Health Hazards Information - Recommended Personal Protective Equipment: Dust mask; goggles or
face shield; protective gloves; Symptoms Following Exposure: Ingestion (or inhalation of excessive
amounts of dust) causes rapid drop in blood pressure, persistent and throbbing headache, vertigo,
palpitations, and visual disturbances; skin becomes flushed and sweaty, later cold and cyanotic; other
symptoms include MUS=, vomiting, diarrhea (sometimes), fainting, methemoglobinemia. Contact with
eyes causes irritation; General Treament for Exposure: INHALATION: move to fresh air; if exposure
is severe, get medical attention. INGESTION: keep patient recumbent in a shock position and
comfortably warm; administer gastric lavage; consult a physician. EYES or SKIN: flush with water;
