Danger

Toxic if swallowed (H301)
Harmful in contact with skin (H312)
Toxic if inhaled (H331)
Causes severe skin burns and eye damage (H314)
May cause cancer (H350)
Causes damage to organs through prolonged or repeated exposure (H372)
Causes severe damage to the respiratory tract

Comments: Due to the lack of data, classification regarding specific organ toxicity - repeated exposure (H372) was established by analogy to soluble inorganic arsenic compounds.
