NO open flames.
Powder, alcohol-resistant foam, carbon dioxide.
EXPLOSION


EXPOSURE


•INHALATION
Ventilation.
Fresh air, rest.
•SKIN Redness.
Protective gloves.
Rinse skin with plenty of water or shower.
•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.
