Safety Precautions

Handling Calcium Chloride requires strict adherence to laboratory and industrial safety protocols. Users must wear appropriate personal protective equipment, including chemical-resistant gloves, safety goggles, and protective clothing to prevent direct contact with skin or mucous membranes. Ensure adequate ventilation and have emergency eyewash stations readily accessible during handling.

Store Calcium Chloride in tightly sealed containers within a cool, dry environment away from incompatible chemical substances. Protect from moisture exposure to prevent premature hydration and potential chemical reactivity. Utilize non-reactive storage containers made of materials like polyethylene or glass that can withstand the compound's hygroscopic nature.

In case of accidental exposure, immediately flush affected areas with copious amounts of water for at least 15 minutes. Remove contaminated clothing and seek medical evaluation if irritation or adverse reactions occur. Keep a comprehensive safety data sheet accessible and train personnel on proper emergency response procedures.
