2. HAZARDS IDENTIFICATION
POTENTIAL HEALTH HAZARDS:
INHALATION: Dust may cause irritation of the nose, throat and respiratory tract.
EYES CONTACT : Dust may cause severe eye irritation. May cause corneal injury and conjunctivitis.
SKIN CONTACT: Brief contact is non-irritating to skin. Prolonged contact may cause skin irritation due to abrasion action, even a burn. May cause more severe response if skin is damp or abraded. In the presence of moisture (perspiration, humidity. tears) the dust dissolves to form a solution which may cause burns.
INGESTION: Small amounts swallowed incidentally as a result of normal handling operations are not likely to cause injury. However, swallowing larger amounts causes severe burning and pain in the mouth , throat and abdomen. Vomiting, diarrhea and perforation of the esophagus and stomach may occur.
ENVIRONMENTAL EFFECTS: Calcium chloride is easily dissociated into Ca2+ and Cl- ions in water. Calcium is known as an essential nutrient for higher plants and one of the basicinorganic elements of algae. Calcium strengthens cell walls and plant tissues, reduces toxicity of soluble organic acids, elongating roots. Chloride is also an essential micronutrient for plants and has important roles in he photosynthesis and osmoregulation. The primary cause of the damage to roadside plants is the accumulation of chloride in plant tissues to a toxic level by excess loading of inorganic chloride salts.

4. FIRST AID MEASURES
THE FOLLOWING FIRST AID RECOMMENDATIONS ARE BASED ON ASSUMPTION THAT APPROPRIATE PERSONAL AND INDUSTRIAL HYGIENE PRACTICES ARE FOLLOWED :
IF INHALED : If casualty experiences nausea, headache or dizziness, he should stop work immediately and move to fresh air until symptoms disappear. If breathing is difficult, administer oxygen or artificial respiration, if needed, and GET IMMEDIATE MEDICAL ATTENTION. If respiration or pulse has stopped, have a trained person administer basic life support (artificial respiration, indirect massage of heart, automatic external defibrillator) and CALL FOR EMERGENCY SERVICES IMMEDIATELY.
ON CONTACT WITH EYES : Wash affected eyes with plenty of water for at least 20 minutes. Remove contact lenses, if present, after the first 5 minutes, then continue flushing eyes for at least 15 minutes. If irritation persists, repeat flushing. OBTAIN MEDICAL ATTENTION WITHOUT DELAY, PREFERABLY FROM AN OPHTHALMOLOGIST.
ON SKIN CONTACT : Remove affected clothing and wash contaminated areas thoroughly with soap and water. CALL A PHYSICIAN, if skin irritation persists.
IF INGESTION : If victim is conscious: rinse mouth with water, do not induce vomiting. Give one cup (8 ounces or 240 ml) of water or milk if available and transport to medical facility. Do not give anything by mouth if the person is unconscious. CALL A PHYSICIAN IMMEDIATELY AND TRANSFER THE VICTIM TO HOSPITAL AS SOON AS POSSIBLE.
NOTES TO PHYSICIAN: Due to irritating properties, swallowing may result in burns/ulceration of mouth, stomach and lower gastrointestinal tract with subsequent stricture. Aspiration of vomitus may cause lung injury. Suggest endotracheal / esophageal control if lavage is done. If burn is present, treat as any thermal burn, after decontamination. Medical conditions that may be aggravated by exposure to this product include diseases of the skin, eyes and respiratory tract, preexisting liver and kidney disorders.

11. TOXICOLOGICAL INFORMATION
HEALTH EFFECTS:
MAIN EFFECTS: The product causes buns of eyes, skin and mucous membranes. The seriousness of the lesions and the prognosis of intoxication depend directly on the concentration and duration of exposure.
ROUTES OF EXPOSURE: Refer also to Section 4 of this MSDS fro routes of exposure and corresponding symptoms
EYES CONTACT : Calcium chloride, as an aerosol, mist or vapor, irritates eyes. Contact causes severe irritation, corneal damage and impairment of vision.
INHALATION : Inhalation will cause severe irritation of nose, throat and lungs. It may also cause burns to the respiratory tract, which can result in shortness of breath, wheezing, choking and chest pain. SKIN CONTACT : The extent of injury depends on the duration of contact. Dermal exposure may cause severe irritation and/or burns characterized by redness and swelling.
INGESTION : Ingestion may cause a burning sensation in the mouth, irritation, corrosion / ulceration of the entire gastrointestinal tract, diarrhea, bleeding, abdominal pain and vomiting. Asphyxia can occur.
CHRONIC EFFECTS FROM LONG-TERM EXPOSURE :
INHALATION: Chronic (repeated) inhalation exposure may cause cough, running nose, bronchopneumonia, pulmonary edema (fluid build-up) and reduction of pulmonary function. During long-term exposure calcium accumulates in the organism, milk-alkali syndrome develops and conjunctivitis occurs.
EYES CONTACT: After several days of exposure, ulceration and corneal opacification may come, which leads to blindness.
SKIN CONTACT: Permanent skin exposure causes scab formation. Prolonged, confined (especially under the finger nails, under rings or watch bands) or repeated exposure may cause skin irritation and possibly lead to chemical burns.
INGESTION: There may be corrosion of the lips, mouth, tongue and pharynx, bleeding from the mouth or nose. Perforation of the alimentary tract and constrictive scarring may result. Oesophageal stricture may occur week, months or even years later to possibly make swallowing difficult. The estimated fatal dose for men is 5 grams.

