Factors Affecting the Capture Efficiency of a Fume Extraction Torch for Gas Metal Arc Welding
Welding fumes are classified as Group 2B 'possibly carcinogenic' and this prompts to the implementation of local exhaust ventilation (LEV). The fume extraction torch with LEV integrated into the tool is the most attractive solution but its capture efficiency is often disappointing in practice. This study assesses the main parameters affecting fume capture efficiency namely the extraction flow r...
متن کاملAluminum welding fume-induced pneumoconiosis.
Chronic exposure to high concentrations of fumes during aluminum arc welding causes a severe pneumoconiosis characterized by diffuse pulmonary accumulation of aluminum metal and a corresponding reduction in lung function. Aluminum fume-induced pneumoconiosis is a rarely reported entity, of which the true incidence is unknown. We report the clinical, radiographic, microscopic, and microanalytic ...
متن کاملWelding Fume and Gas Exposure
A recent $1 million award by an Illinois jury to a welder was the first plaintiff victory in a welding rod failure-to-warn suit and many similar cases are expected to follow. In the case of Elam v. AO Smith et. al., the jury concluded that the manganese in welding fumes caused a 65-year old worker to develop a neurological disorder similar to Parkinson’s disease (i.e., Manganism). Since there a...
متن کاملReduction of Biomechanical and Welding Fume Exposures in Stud Welding.
The welding of shear stud connectors to structural steel in construction requires a prolonged stooped posture that exposes ironworkers to biomechanical and welding fume hazards. In this study, biomechanical and welding fume exposures during stud welding using conventional methods were compared to exposures associated with use of a prototype system that allowed participants to weld from an uprig...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
