|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire.||NO contact with flammables.||In case of fire in the surroundings, use appropriate extinguishing media.|
|Inhalation||Cough. Wheezing. Laboured breathing. Symptoms may be delayed. See Notes.||Use ventilation (not if powder), local exhaust or breathing protection.||Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.|
|Skin||Redness. Pain.||Protective gloves. Protective clothing.||First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again.|
|Eyes||Watering of the eyes. Redness. Pain.||Wear face shield 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||Abdominal pain. Diarrhoea. Nausea. Vomiting.||Do not eat, drink, or smoke during work.||Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .|
|PACKAGING & LABELLING|
|Personal protection: filter respirator for inorganic gases and vapours adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Do NOT absorb in saw-dust or other combustible absorbents. Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.||

|This substance may be hazardous to the environment. Special attention should be given to fish.|
The occupational exposure limit value should not be exceeded during any part of the working exposure.
Rinse contaminated clothes (fire hazard) with plenty of water.
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 is therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
The symptoms of asthma 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.
