Use

ADI no restricting (FAO/WHO, 2001). LD50 7300 mg/kg (mouse, oral). Corrosive, weaker than lime. GRAS (FDA, 182.1205, 184.1205, 2000). The dust or suspension droplets of calcium hydroxide have a stimulating effect on the mucous membrane, which can cause sneezing and coughing. As alkali, it can also saponify the fat, absorb water from the skin, dissolve protein, as well as stimulate and corrode the organization. Moreover, the inhalation of lime dust may cause pneumonia. The maximum allowable concentration of calcium hydroxide is 5 mg/m3. Once Inhaling dust, people can inhale water vapor, codeine and Judah auning, or paint mustard cream at the chest; when calcium hydroxide coming into the eyes, people should rinse the eyes as soon as possible with the running water and followed by 5% ammonium chloride solution or 0.01% CaNa2-EDTA solution, and then add 0.5% tetracaine solution dropwise. While working, people should wear dustproof fiber work clothes, gloves and dust-proof glasses to protect the respiratory organs, and paint grease ointment to prevent dust inhalation.
