EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID EXPOSURE OF (PREGNANT) WOMEN!

INHALATION Cough. Headache. Nausea. Sore throat. Vomiting.
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
SKIN Redness. Pain. Blisters.
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
EYES Redness. Pain.
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 pain. Diarrhoea. Sore throat. Vomiting. Burning sensation in the stomach (further see Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
ODOURLESS WHITE CRYSTALLINE POWDER.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes (antimony). Reacts under certain circumstances with hydrogen, producing a very poisonous gas (stibine).

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV (as Sb): ppm; 0.5 mg/m3 (as TWA) (ACGIH 1991-1992).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol.

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on dispersion.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. Lungs may be affected by repeated or prolonged exposure to the dust of this substance. The substance may have effects on the lungs. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction.
PHYSICAL
PROPERTIES
 Boiling point: (partially sublimes) 1550°C
Melting point: 656°C (see Notes)°C
Relative density (water = 1): 5.2/5.7 (see Notes) 		Solubility in water, g/100 ml at 30°C: none
Vapour pressure, Pa at 574°C: 130
ENVIRONMENTAL
DATA
 This substance may be hazardous to the environment; special attention should be given to fish. In the food chain important to humans, bioaccumulation takes place, specifically in crustacea.
NOTES
Melting point established under the absence of oxygen. Density differs with crystalline structure. Depending on the degree of exposure, periodic medical examination is indicated. The recommendations on this card do not apply to vapour exposure during the production. Timonox is a trade name.
