HANDLING,
STORAGE and SHIPPING:
Propylene
Glycol USP is a high-purity material which must be handled
with special precautions to avoid contamination.
Under ordinary conditions, mild steel is a satisfactory
material of construction; however, for long term storage
and where iron contamination and color are objectionable,
stainless steel or aluminum vessels are recommended.
For additional information on handling and storage of PG-USP,
please read the Material Safety Data Sheet. Product
is available in barges, lined tank cars and dedicated tank
trucks, and 55-gallon non-returnable drums, 480 pounds net
weight. Certain government regulations may apply at
the time of shipment.
