| Those involved with the welding industry are obligated
to provide safe working conditions and be aware of the potential hazards
associated with welding fumes, gases, radiation, electrical shock, heat,
eye injuries, burns, etc. Various local, municipal, state and federal regulations
(OSHA, for example) relative to the welding and cutting processes must
be considered.
Nickel-, cobalt-, and iron-base alloy products may contain, in varying concentrations, the following elemental constituents: aluminum, cobalt, chromium, copper, iron, manganese, molybdenum, nickel and tungsten. For specific concentrations of these and other elements present, refer to the Material Safety Data Sheets (MSDS) H2071-4 and H1072 for the product. (H2071-4 replaces H3095). The operation and maintenance of welding and cutting equipment should conform to the provisions of American National Standard ANSI Z49.1-88, "Safety in Welding and Cutting". Attention is especially called to Section 4 (Protection of Personnel), Section 5 (Ventilation) and Section 7 (Confined Spaces) of that document. Adequate ventilation is required during all welding and cutting operations. Specific requirements are included in Section 5 for natural ventilation versus mechanical ventilation methods. When welding in confined spaces, ventilation shall also be sufficient to assure adequate oxygen for life support. The following precautionary warning, which is supplied with all welding products, should be provided to and fully understood by all employees involved with welding. Caution Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases. Use adequate ventilation. See ANSI/AWS Z49.1-88, "Safety in Welding and Cutting" published by the American Welding Society. EXPOSURES: Maintain all exposures below the limits shown in the Material Safety Data Sheet, and the product label. Use industrial hygiene air monitoring to ensure compliance with the recommended exposure limits. ALWAYS USE EXHAUST VENTILATION . 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. WARNING: Protect yourself and others. Be sure the label is read and understood by the welder. FUMES and GASES can be dangerous to your health. Overexposure to fumes and gases can result in LUNG DAMAGE. ARC RAYS can injure eyes and burn skin. ELECTRIC SHOCK can kill. |
