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.
Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give plenty of water to drink. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment (extra personal protection: P2 filter respirator for harmful particles).
Separated from food and feedstuffs.
Do not transport with food and feedstuffs.

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 (OELs):
TLV (respirable dust or fume, as V2O5): 0.05 mg/m3 A4 (TWA) (ACGIH 1996).
MAK: 0.05 mg/m3; (1996).


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 irritates 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 indicated. 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 spray, by a doctor or a person authorized by him/her, should be considered.
