October 1988SECTION I - IDENTIFICATIONManufacturer/Supplier:The Lincoln Electric Company22801 St. Clair AvenueCleveland, OH 44117-1199(216) 481-8100Product Type: Stainless Steel WiresProducts: Blue Max MIG 308LSi, 309LSi, 316LSi , 308L N, 309L N, 316L N, Blue Max Orbital TIG 308L N, Blue Max Orbital TIG 308L, Blue Max Orbital TIG 309L N, Blue Max Orbital TIG 309L, Blue Max Orbital TIG 316L N, Blue Max Orbital TIG 316L, Blue Max Orbital TIG 4462 N, Blue Max Orbital TIG 320LR NSECTION II - HAZARDOUS MATERIAL (1)I M P O R T A N T !This section covers the materials from which this product is manufactured. The fumes and gases produced during welding with the normal use of this product are covered by Section V; see it for industrial hygiene information.CAS Number shown is representative for the ingredients listed.(1) The term “hazardous” in “Hazardous Materials” should be interpreted as a term required and defined in the Hazards Communication Standard and does not necessarily imply the existence of any hazard. All materials are listed on the TSCA inventory.Product is inert, no special handling or spill procedures required. Not regulated by DOT.Rev 11/06b (CONTINUED ON SIDE TWO)Product: Blue Max Stainless WiresDate: 3/20/2013SECTION IV - HEALTH HAZARD DATAThreshold Limit Value: The ACGIH recommended general limit for Welding Fume NOS - (Not Otherwise Specified) is 5 mg/m3.ACGIH-1999 preface states that the TLV-TWA should be used as guides in the control of health hazards and should not be used as fine lines between safe and dangerous concentrations. See Section V for specific fume constituents which may modify this TLV. Threshold Limit Values are figures published by the American Conference of Government Industrial Hygienists. Units are milligrams per cubic meter of air.Effects of Overexposure: Electric arc welding may create one or more of the following health hazards:Fumes and Gases can be dangerous to your health. Common entry is by inhalation. Other possible routes are skin contact and ingestion.Short-term (acute) overexposure to welding fumes may result in discomfort such as metal fume fever, dizziness, nausea, or dryness or irritation of nose, throat, or eyes. May aggravate pre-existing respiratory problems (e.g. asthma, emphysema). Chromates present in the fume have beenknown to cause severe irritation of the bronchial tubes and lungs. Asthma has been reported.Long-term (chronic) overexposure to welding fumes can lead to siderosis (iron deposits in lung) and may affect pulmonary function. Manganese overexposure can affect the central nervous system, resulting in impaired speech and movement. Bronchitis and some lung fibrosis have been reported. Nickel and its compounds are on the IARC (International Agency for Research on Cancer) and NTP (National Toxicology Program) lists as posing a cancer risk to humans. Nickel compounds are skin sensitizers with symptoms usually occurring after repeated exposure - ranging from a slight itch to severe dermatitis. Chromates may cause ulceration and perforation of the nasal septum. Liver damage and allergic reactions, including skin rash, have been reported. Chromates contain the hexavalent form of chromium. Hexavalent chromium and its compounds are on the IARC (International Agency for Research on Cancer) and NTP (National Toxicology Program) lists as posing a cancer risk to humans.WARNING: This product contains or produces a chemical known to the State of California to cause cancer and birth defects (or other reproductive harm). (California Health & Safety Code Section 25249.5 et seq.)Arc Rays can injure eyes and burn skin. Skin cancer has been reported.Electric Shock can kill. If welding must be performed in damp locations or with wet clothing, on metal structures or when in cramped positions such as sitting, kneeling or lying, or if there is a high risk of unavoidable or accidental contact with workpiece, use the following equipment: Semiautomatic DC Welder, DC Manual (Stick) Welder, or AC Welder with Reduced Voltage Control.Emergency and First Aid Procedures: Call for medical aid. Employ first aid techniques recommended by the American Red Cross.IF BREATHING IS DIFFICULT give oxygen. IF NOT BREATHING employ CPR (Cardiopulmonary Resuscitation) techniques.IN CASE OF ELECTRICAL SHOCK, turn off power and follow recommended treatment. In all cases call a physician.SECTION V - REACTIVITY DATAHazardous Decomposition Products: Welding fumes and gases cannot be classified simply. The composition and quantity of both are dependent upon the metal being welded, the process, procedure and electrodes 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 worker area, the qualityand amount of ventilation, the position of the welder's head with respect to the fume plume, as well as the presence of contaminants inthe atmosphere (such as chlorinated hydrocarbon vapors from cleaning and degreasing activities.)When the electrode is consumed, the fume and gas decomposition products generated are different in percent and form from theingredients listed in Section II. Decomposition products of normal operation include those originating from the volatilization, reaction,or oxidation of the materials shown in Section II, plus those from the base metal and coating, etc., as noted above.Reasonably expected fume constituents of this product would include: Primarily iron oxide, manganese oxide, and complex chromium oxides;secondarily complex oxides of copper, molybdenum and nickel when used with gas shielding.Maximum fume exposure guideline for this product based on manganese content is 0.1 milligrams per cubic meter when used with gas shielding.The OSHA PEL (Permissible Exposure Limit) is a ceiling value that shall not be exceeded at any time.Keep exposure as low as possible. Indoors, use local exhaust; outdoors, a respirator may be required.Gaseous reaction products may include carbon monoxide and carbon dioxide. Ozone and nitrogen oxides may be formed by the radiationfrom the arc.Determine the composition and quantity of fumes and gases to which workers are exposed by taking an air sample from inside the welder's helmet if worn or in