Yes Greg I would first get the MSDS.Also find out what codes are in your
client's jurisdiction. If it is the IFC there is a flammable and
combustible chapter which will reference maximum quantities based on
control areas. That can be found in the Hazardous material chapter. I
hope this helps.

Subject: Polyol Storage

We have a client who wants to protect their wood frame pole barn.   The
building is a storage facility for liquid Polyol (used with isocyanate
to create polyurethane).  The Polyol is stored in 55 gallon metal drums
and is also stored in 275 gallon plastic totes that are in 4' square
metal wire baskets.  The plastic totes are made from polyethylene
approximately 1/8" thick.  From what I've been told, the Polyol itself
is non-combustible and doesn't pose much of a hazard.  Based on this, I
was thinking it should be a class 2 commodity (non-combustible liquids
in plastic containers larger than 5 gallons with a wall thickness less
than 1/4").  Does anyone else have more information on this product, or
a different idea of what the commodity class should be?
