|FIRE & EXPLOSION||Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion on contact with incompatible substances. See Chemical Dangers.||NO contact with incompatible materials: See Chemical Dangers||Use water in large amounts, carbon dioxide. NO powder, foam. In case of fire: keep drums, etc., cool by spraying with water. NO direct contact of the substance with water.|
|AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!|
|Inhalation||Cough. Sore throat. Burning sensation. Shortness of breath. Laboured breathing.||Use ventilation, local exhaust or breathing protection.||Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention.|
|Skin||Pain. Yellow staining of the skin. Serious skin burns.||Protective gloves. Protective clothing. Apron.||Wear protective gloves when administering first aid. First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer immediately for medical attention .|
|Eyes||Redness. Pain. Severe burns.||Wear face shield or eye protection in combination with breathing protection.||Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.|

|EXPOSURE & HEALTH EFFECTS|
Routes of exposure
Effects of short-term exposure
Effects of long-term or repeated exposure
|OCCUPATIONAL EXPOSURE LIMITS|
TLV: 2 ppm as TWA; 4 ppm as STEL.
EU-OEL: 2.6 mg/m3, 1 ppm as STEL
|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.
IARC considers mists of strong inorganic acid to be carcinogenic (group 1). However there is no information available on the carcinogenicity of other physical forms of this substance. Therefore no classification for carcinogenicity under GHS has been applied.
NEVER pour water into this substance; when dissolving or diluting always add it slowly to the water.
The odour warning when the exposure limit value is exceeded is insufficient.
Rinse contaminated clothing with plenty of water because of fire hazard.
