EXPOSURE
PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!

 •INHALATION
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
 •SKIN MAY BE ABSORBED!
Protective gloves. Protective clothing.
Rinse and then wash skin with water and soap. Refer for medical attention.
 •EYES
Face shield or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION
Do not eat, drink, or smoke during work.
Rinse mouth. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS TO WHITE SOLID IN VARIOUS FORMS.

PHYSICAL DANGERS:


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 SHORT-TERM EXPOSURE:


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.

ENVIRONMENTAL
DATA
Environmental Hazard placard 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.
N O T E S
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.
