empty. Protect from damage. Store away from incompatible
materials.
FIRST AID MEASURES
Specific Measures:
Eyes: Immediately flush eyes with gently running water,
holding eyelids open while flushing, for five to ten (5-10)
minutes, or until no trace of chemical remains. If irritation
persists, obtain medical attention.
Skin: Remove contaminated clothing. Brush or wipe off dry
material. Flush affected areas with soap and running water
for for five to ten (5-10) minutes, or until no trace of chemi-
cal remains. If irritation persists, or if exposure was
extensive, obtain medical attention.
