TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Not combustible.		In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION

EXPOSURE		PREVENT DISPERSION OF DUST! STRICT HYGIENE!
Inhalation	Sore throat. Cough. Burning sensation. Shortness of breath. Laboured breathing. Wheezing.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Half-upright position. Refer for medical attention.
Skin	Redness. Burning sensation. Pain.	Protective gloves.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Pain. Redness. Conjunctivitis.	Safety goggles or eye protection in combination with breathing protection if powder.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Abdominal cramps. Diarrhoea. Drowsiness. Nausea. Unconsciousness. Vomiting.	Do not eat, drink, or smoke during work. Wash hands before eating.	Give one or two glasses of water to drink. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Personal protection: P3 filter respirator for toxic particles. Do NOT let this chemical enter the environment.

IMPORTANT DATA

Physical State; Appearance
YELLOW TO RED CRYSTALLINE POWDER OR SOLID IN VARIOUS FORMS.

Chemical dangers
Upon heating, toxic fumes are formed. Reacts with combustible substances.

Occupational exposure limits
TLV: (Respirable dust or fume) 0.05 mg/m³ as TWA; A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2004).
MAK: Carcinogen category: 2; Germ cell mutagen group: 2 (DFG 2006).

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 aerosol of this substance is irritating to the eyes, the skin and the respiratory tract. Inhalation of high concentrations may cause lung oedema, bronchitis, bronchospasm. The effects may be delayed.

Effects of long-term or repeated exposure
Lungs may be affected by inhalation of high concentrations of dust or fumes. The substance may cause greenish-black discolouration of the tongue.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point (decomposes): 1750°C Melting point: 690°C Relative density (water = 1): 3.4 Solubility in water, g/100 ml: 0.8	The substance is harmful to aquatic organisms.

NOTES

Depending on the degree of exposure, periodic medical examination is suggested.
The symptoms of lung oedema 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.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
Card has been partly updated in October 2004 and 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
Card has been partially updated in August 2007: see Ingestion First Aid, Occupational Exposure Limits.
