Exposure to Inhalable, Respirable, and Ultrafine Particles in Welding Fume
This investigation aims to explore determinants of exposure to particle size-specific welding fume. Area sampling of ultrafine particles (UFP) was performed at 33 worksites in parallel with the collection of respirable particles. Personal sampling of respirable and inhalable particles was carried out in the breathing zone of 241 welders. Median mass concentrations were 2.48 mg m(-3) for inhalab...
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 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 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 کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
