For specific concentrationsof these and otherelements present, refer to theMaterial Safety Data Sheets(MSDS) available from HaynesInternational, Inc.Inhalation of metal dust orfumes generated from welding,cutting, grinding, melting, ordross handling of these alloysmay cause adverse healtheffects such as reduced lungfunction, nasal and mucousmembrane irritation. Exposureto dust or fumes which may begenerated in working with thesealloys may also cause eyeirritation, skin rash and effectson other organ systems.The operation and maintenanceof welding and cutting equipmentshould conform to theprovision of American NationalStandard ANSI/AWS Z49.1,"Safety in Welding and Cutting".Attention is especially called toSection 4 (Protection of Personnel)and 5 (Health Protectionand Ventilation) of ANSI/AWSZ49.1. Mechanical ventilation isadvisable and, under certainconditions such as a veryconfined space, is necessaryduring welding or cuttingoperations, or both, to preventpossible exposure to hazardousfumes, gases, or dust that mayoccur.Acknowledgements:INCONEL is a registered trademark of Inco Family of Companies.RA330 is a registered trademarks of Rolled Alloys, Inc.253 MA is a registered trademark of Avesta Jernverks Aktiebolag.HAYNES ® 556 TM alloy 26
