TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Combustible under specific conditions. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION

EXPOSURE		PREVENT DISPERSION OF DUST!
•INHALATION	Sore throat. Cough. Laboured breathing. Weakness.	Local exhaust or breathing protection.	Fresh air, rest. Half-upright position. Refer for medical attention.
•SKIN	Dry skin. Redness.	Protective gloves.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
•EYES	Redness.	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	Headache. Vomiting. Weakness.	Do not eat, drink, or smoke during work.	Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give plenty of water to drink. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
BLACK POWDER, TURNS GRADUALLY INTO INDIGO-BLUE CRYSTALS OF VANADIUM TETROXIDE (V2O4) ON EXPOSURE TO AIR.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing irritating and toxic fumes (vanadium oxides).

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.

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.

EFFECTS OF SHORT-TERM EXPOSURE:
The aerosol irritates the eyes, the skin and the respiratory tract. Inhalation of high concentrations of aerosol of this substance may cause conjunctivitis, rhinitis and bronchitis. The effects may be delayed. See Notes.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the respiratory tract , resulting in chronic rhinitis and chronic bronchitis.

PHYSICAL
PROPERTIES

DATA

N O T E S

Depending on the degree of exposure, periodic medical examination is indicated. The symptoms of acute exposure do not become manifest until 1-6 days. Also consult ICSC # 0596 Vanadium pentoxide.
