The emergence of metal 3D printing carries health risks associated with particle exposure, but a new study shows targeting critical tasks and preventative actions can protect workers.
Work health and safety regulations for diesel emissions are likely to be overhauled, after two research projects found occupational limits need to be slashed, and there are "critical gaps of knowledge" on the behaviour of nanoparticles.
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.
Australian researchers have identified increased levels of proteins associated with inflammatory responses in both workers who handle engineered nanoparticles (ENPs) and patients with cancer.
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.
