2.6 Ingestion
If swallowed, give large amounts of liquids. DO NOT induce vomiting.
Seek medical attention.
2.7 Removal of Cured Foam on Skin
FROTHPAK™ foam will adhere to most surfaces and skin. Avoid ALL
skin contact. Wear gloves and protective clothing. Cured foam is
difficult to remove. Cured foam must be mechanically removed or
allowed to wear off in time.
2.8 Overfilling Restricted Spaces
Avoid overfilling restricted spaces. The reaction of these chemicals
causes expansion and may exert enough force to cause an uncontrolled
stream of foam, spraying the work area and possibly the operator.
2.9 Chemical Information
For more specific information about the chemical components
“A” and “B”, refer to the appropriate SDS. KEEP OUT OF REACH
OF CHILDREN.
2.10 Chemical Spills
Consult SDS section 6 for Accidental Release Measures.
2.10.1 “A” Chemical
If “A” liquid spills from the tank, hose, or INSTAFLO™ Gun,
provide proper ventilation, wear all PPE and isolate the spill area.
Keep unnecessary and unprotected personnel from entering the
area. Dike the area and soak up the spill with an oil absorbent
material (vermiculite, sawdust, etc.). Neutralize the spillage area
with a solution of 90% water, 2% dishwashing detergent, and 8%
ammonia. The amount of this solution should be in excess of
the volume of the spill. Allow the mixture to react for at least
10 minutes. Collect in an open top waste container and treat
with additional ammonia solution. Remove the container to 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.
2.10.2 “B” Chemical
If the “B” chemical spills from the tank, hose, or INSTAFLO 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 accor-
dance with federal, state, and local regulations.
2.11 Cautions
2.11.1 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).
2.11.2 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.
2.11.3 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 recommended in all applications that the
foam be protected by approved facings and coatings.
2.11.4 Open Flame / Spark Source
Do not smoke or operate the system in close proximity
to an open flame or spark source. Ensure pilot lights are off.
Welding on or near cured polyurethane foam requires special
precautions. Consult The Dow Chemical Company for instructions.
2.11.5 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.
2.12 Training
It is recommended that product users receive spray foam training.
