Hazards (as defined by OSHA 29CFR 1910.1200) may result from fume generated during welding or brazing. Section 1 lists product designations and composition as manufactured. IMPORTANT See Section 6 for information on potential fume hazard resulting from use of the product SECTION 3 - PHYSICAL DATA Solid wire or rod. Rods may be coated with a chemical flux. Flux coating may be white or other colors. SECTION 4 FIRE AND EXPLOSION DATA (Nonflammable) Welding arc, open flame and sparks can ignite combustibles. See ANSI/ASC Z49.1-1983 Section 6. SECTION 5 - HEALTH HAZARD DATA - COPPER BASED WELDING AND BRAZE WELDING ALLOYS Exposure Section 1 lists normal composition of copper based filler metals. Section 6 lists exposure limits for hazardous decomposition products which might be present in fume generated during welding or brazing. Actual exposure should be determined by monitoring fume in the operator's breathing zone. Primary Route of Exposure Inhalation of fume. Pre-existing medical conditions Individuals with impaired pulmonary functions or illness may have symptoms exacerbated by fume irritants. Possible Effects of Exposure Copper and zinc fume may cause metal fume fever. Short term symptoms may include a metallic taste in the mouth, dryness or irritation of the throat followed by coughing, shortness of breath, nausea, fever, body ache, and chills. Long term exposure to welding fume, gases or dust may contribute to pulmonary irritation or pneumoconiosis. Nickel should be considered a possible carcinogen per OSHA 29 CFR 1910.1200. Certain nickel compounds have been implicated based on experience in some nickel refining operations. The specific compounds, however, have not been determined and a direct association between nickel in welding fume and cancer has not been demonstrated. Emergency First Aid - Remove from dust or fume exposure. If breathing has stopped, perform artificial respiration. Summon medical aid immediately. ther Health Considerations Arc Rays from electric arc welding operations can injure eyes and burn skin. Ehct.ic Stock - From arc welding equipment can kill. Heat Rays (Infrared radiation from llame or hot metal) can injure eyes. DO A 061495 CONFIDENTIAL SECTION 6 - REACTIVITY DATA Hazardous Decomposition Products Welding and brazing fumes and gases cannot be classified simply. The composition and quantity of both are dependent upon the metal being brazed or welded, the process, procedures, and filler metals 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 welded (such as paint, plating, or galvanizing), the number of welders and the volume of the work area, the quality and amount of ventilation, the position of the operator's 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). When the filler metal is consumed, the fume and gas decomposition products generated are different in percent and form from the solid wire or rod ingredients listed in Section 1. Fume and gas decomposition products, and not the ingredients in the electrode or wire are important. The concentration of a given fume or gas component may decrease or increase by many times the original concentration in the electrode. Also, new compounds not in the electrode or wire may form. Decomposition products of normal operation include those originating from the base metal and coating, etc., as noted above. Section 1 lists composition of the aluminum wire or rod. The chart below lists those constituents, defined as hazardous, which are likely to be present in the welding fume.

FL 33135 and OSHA Publication 2206 (29CFR1910), U.S. Government Printing Office. Washington. D.C. 20402 for nore detail on many of the following. lentllation Jse enough ventilation, local exhaust at the arc (or flame), or both, to keep the fumes and gases below TLV's in the vorker's breathing zone and the general area. Train the employee to keep his head out of the fumes. See ANSI/ASC 149.1 Section 5. Respiratory Protection Jse respirable fume respirator or air supplied respirator when welding, brazing, or soldering in confined space or where local exhaust or ventilation does not keep exposure below TLV. Eye Protection Wear helmet or use face shield with filter lens of appropriate shade number (see ANSI/ASC Z49.1 - Section 4.2). Provide protection screens and flash goggles, if necessary, to shield others. P~`*tective Clothing . jr head and body protection which help to prevent injury from radiation, sparks, flame, and electrical shock. See ANSI Z49.1. At a minimum this includes welder's gloves and a protective face shield, and may include arm protectors, aprons, hats, shoulder protection, as well as dark substantial clothing. Train the employee not to touch live electrical parts and to insulate himself from work and ground.
