SECTION 3: HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Metallic wire, rod or strip
Odorless
Flash Point: Not Applicable
Danger. Contains CADMIUM AND (IN CASE OF 50N) NICKEL. Avoid creating dust.
SUSPECT CANCER HAZARD - Risk of cancer depends on route, duration and level of exposure. Harmful if inhaled or swallowed.
May cause eye and skin irritation. Prolonged or repeated contact may result in argyria (discoloration) of the eyes, skin, respiratory tract
or other mucous membranes. Prolonged or repeated exposure may cause liver and kidney damage. Not a fire or explosion hazard in
solid form. Finely divided dust may ignite and burn rapidly when mixed with air in the proper proportions. Toxic metal fumes may be
released in a fire situation.
ROUTES OF ENTRY
Eyes? YES Skin? YES Inhalation? YES Ingestion? YES
POTENTIAL HEALTH EFFECTS
EYE CONTACT may cause irritation. SKIN CONTACT may cause irritation. INHALATION may cause excessive CADMIUM
absorption resulting in pulmonary emphysema and/ or kidney dysfunction. INGESTION is harmful. May cause abdominal pain,
nausea, vomiting and diarrhea. COPPER poisoning can result in hemolytic anemia and kidney, liver and spleen damage. NOTE:
Inhalation of fumes may cause a flu-like illness called metal fume fever. Typically metal fume fever begins four to twelve hours after
sufficient exposure to freshly formed fumes. The first symptoms are a metallic taste, dryness and irritation of the throat. Cough and
shortness of breath may occur along with headache, fatigue, nausea, vomiting, muscle and joint pain, fever and chills. The syndrome
runs its course in 24-48 hours. NOTE: The potential health effects described above only apply if dust or fume is formed.
CARCINOGENICITY
NTP? YES IARC? YES OSHA? YES
In evaluating CADMIUM and CADMIUM COMPOUNDS, the International Agency for Research on Cancer (IARC) has
determined that there is sufficient evidence of carcinogenicity to humans (Group 1). SIMILAR CARCINOGENICITY
RESULTS FOR NICKEL. The Occupational Safety and Health Administration (OSHA) and the American Conference of
Governmental Industrial Hygienists (ACGHIG) considers all cadmium and cadmium compounds to be suspect human cancer
hazard (A2). The National Toxicology Program (NTP) lists only cadmium and certain cadmium compounds as substances
which may reasonably be anticipated to be carcinogenic. This product contains one of those cadmium compounds specifically
identified by NTP.
CHRONIC HEALTH HAZARDS
Refer to Potential Health Effects and Carcinogenicity.
Prolonged or excessive exposures may result in argyria, a permanent localized blue-grey discoloration of the eyes, skin or mucous
membranes. Repeated or long-term exposure to CADMIUM or NICKEL, even at relatively low concentrations, may result in kidney
damage and an increased risk of lung cancer.
MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE
May aggravate existing medical conditions, such as respiratory and/or kidney ailments.
Individuals with Wilson鈥檚 Disease are at increased risk of COPPER poisoning.
NOTE: See Section 8 for Exposure Limits Section 11 for Toxicological Information and Section 12 for Ecological Information.
SECTION 4: FIRST AID MEASURES
EYE CONTACT: Flush eyes with plenty of water. If irritation develops, call a physician. SKIN CONTACT: Immediately wash skin
with soap and plenty of water. If irritation persists, call a physician. INHALATION: If exposed to excessive levels of metal fumes,
remove to fresh air and seek medical attention. INGESTION: Procedures normally not needed. If large quantities are ingested, seek
medical advice.
SECTION 5: FIRE-FIGHTING MEASURES
Flash Point: Not Applicable
Auto-Ignition: Not Applicable

UEL: Not Applicable
NFPA HAZARD CLASSIFICATION
Health: 3 Flammable: 0 Reactivity: 0
HMIS HAZARD CLASSIFICATION
Health: 3* Flammable: 0 Reactivity: 0
* Indicates the possibility of chronic health effects. See Chronic Health Hazards in Section 3 for more information.
EXTINGUISHING MEDIA
Use carbon dioxide, chemical foam or dry chemical. Use any means for extinguishing surrounding fire.
SPECIAL FIRE FIGHTING PROCEDURES
Wear NIOSH/MSHA approved positive-pressure self-contained breathing apparatus.
UNUSUAL FIRE AND EXPLOSION HAZARDS
Not a fire or explosion hazard in solid form. Finely divided dust may ignite and burn rapidly when mixed with air in the proper
proportions. Toxic metal fumes may be released in a fire situation.
SECTION 6: ACCIDENTAL RELEASE MEASURES
Contain spillage and scoop up or vacuum. Notification of the National Response Center (800/424-8802) may be required. Refer to
EPA, DOT and applicable state and local regulations for current response information.
Page 2.
It is recommended that each user establish a spill prevention, control and countermeasure plan (SPCC). Such plan should include
procedures applicable to proper storage, control and clean-up of spills, including reuse or disposal as appropriate (see Section:
Disposal Considerations).
**NOTE** In the event of an accidental release of this material, the above procedures should be followed. Additionally, proper
exposure controls and personal protection equipment should be used ( see Section 8: exposure Control/Personal Protection), and
disposal of the material should be in accordance with Section 13: Disposal Considerations.
SECTION 7: HANDLING AND STORAGE
Wash thoroughly after handling. Store in a cool, dry location away from incompatible materials. Avoid contact with any dusts, mists
or fumes resulting from the use of this product. Do not eat, drink, or smoke in work area. Use only with adequate ventilation. NOTE:
Consult the most recent OSHA CADMIUM Standard (1910.1027) and its attachments, appendices, etc., for full requirements, some of
which are not covered in this Material Safety Data Sheet.

Unless otherwise noted, all values are reported as 8-hour Time-Weighted Averages (TWAs) and dust (particulates only). All ACGIH
TLVs refer to the 1995-96 Standards. All OSHA PELs refer to 29 CFR Part 1910 Air Contaminants: Final Rule, January 19, 1989*.
(*NOTE: As a result of the July 7, 1992 decision by the U.S. Circuit Court of Appeals (AFL-CIO v. OSHA) to vacate the 1989 PELs,
OSHA will no longer enforce these new limits and will return to the pre-1989 PELs.)
NOTE: The hazards of all ingredients in this product are not known, however exposure is not expected as the product is in solid form.
The threshold limit values (TLVs) and potential health effects statements are listed for ingredients of the product for which data is
available. However, these statements may not be applicable as the ingredients are in solid form. If dust, powder, or fume is generated
the TLVs and effects of overexposure statements will be applicable.
RESPIRATORY PROTECTION
A NIOSH/MSHA-approved respirator is recommended if dust is generated.
VENTILATION
General; local exhaust ventilation as necessary to control any air contaminants to within their PELs or TLVs during the use of this
product.
PROTECTIVE EQUIPMENT
Refer to ANSI/ASC Z49.1-88 (Safety in Welding, Cutting and Allied Processes), published by the American Welding Society, for
further information on the selection of personal protective equipment. Safety glasses (with side shields). Body protection as necessary
to prevent skin contact.
