Formula: C2H6O4S / (CH3O)2SO2
|EXPOSURE & HEALTH EFFECTS|
Routes of exposure
Effects of short-term exposure
Effects of long-term or repeated exposure
|Occupational exposure limits|
TLV: 0.1 ppm as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans).

|The substance is harmful to aquatic organisms.|
|Commercial dimethyl sulfate may contain trace amounts of sulfuric acid.
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.
There is no odour warning even when toxic concentrations are present.
Do NOT take working clothes home.
