V.   HEALTH HAZARD INFORMATION

Health Hazards:

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).

Acute Effects:

Inhalation:  May cause irritation to the upper respiratory system and mucous membranes.

Ingestion:  May cause gastrointestinal disturbances

Skin:  May cause irritation.

Eyes:  may cause moderate irritation.

Chronic Effects:

Inhalation:  May cause writhing, ataxia, labored respiration, walking on toes with arched back, sedation, pneumonoconiosis, hemoglobinemia and lung  granuloma.

Ingestion:  May act as a blood anticoagulant and cause boron poisoning.

Skin:  No chronic health effects recorded.

Eyes: No chronic health effects recorded.

Target Organs:  May affect the blood, lungs and central nervous system.

Medical Conditions Aggravated by Overexposure:  Pre-existing respiratory disorders.

CarcinogenicityNTP:  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.

 

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 attention.

EYES:  Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minuets.  Seek Medical Attention.

 

 

VI.   REACTIVITY DATA

Stability:  Stable

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:

‚             Store in tightly closed containers.

‚             Wash thoroughly after handling.

‚             Store in a cool, dry place.
