V HEALTH HAZARD INFORMATION
Routes of Entry: Inhalation, skin, eyes, ingestion.
Health Hazards (Acute and Chronic):
To the best of our knowledge the chemical, physical and toxicological properties of nickel boride have not been thoroughly
investigated and recorded.
Nickel is a confirmed carcinogen with experimental carcinogenic, neoplastigenic, tumorigenic and teratogenic data. Poison
by ingestion, intratracheal, intraperitoneal, subcutaneous and intravenous routes. An experimental teratogen. Ingestion of soluble
salts causes nausea, vomiting and diarrhea. Hypersensitivity to nickel is common and can cause allergic contact dermatitis, pulmo-
nary asthma, conjunctivitis and inflammatory reactions around nickel containing medical implants and prosthesis (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 because subnormal and scarlentina form rash may cover the
entire body (Sax, Dangerous Properties of Industrial Materials, eighth edition).
Inhalation: Acute: May cause irritation to the upper respiratory tract, mucous membranes, nasal cavities and boron poisoning. May
cause pulmonary asthma attacks.
Chronic: Prolonged or repeated inhalation may cause pneomitis.
Ingestion: Acute: Large doses may cause boron poisoning, intestinal disorders, convulsions and asphyxia.
Chronic: May cause nickel toxicity affect the central nervous system.
Skin: Acute: May cause irritation.
Chronic: May sensitize the skin (nickel itch). May cause allergic dermatitis, eczematous dermatitis and may be accompanied a week
later with superficial skin ulcers, which may discharge and become crusted.
Eye: Acute: May cause irritation.
Chronic: May cause conjunctivitis.
Medical Conditions Generally Aggravated by Exposure: Pre-existing respiratory disorders, pulmonary functions, asthma and skin
Target Organs: May affect the nasal cavities, respiratory system, lungs, central nervous system, blood and skin.
Carcinogenicity: NTP? Yes IARC Monographs? Yes OSHA Regulated? Yes
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, sore nose and throat, coughing and shortness of breath. Boron poisoning may cause: depression of
circulation, persistent vomiting, diarrhea, shock and coma.
Ingestion: May cause gastritis, convulsions, asphyxia, giddiness, nausea, diarrhea and vomiting. Nickel toxicity may cause: gastro-
enteritis; Nervous symptoms such as tremor, chorea-like movements and paralysis occur prior to death, which occurs mostly from
heart failure. Boron poisoning may cause depression of the circulation, persistent vomiting, diarrhea, shock and coma.
Skin: May cause res, itching, swelling, burning and ulcers.
Eye: May cause red, 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 immediately. 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 with lukewarm water, lifting upper and lower lids for at least 15 minutes. Seek medical attention if symptoms persist.
VI REACTIVITY DATA

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 and provide ventilation. 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.
Waste Disposal Method: In accordance with all applicable Federal, State, and local regulations.
Hazard Label Information: Store in a cool dry place in a tightly sealed container. Wash thoroughly after handling.
Precautions to Be Taken in Handling and Storing: None
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. Other: None
Special: Handle in a controlled environment when in dust or powder form. Mechanical (General): Recommended
Protective Gloves: Rubber
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. 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.
