V.  HEALTH HAZARD INFORMATION

Effects of Exposure:

To the best of our knowledge the physical, chemical and toxicological properties of MP35N have not been thoroughly investigated and recorded.

Specialty steel alloys are generally not considered hazardous in the form shipped (solid bars, billets, rods, wire, etc.,) 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:

Chromium:  Ferrochrome 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.

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.

Possible Signs and Symptoms of exposure to Dust, Welding Fume and Gases:  Short Term Exposure:  Metallic taste, nausea, tightness of chest, fever, irritation of eyes, nose, throat and skin, loss of consciousness/death due to welding gases or lack of oxygen.

Carcinogenicity:  Chromium, cobalt-chromium alloys, and nickel have been identified by the IARC and/or the NTP as potential cancer causing agents. 

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION:  Remove to fresh air, if condition continues, seek medical attention.

INGESTION:  Seek medical help if large quantities of material have been ingested.

SKIN:  Remove any contaminated clothing, brush material off of skin, wash carefully with soap and water.

EYE:  Flush with copious amounts of water for 15 minutes, get medical attention.

VI.  REACTIVITY DATA

Stability:  Stable

Conditions to Avoid:  None

Incompatibility (Material to Avoid):  None

Hazardous Decomposition Products:  Metallic oxides

Hazardous Polymerization:  Will not occur

VII.  SPILL OR LEAK PROCEDURES

Steps to be Taken in Case Material is Released or Spilled:  Sweep or scoop up.

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

VIII.  SPECIAL PROTECTION INFORMATION

Respiratory Protection:  If fumes, misting or dust condition occurs and TLV as indicated in Section II is exceeded, provide NIOSH approved respirators.

Ventilation Requirements:  General exhaust is recommended (to keep airborne concentration of dust and fumes below ACGIH-TLV's).  Use local exhaust as required.

Eye Protection:  Recommended approved safety glasses or goggles when working with dusty material.

Gloves:  As required

Other Clothing or Equipment:  As required

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. 

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 of sustained flushing, safety drench shower and facilities for washing.

DOT Regulations:

Hazard Class:         None

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.
