Health IIazards Information - Recommended Personal Protective Equipment: Approved dust
respirator, chemical goggles: rubber or plasticcoated gloves; Symptoms Following Exposure: Inhalation
of dust can cause systemic poisoning. Ingest ion causes burning pain in throat, esophagus, and stomach;
exposed areas of mucous membrane turn white; vomiting, severe purging, weak pulse, and
cardiovascular collapse may result; if death is delayed, neuromuscular symptoms develop. Contact with
eyes or skin causes irritation; General Treatment for Exposure: Actpromptly! INJ3ALATION: remove
victim to fresh air; if exposure to dust is severe, get medical attention. INGESTION: call physician
immediately: have victim drink dilute calcium lactate, lime water, chalk soh, or even milk; large
amounts of calcium arc required; administer gastric lavage with dilute lime water; watch for edema of
the glottis and delayed constriction of esophagus. EYES: flush with water and seek medical attention.
