IMPORTANT DATA

Physical State; Appearance
GREEN TO BLACK CRYSTALLINE POWDER

Chemical dangers
Reacts violently with iodine and hydrogen sulfide causing fire and explosion hazard.

Occupational exposure limits
TLV: 0.2 mg/m³ as TWA; A1; (ACGIH 2004).
MAK: Sah; Carcinogen category: 1; (DFG 2004).

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

Effects of short-term exposure
The substance is irritating to the skin.

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation exposure may cause asthma. The substance may have effects on the lungs. This substance is carcinogenic to humans.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Melting point: 1984°C Density: 6.7 g/cm³ Solubility in water: none	The substance is harmful to aquatic organisms.

NOTES

Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance.
The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.
