• Acute exposure to welding fume and gases can result in eye, nose and throat irritation, dizziness and nausea. Workers in the area who experience these symptoms should leave the area immediately, seek fresh air and obtain medical attention.
• Prolonged exposure to welding fume may cause lung damage and various types of cancer, including lung, larynx and urinary tract.
