CHEMICAL DANGERS:


OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: 0.08 ppm, 0.5 mg/m;
Peak limitation category: II(2);
skin absorption (H); sensitization of skin (Sh);
Pregnancy risk group: D;
(DFG 2006).


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

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is severely irritating to the eyes , the skin , and the respiratory tract . The substance may cause effects on the skin , resulting in depigmentation.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the liver , spleen , thyroid and nervous system , resulting in impaired functions .
