In the absence of scientific clarity regarding the potential health effects of occupational exposure to nanoparticles, there is a need for guidance in making decisions about hazards, risks, and controls (Schulte & Salmanca-Buentello, 2007). Presently, no guiding principles have been universally accepted for personal protective equipment that is worn to prevent exposure to nanomaterials. The purpose of this article is to survey the literature and determine if research has been completed that validates whether or not occupational exposure to nanomaterials is potentially hazardous to the health of humans.
