|EC Number: 231-595-7
|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Not combustible.||In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.|
|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||Redness. Pain. Serious skin burns. ON CONTACT WITH LIQUID: FROSTBITE.||Cold-insulating gloves. Protective clothing.||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. Blurred vision. Severe burns. ON CONTACT WITH LIQUID: FROSTBITE.||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.|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Evacuate danger area! Consult an expert! Personal protection: gas-tight chemical protection suit including self-contained breathing apparatus. Ventilation. Remove gas with fine water spray.||

Physical State; Appearance
|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 STEL; A4 (not classifiable as a human carcinogen).
MAK: 3.0 mg/m3, 2 ppm; peak limitation category: I(2); pregnancy risk group: C.
EU-OEL: 8 mg/m3, 5 ppm as TWA; 15 mg/m3, 10 ppm as STEL
|The occupational exposure limit value should not be exceeded during any part of the working exposure.
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.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
Other UN number(s) 2186 (refridgerated liquid) hazard class: 2.3; subsidiary hazard: 8; 1789 (hydrochloric acid) hazard class: 8, pack group II or III.
Aqueous solutions may contain up to 38% hydrogen chloride.
