Primary skin and eye irritation, cutaneous sensitization, and oral acute toxicity studies were conducted on the hydroxides of cesium (7440462), rubidium, and potassium (7440097) and the iodides of cesium and rubidium. The hydroxides of cesium and rubidium were markedly more toxic than the iodides. Potassium-hydroxide (1310583) was irritating to both intact and abraded skin, whereas cesium- hydroxide and rubidium-hydroxide were irritating only to abraded skin. Cesium-iodide and rubidium-iodide did not affect the eye or skin. It was concluded that personal protective equipment and clothing should be worn when working with cesium, rubidium, or potassium hydroxides. These studies indicate that cesium and rubidium are only slightly toxic on an acute toxicologic basis and would pose an acute health hazard only when ingested in large quantities.
