V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

This material is generally not considered hazardous in the form shipped (Rod) However, if your process involves grinding, melting, welding, cutting, or any other process that causes a release of dust or fume, hazardous levels of dust or fume of the constituents of this alloy could be generated.  The following is a list of potential health effects for all hazardous elements that are possibly contaminated in this alloy.  Please refer to "Hazardous Ingredients" section for a list of those specified elements contained in this particular alloy.

Health Effects:

Aluminum:  Metal dust and oxide is generally considered a "nuisance" particulate.  May cause irritation of the eyes, nose, and throat in excessive concentrations.

Boron Oxide:  Has caused irritation of the eyes, nose, and skin of experimental animals.  It may have the same effect on humans.   

Chromium:  Ferro chrome alloys have been associated with lung changes in workers exposed to these alloys.

Cobalt:  Fume or dust causes irritation of the nose and throat and may cause an allergic skin rash.  Also has been reported to cause respiratory disease with symptoms ranging from cough and shortness of breath to permanent disability and death.  The symptoms frequently go away when exposure has stopped, but sometimes the symptoms progress after exposure has ceased.

Iron Oxide:  Repeated exposure to iron oxide fume over a period of years may cause x-ray changes of the lungs, but does not cause  the exposed person to become ill.

Manganese:  Inhalation of manganese fume may cause "Metal Fume Fever" with symptoms of chills, fever, nausea, cough, dry  throat, weakness, muscle aches, and a sweet or metallic taste in the mouth.  Prolonged or repeated exposure may affect the nervous system, with difficulty in walking and balancing, weakness or cramps in the legs, hoarseness of the voice, trouble with memory or judgement, unstable emotions or unusual irritability.  The respiratory system may also be affected by a pneumonia like illness with symptoms of coughing, fever, chills, body ache, chest pain and other common signs of pneumonia.

Molybdenum:  Oxides of molybdenum have caused irritation of the eyes, nose, and throat, weight loss, and digestive disturbances in experimental animals.

Nickel:  Fumes are respiratory irritants and may cause respiratory disease.  Skin contact can also cause an allergic skin rash.  Nickel and its compounds have been reported to cancer of the lungs and sinuses.

Titanium Dioxide:  Considered to be a "nuisance" particulate.  Can cause irritation of the eyes, nose, and throat in high  concentrations.  Slight lung changes may occur.

Carcinogenic References:  Chromium, cobalt-chromium alloys, and nickel have been identified  by the international agency for  research on cancer (IARC) and/or the National Toxicology program (NTP) as potential cancer causing agents.

Exposure Routes:  Exposure to specialty steel alloys occurs primarily from inhalation of dust or fumes.  However, constituents of these alloys may cause effects directly upon the skin or eyes.  Certain constituents may also be harmful if swallowed.

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION:  Move person to fresh air until recovered, consult a physician.

INGESTION:  While ingestion of large enough quantities to cause health effects is unlikely, consult a physician if it occurs.

SKIN:  Wash with water and mild detergent, consult a physician.

EYES:  Flush thoroughly with water, consult a physician.

VI.   REACTIVITY DATA

Stability:  Stable

Conditions to Avoid:  None

Incompatibility (Material to Avoid):  None

Hazardous Decomposition Products:  None

Hazardous Polymerization:  Will not occur.

VII.   SPILL OR LEAK PROCEDURES

Steps to be Taken in Case Material is Released or Spilled:  Product is a solid metal as shipped, no potential for spill or leak.

Waste Disposal Method:  In accordance with Local, State and Federal Waste Disposal Regulations.

VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection:  If your process causes a release of dust or fume n the excess of the permissible exposure limit, NIOSH  approved respirators for protection against airborne dust or fumes should be worn.  Respirators should be used in accordance with 29CFR 1910.134.

Ventilation:  If your process causes a release of dust or fume, use local and general exhaust ventilation to keep airborne concentration of dust or fumes below the TLV.

Protective Equipment:  Gloves and barrier creams may be necessary to prevent skin sensitization and dermatitis.  If your process  involves grinding or any other action that causes the release of dust or fumes, approved safety glasses or goggles should be worn.

X.   SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and Storage:  Store in a cool, dry area.  Wash thoroughly after handling.

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 or skin with compressed air.  Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.

The above information is believed to be correct, but does not purport to be all inclusive and shall be used only as a guide.  ESPI shall not be held liable for any damage resulting from handling or from contact with the above product.
