--------------------------FIRST AID MEASURES----------------------------
IF INHALED: REMOVE TO FRESH AIR. GIVE ARTIFICIAL RESPIRATION IF NOT
BREATHING. GET IMMEDIATE MEDICAL ATTENTION.

-----------------------HEALTH HAZARD INFORMATION------------------------
PRIMARY ROUTES OF EXPOSURE: SKIN OR EYE CONTACT
SIGNS AND SYMPTOMS OF EXPOSURE
INHALATION: DUSTS ARE EXTREMELY CORROSIVE TO THE ENTIRE RESPIRATORY
TRACT. BREATHING DUST CAN DESTROY THE MUCOUS MEMBRANES AND CAN CAUSE
SEVERE PNEUMONITIS.
EYE CONTACT: DUSTS ARE EXTREMELY CORROSIVE TO THE EYES. BRIEF CON-
TACT CAUSES SEVERE EYE DAMAGE AND PROLONGED CONTACT CAUSES PERMANENT
EYE INJURY WHICH MAY BE FOLLOWED BY BLINDNESS.
SKIN CONTACT: DUSTS ARE EXTREMELY CORROSIVE TO THE SKIN AND RAPIDLY
CAUSE SEVERE CHEMICAL BURNS. MOISTURE ON THE SKIN, SUCH AS FROM PER-
SPIRATION, WILL ACCELERATE TISSUE DESTRUCTION.
SWALLOWED: DUSTS OR SOLIDS ARE EXTREMELY CORROSIVE TO THE MOUTH
AND THROAT. SWALLOWING DUSTS OR SOLIDS CAUSES SEVERE AND RAPID BURNING
OF THE MOUTH, THROAT, AND DIGESTIVE TRACT ACCOMPANIED BY SEVERE PAIN,
VOMITING AND COLLAPSE. SOME EFFECTS MAY BE DELAYED.
CHRONIC EFFECTS OF EXPOSURE: MAY RESULT IN AREAS OF DESTRUCTION OF
SKIN TISSUE OR PRIMARY IRRITANT DERMATITIS. SIMILARLY, INHALATION OF
DUSTS, VAPORS, OR MISTS MAY CAUSE VARYING DEGREES OF DAMAGE TO THE
AFFECTED TISSUES AND ALSO INCREASING SUSCEPTIBILITY TO RESPIRATORY
ILLNESS.
MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: NONE KNOWN.
