Exposure effects
   Ingestion
May cause irritation of the digestive tract. The toxicological properties of this substance have not been fully investigated. Cesium is similar to potassium in its elemental state. It has been shown to have physiological action in experimentation with animals. Hyper-irritability, includingmarked spasms, has been shown to follow the administration of cesium in the diet of rats.
   Inhalation
May cause respiratory tract irritation. The toxicological properties of this substance have not been fully investigated.
   Skin
May cause skin irritation.
   Eyes
May cause eye irritation.
