Abstract
Nanoparticles, according to the ASTM standard E2456, are a subclassification of ultrafine particles having two or three dimensions ranging from 1 to 100 nm [1]. Engineered nanomaterials can be defined as an engineered structure having at least one external dimension between 1 and 100 nm. Nanomaterials incorporate nanoparticles and are being used in many different industries for products that include electronics, sporting goods, medicine, clothing, and many more [26]. The research and development of nanomaterials has surpassed knowledge of their health and environmental effects. This has resulted in a need for additional safe handling guidelines, regulations, and risk assessment procedures for workers in research laboratories and manufacturing facilities that work with and are exposed to nanomaterials [8]. The purpose of this article is to provide information and guidelines for workers who use nanomaterials in an occupational setting in the hope of, if suggestions are followed, improving worker safety, producing safer products, and providing insight into the steps being taken to minimize risks and impose regulatory standards.
