IMPORTANT DATA

Physical State; Appearance
COLOURLESS TO WHITE SOLID IN VARIOUS FORMS.

Chemical dangers
The substance decomposes on heating producing toxic fumes.

Occupational exposure limits
TLV: 0.002 mg/m³ as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2004).
MAK: skin absorption (H); Carcinogen category: 4; Pregnancy risk group: D; (DFG 2004).

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

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

Effects of long-term or repeated exposure
The substance may have effects on the liver and nervous system, resulting in impaired functions of organs and skin lesions. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 323-326°C Melting point: 231°C Density: 1.21 g/cm³ Solubility in water, g/100 ml at 20°C: 0.0000005 Vapour pressure, Pa at 20°C: 0.001 Relative vapour density (air = 1): 9.8 Flash point: 242°C c.c. Octanol/water partition coefficient as log Pow: 5.5-6.2	The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur specifically in plants and in fish. The substance may cause long-term effects in the aquatic environment. This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal.

NOTES

Depending on the degree of exposure, periodic medical examination is suggested.
Do NOT take working clothes home.
Amatin, Anticarie, Bunt-cure, No Bunt 80, Bunt-no-more (Dow chemicals), Co-op-hexa (Bayer chemicals), Sanocide, Snieciotox are trade names.
Card has been partly updated in October 2005. See sections Occupational Exposure Limits, Emergency Response.
