This literature review, with 232 citations, was prepared under contract to the American Welding Society for its Safety and Health Committee. The review deals with studies of the fumes, gases radiation, and noise generated during various arc welding processes. Section 1 summarizes recent studies of occupational exposures, Section 2 contains information related to the human health effects, and Se...
BACKGROUND Welding can produce dangerous fumes containing various metals especially carcinogenic ones. Occupational exposure to welding fumes is associated with lung cancer. Therefore, welders in Gas Transmission Pipelines are known as a high-risk group. This study was designed to determinate the amounts of metals Cr, Ni, and Cd in breathing zone and urine of welders and to assess the possibili...
BACKGROUND The current prospective study investigated the hypothesis of metal fume fever (MFF) being a predictor for the development of respiratory symptoms and functional abnormalities. METHODS The study consisted of a pre-exposure and two follow up assessments of 286 welding apprentices during an average period of 15 months. A respiratory and a systemic symptom questionnaire, skin prick tes...
C onfined spaces exist in nearly every industry, and many workers come into contact with at least one during the course of their work. According to the Occupational Safety and Health Administration, about 90 deaths involving confined spaces occur every year across a wide range of industries. Unfortunately, two-thirds of those deaths are workers killed while trying to rescue someone else from a ...
Under HSE’s wide-ranging initiative to bring about a reduction in occupational disease arising from exposure to dusts, gases, vapours and fumes, welders have been identified as an ‘at risk’ group. The initial stage in this process is to identify and set out the underlying evidence base for the potential ill-health effects arising from inhalation exposure. Hence, the purpose of this paper is to ...
Metals in particulate matter (PM) are considered a driving factor for many pathologies. Despite the hazards associated with particulate metals, personal exposures for at-risk workers are rarely assessed due to the cost and effort associated with monitoring. As a result, routine exposure assessments are performed for only a small fraction of the exposed workforce. The objective of this research ...
background welding is defined as linking two metals with a local conjunction in sufficient thermal, pressing and metallurgical condition. there are several methods for linking two metals in welding. objectives welding is one of the professional jobs in iran, yet there have not been considerable studies on its harmful effects. the current study aimed to compare lung functional tests between weld...
