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.

VANADIUM PENTOXIDE ICSC: 0596
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/m as TWA; A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

INHALATION RISK:
Evaporation at 20C 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): 1750C
Melting point: 690C
Relative density (water = 1): 3.4
Solubility in water, g/100 ml: 0.8
ENVIRONMENTAL DATA
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.
