Use Responsibly
OxyChem is committed to the responsible and efficient use of its calcium chloride products, and also supports our distributors in helping customers who buy and use these products.
Storage & Shelf Life of Solid Calcium Chloride
Store in a dry area, and tightly reseal after each use. To maintain product quality while in storage, solid calcium chloride must be protected from moisture. If the product is on a pallet covered by an intact plastic shroud, it can be stored outdoors on a well-drained surface. If the shroud is torn, pierced, or removed, then the palletized product should be stored indoors or under a waterproof covering.
When properly stored to protect from moisture contact, the expected shelf life for solid calcium chloride products is 36 months. Calcium chloride does not degrade or deteriorate. However, the shelf life is limited based on the potential for moisture intrusion into the product, which may cause product clumping. Solid calcium chloride absorbs moisture from the air (i.e., is hygroscopic), even to the point of converting to liquid brine (i.e., is deliquescent).
For more detailed information see our Calcium Chloride Handbook.
Storage & Shelf Life of Liquid Calcium Chloride
Store in carbon steel tanks with an epoxy-based interior lining and epoxy-based exterior paint. Common stainless steels should not be used for the storage of liquid calcium chloride because they are subject to chloride stress cracking, even at temperatures as low as 100°F (38°C). Nonmetallic materials, such as fiberglass or plastic, may work well for smaller tanks at near ambient temperature. The puncture resistance and structural strength of these materials, relative to carbon steel, should be evaluated.
When properly stored to protect from moisture contact and maintained above crystallization temperature, the expected shelf life for liquid calcium chloride products is 36 months. Calcium chloride does not degrade or deteriorate; however, the shelf life is limited based on the potential for moisture intrusion into the product. Moisture intrusion will cause a decrease in overall calcium chloride concentration.

Melting Ice - Roadways
Responsible use of calcium chloride can improve the effectiveness of road and highway ice control programs used to keep roads open and safe. Best practices should be followed including using the minimum amounts of calcium chloride necessary to achieve desired results and avoid over-application.
Melting Ice - Sidewalks
Responsible use of ice melters is essential to protecting the natural environment and the significant investments made by property owners in pavement, landscaping, interior flooring and other facility infrastructure. Best practices should be followed including using the minimum amounts of calcium chloride necessary to achieve desired results and avoid over-application.
