EXPOSURE & HEALTH EFFECTS
Routes of exposure Effects of short-term exposure The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the kidneys and calcium balance after ingestion. This may result in impaired functions. Exposure to high concentrations could cause death.	Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. Effects of long-term or repeated exposure The substance may have effects on the kidneys.
