|EXPOSURE & HEALTH EFFECTS|
Routes of exposure
Effects of short-term exposure
Effects of long-term or repeated exposure
|Occupational exposure limits|
TLV: 20 ppm as TWA; (skin); A4 (not classifiable as a human carcinogen).
MAK: 36 mg/m3, 10 ppm; peak limitation category: I(2); pregnancy risk group: D.
EU-OEL: 36 mg/m3, 10 ppm as TWA; 72 mg/m3, 20 ppm as STEL
|Depending on the degree of exposure, periodic medical examination is suggested.
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered.
