The growing evidence from animal studies that nanomaterials can be harmful to health should compel employers to eliminate or reduce exposure to the tiny particles through the hierarchy of controls - immediately, according to special guidance from the American College of Occupational and Environmental Medicine.
OHS risks arising from the increasing use of 3D printing across multiple industries include exposure to hazardous substances, the proliferation of non-conforming building products and poor worker wellbeing, according to a special report from Europe's peak safety agency.
Chemicals that are hazardous to employees' reproductive health are common in workplaces, but a lack of awareness on individual and organisational levels means people continue to be exposed to them, an occupational health researcher says.
A study of tunnel construction work has identified the types of workers exposed to high concentrations of hazardous ultrafine particles, which are associated with respiratory and cardiovascular disease.
A new Safe Work Australia report has confirmed that certain nanomaterials could cause mesothelioma, while Europe's peak safety agency has outlined steps employers can take to reduce the risk of workers developing cancer.
Two new studies on nanotechnology have outlined how to control emissions resulting from the machining of composites - that do or don't contain nanomaterials - and avoid explosions involving metal nanopowders, which have caused workplace deaths.
