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.
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.
