Chronic:
Chronic ingestion may cause hypercalcemia, alkalosis, and kidney damage. May also produce
“milk-alkali syndrome” characterized by neurological symptoms such as irritability, lethargy,
stupor, and coma.
Section 4 - First Aid Measures
Eyes:
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids
until no evidence of chemical remains. Get medical aid at once.
Skin:
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated
clothing and shoes. Get medical aid if irritation develops.
Ingestion:
Do not induce vomiting. If victim is conscious, give 2-4 glasses of water or milk. Get medical aid
at once.
Inhalation:
Give artificial respiration if necessary. Move victim to fresh air. Keep victim warm and at rest. Get
medical aid at once.
Notes to Physician:
Treat symptomatically and supportively.
