Abstract

Due to uncertainties, it is difficult to directly apply conventional risk management methods designed for bulk chemicals to workplaces involving nanomaterials without modification and adaptation. Based on this, Omari Shekaftik et al., in an article titled “An analysis of “hierarchy of controls” in workplaces and laboratories involving nanomaterials” published in the Journal of Nanoparticle Research, sought to examine the applicability of the NIOSH-recommended hierarchy of controls in workplaces involving nanomaterials. A short report has recently been published by Berger et al. in Journal of Nanoparticle Research, in which they critique our article and point out several issues. Therefore, in this brief report, we aim to further clarify our work and address the concerns raised by the authors of that report as well as those of the readers. © The Author(s), under exclusive licence to Springer Nature B.V. 2026.
