(DFG 2005). Lungs may be affected by repeated or prolonged exposure to the
dust of this substance. Tumours have been detected in
experimental animals but may not be relevant to humans. Animal
tests show that this substance possibly causes toxicity to human
reproduction or development.
PHYSICAL PROPERTIES
Boiling point: (partially sublimes) 1550/C Solubility in water, g/100 ml at 30/C: 0.0014 (none)
Melting point: (see Notes) 656/C Vapour pressure, Pa at 574/C: 130
Density: 5.2/5.7 g/cm3 (see Notes)
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in crustacea. It is strongly advised that
this substance does not enter the environment.
NOTES
Melting point established under the absence of oxygen.
Density differs with crystalline structure.
Depending on the degree of exposure, periodic medical examination is suggested.
The recommendations on this card do not apply to vapour exposure during the production.
The technical product may contain impurities which alter the health effects; for further information see ICSC 0013 Arsenic.
UN regulation: the special provision SP45 is applicable to the UN number 1549 (Hazard class 6.1 and packaging group III). It means that
antimony sulfides and oxides which contain not more than 0.5 % of arsenic calculated on the total weight are not subject to these
regulations.
Card has been partly updated in October 2005. See sections Occupational Exposure Limits.
