337 organizations worldwide were contacted, 64 responded.
Telephone interviews, written and web-based surveys. Responses were self-reported and not independently verified.
Respondents believe that there are special risks related to nanomaterials. However, their actual environmental health and safety practices did not significantly depart from standard hazardous material handling.
Few monitored the workplace for airborne nanoparticles or provided guidance to consumers regarding disposal.
Nearly half of organizations implementing nano-specific environmental health and safety programs described the practices as a precaution against unknown hazards.
