5   FIREFIGHTING MEASURES

Extinguishing Media: Use suitable extinguishing agent for surrounding materials and type of fire.

Unsuitable Extinguishing Media: No information available.

Specific Hazards Arising from the Material: May emit toxic fumes under fire conditions.

Special Protective Equipment and Precautions for Firefighters: Full face, self-contained breathing apparatus and full protective clothing to prevent contact with skin and eyes.

 

 

6   ACCIDENTAL RELEASE MEASURES

Personal Precautions, Protective Equipment, and Emergency Procedures: Wear appropriate respiratory and protective equipment specified in section 8. Isolate spill area and provide ventilation. Avoid breathing dust or fume. Avoid contact with skin and eyes. Eliminate all sources of ignition.

Methods and Materials for Containment and Cleaning Up: Avoid raising dust. Scoop or vacuum up using a vacuum system equipped with a HEPA filter. Place in properly labeled closed containers.

Environmental Precautions: Do not flush to sewer, stream, or other bodies of water. Do not allow to enter drains or to be released to the environment.

 

 

7   HANDLING AND STORAGE

Precautions for Safe Handling: Handle in an enclosed, controlled process. Avoid creating dust. Provide adequate ventilation if dusts are created. Avoid breathing dust or fumes. Avoid contact with skin and eyes. Wash thoroughly before eating or smoking. See section 8 for information on personal protection equipment.

Conditions for Safe Storage, Including Any Incompatibilities: Store in a cool, dry, well-ventilated area. Store material tightly sealed in properly labeled containers. Protect from moisture. See section 10 for more information on incompatible materials.

 

 

8   EXPOSURE CONTROLS AND PERSONAL PROTECTION

Exposure Limits:   OSHA/PEL:                               ACGIH/TLV:

Cesium Fluoride       No exposure limit established       No exposure limit established

Fluorides (as F)        2.5 mg/m3                                 2.5 mg/m3

Appropriate Engineering Controls: Whenever possible the use of local exhaust ventilation or other engineering controls is the preferred method of controlling exposure to airborne dust and fume to meet established occupational exposure limits. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating or smoking. Do not blow dust off clothing or skin with compressed air.

Individual Protection Measures, Such as Personal Protective Equipment:

   Respiratory Protection: Wear a NIOSH/MSHA approved respirator when high concentrations are present.

   Eye Protection: Safety glasses

   Skin Protection: Wear impermeable gloves, protective work clothing as necessary.

11   TOXICOLOGICAL INFORMATION

Likely Routes of Exposure: Inhalation, skin and eyes.

Symptoms of Exposure: May cause irritation to eyes and abraded skin. May cause irritation to lungs.

Acute and Chronic Effects: To the best of our knowledge the chemical, physical and toxicological characteristics of the substance are not fully known.

Cesium Compounds: Cesium hydroxide is extremely irritating to eyes and skin. It is likely that this effect is the result of the caustic nature of the hydroxide rather than an effect due to cesium per se. Cesium ions block potassium channels in biological membranes in a voltage dependent manner. It has been found that replacing the potassium in the diet of rats with cesium caused death after 10-17 days.

Fluorides: Acute effects resulting from exposure to inorganic fluorides are mainly due to the effects of hydrogen fluoride, a colorless gas or liquid. The major health effect of chronic inhalation exposure to fluoride compounds is skeletal fluorosis, which has been reported in cases of exposure to fluoride dusts and hydrogen fluoride, either individually or in combination. Excluding sodium fluoride, effects of exposure to inorganic fluoride compounds has not been well studied. Based on single exposure animal tests, sodium fluoride is considered to be moderately toxic if swallowed, no more than slightly toxic if absorbed through the skin, slightly irritating to skin and corrosive to eyes.

Acute Toxicity: No data
