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.	Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give plenty of water to drink. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
YELLOW TO RED CRYSTALLINE POWDER OR SOLID IN VARIOUS FORMS.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
Upon heating, toxic fumes are formed. Reacts with combustible substances .

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (respirabble dust or fume) 0.05 mg/m³ as TWA; A4; BEI issued; (ACGIH 2004).
MAK: (Respirable fraction) 0.05 mg/m³;
Peak limitation category: II(1);
(DFG 2004).
OSHA PEL: C 0.1 mg V2O5/m³
NIOSH REL*: C 0.05 mg V/m³ 15-minute *Note: The REL applies to all vanadium compounds except

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

Boiling point (decomposes): 1750°C
Melting point: 690°C

Relative density (water = 1): 3.4
Solubility in water, g/100 ml: 0.8

ENVIRONMENTAL
DATA

The substance is harmful to aquatic organisms.

N O T E S

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. See sections Occupational Exposure Limits, EU classification, Emergency Response.
