EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. 

Inhalation risk
A harmful contamination of the air will be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. 

Effects of long-term or repeated exposure
Animal tests show that this substance possibly causes toxicity to human reproduction or development. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 5 mg/m3, as TWA 

ENVIRONMENT
The substance is harmful to aquatic organisms.
