Safety of Hydrated Lime
Properties and Potential Risks: Hydrated lime is corrosive. Its aqueous solution is strongly alkaline, with a pH value ranging from 12 to 13.5. Direct skin contact can cause skin defatting and dryness, leading to symptoms such as redness, swelling, and burns. If it gets into the eyes, it may damage the cornea and conjunctiva, potentially causing vision impairment. Inhalation of its dust can irritate the respiratory mucosa, resulting in coughing, difficulty breathing, and other discomforts.
Safe Operation Guidelines: The risks can be effectively minimized by following safety operation procedures. When handling hydrated lime, it is essential to wear protective equipment, including rubber gloves, safety goggles, dust masks, and protective clothing, to prevent skin and eye contact as well as inhalation of dust. During transportation, handle the packages with care to avoid damage and powder leakage. For storage, place hydrated lime in a cool, dry, and well - ventilated warehouse, keeping it away from fire sources, heat sources, acids, and food chemicals to prevent mixing storage.
