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

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID ALL CONTACT!

•INHALATION Cough. Laboured breathing. Sore throat.
Ventilation.
Fresh air, rest. Half-upright position. Refer for medical attention.
•SKIN Redness. Pain.
