Engineered Nanomaterials (ENM), also known as engineered nanoparticles, are defined as materials that have been intentionally created and have structures with at least one dimension between 1 and 100 nanometers (nm). ENMs are unique materials that require specific controls and procedures due to the unknown toxicity of many of the materials. Of particular concern is the use of ENM that are “unbound” and could more easily become airborne and present a greater hazard through inhalation (or ingestion).
Training: Employees who either use, handle, or who may be exposed to the hazards of ENMs are required to take the following safety courses: EHS 348 Chemical Hygiene and Safety and EHS 344 Safe Handling of Engineered Nanoscale Particulate Matter. Craft and Technical Workers, not directly working with ENM, but who may have potential contact through their work, must complete EHS 0356 Nano Safety for Crafts and Technical Work.
