|PHYSICAL & CHEMICAL INFORMATION|
Physical State; Appearance
Formula: C2H3ClO2 / ClCH2COOH
|EXPOSURE & HEALTH EFFECTS|
Routes of exposure
Effects of short-term exposure
Effects of long-term or repeated exposure
|Occupational exposure limits|
|TLV: 0.5 ppm as TWA; (skin); A4 (not classifiable as a human carcinogen)|
|The substance is very toxic to aquatic organisms.|
|After skin contact, immediately rinsing with plenty of water is needed. Alternatively, emergency baths with 3 - 5 % sodium bicarbonate can be used to submerge the exposed skin.
When > 5 % of the skin surface is affected a severe and even a life-threatening intoxication may occur.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Consult a poison information centre or an expert for further information.
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.
Melting point of alpha form = 63°C, beta form = 56.2°C, gamma form = 52.5°C.
