EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation.

Effects of short-term exposure
The substance is irritating to the skin. The substance is severely irritating to the eyes.

Inhalation risk

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma.

OCCUPATIONAL EXPOSURE LIMITS
TLV: 0.005 mg/m³ (ceiling value); (SEN). MAK sensitization of respiratory tract (SA)

ENVIRONMENT
