Oxidizing Agents, Strong

Explosive

BARIUM CHLORATE is an oxidizing agent. Liberates explosive chlorine dioxide gas in the presence of a strong acid. Heating a moist metal chlorate and a dibasic organic acid liberates chlorine dioxide and carbon dioxide [Bretherick 1979 p. 100]. Mixtures with ammonium salts, powdered metals, silicon, sulfur, or sulfides are readily ignited and potentially explosive [Bretherick 1979 p. 806]. A combination, in finely divided form with finely divided aluminum can explode by heat, percussion, or friction [Mellor 2:310 1946-4].

A solution of barium chloride was injected intramuscularly into five children and intravenously into two adults, all with normal skeletal metabolism. Three of the children and one adult also received calcium chloride in the same injection. Following injection, the concentration of barium in the serum fell rapidly for about 0.6 day and then more slowly; even so, the amount detected on day 6 was less than 0.0002% of the dose. The pattern of excretion of calcium was similar, but both the initial and final rates were slower. Bone took up barium more rapidly than calcium under the same conditions, but, because of the more rapid excretion of barium, less of it was available to the bone.

Inhalation causes irritation of upper respiratory system. Contact with eyes or skin causes irritation. Ingestion causes abdominal pain, nausea and vomiting, diarrhea, pallor, blueness shortness of breath, excessive salivation, convulsive tremors, slow, hard pulse, elevated blood pressure, unconsciousness. Hemorrhages may occur in the stomach, intestines, and kidneys. Muscular paralysis may follow. (USCG, 1999)