the worker's breathing zone. Improve ventilation if exposures are not below limits. See ANSI/AWS F1.1, F1.2, F1.3 and F1.5, available from the American Welding Society, 550 N.W. LeJeune Road, Miami, FL 33126.SECTION VI AND VIICONTROL MEASURES AND PRECAUTIONS FOR SAFE HANDLING AND USE Read and understand the manufacturer's instruction and the precautionary label on the product. Request Lincoln Safety Publication E205. See American National Standard Z49.1, "Safety In Welding, Cutting and Allied Processes" published by the American Welding Society, 550 N.W. LeJeune Road, Miami, FL, 33126 (both available for free download at /community/safety/) and OSHA Publication 2206 (29CFR1910), U.S. Government Printing Office, Superintendent of Documents, P.O. Box 371954, Pittsburgh, PA 15250-7954 for more details on many of the following: Ventilation: Use enough ventilation, local exhaust at the arc, or both to keep the fumes and gases from the worker's breathing zone and the general area. Train the welder to keep his head out of the fumes. Keep exposure as low as possible.Respiratory Protection: Use respirable fume respirator or air supplied respirator when welding in confined space or general work area when local exhaust or ventilation does not keep exposure below TLV.Eye Protection: Wear helmet or use face shield with filter lens shade number 12 or darker. Shield others by providing screens and flash goggles. Protective Clothing: Wear hand, head, and body protection which help to prevent injury from radiation, sparks and electrical shock. See 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 welder not to permit electrically live parts or electrodes to contact skin or clothing or gloves if they are wet. Insulate from work and ground.Disposal Information:Discard any product, residue, disposable container, or liner as ordinary waste in an environmentally acceptable manner accordingto Federal, State and Local Regulations unless otherwise noted.

Such materials are those consisting entirely of steel, iron, brick, tile, concrete, slate, glass or plasters, or any combination thereof.Materials that are reported as passing ASTM E 136, Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750°C shall be considered non-combustible materials.CombustibleMaterials made of or surfaced with wood, compressed paper, plant fi bers, plastics, or other material that can ignite and burn, whether fl ame proofed or not, or plastered or unplastered shall be considered combustible materials.Non-Combustible Cement BoardThe L3 Linear fi replace requires a 1/2” (13 mm) thicknon-combustible cement board to be used as a wall surface immediately surrounding the unit’s opening—see diagram for minimum coverage.Extending the cement board well beyond the minimum shown will help avoid cracking due to di ff erential expansion of materials.Pre-drill cement board with oversized holes and do not over-tighten screws to avoid cracking due to heat expansion.Standard gypsum wall board may be used beyond the perimeter of the cement board.Minimum coverage area of non-combustible cement board.inches [mm]With 1850 or 1875 trimswith 1830CIK kitA Min. 25-1/2 [648]Min. 25-1/8 [638]B 14-3/4 [375]15-13/16 [401]C Min. 9-1/4 [235]Min. 8-9/16 [218]D Min. 5-1/16 [129]Min. 4-1/2 [114]EMin. 64 [1626]Min. 65-1/4 [1657]Wall Finish — TrimsWider trim (1850) can adjust up to 1” forward of surface of cement board.Cement board tucks behind trim.Narrow trim (1875) can adjust up to 5/8” forward of surface of cement board.Cement board tucks behind trim.Clean Installation Kit 1830CIK requires HeatShift. Cement board fi nishes up to perimeter of frame. Must install BEFORE cement board.Non-Combustible Finishing Over Cement BoardAdditional non-combustible material such as tile, etc., may be applied over top of the cement board or you may choose to leave it fi nished clean with no tile, etc.Be aware that a trim is always required. Finish should not cover the trims.1875 and 1850 TrimsOnly the 1875 and 1850 style trims will accept tile, etc. tucked behind them (up to 5/8” thick for the 1875 and up to 1 inch thick for the 1850).1830 Trim1830 trim must be installed BEFORE cement board. Cement board and fi nishes are applied to the perimeter of the trim frame. Cement board and fi nish CANNOT betucked under this trim.Wall Finish — Avoid CrackingAvoiding Cracking Wall FinishesWe recommend installing the optional HeatShiftSystem to reduce the wall temperatures and minimize the possibility of cracking wall fi nishes.If a clean fi nish with no tile, etc. is desired, joints in the cement board and the transition to gypsum board will require special attention if future cracking is to be controlled. Be aware that temperatures on the non-combustible wall surface above the appliance can exceed 200°F (93°C).Below are some tips on how to best avoid any cracking:• Allow materials to dry thoroughly before fi nishing the wall. Cement board has the ability to absorb up to 30 percent of its weight in water and may shrink as much as 1/8” over a 48” length when drying from a satu-rated condition. Running the fi replace for an extended period before fi nal fi nishing will help drive out mois-ture.• Always pre-drill screw holes through cement boardand use screws speci fi c for material used.• Always use mesh tape over joints.• Always stagger joints in wall board.• Behind joints, double up studs or use studs “on the fl at” to add extra support to the joint. Adhesive on the backside of wall board behind any joints can help control di ff erential movement.• Use multiple, thinner coats of joint compound and al-low to dry thoroughly between coats.• Ensure framing materials are dry.• After fi nishing the wall, introduce heat gradually to slowly dry any excess moisture rather than drying too fast.• Avoid notching cement board or tiles around corners of window opening and instead provide a joint that intersects the corner.• Avoid using lage one-piece slab of material with a cut-out in the middle as a surround for the fi replace.Expansion above the opening will cause cracking at in-side corners. Provide a joint that intersects the insidecorner to avoid cracking.。
