This CEN Technical Specification describes a systematic approach to assess potential occupational risks to nano-objects, and their agglomerates and aggregates (NOAA) arising from the production and use of nanomaterials and/or nano-enabled products. This approach provides guidance to identify exposure routes, exposed body parts and potential consequences of exposure with respect to skin uptake, local effects and inadvertent ingestion. This Technical Specification also considers occupational use of nano-enabled personal care products, cosmetics and pharmaceuticals, but excludes deliberate or prescribed exposure to these products. This Technical Specification is aimed at occupational hygienists, health and safety professionals, and researchers to assist recognization of potential risks, and their control.
