4   FIRST AID MEASURES

General Measures: Remove patient from area of exposure.

INHALATION: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult. Seek medical attention.

INGESTION: Rinse mouth with water. Do not induce vomiting. Seek medical attention. Never induce vomiting or give anything by mouth to an unconscious person.

SKIN: Remove contaminated clothing, brush material off skin, wash affected area with soap and water. Seek medical attention if symptoms persist.

EYES: Flush eyes with lukewarm water, including under upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms persist.

Most Important Symptoms/Effects, Acute and Delayed: May cause irritation. See section 11 for more information.

Indication of Immediate Medical Attention and Special Treatment: No other relevant information available.

 

 

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 dust formation. Cleanup spills with a vacuum system utilizing a high efficiency particulate air (HEPA) filtration system and place in a closed container for further handling and disposal.

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 area. Store material tightly sealed in properly labeled containers. See section 10 for more information on incompatible materials.

 

 

8   EXPOSURE CONTROLS AND PERSONAL PROTECTION

Exposure Limits:     OSHA/PEL:                                                  ACGIH/TLV:

Cesium Molybdate      No exposure limit established                          No exposure limit established

Molybdenum              15 mg/m3 (insoluble compounds, total dust)     10 mg/m3 (insoluble compounds, inhalable)

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.

Acute and Chronic Effects:

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.

Molybdenum Compounds: There is considerable variability in the toxicity of molybdenum, depending on the chemical form and the animal species. Generally, soluble compounds are more toxic than insoluble compounds. When inhaled, both metallic molybdenum and sparingly soluble molybdenum trioxide have been reported to damage the lungs. A few cases of pneumoconiosis have been reported.

Acute Toxicity: No data

Carcinogenicity: NTP: Not identified as carcinogenic   IARC: Not identified as carcinogenic
