Despite recent concerns for workers’ health, exposure situations to nanoparticles can occur in numerous workplaces. Understanding how exposures occur considering human work in these transformations remains a crucial issue of nanotechnologies. The objective of this article is to understand exposure situations to nanoparticles, their determinants and the resources to act on them.

This understanding was achieved by specific measurement of nanoparticles aerosols, combined with an analysis of work activity (actions performed and physical strain) in a rubber industry. The presentation of real time measurements, associated with the video of work situations, during confrontation interviews becomes a means of making exposing work activities visible, to analyze and transform them from the points of view formulated by the company's stakeholders. In this way, characterized “typical exposure situations” serve to trigger discussions and open up new spaces for debate highlighting how innovation affects work and gives rise to enhanced prevention projects.

尽管最近担心工人的健康，但在许多工作场所中仍可能发生纳米颗粒的暴露情况。考虑到人类在这些转变中的工作，了解暴露如何发生仍然是纳米技术的关键问题。本文的目的是了解纳米粒子的暴露情况，其决定因素以及对其采取行动的资源。

通过对纳米颗粒气溶胶的特定测量，并结合橡胶行业的工作活动（进行的作用和物理应变）的分析，可以实现这种理解。在面对面访谈期间，与工作情况的视频相关联的实时度量的呈现成为使暴露工作活动可见，从公司利益相关者提出的观点进行分析和转换的一种手段。这样，具有特征性的“典型暴露情况”有助于引发讨论并开辟新的辩论空间，突出强调创新如何影响工作并引发加强的预防项目。
