| Uses | 1), used as a desiccant, the production of alcohol, ester, ether and acrylic resin as a dehydrating agent. Calcium chloride aqueous solution is an important refrigerant for chillers and ice making, which can accelerate the hardening of concrete and increase the cold resistance of building mortar, and is an excellent building antifreeze. Used as port fogging agent and road dust collector, fabric fire retardant. Used as a protective agent and refining agent for aluminum and magnesium metallurgy. It is a precipitating agent for the production of lake pigments. Used for deinking waste paper processing. It is a raw material for the production of calcium salts 2), curing agent; Calcium fortifier; Refrigerating refrigerant; Desiccant; Anti-caking agent; Microbial suppressant; Pickling agent; Tissue improvers 3), used as desiccant, road dust collector, fogging agent, fabric fire retardant, food preservative and used in the manufacture of calcium salt 4), used as lubricating oil additive 5), used as an analytical reagent 6), it is mainly used to treat tetany, urticaria, exudative edema, intestinal and ureteral colic, magnesium poisoning caused by decreased blood calcium 7), used in the food industry as calcium fortifying agent, curing agent, chelating agent and desiccant 8), can increase the permeability of bacterial cell wall |

| Emergency treatment | Isolate the contaminated area of leakage and restrict access. Avoid dust, sweep it up carefully, place it in a bag and transfer it to a safe place or transport it to a waste disposal site | |||
| Packaging, storage, transportation | Bag: 25kg/ bag, ton bag: 1 ton/ton bag Closed operation to enhance ventilation. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter dust masks to avoid dust generation. When handling, light loading and unloading should be done to prevent damage to packaging and containers. Store in a cool, ventilated warehouse. Packaging containers must be sealed to protect them from moisture. Store separately from deliquescent items |
