The composition of the base metals, the welding materials used, and the welding processes affect the specific compounds and concentrations found in the welding fume. • NIOSH Criteria Documents 76–129 and 77–164 (listed below) contain these conclusions based on data from the chromate producing industry and from nickel ore-refining processes. • Conclusions from the International Agency for Research on Cancer (IARC): (1) there is limited evidence in humans for the carcinogenicity of welding fumes and gases, and (2) there is inadequate evidence in experimental animals for the carcinogenicity of welding fumes. IMMEDIATE EFFECTS OF OVEREXPOSURE TO FUMES CONTAINING CHROMIUM AND NICKEL • Similar to the effects produced by fumes from other metals. • Cause symptoms such as nausea, headaches, dizziness, and respiratory irritation. • Some persons may develop a sensitivity to chromium or nickel which can result in dermatitis or skin rash. CHRONIC (LONG TERM) EFFECTS OF EXPOSURE TO FUMES CONTAINING CHROMIUM AND NICKEL • Definite effects
