Quote of the day

Based on work performed to date with laboratory animals, NTRC believes that harmful pulmonary effects from exposure to specific nanotubes may constitute the major health risk for workers. NTRC has also preliminarily found that it is possible to control airborne exposure to nanoaerosols by using engineering controls such as exhaust ventilation and process enclosures. In addition, NTRC notes that preliminary evidence shows that respirators can be effective in protecting workers from particulates as small as 2.5 nanometers in diameter.
"While this evidence needs confirmation," says NIOSH, "it suggests that it is likely that NIOSH certified respirators will be useful for protecting workers from nanoparticle inhalation when properly selected and fit-tested as part of a complete respiratory protection program."
