4 FIRST AID MEASURES

General Measures: Under normal handling and use, exposure to solid forms of this material present few health hazards. Subsequent operations such as grinding, melting or welding may produce potentially hazardous dust or fumes which can be inhaled or come in contact with the skin or eyes. INHALATION: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult. Seek medical attention. INGESTION: Quickly wipe material from mouth and rinse with water. Do not induce vomiting. Seek medical attention. 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 Class D dry powder extinguishing agent. Unsuitable Extinguishing Media: Do not use water. Specific Hazards Arising from the Material: Lanthanum will burn under fire conditions. May react with water under fire conditions liberating flammable hydrogen gas. May emit fumes of lanthanum oxide 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. Avoid contact with skin and eyes. Avoid breathing dust or fume. Eliminate all sources of ignition. Isolate spill area. Methods and Materials for Containment and Cleaning Up: Sweep or scoop spilled product and place in a closed container for further handling and disposal. Do not use water for spill clean-up. Use only non-sparking tools and natural bristle brushes. 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 under dry protective gas such as argon. Handle in an enclosed, controlled process. Use non-sparking tools. Protect from sources of ignition. Protect from water/moisture. 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: Lanthanum metal should be stored in tightly-closed containers under argon or mineral oil. Keep away from sparks, heat and flame. Storage area should be free of combustibles and ignition sources. Protect from water/moisture. Do not store together with acids or oxidizers. See section 10 for more information on incompatible materials.

8 EXPOSURE CONTROLS AND PERSONAL PROTECTION

Exposure Limits: Lanthanum OSHA/PEL: No exposure limit established ACGIH/TLV: No exposure limit established Appropriate Engineering Controls: Handle in a humidity controlled atmosphere. Handle in an enclosed, controlled process under dry argon. Use local exhaust to maintain exposure at low levels. 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. 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. Prepare for the possibility of a fire. Keep extinguishing agents, tools for handling and protective clothing readily available. Individual Protection Measures, Such as Personal Protective Equipment: Respiratory Protection: Wear a NIOSH/MSHA approved respirator when high concentrations are present. Eye Protection: Always wear approved chemical splash proof goggles. Skin Protection: Rubber gloves, flame retardant protective work clothing.
