Calcium Chloride is sold either as a solid or in liquid solutions. Solid forms of Calcium Chloride are odourless, white to off-white pellets, mini-pellets or flakes, such as meadow Calcium Chloride, Anhydrous Calcium Chloride 94-97% or dew flake Calcium Chloride. solution products of Calcium Chloride, such as liquid Calcium Chloride solution, are odourless, colourless to pale yellow liquids with viscosities that vary with the concentration.
Cacl2, is a common salt. It behaves as a typical ionic halide, and is solid at room temperature. it has several common applications such as brine for refrigeration plants, ice and dust control on roads, and in concrete. It can be produced directly from limestone, but large amounts are also produced as a by-product of the Solvay process. because of its hygroscopic nature, it must be kept in tightly-sealed containers. it is used to turn kelp into a solid.
Because it is strongly hygroscopic, air or other gases may be channelled through a column of Calcium Chloride to remove moisture. in particular, it is usually used to pack drying tubes to exclude atmospheric moisture from a reaction set-up while allowing gases to escape. It cannot, however, be used to dry alkaline gases such as Ammonia because it will form addition products. It can also be added to liquids to remove suspended or dissolved water. The dissolving process is highly exothermic and rapidly produces temperatures of around 60 °C (140 °F).
In this capacity, it is known as a Drying Agent or Desiccant. it is converted to a brine as it absorbs the water or water vapor from the substance to be dried.
SECTION 1: PRODUCT IDENTIFICATION
SECTION 2: INGREDIENTS
SECTION 3: HAZARDS INFORMATION
Irritant. Causes irritation to skin, eyes and respiratory organs. Harmful if inhaled or swallowed.
SECTION 4: RATINGS
SECTION 5: HEALTH EFFECTS
Inhalation
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.
Reactivity: 0 (None)
Ingestion
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.
SECTION 6: FIRST AID MEASURES
Inhalation
Remove source of contamination or move victim to fresh air, give artificial respiration. Give oxygen. Seek medical attention.
Ingestion
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.
SECTION 7: FIRE FIGHTING MEASURES
Not considered to be a fire hazard.
SECTION 8: EXPLOSION
Not considered to be an explosion hazard.
SECTION 9: STABILITY AND REACTIVITY
SECTION 10: 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.
SECTION 11: PHYSICAL AND CHEMICAL PROPERTIES
SECTION 12: ENVIRONMENTAL INFORMATION
Based on the current available information for Calcium Chloride anhydrous, the material will not biodegrade or bioaccumulate.
Environmental Toxicity: The LC50/96-hour values for fish are > 100 mg/l.
SECTION 13: DISPOSAL
Product that cannot be used for recovery or recycling should be managed by an appropriate and approved waste disposal facility. Processing, use or contamination of this product may change the waste management options. Disposal regulations may differ on country / state / region basis. Dispose of container and unused contents in accordance with local requirements.
TRANSPORTING REGULATIONS
Not regulated.
