introduction
The FROTH-PaK ™ Refill System is a polyurethane foam
dispensing system for users who require large quantities of
foam . The system consists of “a” and “B” chemical tanks,
chemical filters, a high pressure regulator, nitrogen lines,
chemical dispensing hoses, and a Gun/Hose assembly Kit .
The system requires dry nitrogen for chemical tank pressuriza-
tion and is not supplied .
The FROTH-PaK™ Refill System is designed for
ease-of-use . The following instructions should be followed
strictly to ensure maximum equipment performance
and efficiency .

application guidelines as provided by Dow Building Solutions should
be followed exactly in order to ensure compliance with building codes
and worker safety regulations . Read all information bulletins, (Material)
Safety Data Sheets ((M)SDS) and “Product Information” sheets . The SDS
is available at www .building .dow .com/na/en/literature/index .htm .
application of this product is considered a “low pressure” process . It is
recommended that workers obtain spray foam training . Workers must be
respirator fit tested . Employers must have a documented respiratory and
personal protective equipment (PPE) plan . See Section 2 for further
PPE information .
FROTH-PaK™ Foam Insulation and Sealant contain isocyanate, polyol
and hydroflurocarbon blowing agents . See section 2 for further PPE
information . Do not breathe vapor or spray . use only with supplied air
or an approved air purifying respirator equipped with an organic vapor
sorbent and a particle filter to maintain exposure levels below aCGIH,
OSHa, WEEl or other applicable limits . For situations where the atmo-
spheric levels may exceed the level for which an air purifying respirator
is effective, use a positive-pressure air supplying respirator . The spray
foam applicator, and anyone within 25 feet of the applicator, must use
an approved air purifying respirator equipped with an organic vapor
sorbent and a particle filter at a minimum . If there is ever a doubt as to the
potential limits for worker exposure, Dow always recommends using the
highest level of worker protection . additionally, use barrier tape to mark
the working perimeter and install warning signs .
It is important to ensure that the spray area is well ventilated during
application and one hour after spraying . Ventilation in air Changes
per Hour (aCH):
• During application a minimum of 10 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 for increased ventilation rates .
• 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 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 .
