Physical dangers

Chemical dangers
Decomposes on heating. This produces toxic fumes. Reacts with water. Attacks metals.

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK: Carcinogen category: 1; Skin absorption (H); (DFG 2004).

Routes of exposure
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

Inhalation risk
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.

Effects of short-term exposure
Blistering agent. Lachrymation. The substance is severely irritating to the eyes, skin and respiratory tract. Inhalation may cause lung oedema. See Notes. The effects may be delayed. Medical observation is indicated.

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged inhalation may cause effects on the lungs. The substance may have effects on the eyes. This may result in impaired functions. This substance is carcinogenic to humans.
