EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its vapour and by ingestion.
Effects of short-term exposure The substance is mildly irritating to the eyes and skin. The vapour is irritating to the respiratory tract. Exposure at high levels could cause lowering of consciousness.
Inhalation risk A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.
Effects of long-term or repeated exposure The substance defats the skin, which may cause dryness or cracking.
OCCUPATIONAL EXPOSURE LIMITS
TLV: 50 ppm as TWA
Explosive limits are unknown in literature, although the substance is combustible and has a flash point < 61°C.