12. ECOLOGICAL INFORMATION
ACUTE ANIMAL TOXICITY DATA:
ORAL TOXICITY: is low for animals, due to the severe irritating property of the original substance or its high-concentration solutions to the gastrointestinal tract: LD50 (Rat): 3798 - 4179 mg/kg LD50 (Mice): 1940 - 2045 mg/kg LD50 (Rabbit): 500 - 1000 mg/kg is rare in humans, because large single doses induce nausea and vomiting
DERMAL TOXICITY: LD50 (Rabbit): > 5000 mg/kg
SKIN IRRITATION: Rabbit: Slightly irritating
EYE IRRITATION: Rabbit: Irritating
ACUATIC TOXICITY: Product is practically non-toxic to aquatic organisms on an acute basis: LC50 > 100 mg/l in the most sensitive species tested.
FISH ACUTE TOXICITY: LC50 (Bluegill) : 8350 - 10650 mg/l
LC50 (Pimephales promelas) : 4630 mg/l @ 96 hrs
LC50 (Gambusia affinis): 13400 mg/l @ 96 hrs
CRUSTACEANS ACUTE TOXICITY: EC50 (Daphnia magna): 1062 mg/l @ 48 hrs (immobilization)

TOXICITY TO MICRO-ORGANISMS: EC50 (Activated sludge, respiration inhibition) > 1,000 mg/l CHRONIC ACUATIC TOXICITY: more than 100 mg/L: EC16 (Daphnia magna): 330 mg/l
MOBILITY : The high water solubility (745 g/l @ 20oC / 68oF) indicates that in environment Calcium Chloride will be found predominantly in water. In water (including soil or sediment pore water), the product exists as the Calcium ion (Ca2+) and chloride ion (Cl-) dissociated in water.
AIR : Chemical degradation
WATER : Considerable solubility and mobility.
SOIL / SEDIMENTS: The Calcium ion in soil may bind to soil particulate or may form stable inorganic salts with sulphate and carbonate ions. The Chloride ion is mobile in soil and eventually drains into surface water because it is readily dissolved in water.
PERSISTENCE AND DEGRABILITY :
ABIOTIC DEGRADATION:
AIR : No data
ATMOSPHERIC HALF-LIFE: No data
WATER: Neutralization
SOIL: Ionization / neutralization
BIODEGRADATION : The methods for determining the biological degradability are not applicable to inorganic substances.
BIOACCUMULATIVE POTENTIAL : Bioaccumulation in organisms is not relevant for Calcium chloride.
RESULTS OF PBT ASSESMENT: This product is not considered as PBT or vPvB substance.
PERSISTENCE: Calcium Chloride rapidly dissociates in water. Therefore it does not fulfill the
ACCORDING TO ANNEX II OF EC REGULATION 1907/2006 DD. 18.12.2006
P criterion.
BIOACCUMULATION: Bioaccumulation in organisms is not relevant for Calcium Chloride solution, therefore, this product does not meet the B criterion of the PBT criteria.
TOXICITY: Calcium Chloride does not meet the T criterion in the PBT assessment.
13. DISPOSAL CONSIDERATIONS
SAFE HANDLING OF RESIDUES:: Product waste must follow applicable federal, state and local regulations. For unused or uncontaminated product, the preferred options include either sending to a licensed, permitted recycler / incineration or other thermal destruction device or industrial landfill or dilution with plenty of water or neutralization with acid before discharge.
PACKING DISPOSAL : Empty containers and clean them with water. Dispose of an unused product. The empty and clean containers are to be reused in conformity with regulations.
