SECTION 4. FIRST AID MEASURES

INHALATION: Remove from exposure, keep warm and quiet, give oxygen if breathing is difficult, seek immediate medical attention.
INGESTION: If conscious, give 1-2 glasses of milk or water and induce
vomiting, call a physician immediately. Never give anything by mouth to an unconscious person.
SKIN: Remove contaminated clothing from affected area, brush material off skin, wash affected area with mild soap and water, seek medical attention immediately.

Extinguishing Media: N/A, Use fire extinguishing agent for surrounding material and type of fire.
Special Fire Fighting Procedures: Firefighters must wearfull face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes. Fumes form fire are hazardous. Isolate run off to prevent environmental pollution.

SECTION 6. ACCIDENTAL RELEASE MEASURES

Steps to be taken in case material is released or spilled: Wear appropriate respiratory and protective equipment specified in section 8 Special Protection Information. Isolate spill area and provide proper 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.

SECTION 7. HANDLING AND STORAGE

Precautions to Be Taken in Handling and Storage: Store in cool, dry place in tightly closed containers. Wash thoroughlyafter handling. Store in a tightly sealed container. Open and handle container with care. Ensure good ventilation at the workplace.

SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION

Respiratory Protection: Use suitable respirator when high concentrations are present. Select according to OSHA 29 CFR 1910.1018(h)(2)(i) Table 1 and 2.
Ventilation: Use local exhaust to maintain concentrations at or below PEL, TLV. Handle in a controlled atmosphere. Mechanical exhaust is not recommended.
Eye Protection: Safety goggles or face shield.
Protective Gloves: Impervious gloves
Other Protective Equipment: Protective gear suitable to prevent contamination.

Work 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 with compressed air.

SECTION 11. TOXICOLOGICAL INFORMATION

Routes of Entry: Inhalation, Ingestion, Skin, and Eyes.
Health Hazards(Acute and Chronic):
To the best of our knowledge the chemical, physical and toxicological properties of niobium arsenide have not been thoroughly investigated and recorded. Niobium is considered a rare earth metal. These metals are moderately to highly toxic. The symptoms of toxicity of rare earth elements include writhing, ataxia, labored respiration, walking on toes with arched back and sedation. The rare earth elemtns 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, eighth edition).
Inorganic arsenic compounds are confirmed human carcinogens producing tumors of the mouth, esophagus, larynx, bladder, and para nasal sinus. A recognized carcinogen of the skin, lungs, and liver. Poisoning from arsenic compounds may be acute or chronic. Acute poisoning usually results from swallowing arsenic compounds, chronic from either swallowing or inhaling(Sax, Dangerous Properties of Industrial Materials, eighth edition).
Acute Effects:
Inhalation: DANGER-POISON. May cause irritation to the respiratorysystem, garlic odor of the breath, pallor, nervousness and depression.
Ingestion: DANGER-POISON. May cause systemic gastrointestinal and skin effects and acute arsenic poisoning.
Skin: May cause irritation and skin abnormalities.
Eye: May cause irritation.
Chronic Effects:
Inhalation: DANGER-POISON. May cause bronchitis, chronic arsenic poisoning, ulceration of the nasal septum, liver damage and cancer/ disease of the blood, kidneys and nervous system.
Ingestion: DANGER-POISON. May cause chronic arsenic poisoning, gastrointestinal disturbances, liver damage and cancer/disease of the blood, kidneys and nervous system.
Skin:May cause irritation, occasional ulceration, spotty pigmentation, dermatitis, skin cancer and keratosis(especially on soles and palms).
Eye: May cause disturbances, such as blurred vision.
Target Organs: May effect the upper respiratory system, eyes, skin, blood, liver, kidneys, skin, lungs and lymphatic system.
Carcinogenicity: NTP: Yes
IARC Monographs: Yes
OSHA Regulated: Yes
Medical Conditions Possibly Aggravated: Pre-existing skin and respiratory disorders.
