V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

Under normal handling and use, exposure to massive forms of nickel presents few health hazards.  If, however, massive forms are converted to particulates, then both acute and chronic health hazards are possible.  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, pulmonary asthma, conjunctivitis and inflammatory reactions around nickel containing medical implants and prosthesis (Sax, Dangerous Properties of Industrial Materials).

Iron compounds have varying toxicity.  Some iron compounds are suspected carcinogens.  In general, ferrous compounds are more toxic than ferric compounds.  Acute exposure to excessive levels of ferrous compounds can cause liver and kidney damage, altered respiratory rates and convulsions.  (Sax, Dangerous Properties of Industrial Materials).

In animals, inhalation of copper dust has caused hemolysis of the red blood cells, deposition of hemofuscin in the liver and pancreas, and injury to the lung cells; injection of the dust has caused cirrhosis of the liver and pancreas, and a condition closely resembling hemochromatosis or bronzed diabetes (Sax, Dangerous Properties of Industrial Materials).

Chromium is a confirmed carcinogen with experimental tumorigenic data.  Human poison by ingestion with gastrointestinal effects.

Acute Effects:

Inhalation:  Exposure to high concentrations of metallic fumes or dusts may result in irritation of the respiratory tract and/or sensitization of the lungs and other mucous membranes.  Excessive inhalation of fumes from many metals can produce an acute reaction known as ‘metal fume fever’.

Ingestion:  Ingestion of harmful amounts of product as distributed is unlikely due to its solid, insoluble form.  Ingestion of dust may cause nausea and/or vomiting.  Serious effects may occur if large amounts of dust are swallowed.

Skin:  Exposure to dust may cause irritation or sensitization, possibly leading to dermatitis.

Eyes:  Exposure to high concentrations of fumes or dusts may cause irritation and/or sensitization.

Chronic Effects:

Inhalation:  May cause allergic sensitization and asthma, lung inflammation, pneumonitis, pneumonia, bronchitis, siderosis (benign lung disease caused by inhaling iron particles), diffuse pulmonary fibrosis, nasal perforation and nasal cavity damage.

Ingestion:  Large or repeated doses may cause central nervous system damage, possibly permanent, liver damage, gout and inflammation of the joints.

Skin:  May cause dermatitis.

Eyes:  May cause eye inflammation.

CarcinogenicityNTP:  Yes    IARC:  Yes    OSHA:  Yes

 

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION:  Remove 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, wash affected area with mild soap and water.  If irritation persists, seek medical attention.

EYE:  Flush eyes, including under upper and lower eyelids, with lukewarm water.  If irritation persists seek medical attention.

 

 

VI.   REACTIVITY DATA

Stability:  Stable

Conditions to Avoid:  N/A

Incompatibility (Material to Avoid):  N/A

Hazardous Decomposition Products:  At temperatures above the melting point metallic oxide fume may be formed.

Hazardous Polymerization:  Does not occur.

 

 

VII.   SPILL OR LEAK PROCEDURES

Steps to be Taken in Case Material is Released or Spilled:  For solid forms of the material no special steps necessary.  For processes that produce dust, wear appropriate respiratory and protective equipment specified in Section VIII-Special Protection Information.  Isolate spill area, provide ventilation and extinguish sources of ignition.  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 Local, State and Federal regulations.

 

 

VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection:  If your process causes a release of dust of fume in excess of PEL, NIOSH approved respirators should be worn in accordance with 29CFR 1910.134.

Ventilation:  Use adequate ventilation to keep fume or dust concentration below the occupational exposure limits shown in section II.

Protective Equipment:  If your process causes a release of dust or fume, approved safety glasses or goggles should be worn.  Gloves are recommended.

 

 

IX.   SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and Storage:  No special storage precautions are required for material in solid form.  Store in a cool, dry area.

Other Precautions:  Avoid breathing of and contact with fumes and dusts during processing.

Work Practices:  Implement engineering and work practice controls to reduce and maintain concentration of exposure.  Use good housekeeping and sanitation practices.  Do not use tobacco or food in work area.  Wash thoroughly before eating or smoking.  Do not blow dust off clothing or skin with compressed air.  Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.
