Health Hazards Acute and Chronic:INHALED: DUST IS IRRITATING TO THE
NOSE, THROAT AND RESPIRATORY TRACT, AND MAY CAUSE COUGHING AND
SNEEZING. SKIN: PROLONGED AND REPEATED CONTACT MAY CAUSE MILD
IRRITATION. EYES: MAY CAUSE IRRITATION, REDNESS AND PAIN.
INGESTED: INGESTION OF LARGE AMOUNTS OF DUST MAY CAUSE
GASTROINTESTINAL UPSET AND ABDOMINAL PAIN.. OTHER HEALTH EFFECTS:
FORMS CORROSIVE SOLUTIONS WHEN DISSOLVED IN WATER (OR TEARS). HIGH
BLOOD CONCENTRATIONS OF UREA INCREASE THE RISK OF GLAUCOMA.
Effects of Overexposure:INHALED: DUST IS IRRITATING TO THE NOSE, THROAT
AND RESPIRATORY TRACT, AND MAY CAUSE COUGHING AND SNEEZING. SKIN:
PROLONGED AND REPEATED CONTACT MAY CAUSE MILD IRRITATION. EYES: MAY
CAUSE IRRITATION, REDNESS AND PAIN. INGESTED: INGESTION OF LARGE
AMOUNTS OF DUST MAY CAUSE GASTROINTESTINAL UPSET AND ABDOMINAL
PAIN.. OTHER HEALTH EFFECTS: FORMS CORROSIVE SOLUTIONS WHEN
DISSOLVED IN WATER (OR TEARS). HIGH BLOOD CONCENTRATIONS OF UREA
INCREASE THE RISK OF GLAUCOMA.

First Aid:INHALED: MOVE VICTIM TO FRESH AIR. GIVE ARTIFICIAL REPIRATION
ONLY IF BREATHING HAS STOPPED. GIVE CARDIOPULMONARY RESUSCITATION
(CPR) IF THERE IS NO BREATHING AND NO PULSE. OBTAIN MEDICAL ADVICE
IMMED IATELY. SKIN: REMOVE CONTAIMINATED CLOTHING. WASH AFFECTED
AREA THOROUGHLY QITH SOAP AND WATER. IF IRRITATION PERSISTS. OBTAIN
MEDICAL ADVICE. EYES: IMMEDIATELY FLUSH EYES THOROUGHLY FOR 15
MINUTES W ITH RUNNING WATER. HOLD EYELIDS OPEN DURING FLUSHING. IF
