Health Hazards Information - Recommended Personal Protective Equipment: Use respirators for
spray, fogs, mists or dust; goggles; rubber gloves; Symptoms Following Exposure: Moderately irritating
to eyes and skin. Ingestion, absorption through skin, or inhalation of mist or dust may cause
excitability, convulsions, nausea, vomiting, diarrhea, and local irritation of the gastrointestinal tract;
General Treatment for Exposure: INHALATION: Administer victim oxygen and give fluid therapy;
do not give epinephrine, since it may induce ventricular fibrillation; enforce complete rest. EYES: flush
with water for at least 15 minutes. SKIN: wash off skin with large amounts of fresh running water and
wash thoroughly with soap and water. Do not scrub infected area of skin. INGESTION: induce
vomiting and follow with gastric lavage and administration of saline cathartics; ether and barbiturates
may control convulsions; oxygen and fluid therapy are also recommended. Do not give epinephrine.
