This standard provides guidance on occupational health and safety measures related to engineered nanomaterials, including the use of engineering controls and appropriate personal protective equipment, guidance on handling accidental spills and releases, and guidance on handling. of these materials during their final disposal. This standard is intended for use by competent personnel, such as health and safety managers, production managers, environmental managers, industrial or occupational hygienists and others responsible for the safe operation of facilities dedicated to the production, handling, transformation and final disposal of engineering nanomaterials. This standard is applicable to engineering materials consisting of nano-objects such as nanoparticles, nanofibers, nanotubes and nanowires, as well as aggregates and agglomerates of these materials (NOAA). The term "NOAA", as used in this standard, applies to these types of components either in their original form or incorporated into materials or preparations from which they could be released to some extent during their life cycle, including, as a result, subsequent activities such as final disposal.
