  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible.        In case of fire in the surroundings, use appropriate extinguishing media.   

 PREVENT DISPERSION OF DUST! PREVENT DISPERSION OF DUST! STRICT HYGIENE!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Sore throat. Cough. Burning sensation. Shortness of breath. Laboured breathing. Wheezing.  Use 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.  Wear 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 refer for medical attention. 
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 CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. 

According to UN GHS Criteria

PHYSICAL & CHEMICAL INFORMATION

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

Physical dangers
No data. 

Chemical dangers
Upon heating, toxic fumes are formed. Decomposes on heating. This produces toxic fumes. Reacts with combustible substances. 

Formula: V2O5
Molecular mass: 181.9
Decomposes at 1750°C
Melting point: 690°C
Relative density (water = 1): 3.4
Solubility in water, g/100ml: 0.8  


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The aerosol is irritating to the eyes, skin and respiratory tract. Inhalation of high concentrations may cause lung oedema, bronchitis and bronchospasm. The effects may be delayed. 

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

Effects of long-term or repeated exposure
Repeated or prolonged inhalation of high concentrations of dust or fumes may cause effects on the lungs. The substance may cause a greenish-black discolouration of the tongue. 


Occupational exposure limits
TLV: (inhalable fraction): 0.05 mg/m3, ppm, as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans).
MAK: carcinogen category: 2; germ cell mutagen group: 2 

ENVIRONMENT
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.
