Guidance on Safe Use
Administrative data
First-aid measures
Skin contact : Wash with soap and water.
Eyes contact : Remove any contact lenses. Flush eyes with plenty of water for at least 15 minutes. Seek medical attention if symptoms persist.
Inhalation : Remove to fresh air, clear out nasal passages. Seek medical attention if symptoms persist.
Ingestion : If large amounts were swallowed, get medical advice. Do not induce vomiting unless directed to do so by medical personnel.
2 Most important symptoms and effects, both acute and delayed
If swallowed in high quantity, can lead to hypertension, increase of serum sodium, water retention.
3 Indication of any immediate medical attention and special treatment needed
Seek medical attention.
Fire-fighting measures
Extinguishing media : Water fog, dry chemical.
