2.4.2 Removal of Cured Foam on Skin
FROTHPAK
™
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.
2.4.3 Eye Contact
Avoid ALL contact with eyes. Causes irritation. If contact with eyes
occurs, flush with clean, low pressure water for 15 minutes while
holding eyelids open. Seek medical attention.
2.4.4 Ingestion
If swallowed, give large amounts of liquids. DO NOT induce
vomiting. Seek medical attention.
2.4.5 Inhalation
Remove to fresh air. If not breathing, give artificial respiration.
If breathing is difficult, oxygen should be administered by a quali-
fied professional. Call a physician or transport to a medical facility.
2.5 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.
2.6 Chemical Information
For more specific information about the chemical components
“A” and “B”, refer to the appropriate SDS. KEEP OUT OF REACH
OF CHILDREN.
2.7 Chemical Spills
Consult SDS section 6 for Accidental Release Measures.
2.7.1 “A” Chemical, ISO
If “A” liquid spills from the tank, hose, or INSTAFLO™ 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.

use-spray-polyurethane-foam-spf-insulation.
• During application a minimum of 10 Air Changes per Hour (ACH) is
required. Cross ventilation is recommended with negative pressure
in the spray area and exhaust to a secured empty area. A commercial
ventilation unit is recommended.
• Continue to ventilate area for at least 1 hour after the job is completed
at no less than 10 ACH.
• Re-entry into an application site occurring less than 1 hour
post spray with proper ventilation requires the use of an approved
air purifying respirator equipped with an organic vapor sorbent
and a particle filter.
• Ensure ventilation hose output is in a safe and secure location that will
not be accessible to individuals without proper PPE in a 25 foot radius
and is not near an air intake for a structure.
2.3 Isocyanate Sensitization
Inhalation of vapors or mist at concentrations in excess of permissible
limits may result in an allergic respiration response and the develop-
ment of sensitization. Skin contact with diisocyanates may play a role
in respiratory sensitization. Anyone who has been sensitized in the past
should not operate nor be in close proximity to the operation of these
systems as isocyante concentrations below exposure guidelines may
cause allergic respiratory reactions in individuals who are already sensi-
tized. Individuals who are sensitized cannot become un-sensitized and
should not handle FROTHPAK. Asthma-like symptoms may include
coughing, difficulty breathing, and a feeling of tightness in the chest.
In rare instances, breathing difficulties may be life-threatening.
2.4 First Aid
It is important to know the proper steps in first aid if there is any type of
contact with two-component, low-pressure foams. In severe cases con-
tact a physician, dial 911, and/or transport them to a medical
facility immediately.
2.4.1 Skin Contact
Avoid ALL contact with skin. May cause irritation or sensitization.
If skin contact occurs, remove contaminated clothing; carefully
remove uncured material without spreading; wash skin with soap
and water. If irritation occurs or persists, seek medical attention.
