How should packages of solid calcium chloride be stored?
|
Solid calcium chloride is both hygroscopic and deliquescent. This
means that the product can absorb moisture from the air, even to
the point of converting to liquid brine. For this reason, protecting
solid calcium chloride from excessive moisture exposure is the primary
requirement to maintain product quality while in storage.
|
Opened packages should be tightly resealed after each use to prevent
caking and liquid brine formation that may result from exposure to humid
air. They should be stored in a dry place, but not in an attic, on shelves
or in any area where the leakage of liquid brine could cause damage.
|
Some types of bags do not seal well if stored standing on end, therefore
unopened packages should be stored lying flat in a dry area.
|
Palletized product covered by an intact plastic shroud may be stored outdoors
on a well-drained asphalt or concrete surface. If the shroud is torn, pierced
or removed, the palletized product should be stored indoors or under a waterproof
covering. Products packaged in boxes, drums or FIBCs are typically not shrouded. Therefore,
these packages should be stored indoors or under a waterproof covering.
|
Solid calcium chloride is temperature-stable under all ambient storage conditions.
