Dissemination Report n°6

​First results for safe procedures for handling nanoparticles.
Published on 5 October 2016

​Generally it is of common knowledge that risk assessment in using hazardous or potentionally hazardous chemical substances, either the exposition itself or the risk of those materials has to be minimised. The potential danger for someone can be derived from the basic fact, that direct contact with a potentially harmful substance has to be avoided.

Currently, it is still quite unclear, which nanoparticulated material in which state and from reveals which type of danger. It is also unclear, if current measurement and classification of conventional materials, such as critical mass concentration at working places can be applied for the industrial usage of nanoparticles at all.

Main results

  • Avoid free flowing nanoparticles in air Eliminate ignition sources. Extended personal protection equipments are required during (un)loading processes. EX-Zone should be defined.
  • Vacuum cleaning or variable speed fan with appropriate nanoparticle collection appear to be efficient cleaning method.
  • In terms of waste disposal labelling and packaging are carried out according to national and international regulations.

Final suggestions

  • Use of nanoparticles in dispersion or in an agglomerated state.
  • If this cannot be done, secure process containment is a must.
  • Inert processes, if applicable.
  • Efficient exhaust systems with particles filtration (e.g. HEPA filter H14).Personal protection equipment (Nitrile glove (2 pairs recommended), Mask (FFP3 or powered respirators incorporating helmets), Suits and safety shoes).
