Extinguishing Media: Use suitable extinguishing media for surrounding materials or type of fire.
Special Firefighting Procedures: Firefighters must wear full face, self-contained breathing apparatus with full protective clothing to
prevent contact with skin and eyes. Fumes from fire are hazardous. Isolate runoff to prevent environmental pollution.
Unusual Fire and Explosion Hazards: When heated to decomposition, nickel sulfide may emit toxic fumes of oxides of sulfur.
V HEALTH HAZARD INFORMATION
Routes of Entry: Inhalation, ingestion, skin and eyes.
Effects of Exposure:
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. Hypersensitivity to
nickel is common and can cause allergic contact dermatitis, pulmonary asthma, conjunctivitis and inflammatory reactions around
nickel containing medical implants and prosthesis.
Sulfides have variable toxicity. Sulfides of the heavy metals are generally insoluble and hence have little toxic action except
through the liberation of hydrogen sulfide.
Inhalation: May cause mild poisoning, shortness of breath, congestion of the lungs, irritation to the upper respiratory tract, mucous
membranes and nasal cavities. May cause pulmonary asthma attacks.
Ingestion: Large doses may cause intestinal disorders, convulsions and asphyxia.
Skin: May cause irritation.
Eye: May cause irritation.
Inhalation: Prolonged or repeated inhalation may cause pneomitis.
Ingestion: May cause nickel toxicity.
Skin: 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: May cause conjunctivitis.
Target Organs: May affect the nasal cavities, respiratory system, lungs, blood and skin.
Medical Conditions Generally Aggravated by Exposure: Pre-existing respiratory disorders, pulmonary functions, asthma and skin
Carcinogenicity: NTP: Yes IARC: Yes OSHA: Yes
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 any contaminated clothing, brush material off skin, wash affected area with mild soap and water. Seek medical
attention if symptoms persist.
EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms
VI REACTIVITY DATA
Conditions to Avoid: None
Incompatibility (Materials to Avoid): Oxidizing agents, strong acids and bases.
Hazardous Decomposition Products: Oxides of sulfur.
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. 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 Federal, State and Local regulations.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection: NIOSH approved dust-mist-vapor respirator.
Ventilation: Use local exhaust to maintain concentration at or below the PEL, TLV. General exhaust is also recommended.
Protective Gloves: Rubber gloves Eye Protection: Safety glasses
Other Protective Clothing or Equipment: Protective gear suitable to prevent contamination.
IX SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: Store in a tightly sealed container in a cool, dry area. Wash thoroughly after
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.
Som e of the chemicals listed herein are research or experimental substances which may be toxic, as defined by various
governmental regulations. In accordance with Environmental Protection Agency 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).
