Nanotechnology  is  a  dynamic science producing  new  materials  and  products  with  extraordinary functional properties in of medicine, energy, aeronautics, and the environment. However, there  is     little  regulation  governing  this  science ,  specifically  with  regard  to  personal  and environmental exposure risks. 

Nanoparticles exhibit different and varying levels of toxicity, chemical, and physical properities in     comparison to their macroscale.  For these reasons alone the researchers must protect their breathing zones and implement  sound  risk  assessment  and  risk  management   strategy  by  investing  in    containment instrumentation.

Environmental Health and Safety

Organizations and Universities are now administering nano-specific EHS programs including training, and  monitoring  the  work  environment   which  translates  to  concerns  for  nano-researcher  safety. 

The specific safety protocols are contingent on nanomaterial life cycle stages, modifications, and disposal.    Containment  is  necessary   because   Nanotechnology   presents   vast   challenges   for  environmental monitoring and minimizing contaminants in the laboratory and workplace.

“A fundamental requirement for assessing the potential impacts of new nanomaterials on both human  health  and  environment  is  the  ability  to make precise, accurate measurements at  the nanoscale in multiple, complex media.”  (Strategy For Nanotechnology-Related Environmental, Health, and Safety Research; NNI pp12; Feb. 2008)

Understanding how analytical methods such as chemical or physical modifications affect the properties of nanomaterials is best     researched     inside    a     personnel protection equipment enclosure.  A low flow hood (60 - 75 lfpm) creates a  non turbulent  containment where risk is minimized, from both a personnel and sample perspective.
