Extinguishing Media Flash Point (Method Used) Flammable Limit N/A N/A N/A Unusual Fire and Explosive Hazards Special Fire Fighting Procedures N/A N/A SECTION 5 - REACTIVITY DATA and HAZARDOUS DECOMPOSITION PRODUCTS Welding fumes and gases cannot be easily classified. The composition ard quantity of the fumes and gases are dependent upon (1) the base metal being welded (2) the welding process and procedure being employed (3) the welding products being used. Other conditions which also influence the composition and quantity of the fume and gases to which employees may be exposed include (1) coatings on the metal being welded (such as paint, plating, galvanizing) (2) the number of welders and volume of the work space (3) the quality and amount of ventilation (4) position of the welder's head relative to the fume plume, and (5) presence of contamination in the atmosphere (such as chlorinated hydrocarbon vapors from cleaning and degreasing). Haynes !-tt'cna1 . Inc. 1 DO A 061440 CONFIDFNTTAl MSDS Welding Products August 15, 1988 Page - 4 - The welding fume of most of these welding products contain certain ingredients which either may, or will, reach their PEL or TLV before reaching the TLV-TWA of 5 mg/m^ defined by ACGIH for general welding fumes. The ingredients of special concern are noted in TABLES 3, 4 and 5, as well as being listed on the product labels. Monitoring the welding fume for these inqredients is recommended. Monitoring for the ACGIH Welding fumes (NOC) is also recommended for all products. INGREDIENTS OF SPECIAL CONCERN - CHROMIUM AND NICKEL: The National Toxicology program (NTP) lists chromium and certain chromium compounds as substances known to be carcinogenic and lists nickel and certain nickel compounds as substances that may reasonably be anticipated to be carcinogens. The International Agency for Research on Cancer (IARC) monogram series designates them as Group 1 and Group 2A, respectively. Many of the welding products covered by this MSDS and the fumes produced during welding contain compounds of chromium and nickel. While certain chromium and nickel compounds have been clearly shown to be animal and human carcinogens, these same compounds have not been found in welding fumes. It is understood that there are no reliable scientific studies which show that stainless steel welders or any welders or workers exposed to alloys containing significant chromium and/or nickel run increased risks of lung cancer because of exposure to the forms of chromium and nickel found in welding fumes. ROUTES OF ENTRY: The major route of entry of the fumes and gases is inhalation. Skin contact may be the cause of dermatitis or allergies, ingestion of material is possible via dirty hand contact with food and mouth. Aggravation of preexisting respiratory allergic conditions may occur in some workers. Some studies have shown a higher level of lung related problems among older workers who smoked than those who did not smoke. Where exposure data are available, they show overexposure to welding fumes. . WELDING GASES: Shielding gases are used with GMA welding and GTA welding, and other gases are produced by the welding action itself. The GASES EXPECTED are listed in TABLE 5, and TA8LE 7 lists the HEALTH EFFECTS RESULTINGTROM ' EXCESSIVE EXPOSURE. HEALTH HAZARD TABLES: TABLE 6 and TABLE 7 show the compounds which have been discussed in other parts of this MSDS, and the compounds which may be encountered during the normal use of Haynes International, Inc. welding products. The compound names and formulas, CAS numbers, and exposure limits are given. Table 7 presents brief descriptions of possible known short term and long term health hazards which may result from overexposure. Detailed health hazards information is not included for the chemicals listed in Table 5 because 1) they are present only as complex combinations with other DO A 061.441 CONFTOFNTTAt MSDS Welding Products / August 15, 1988 Page - 5 - ingredients, and 2) their presence in the welding fumes is expected to be below their PEL or TLV-TWA when the total welding fume reaches its TLV-TWA of 5mg/m3. Among the sources for this information are TSCA list for CAS numbers, NIOSH/OSHA Pocket Guide to Chemical Hazards and ACGIH Documentation of the Threshold Limit Values. SECTION 7 - PRECAUTIONS FOR SAFE HANDLING, and SECTION 8 - CONTROL MEASURES WELDING HAZARDS: Welding hazards are complex. Available accident and health records show that the great majority of the problems result from physical accidents; such as from electric shock or restricted visibility/mobility, physical strains, radii;. ;r, burns (such as "eye f1 ar1'' ' heat burns due to hot metal or spatter, or metal fume fever. Read and understand the manufacturer's instructions .uni precautionary labels on the products. See American National Standard Institute standard Z49.1 "SAFETY IN WELDING AND CUTTING" published by the American Welding Society, PO Box 351040, Miami, FL 33135, and the OSHA publication 2206 (29 CFR 1910) available from the US Government Printing Office, Washington DC 20402. The National Electrical Manufacturers Association publication EW 5-1982 states: Electric arc welding may create one or more of the following health hazards: Fumes and gases can be dangerous to your health. Short-term overexposure to welding fumes may result in discomfort such as dizziness, nausea, or dryness or irritation of nose, throat, or eyes. Arc Rays can injure eyes and burn skin. Electric shock can kill. EXPOSURES: Maintain all exposures below the limits shown in this MSDS, and the precautionary statements on the package and on the product label. U,se industrial hygiene air monitoring to ensure compliance with the recommended exposure limits. ALWAYS USE EXHAUST VENTILATION. VENTILATION: Use enough ventilation, local exhaust at the arc, or both to keep fumes and gases from the worker's breathing zone and the general area. Train welders to keep their heads out of the welding plume. If the fumes are removed by filtration or some other means and the air/gas stream is put back into the room, gases may build up to toxic or asphyxiation levels. Gas build-up should be monitored and if excessive should be removed or reduced to safe levels by some supplementary system and/or reduced by general ventilation. Remember - the shielding gases used with the GMAW and GTAW procscs'-s can displace breathing air and cause asphyxiation in confined work spaces cr unventilated areas. Haynes International, Inc. DO A 061442 CONFTDFNTIAl. MSDS Welding Products August 15, 1988 Page - 6 - RESPIRATORY PROTECTION: Be sure to use a fume respirator or air supplied respirator when welding in confined spaces or where local exhaust or ventilation does not keep exposure below the PEL and TLV limits. EYE PROTECTION: Arcs produce ultraviolet and infrared radiation. Wear a welder's helmet or use a face shield with protective lenses. As a rule start with a lens shade that is too dark to see the weld zone. Then go to a lighter shade (a lower number shade) which gives sufficient view of the weld zone. Do not go below the minimum recommended in ANSI standard Z49.1 mentioned in this MSDS. PROTECTIVE CLOTHING: Wear hand, head and body protection which help to prevent injury from radiation, sparks and electric shock. Refer to ANSI Z49.1 for more information. At a minimum this includes dry welder's gloves and a protective face shield and may include arm protectors, aprons, hats, shoulder protectors as well as dark, substantial clothing. ELECTRIC SHOCK: Welders should be trained to avoid electric shock by maintaining a dry work area, insulating themselves from the workpiece and ground, and not touching live electrical parts. WASTE DISPOSAL: Dispose of fume, flux and weld grinding residues from the work area, or from filters, in accordance with local, state and federal regulations. Refer to this MSDS for information on the possible contents of the collected fumes and other materials. **** Haynes International, Inc. believes this information to be accurate and to reflect the information available at the publication date of this MSDS.
