Occupational exposure to welding gases during three welding processes and risk assessment by SQRCA method
Background: Hazardous chemical agents in the welding operation are a mixture of metal fumes and toxic gases, the inhalation of which causes adverse health effects among welders. The emission of gases in the workplace is a logical cause for concern regarding the potential development of respiratory disease. The aim of the present study was to determine the concentration values of gases discharge...
متن کاملExploring the risk of welders’ exposure to the gases and metal fumes in a shipbuilding industry: a case study
Introduction: Risk identification and investigation is an appropriate and practical approach for the occupational health professionals. This paper aims to determine exposure to the gases and metal fumes and to perform risk analysis in three common types of welding activities in a shipbuilding industry. Material and method: This analytical cross-sectional study was conducted in a shipbuilding i...
متن کاملChronic effects of welding exposure on pulmonary function tests and respiratory symptoms.
OBJECTIVES The respiratory effects of exposure to welding fumes have been investigated in numerous studies; but results of these studies have not been consistent. The aim of the present study was to investigate the respiratory effects of welding exposure in a large group of manual are welders exposed primarily to mild steel welding processes in confined spaces without respiratory protection. ...
متن کاملBronchial reactions to exposure to welding fumes.
OBJECTIVES To study the airway response and its mechanism to welding fumes in six welders with respiratory symptoms. METHODS Methacholine and welding challenge tests were carried out. The concentration of welding fumes during the exposure test was measured. On two subjects who developed bronchoconstricition to welding challenge, additional tests were carried out including prick, patch, and in...
متن کاملConcentration Evaluation and Health Risk Assessment of Welders' Exposure to Total Fumes and Manganese during Welding at Metal Industry
Introduction and purpose: Risk assessment of toxic or hazardous chemicals enables industrial hygienists to make appropriate decisions regarding management provisions in a healthy workplace. Exposure to total fumes and manganese during welding can have harmful effects on welders’ health. Therefore, the present study was conducted in the metal industry to evaluate the concentration and determine ...
