Description
GREAT STUFF
™
Insulating Foam Sealant is a polyurethane
plastic foam sold in aerosol cans. Once the foam is
sprayed from the can, it immediately begins to cure
and dry into a hard plastic. It sticks permanently
to most surfaces. The wet chemical in the foam is
isocyanate, which is hazardous. The blowing agent
is highly fl ammable.
Instructions
1. KEEP AWAY FROM CHILDREN.
GREAT STUFF
™
Insulating Foam Sealants
contain dangerous chemicals and should not be
used by or around children.
2. Shut off all sources of ignition or open fl ames during use,
including pilot lights on stoves, dryers, furnaces and water
heaters, candles, cigarettes and electrical devices. Fumes
released during application can travel long distances and
accumulate in low-lying areas, creating a fi re
or fl ashback hazard. Open fl ames in adjacent
rooms behind neighboring walls should also
be shut off. Keep the area free from all sources
of ignition until all fumes have dissipated.
3. Provide plenty of fresh air or ventilation. Open windows
and doors, and create additional airfl ow as
necessary to disperse fl ammable vapors and
prevent the inhalation of isocyanate fumes. If
no ventilation is available and the foam is being
sprayed in a small, confi ned area, wear a NIOSH-
approved respirator equipped with an organic
vapor sorbent and P100 particulate fi lter. Overexposure to
isocyanate can irritate the eyes, nose, throat and lungs. It
may also result in an allergic respiratory response, such as
asthma, or decreased lung function. Overexposure may lead
to permanent sensitization to isocyanate. FIRST AID: Move
to fresh air. If breathing is diffi cult, give oxygen. If
breathing has stopped, give artifi cial respiration. Seek
medical attention.
