                                    SECTION IV (FIRE AND EXPLOSION HAZARD DATA)

Non-Flammable: Flames used for brazing or soldering can ignite combustibles. Refer to American National Standard Z49.1 for fire

prevention during welding/brazing. These products as shipped are non-hazardous, nonflammable, non-explosive, and non-reactive.

Rating under National Fire Protection 704: Health, 1: Flammability, 0: Reactivity, 1.



                                SECTION V (REACTIVITY DATA)

STABILITY: Stable

CONDITIONS TO AVOID: Excess heat

INCOMPATIBILITY (conditions to avoid): Acetic anhydride, alkali or alkali earth metals, zirconium, platinum, bromine trifluoride.

HAZARDOUS COMBUSTION OR DECOMPOSITION PRODUCTS: Boron oxide, boron trifluoride, and/or hydrogen fluoride.

HAZARDOUS POLYMERIZATION: Will not occur.



When flux is consumed during brazing / soldering, the fumes cannot be classified simply. The composition and quantity of both are

dependent upon the metal being brazed / soldered, the process, procedure, and filler metal used. Other conditions which also influence

the composition and quantity of the fumes and gases to which workers may be exposed include: coatings on the metal being soldered

(such as paint, plating or galvanizing), the number of workers and volume of the work area, the quality and amount of ventilation,

position of workers� head with respect to the fume plume, as well as the presence of contaminants in the atmosphere (such as chlorinated

hydrocarbon vapors from cleaning and degreasing activities).

MSDS: 16 B Flux                                                                                                              Page 2 of 3

When the material is consumed, fume and gas decomposition products generated are different in percent and form from the ingredients

listed in Section II. Fume and gas decomposition products, not the ingredients in the flux, are important. Decomposition products

include those originating from the volatilization, reaction, or oxidation of the materials shown in Section II plus those from the base

metal, 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).



Gaseous reaction products may include carbon monoxide and carbon dioxide. 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).



                                            SECTION VI (HEALTH HAZARD DATA)

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 V for specific fume constituents that may modify the TLV.



FUMES AND GASES can be dangerous to your health.

PRIMARY ROUTE OF ENTRY is the respiratory system. Other possible routes are eyes, ingestion, and/or skin contact.

PREEXISTING respiratory or allergic conditions may be aggravated in some individuals (i.e. asthma, emphysema).



SHORT TERM (ACUTE) OVEREXPOSURE: irritation to the nose, throat and respiratory tract; cough, nose bleeds, nausea,

vomiting, chest tightness, chills, fever, tearing, pneumonitis, pulmonary edema. FLUORIDES - Fluoride compounds produced may

cause eye and skin burns, and pulmonary edema bronchitis. Exposure to extremely high levels of fluorides can cause abdominal pain,

diarrhea, muscular weakness, and convulsions. In extreme cases it can cause loss of consciousness and death.



LONG-TERM (CHRONIC) OVEREXPOSURE: Irritation of skin, abdominal pain, cramps, liver and kidney damage, impaired

pulmonary function. Prolonged absorption of BORON COMPOUNDS may cause mild gastrointestinal irritation, loss of appetite,

nausea, and erythematous rash. Dryness of skin and mucous membranes, loss of hair, conjunctivitis, and kidney injury have also been

observed. Reproductive effects have been observed in laboratory animals. Primary route of entry is the respiratory system.

FLUORIDES - Overexposure to fluorides can cause serious bone erosion, excessive calcification of the bone and calcification of the

ribs, pelvis and spinal column. Exposure to fluorides may cause skin rash.



EMERGENCY & FIRST AID PROCEDURES: Call for medical aid. Employ first aid techniques recommended by The American

Red Cross.

        Swallowing - Call a physician at once or your Poison Control Center. Advise of Section II immediately.

        Skin - Promptly flush with water to remove all residue. If rash or burn develops, consult a physician.

        Inhalation - Remove to fresh air.

        Eyes - Flush with water for at least 15 minutes to remove all residue. Get medical attention.



CARCINOGENICITY

WELDING FUMES (not otherwise specified) are considered to be carcinogenic defined with no further categorization by

NIOSH and IARC.





        SECTION VII (PRECAUTION FOR SAFE HANDLING AND USE/APPLICABLE CONTROL MEASURES)

Read and understand the manufacturer's instructions and precautionary label on this product.

See American National Standard Z49.1, Safety in Welding and Cutting, published by the "American Welding Society," 550 N.W.

LeJeune Road, Miami, FL 33126 and OSHA Publication 2206 (29CFR 1910), U.S. Government Printing Office, Superintendent of

Documents, P.O. Box 371954, Pittsburgh, PA 15250-7954 for more detail on the following:



Ventilation: Use enough ventilation, local exhaust at the arc, or both, to keep the fumes and gases below the TLV's in the workers

breathing zone and the general area. Train the welder to keep his head out of the fumes. Monitor fume levels and do not exceed permissible

exposure limits or values.

Respiratory Protection: Use respirable fume respirator or air supplied respirator when brazing/welding in a confined space or where

local exhaust or ventilation does not keep exposure below the TLV's.

Eye Protection: Wear appropriate brazing safety goggles.

Protective Clothing: Wear head, hand, and body protection that help to prevent injury; including rubber apron and rubber gloves. See

ANSI Z49.1.

Waste: Spill or release: Clean up and flush remaining material with lots of water. Dispose of any waste residues in accordance with EPA

or local regulations.

Storage: Keep material sealed and away from heat.
