======================= First Aid Measures =======================
Eyes:IMMED FLUSH IN DIRECTED STREAM OF H2O FOR @ LST 15 MIN
WHILE FORCIBLY HOLD LIDS APART TO ENSURE COMPLETE IRRIGATION OF ALL
EYE/LID TISSUE. GET MED ATTN. SKIN:IMMED FLUH W/PLENTY OF H2O FOR @
LST 15 MIN WHILE REMOVING CONTAMD CLTHG. SOAK AFFECTED AREA FOR 1
