Health hazards

CAUSES SERIOUS EYE IRRITATION. HARMFUL IF SWALLOWED

Physical hazards

Calcium chloride has an exothermic heat of solution and solid products release a large amount of heat when dissolved in water. Heat is generated when mixed with water or aqueous acid solutions. Calcium chloride is hygroscopic and deliquescent, meaning it is capable of absorbing enough moisture from the air to become liquid. Chlorides in the presence of water and oxygen are associated with the accelerated corrosion of common metals, such as steel, copper and brass. Calcium chloride brines are electrically conductive.

Precautionary statements

Wash hands and exposed skin thoroughly after handling. Do not touch eyes. Do not eat, drink, or smoke when using this product. Wear eye protection. - Disposal • Dispose of contents and container in accordance with applicable local, regional, national, and/or international regulations Physical Hazards of Significance Not Mentioned in GHS Classification • Calcium chloride is hygroscopic and is capable of absorbing moisture from the air to become liquid. Chlorides in the presence of water and oxygen are associated with the accelerated corrosion of common metals, such as steel, copper and brass • Calcium chloride has an exothermic heat of solution and solid products release a large amount of heat when dissolved in water • Calcium chloride brines are electrically conductive. There is a risk of electric shock if energized electrical equipment is handled with hands or fabric gloves that are wet with brine Persistent, Bioaccumulative, and Toxic (PBT) and Very Persistent and Very Bioaccumulative (vPvB) Assessment

Additional information

Good hygiene practices include but are not limited to wearing chemical resistant gloves and eye protection; washing hands and affected skin immediately after handling, before breaks, and at the end of the workday; regularly cleaning work area and clothing; etc. HAZARD CLASSIFICATION GHS: CONTACT HAZARD - EYE Category 2A - Causes serious eye irritation GHS: ACUTE TOXICITY - ORAL Category 4 - Harmful if swallowed UNKNOWN ACUTE TOXICITY Unknown Acute Oral Toxicity 100% of this product consists of ingredient(s) of known acute oral toxicity Unknown Acute Dermal Toxicity 100% of this product consists of ingredient(s) of known acute dermal toxicity Unknown Acute Inhalation Toxicity There is no acute inhalation toxicity data available for this material GHS SYMBOL: Exclamation mark GHS SIGNAL WORD: WARNING GHS HAZARD STATEMENTS GHS - Physical Hazard Statement(s) No GHS physical hazard categories were identified for this product GHS - Health Hazard Statement(s) Harmful if swallowed Causes serious eye irritation GHS - Environmental Hazard Statement(s) No GHS environmental hazards were identified for this product GHS - Precautionary Statement(s) - Prevention Wash hands and exposed skin thoroughly after handling.
