V. HEALTH HAZARD INFORMATION

Effects of Exposure:

We do not consider this product in the form it is sold to constitute a physical hazard or a health hazard. Subsequent operations such as abrading, melting, welding, cutting or processing in any other fashion may produce potentially hazardous dust or fumes which can be inhaled, swallowed, or come in contact with the skin or eyes.

No toxic effects would be expected from exposure to the solid form of this metal. Prolonged repeated exposure to fumes or dusts generated during heating, cutting, brazing or welding may or may not cause adverse health effects associated with the listed constituents in excess of OSHA permissible exposure limits.

Chronic Effects:

There are no adverse effects from the product in it’s solid form. Adverse effects may or may not result from long-term (chronic) exposure to dust, fume, gases, etc., that occur by way of subsequent operations on the product. Some studies would associate one (or more) of the constituents (per Section II) with the potential for neurologic, pulmonary, respiratory, skin or other disease. Chromium, cobalt and nickel in various chemical compounds have been identified as suspect human carcinogens by the IARC, NTP Annual Report. We believe there are no reliable scientific studies which show that workers exposed to operations upon this alloy suffer increased incidence of lung cancer or other disease because of their exposure to the forms of chromium, nickel or their elements in this product.

Important: Determine actual exposure by industrial hygienic monitoring.

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.

Primary Routes of Entry: Inhalation, Eye Contact, Skin Contact, Ingestion.

Medical Conditions Generally Aggravated by Exposure: Aggravation of pre-existing respiratory or allergic conditions may occur in some workers.

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult, 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.

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

VI. REACTIVITY DATA

Stability: Stable

Conditions to Avoid: None known

Incompatibility (Material to Avoid): Reacts with strong acids to generate hydrogen gas and may produce hexavalent chromium.

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 up and place in a container for disposal. Take care not to raise dust.

Waste Disposal Method: Solids: Sell as scrap for reuse. Dust, etc: 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.

Protective Gloves: As required

Other Clothing or Equipment: As required

IX. SPECIAL PRECAUTIONS

Precautions to be Taken in Handling and Storage: No special precautions necessary for material in solid form. Material in powdered form should be stored in a tightly sealed container in a cool, dry area. Wash thoroughly after handling.

Work Practices: Use good housekeeping practices to prevent accumulations of dusts and to keep airborne dust concentrations at a minimum. This material is potentially contaminated with coatings such as oils for preservatives and other contaminants. If the material is contaminated, special precautions (such as process control and personal protective equipment appropriate to the nature of the suspected contaminants) should be taken to avoid resulting exposures when handling, cutting (thermal or mechanical) and/or heating or melting.
