoke or operate the system in close proximity
to an open flame or spark source . Ensure pilot lights
8
are off . Welding on or near cured polyurethane foam
requires special precautions . Consult DuPont for
instructions .
2.8.5 Excessive Foam Dispensing
Do not apply excessive thicknesses at one time as this
may result in spontaneous combustion . For thickness
greater than two inches of cured foam, dispense foam
in multiple layers, allowing the heat from foaming to
dissipate between sprayings .
2.8.6 Isocyanate Contamination
Isocyanate and water do not mix, and this can happen
even from the water in the air . The material will solidify
and then the gun and hose will be unusable . The best
thing to do is to take care of the guns and hoses by
using the entire kit within 30 days of opening .
WARNING: Water reacts aggressively with isocyanate
("A" chemical/ISO) . Reactions within a confined space
such as within a hose may present a safety concern .
Even small amounts of water vapor may cause a block-
age or an adverse reaction . Water carried within the
polyol ("B" chemical/POLY) hose to the point where
blending with isocyanate occurs must be avoided .
2.8.7 Confined Space
When preparing a site for spray foam, all considerations
for potential confined spaces must be taken and all
OSHA requirements must be met if applicable .
2.9 Training
DuPont does not recommend use of Froth-Pak
Insulation and Sealant Kits without having completed the
OSHA/CCOHS requirements for respiratory protection (i . e .
routine health exams and fit testing, cartridge change out
schedule, required OSHA/CCOHS documentation), having
completed review of the instructions herein, and having
reviewed the Safe Use and Handling presentations available
