Marking Labeling and Signage

* “Post signs indicating hazards, personal protective equipment requirements, and administrative control requirements at entry points into designated areas where dispersible, engineered nanoparticles are handled. A designated area may be an entire laboratory, an area of a laboratory or a containment device such as a laboratory hood or glove box.

  • Where appropriate, label storage containers to plainly indicate that the contents are in engineered nanoparticulate form, e.g., ‘nanoscale zinc oxide particles’ or other identifier instead of just ‘zinc oxide.’
  • When engineered nanoparticles are being moved outside a Center, also include label text that indicates that the particulates might be unusually reactive and vary in toxic potential, quantitatively and qualitatively, from normal size forms of the same material.“1
