Effects of Exposure: ACUTE: DIRECT EYE CNTCT MAY CAUSE TEMPORARY DISCOMFORT
W/MILD REDNESS & DRYNESS SIMILAR TO WINDBURN. SKIN: SINGLE PRLNGD EXPOS
(24 TO 48 HRS) CAUSES NO KNOWN ADVERSE EFT. INHAL: NO IRRIT TO EYES & RES
P PASSAGES. NO INJURY IS LIKELY FROM RELATIVELY SHORT EXPOS OF LESS THAN 8
HRS. INGEST: SM AMTS TRANSFERRED TO MOUTH BY FINGERS DURING USE, ETC, SHOULD
NOT INJURE. SWALLOWING LARGE AMTS MAY CAUSE DIGE STIVE DISCOMFORT. REPEATED
