SECTION 2: Hazards identification
Emergency Overview ***** Cesium hydroxide exists as colorless, white, or yellowish crystals. It readily absorbs moisture from air and surfaces. It is the strongest known base and is highly corrosive to all body surfaces.
Principle Routes of Exposure
Inhalation, skin and eye contact Target Organs: Eyes, skin, respiratory tract. Acute Effects: Because cesium hydroxide is used in such small quantities, toxicity data for industrial exposures is Iittle or non-existent. However, it is becoming more widely used which may result in future toxic exposures. Because cesium is similar to lithium, it is expected that overexposure may result in central neryous system effects. Inhalation: Inhalation ofdusts can cause severe irritation and possible burns ofthe respiratory tract. The severity is due to cesium hydroxide's ability to extract moisture from the mucous membranes. Eye: Corrosive. May cause perrnanent damage. Skin: Highly irritating and can be corrosive, especially if skin is moist- Ingestion: Severe irritation and possible burns ofthe gastrointestinal tracl Carcinogenicity: ACGIH, IARC, NTP, and OSHA do not list cesium hydroxide'as a carcinogen.
Medical Conditions Generally Aggravated by Exposure
None reported
Potential chronic health
None reported Other: Cesium hydroxide has been shown not to be a sensitizer in animal studies.
