|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Extremely flammable. Gives off irritating or toxic fumes (or gases) in a fire.||NO open flames, NO sparks and NO smoking.||Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with powder, water spray, foam, carbon dioxide.|
|EXPLOSION||Gas/air mixtures are explosive.||Closed system, ventilation, explosion-proof electrical equipment and lighting.||In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.|
|EXPOSURE||AVOID ALL CONTACT!||IN ALL CASES CONSULT A DOCTOR!|
|Inhalation||Confusion. Drowsiness. Headache. Nausea. Convulsions. Shortness of breath. Unconciousness. Death||Use ventilation, local exhaust or breathing protection.||Fresh air, rest. Half-upright position. No mouth-to-mouth artificial respiration. Administration of oxygen may be needed. Refer for medical attention. See Notes.|
|Skin||MAY BE ABSORBED! Further see Inhalation.||Protective gloves. Protective clothing.||Rinse skin with plenty of water or shower. Refer for medical attention . Wear protective gloves when administering first aid.|
|Eyes||MAY BE ABSORBED! Redness. See Inhalation.||Wear safety goggles or eye protection in combination with breathing protection.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||Burning sensation. Further see Inhalation.||Do not eat, drink, or smoke during work. Wash hands before eating.||Rinse mouth. Do NOT induce vomiting. NO mouth-to-mouth artificial respiration. Administration of oxygen may be needed. Refer for medical attention . See Notes.|
|PACKAGING & LABELLING|
|Evacuate danger area! Consult an expert! Personal protection: gas-tight chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Ventilation. Remove all ignition sources. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. NEVER direct water jet on liquid.||

|The substance is very toxic to aquatic organisms.|
The occupational exposure limit value should not be exceeded during any part of the working exposure.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
The odour warning when the exposure limit value is exceeded is insufficient.
The recommendations on this Card also apply to hydrogen cyanide, stabilized, absorbed in a porous inert material.
Other UN numbers: 1613, Hydrogen cyanide, aqueous solution, not more than 20% of hydrogen cyanide; 1614, Hydrogen cyanide stabilized, absorbed in a porous inert material; 3294, Hydrogen cyanide solution in alcohol, not more than 45% of hydroge
Never work alone in an area if hydrogen cyanide exposure is possible.
Depending on the degree of exposure, periodic medical examination is suggested.
