CAS: 7778-77-0

OSHA PEL N/K

ACGIH TLV: N/K

Routes of Entry: Inhalation:YES Skin:YES Ingestion:YES
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:ACUTE: INHALATION: MAY CAUSE MILD
IRRITATION TO THE RESPIRATORY TRACT. INGESTION: PHOSPHATES ARE
SLOWLY AND INCOMPLETELY ABSORBED WHEN INGESTED, AND SELDOM RESULT
IN SYSTEMIC EFFECTS. SUCH EFFECTS, HO WEVER, HAVE OCCURRED.
SYMPTOMS MAY INCLUDE VOMITING, LETHARGY, DIARRHEA, BLOOD CHEMISTRY
EFFECTS, CARDIAC EFFECT AND CENTRAL NERVOUS SYSTEM EFFECTS. THE
TOXICITY OF PHOSPHATES IS BECAUSE OF THEIR ABIL ITY TO SEQUESTER
CALCIUM. ACUTE POTASSIUM INTOXICATION BY MOUTH IS RARE BECAUSE
LARGE SINGLE DOSES USUALLY INDUCE VOMITING AND BECAUSE IN THE
ABSENCE OF PRE-EXISTING KIDNEY DAMAGE, POTASSIUM IS RAPIDL Y
EXCRETED. (EFTS OF OVEREXP)
Effects of Overexposure:HLTH HAZ: POTASSIUM POISONING CAN RESULT IN
HEART EFFECTS, CHANGES IN RESPIRATION RATE, TINGLING IN THE
EXTREMITIES, HEAVINESS IN THE LIMBS, NAUSEA AND DIARRHEA. SKIN:
IRRITANT DUE TO ITS ACIDIC NATUR E. MAY CAUSE INFLAMMATION AND PAIN
ON PROLONGED CONTACT, ESPECIALLY WITH MOIST SKIN. EYE: MAY CAUSE
IRRITATION, REDNESS AND PAIN. CHRONIC: MAY SEQUESTER CALCIUM AND
CAUSE CALCIUM PHOSPHATE DEPOSITS IN THE KIDNEYS.
Medical Cond Aggravated by Exposure:PERSONS WITH IMPAIRED KIDNEY
FUNCTIONS MAY BE MORE SUSCEPTIBLE TO THE EFFECTS OF THE SUBSTANCE.

First Aid:INHALATION: REMOVE TO FRESH AIR. GET MEDICAL ATTENTION FOR
ANY BREATHING DIFFICULTY. INGEST: IF SWALLOWED, GIVE SEVERAL
GLASSES OF WATER TO DRINK TO DILUTE. IF LARGE AMTS WERE

DRINK TO DILUT E. IF LRG AMTS WERE SWALLOWED/SYMP OCCUR, GET MED
ADVICE. NEVER GIVE ANYTHING BY MOUTH TO AN UNCON P ERS.
