At least 46,000 Australian welders are exposed to high levels of dangerous, potentially cancer-causing fumes at work and there are not enough workplace safety measures to protect them, new research co-published by the University of Sydney has found.

The research team from Curtin School of Population Health and the University of Sydney surveyed

634 workers and employers involved in welding in Australia, and asked participants about work tasks, their working environment, and safety measures implemented in their workplace.聽

The survey revealed the majority (91 percent) of welders are exposed to 鈥榳elding fume鈥�, a mixture of very fine particles and gases produced when a metal is heated above its boiling point.聽 Welding fume is a known carcinogen in humans.

The Australian-first study was published today in the Australian and New Zealand Journal of Public Health and funded through the NSW government鈥檚 Centre for Work Health and Safety.聽

聽The researchers say that exposure聽 meant it was highly likely other carcinogenic metals were also often present. Most commonly, more than three-quarters of working environments involving welding are exposed to hexavalent chromium, a common contaminant that arises during welding, while almost half are exposed to stainless steel and nickel.

高清福利片 co-author Professor Tim Driscoll from the University of Sydney said the exposure risk was exacerbated by the conditions in which most welders worked. Two-thirds of respondents said they welded in restricted spaces and, more concerningly, nearly half said they worked in confined spaces.聽Most (86.3 percent) also reported leaning over the welding area while working, often putting their breathing zone directly above the fume source.

鈥淒espite this, only 19 percent of study participants said their workplace had some form of mechanical ventilation, such as a welding booth or exhaust hoods,鈥� said Professor Driscoll.

鈥淕iven that many Australian workplaces are apparently without effective ventilation, it is even more concerning that nearly two-thirds of workers in non-ventilated areas reported they do not use an air-supplied welding helmet.鈥澛牳咔甯＠�片 lead 聽 from Curtin University who was previously involved in a landmark study outlining the dangers of working with , said this new research showed many welders in Australia could be at risk of developing serious health problems.聽

鈥淒ata shows at least 60,000 people are employed as welders, however the number of people who complete welding tasks as part of their job would be far higher,鈥� Dr Carey said.

鈥淲elding fume exposure has been associated with various adverse health effects, including cancer, respiratory disease, neurological disorders and reproductive effects.鈥�

Public Health Association Chief Executive Terry Slevin said the study revealed serious health risks which must be reduced.

鈥淲e have seen strong action to reduce the health problems linked to asbestos and silica; this is another example where Australia鈥檚 health and safety legislation must be put to work to protect our tens of thousands of welders,鈥� Adjunct Professor Slevin said.

鈥淭his study demands every professional welder in Australia be supplied with upgraded protective equipment to make their work as safe as humanly possible.

鈥淲e have the technology _ now we need to ensure it is mandatory to use it in our workplaces.鈥�

An upcoming study will examine more precise levels of exposure to welding fume and the use of control measures in workplaces. This will be the subject of a forthcoming report.
