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.

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

Special Protective Equipment and Precautions for Firefighters: Wear full face, self-contained breathing apparatus and full protective clothing.




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 allow to enter drains or to be released to the environment.




Precautions for Safe Handling: Handle in an enclosed, controlled process. Avoid creating dust. Avoid breathing dust or fumes. Provide adequate ventilation if dusts are created. 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: Store in a cool, dry area. Store material tightly sealed in properly labeled containers. Protect from moisture. See section 10 for more information on incompatible materials.




Exposure Limits:    OSHA/PEL:                               ACGIH/TLV:

Iron Boride               No exposure limit established      No exposure limit established

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: Use suitable respirator when dust or fumes are present.

   Eye Protection: Safety glasses

   Skin Protection: Impermeable gloves, protective work clothing as necessary.

Likely Routes of Exposure: Inhalation, skin and eyes.

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

Acute and Chronic Effects:

Iron Oxide:  Inhalation of nanoparticles:  No adverse effects were reported in all of the reviewed clinical studies using iron oxide tracer aerosols. Although most were designed to determine deposition and clearance of particles in the lungs versus toxicological endpoints, the few that did assess biomarkers of exposure did not report acute effects from inhalation. Acute effects are also not associated with workplace exposure to dusts and fumes primarily composed of iron oxide. While increased risk of developing lung disease has been correlated with iron oxide exposure, co-exposure to other known carcinogens present in the dusts and fumes as well as smoking confound the relationship.1

Iron Compounds/Iron Salts:  Irritating to the respiratory tract, iron compounds may cause pulmonary fibrosis if dusts are inhaled. Inhalation of large amounts may cause iron pneumoconiosis. Inhalation of ferric salts as dusts & mists is irritating to the respiratory tract. Ferric salts are regarded as skin irritants.

Boron Compounds:  Only a few human studies have been conducted to assess health effects associated with exposure to boron compounds. The available data show that exposure is associated with short-term irritant effects on the upper respiratory tract, nasopharynx, and eye. These effects, however, appear to be short-term and reversible. The sole long-term (7-year) follow-up study failed to identify any long-term health effects. No studies have been identified that assess reproductive outcomes. From 782 cases of boric acid ingestion … all except two cases were acute ingestions; 88.3% were asymptomatic. Among the remaining 11.7%, frequent symptoms included vomiting, abdominal pain, and diarrhea; less frequent findings included lethargy, headache, lightheadedness, and rash. Among the children less than 6 years of age, 21 ingested more than the estimated lethal dose of 15 g, all without severe manifestations of toxicity or life-threatening symptoms. In this series only minimal toxicity was seen at serum levels of less than or equal to 640 mg/mL.
