Warning PHYSICAL APPEARANCE: Fine white powder.
Hazard statements
EYE: Minor transient irritation. Possible caustic burning can occur. SKIN CONTACT: May cause allergic skin reaction in susceptible individuals. Prolonged exposure not likely to cause significant skin irritation. Repeated exposure may cause skin irritation. SKIN ABSORPTION: A single prolonged exposure is not likely to result in the material being absorbed through skin in harmful amounts. INGESTION: Low acute oral toxicity; LD50 (rat) greater than 4000 mg/kg. No hazards anticipated from ingestion incidental to industrial exposure. INHALATION: Vapors are unlikely due to physical properties. Over exposure may produce irritation of the mucous membranes, nose, throat, coughing and shortness of breath. Use NIOSH- approved air purifying or supplied-air respirator where airborne concentrations of crystalline silica (quartz) are expected to exceed exposure limits.

Calcium oxide is caustic to living tissue. Over exposure may cause irritation of the eyes, skin and upper respiratory tract.
Precautionary statements
Use personal protective equipment as required to minimize repeated skin exposure. Wash thoroughly after handling. If skin irritation or rash occurs: Wash with plenty of soap and water and avoid repeated exposure. IF ON SKIN: Wash with plenty of soap and water. IF IN EYES: Rinse cautiously with water for several minutes.
