V HEALTH HAZARD INFORMATION

Route(s) of Entry: Inhalation? Yes Skin? Yes Ingestion? Yes

Health Hazards (Acute and Chronic):

To the best of our knowledge the chemical, physical and toxicological properties of nickel antimonide 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).


Inhalation: Acute: DANGER-POISON. May cause irritation to the upper respiratory tract, mucous membranes, nasal cavities and
septal ulceration. May cause pulmonary asthma attacks.
Chronic: Prolonged or repeated inhalation may cause pneomitis, pneumonitis, liver and kidney abnormalities.

Ingestion: Acute: DANGER-POISON. May cause irritation to the lining of the stomach and intestines. Large doses may cause
intestinal disorders, convulsions and asphyxia.
Chronic: May cause nickel toxicity.
Skin: Acute: May cause irritation.
Chronic: May sensitize the skin (nickel itch). May cause allergic dermatitis, keratitis, eczematous dermatitis and may be accompa-
nied a week later with superficial skin ulcers, which may discharge and become crusted.

Eye: Acute: May cause irritation.
Chronic: May cause conjunctivitis.

Target Organs: May affect the nasal cavities, kidneys, nervous and respiratory system, lungs, blood and skin.
Medical Conditions Generally Aggravated by Exposure: Pre-existing respiratory disorders, pulmonary functions, asthma and skin
disorders.

Signs and Symptoms of Exposure:

Inhalation: May cause a red, dry, sore throat, coughing, shortness of breath, dizziness, headache, nausea, vomiting, diarrhea, cramps,
insomnia and anorexia.
Eye: May cause redness, itching and watering.
Skin: May cause redness, itching, swelling, burning and ulcers.
Ingestion: May cause gastritis, convulsions, asphyxia, giddiness, nausea, headache, cramps, diarrhea and vomiting. Nickel toxicity
may cause: gastroenteritis; Nervous symptoms such as tremor, chorea-like movements and paralysis occur prior to death, which
occurs mostly from heart failure.

Carcinogenicity: NTP? Yes IARC Monographs? Yes OSHA Regulated? Yes

EMERGENCY AND FIRST AID PROCEDURES:

EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms
persist.
SKIN: Remove contaminated clothing; brush material off skin; wash affected area with mild soap and water. Seek medical attention
if symptoms persist.
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.


VI REACTIVITY DATA

Stability: Stable
Incompatibility (Material to Avoid): None recorded

Hazardous Decomposition Products: Fume of nickel and antimony.
Hazardous Polymerization: Will not occur


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: Dispose of in accordance with Local, State and Federal regulations.
VIII SPECIAL PROTECTION INFORMATION

Respiratory Protection: NIOSH - approved dust-mist-vapor cartridge respirator.
Ventilation: Local Exhaust: To maintain exposure below the PEL, TLV. Mechanical (General): Not recommended
Special: Handle in a controlled environment when in dust or powder form.

Protective Gloves: Rubber gloves Eye Protection: Safety Glasses
Other Protective Equipment: Protective gear suitable to prevent contamination.

Work/Hygienic/Maintenance Practices: Implement engineering and work practices 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 thor-
oughly before eating and smoking. Do not blow off clothing or skin with compressed air.


IX SPECIAL PRECAUTIONS

Other Handling and Storage Conditions:

鈥tore in cool, dry area
鈥tore in tightly sealed container
鈥ash thoroughly after handling

Precautions to Be Taken in Handling and Storing: None
Other Precautions: None
