IMPORTANT DATA
Physical State; Appearance WHITE POWDER Occupational exposure limits TLV: (particulate matter containing no asbestos and <1 % crystalline silica) 10 mg/m³ as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004). MAK not established.	Routes of exposure The substance can be absorbed into the body by inhalation. Inhalation risk A nuisance-causing concentration of airborne particles can be reached quickly when dispersed. Effects of short-term exposure May cause mechanical irritation to the eyes and the respiratory tract.
