Aluminum 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 کاملSponsored by the American Welding Society and the Welding Research Council Chemical Analysis of Welding Fume Particles
Welding fume contains elements that, in their pure forms, can be hazardous to worker health if inhaled or ingested. Therefore, the chemical composition of welding fume must be examined when considering fume toxicity. Various chemical analysis techniques are presented and their applicability to airborne particles is described. Knowledge of particle size is important because a given characterizat...
متن کاملEffect of welding fume on heart rate variability among workers with respirators in a shipyard
Welding fume exposure is associated with heart rate variability (HRV) reduction. It is still unknown whether respirator can reduce effect of welding fume on HRV among welding workers in a shipyard. We recruited 68 welding workers with respirator and 52 welding workers without respirator to measure HRV indices, including standard deviation of normal-to-normal intervals (SDNN) and square root of ...
