V HEALTH HAZARD INFORMATION

Health Hazards (Acute and Chronic):
To the best of our knowledge the chemical, physical and toxicological properties of iron boride have not been thoroughly
investigated and recorded.
Iron compounds have varying toxicity. Some iron compounds are suspected carcinogens. In general, ferrous compounds are
more toxic than ferric compounds. Acute exposure to excessive levels of ferrous compounds can cause liver and kidney damage,
altered respiratory rates and convulsions (Sax, dangerous Properties of Industrial Materials, eighth edition).
Boron compounds are very toxic and therefore considered and industrial poison. Boron is one of a group of elements, such
as Pb, Mn, As, which affects the central nervous system. Boron poisoning causes depression of the circulation, persistent vomiting
and diarrhea, followed by profound shock and coma. The temperature becomes subnormal and a scarlatina form rash may cover the
entire body (Sax, Dangerous Properties of Industrial Materials, eighth edition).
Inhalation: Acute: Inhalation of dust or powder may cause irritation to the respiratory system, boron and possibly acute iron
poisoning. Large amounts or iron may cause iron pneumoconiosis.
Chronic: Inhalation of finely divided powder may cause pulmonary fibrosis. May cause chronic iron poisoning and pathological
deposition of iron in the body tissue.
Ingestion: Acute: May cause gastrointestinal irritation and boron poisoning.
Chronic: May affect the central nervous system and cause damage to the liver.
Skin: Acute: May cause irritation.
Chronic: May cause dermatitis.
Eye: Acute: May cause irritation.
Chronic: No chronic health effects recorded.
Recommended Exposure Limits: See 鈥淪ection II鈥?
LD50/LC50: No toxicity data recorded
Signs and Symptoms of Exposure:
Inhalation: May cause a red, dry, throat and coughing. Acute iron poisoning may cause: biphasic shock, rapid increase in respiration
and pulse rate, congestion of blood vessels which may lead to hypotension, pallor and drowsiness. Chronic iron poisoning may
cause: hemorrhagic necrosis of the gastrointestinal tract, hepatotoxicity, metabolic acidosis, prolonged blood clotting time, elevation
of plasm levels of serotonin and histamine. Symptoms of pathological deposition of fibrosis of the pancreas, diabetes, mellitus and
liver cirrhosis. Boron poisoning may cause: Depression of the circulation, persistent vomiting, diarrhea, shock and coma.
Ingestion: Boron poisoning may cause: depression of the circulation, persistent vomiting, diarrhea, shock and coma.
Skin: May cause redness, inflammation and itching.
Eye: May cause redness, itching and watering.
Medical Conditions Generally Aggravated by Exposure: Pre-existing respiratory disorders
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: Remove victim to fresh air; keep warm and quiet; give oxygen if breathing is difficult and seek medical attention.
INGESTION: Give 1-2 glasses of milk or water and 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 mild soap and water; seek medical attention
if symptoms persist.
EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms
persist.
VI REACTIVITY DATA
Stability: Stable
Conditions to Avoid-Instability: None
Incompatibility (Material to Avoid): Water, moisture, strong acids and bases.
Hazardous Decomposition or Byproducts: Hydrogen gas.
Hazardous Polymerization: Will not occur.
Conditions to Avoid Hazardous Polymerization: None
VII SPILL OR LEAK PROCEDURES
Steps to Be Taken in Case Material Is Released or Spilled: Wear appropriate respiratory and protective equipment specified in
Section VIII-Special Protection Information. Isolate spill area, provide ventilation and extinguish sources of ignition. Vacuum up
spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal. Take care not to
raise dust. Use non-sparking tools.
VII SPILL OR LEAK PROCEDURES
Waste Disposal Method: In accordance with Local, State and Federal Waste Disposal Regulations.
Hazard Label Information: Store in a cool, dry area in a tightly sealed container. Wash thoroughly after handling.
Precautions to Be Taken in Handling and Storing: Iron boride may react with water and moisture to for hydrogen gas. Handle and
store in a controlled environment and inert gas such as argon.
Other precautions: None
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection (Specify Type): NIOSH-approves dust-mist-vapor cartridge respirator.
Ventilation: Local Exhaust: To maintain concentration at or below the PEL, TLV.
Mechanical (General): Not recommended.
Special: Handle in a controlled, enclosed environment. Other: None
Protective Gloves: Rubber gloves Eye Protection: Safety glasses
Other Protective Clothing or Equipment: Protective gear suitable to prevent contamination.
Work/Hygienic/Maintenance Practices: Implement engineering and work practice controls to reduce and maintain concentration of
exposure at low levels. Use good housekeeping and sanitation practices. So not use tobacco or food in work area. Wash thoroughly
before eating and smoking. Do not blow dust off clothing or skin with compressed air.
