V HEALTH HAZARD INFORMATION
Routes of Entry: Inhalation
Health Hazards (Acute and Chronic):
To the best of our knowledge the chemical, physical and toxicological properties of neodymium boride have not been
thoroughly investigated and recorded.
Neodymium is considered a rare earth metal. These metals are moderately to highly toxic. The symptoms of toxicity of the
rare earth elements include writhing, ataxia, labored respiration, walking on the toes with arched back and sedation. The rare earth
elements exhibit low toxicity by ingestion exposure. However, the intraperitoneal route is highly toxic while the subcutaneous route
is poison to moderately toxic. The production of skin and lung granulomas after exposure to them requires extensive protection to
prevent such exposure (Sax, Dangerous Properties of Industrial Materials, 8th 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, 8th edition).
Inhalation: Acute: May cause irritation to the upper respiratory system and mucous membranes.
Chronic: May cause writhing, ataxia, labored respiration, walking on toes with arched back, sedation, pneumonoconiosis, hemoglo-
binemia and lung granuloma.
Ingestion: Acute: May cause gastrointestinal disturbances
Chronic: May act as a blood anticoagulant and cause boron poisoning.
Skin: Acute: May cause irritation.
Chronic: No chronic health effects recorded.
Eyes: Acute: may cause moderate irritation.
Chronic: No chronic health effects recorded.
Target Organs: May affect the blood, lungs and central nervous system.
Carcinogenicity: NTP: No IARC Monographs: No OSHA Regulated: No
Signs and Symptoms of Exposure:
Inhalation: May cause a red, dry throat, congestion, sneezing, and coughing.
Ingestion: May affect the coagulation time of blood. Boron poisoning may cause: a below normal temperature, poor circulation,
vomiting and diarrhea.
Skin: May cause redness, burning, and itching.
Eyes: May cause redness, burning, itching, and watering.
Medical Conditions Aggravated by Overexposure: 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 and wash affected area with mild soap and water. Seek medical
EYES: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minuets. Seek Medical Attention.
VI REACTIVITY DATA
Incompatibility (Material to Avoid): None recorded.
Hazardous Decomposition Products: None recorded
Hazardous Polymerization: Will not occur
VII SPILL OR LEAK PROCEDURES
Steps to Be Taken in Case Material Is Released or Spilled: Wear appropriate protective gear. Isolate spill area and provide
ventilation. Vacuum up spill area using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for
proper disposal. Avoid creating dusting conditions.
Waste Disposal Method: In accordance with Local, State and Federal Waste Disposal Regulations.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection (Specify Type): NIOSH approved dust respirator
Ventilation: Local: To maintain concentration at low exposure levels. Other: None
Mechanical: Recommended Special: None
Protective Gloves: Rubber Eye Protection: Safety Goggles
Other Protective Clothing: 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. Do 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.
IX SPECIAL PRECAUTIONS
Other Handling and Storage Conditions:
鈥tore in tightly closed containers.
鈥ash thoroughly after handling.
鈥tore in a cool, dry place.
