EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is severely irritating to the eyes, skin and respiratory tract. The substance may cause effects on the skin. This may result in depigmentation. 

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

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. This may result in impaired functions. 


OCCUPATIONAL EXPOSURE LIMITS
MAK: 0.5 mg/m3, 0.08 ppm; peak limitation category: II(2); skin absorption (H); sensitization of skin (SH); pregnancy risk group: D 

ENVIRONMENT
The substance is toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish. 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
