NO open flames.
Powder, water spray, foam, carbon dioxide.
EXPLOSION


EXPOSURE
PREVENT GENERATION OF MISTS!

 •INHALATION
Ventilation.
Fresh air, rest. Refer for medical attention.
 •SKIN Redness. Pain.
Protective gloves.
Rinse skin with plenty of water or shower. Refer for medical attention.
 •EYES Redness. Pain.
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION
Do not eat, drink, or smoke during work.
Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give plenty of water to drink. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place.
Separated from strong oxidants. Well closed. Keep in a well-ventilated room.
