Calcium Chloride - Typical MSDS

Note: This is a typical MSDS for Calcium Chloride. This document is provided as is and is for information purposes only. Our supplier provides his own MSDS for each grade together with the quote if required.

Country of Origin: China

Product Identification

  • Product name: Calcium Chloride
  • CAS Number: 10043-52-4
  • Molecular Weight: 110.983
  • Chemical Formula: CaCl2


  • Ingredient: Calcium Chloride
  • CAS: 10043-52-4
  • Percent: 77-94%
  • Hazardous: Yes

Hazards Information

  • Irritant. Causes irritation to skin, eyes and respiratory organs. Harmful if inhaled or swallowed.


  • Health: 1 (Slight)
  • Flammability: 0 (None)
  • Reactivity: 0 (None)

Protective Equipment: Goggles, Plastic apron, sleeves and boots
Storage Color Code: Orange (General)

Health Effects

Granular grade material does not have a significant inhalation hazard. Inhalation of dust may cause irritation to the respiratory organs. Symptoms: coughing and shortness of breath.

Low toxicity chemical. Ingestion causes irritation of the mucous membranes due to heat of hydrolysis. Large amounts can cause gastrointestinal problems, nausea, vomiting and abdominal pain.

Skin Contact
Solid calcium chloride might cause mild skin irritation (dry skin). Aqueous solutions or solid in contact with wet skin might cause severe irritation or burns.

Eye Contact
Causes mechanical abrasion or burns from heat of hydrolysis and chloride irritation.

Exposure Limits: Not established
Chronic Exposure: No information found
Aggravation of pre-existing Conditions: No information found

First Aid Measures

Remove source of contamination or move victim to fresh air, give artificial respiration. Give oxygen. Seek medical attention.

Rinse mouth thoroughly with water. If conscious, induce vomiting immediately as directed by medical personnel. If conscious, give 300-500 ml of water.
Seek medical attention.

Skin Contact
Remove contaminated clothing. Flush skin with warm running water. Remove contaminated clothing and shoes.
Seek medical attention.

Eye Contact
Immediately flush the contaminated eyes with water holding the eyelids open. Seek medical attention immediately.

Fire Fighting Measures

  • Not considered to be a fire hazard.


  • Not considered to be an explosion hazard.

Stability and Reactivity

  • Stability: Stable under ordinary conditions. Might absorb moisture from the air and turn into solution if kept in open containers.
  • Hazardous Decomposition Products: When heated to decomposition produces toxic chlorine fumes. In the presence of sulphuric or phosphoric acids might form hydrogen chloride.
  • Hazardous Polymerization: None.
  • Incompatibilities: Methyl vinyl ether, water, zinc, bromine trifluoride, mixtures of lime and boric acid, barium chloride, and 2-furan percarboxylic acid. Metals will corrode in aqueous calcium chloride solutions especially aluminium (alloys) and brass.

Storage and Handling

Store in a tightly closed container in cool, dry and ventilated area. Protect against mechanical damage. Wet calcium chloride and concentrated solutions could corrode steel tanks. When exposed calcium chloride will absorb moisture and form a solution. Containers previously used to store calcium chloride may be hazardous when empty since they contain product residues and leftovers.
