When the material is consumed, fume and gas decomposition products generated are different in percent and form from the
ingredients listed in Section 3. Fume and decomposition products, not the ingredients in the rod, are important. Decomposition
products include those originating from the volatilization, reaction, or oxidation of materials in Section 3, plus those from the base
metal and coating, etc., as noted above. These components are virtually always present as complex oxides and not as metals
(Characterization of Arc Welding Fume: American Welding Society). The following limits can be used as guidance. Refer to
Section 11 for more information about welding fumes.

MONITOR FUME LEVELS. One recommended way to determine the composition and quantity of fumes and gas to which
workers are exposed is to take an air sample in the worker's breathing zone (see ANSI/AWS F1.1, F1.2, F1.3, F1.4, and F1.5,
available from the "American Welding Society," 550 N.W. LeJeune Road, Miami, FL 33126).
Gaseous reaction products may include carbon monoxide and carbon dioxide.
SECTION 9: PHYSICAL AND CHEMICAL PROPERTIES
Appearance: bare solid rod pH-Value: not applicable
Boiling point: not applicable Flash point: not determined
Working Temperature: approx. 710 °F (375 °C)
SECTION 10: STABILITY AND REACTIVITY
GENERAL: These items are only intended for soldering applications.
STABILITY: Product is chemically stable and non-reactive.
INCOMPATIBILITY / CONDITIONS TO AVOID: Keep product away from high heat and moisture.
MATERIALS TO AVOID: Strong acids, strong oxidizers, some halogenated compounds.
HAZARDOUS POLYMERIZATION: Will not occur.
REACTIVITY: None.
HAZARDOUS DECOMPOSITION OR BY-PRODUCTS: Metallic oxides. Fumes can be dangerous to your health. See Section 11
NOTE: In other countries the exposure limits listed in Section 3 may be different and the appropriate country standards should be
used.
SECTION 11: TOXICOLOGICAL INFORMATION
Threshold Limit Value: The ACGIH recommended general limit for welding fume NOS (not otherwise specified) is 5 mg/m³.
The ACGIH 1999 preface states: "The TLV-TWA should be used as guides in the control of health hazards and should not be used
as firm lines between safe and dangerous concentrations." See Section 8 for specific fume constituents that may modify the TLV.
Brazing/soldering/welding vapors and fumes from brazing/soldering/welding may cause metal fume fever. Symptoms can appear 4
to 12 hours after (headache, dizziness, dryness, cough, nausea and fever).
