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 evolve 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.
Methods and Materials for Containment and Cleaning Up: Avoid dust formation. Scoop up or vacuum using a vacuum equipped with a HEPA filter and place in a properly labeled 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:
Magnesium Tungstate No exposure limit established No exposure limit established
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 dusts or fumes 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:
Magnesium Compounds: Inhalation of excessive concentrations of magnesium oxide fume may cause metal fume fever. Oral administration of magnesium salts may cause vomiting with few other effects unless, however evacuation fails, then mucosal irritation and absorption occur. Overexposure via oral, intravenous and intraperitoneal routes to magnesium (+2) salts may affect the central nervous, heart and respiratory systems.
Tungsten Compounds: Respiratory effects were reported in workers who were occupationally exposed to airborne dusts containing tungsten trioxide, tungsten dioxide, metallic tungsten, and tungsten carbide in areas where high tensile strength tungsten (hard metal) was prepared. It is generally believed that the health effects observed in hard metal workers are the result of exposure to cobalt or other metals, not tungsten. In a study with rats, it was demonstrated that intratracheally-instilled tungsten carbide and cobalt in combination, but not alone, induced interstitial pulmonary fibrosis. Acute oral exposure to tungsten does not appear to be a particular toxicity concern, based on acute oral LD50 values ranging from 240 to 11,300 mg/kg/day for several soluble tungsten compounds. No human data were located in which systemic toxicity could be associated with oral exposure to tungsten or tungsten compounds. Signs of slight conjunctival irritation were noted in rabbits following single ocular instillation of 100 mg of sodium tungstate dihydrate powder or tungsten metal powder.
Acute Toxicity: No data
