EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is corrosive to the eyes and skin. Corrosive on ingestion. The substance is irritating to the respiratory tract. See Notes.

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C.

Effects of long-term or repeated exposure
See Notes.

OCCUPATIONAL EXPOSURE LIMITS
TLV: (inhalable fraction and vapour): 1 ppm as TWA; (DSEN); A3 (confirmed animal carcinogen with unknown relevance to humans)

ENVIRONMENT
The substance is toxic to aquatic organisms.

NOTES
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. Health effects may be similar to those of phenol and related compounds. See ICSC 0070. The recommendations on this Card also apply to 3,4-xylenol (CAS 95-65-8), 2,5-xylenol (CAS 95-87-4), 2,4-xylenol (CAS 105-67-9), 2,3-xylenol (CAS 526-75-0), and 2,6-xylenol (CAS 576-26-1).
