SECTION V FIRE AND EXPLOSION DATA Nonflammable, however, arcs, sparks, and molten metal can ignite flammables and combustibles or cause explosions. SECTION VI REACTIVITY DATA Welding and hot cutting fumes and gases cannot be classified simply. Their composition and quantity are dependent on the metal being welded, the procedures, processes and the type of wire or electrodes used. Other influencing factors are the presence of contaminants in the atmosphere. Decomposition products from the welding or cutting operation include those from the volatilization, reaction and/or oxidation of the materials in Section III and may include oxides of the metals, chromates, flourides and complex metallics. Gaseous reaction products may include carbon monoxide, ozone and nitrogen oxides. Chlorinated solvents may be decomposed into toxic gases such as phosgene.

Some elements or compounds will exceed their PEL's/TLV's before the total fumes exceed 5 mg/m\ SECTION VH HEALTH HAZARD OATA ***This Product Poses No Health Hazard As Shipped*** But May Pose A Health Hazard During Use. Electric arc welding rays can injure eyes and burn skin. Dust, fumes and gases can be dangerous to your health. Lung damage may result from overexposure. Sections II. Ill and VI list specific hazardous ingredients, reaction products and OSHA PEL'S and ACGIH TLV's. AGGRAVATION Some workers may experience discomfort at concentrations below the threshold limit values and others may be affected by a pre existing condition or other occupational illness because of the wide variation in individual susceptibilities. PRIMARY ROUTE OF ENTRY Fumes, gases and dust can be a health hazard thru inhalation. ACUTE EXPOSURE Short term exposure to welding fumes, gases or dust may result in discomfort such as dizziness, nausea, fever, dryness and/or irritation of nose, throat and eyes. Skin sensitivity may also be noted. Acute exposure can result in the same symptoms except to a greater degree as well as watery eyes, headache, breathing difficulty, frequent coughing and/or chest pains. Some toxic gases may cause pulmonary edema, asphyxiation and excessive exposure can be fatal. CHRONIC EXPOSURE Chronic exposure may result in neurological damage, lung fibrosis, pneumoconiosis and other lung diseases. Nickel and Chromium are considered possible carcinogens under OSHA (29CFR 1910-1200.) The studies forming the basis for this classification were from operations other than welding of Chromium or Nickel. There is considerable controversy on the extent of the respiratory cancer problems due to nickel and chromium. In addition a small amount of silica is also present and it is listed as a probable carcinogen. Nevertheless exposures must be maintained below the levels specified in Section II and IV.

INHALATION: Remove fresh air. If breathing is difficult administer oxygen If not breathing begin artificial respiration. If no detectable pulSt begin external heart massage. SKIN: Wash affected area with soap and water. EYES: Flush with large amounts of fresh water for at least 15 minutes. INGESTION: Seek medical attention. *ln all cases, seek medical attention for first aid.*** SECTION vn - PRECAUTIONS FOR SAFE HANDLING AND USE vehthaton Use enough ventilation when cutting, grinding or welding to keep the dust, fumes and gases from the workers breathing zone and general area. Keep exposure below the limits specified in Sections III and VI. RESPIRATORY PROTECTION Use weld fume respirator or air supplied respirator when cutting, grinding or welding in a confined space or where local exhaust or general ventilation does not keep exposure below recommended limits. Monitor the air quality inside the welder's helmet, if worn, and/or the worker's breathing zone to determine if a respirator is required and the type needed. Use only NIOSH approved respirators. EYE PROTECTION Use OSHA approved goggles, glasses and/or face shield when cutting, grinding or welding. In addition, when hot cutting or welding, wear welding helmet or face shield with filter lens. Select welding lens shade from American Welding Society (AWS) publication F2.2. PROTECTIVE CLOTHING Wear gloves and flame retardant clothing when cutting, grinding or welding. Do not expose skin to radiation when hot cutting or welding. Provide protective screens to shield others. SPILLS, LEAKS AND WASTE DISPOSAL Clean up any grinding dust or waste residues and place in suitable Department of Transportation (DOT) approved containers and dispose of in full compliance with federal, state and focal regulations. Avoid inhalation and skin exposure.
