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
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:

鈥tore in tightly closed containers.
鈥ash thoroughly after handling.
鈥tore in a cool, dry place.

Some of the chemicals listed herein are research or experimental substances which may be toxic, as defined by various
governmental regulations. In accordance with EPA regulations and the Toxic Substance Control Act (TSCA), these materials should
only be handled by, or under the direct supervision of, a 鈥渢echnically qualified individual鈥?, as defined in 40 CFR 710.2(aa).
The above information is accurate to the best of our knowledge. However, since data, safety standards, and government
regulations are subject to change, and the conditions of handling and use or misuse are beyond our control, ESPI makes no warranty,
either expressed or implied, with respect to the completeness or continuing accuracy of the information contained herein, and
disclaims all liability for reliance thereon. Users should satisfy themselves that they have all current data relevant to their particular
use.
