	It is important to note that PPE such as a face mask is only the last resort in order to keep you safe. It is much more important to prevent wires from escaping by good laboratory practice and working under the fume hood than it is to behave irresponsibly and wear a facemask. Also remember that the dimensions of the particles are small in one direction, so your mask should ensure that dimension cannot get through. This means that only class P3 particulate filter masks will suffice!		It is important to note that PPE such as a face mask is only the last resort in order to keep you safe.

	The possible implications of inhaling nanowires (carbon, silicon, indium arsenide, etc) are not yet fully investigated nor understood. It is thus sensible to assume that there might be a potential health risk associated with the inhalation of nanowires. The reason for this assumption is that the dimensions of nanowires and asbestos are similar. This means that the risk is associated to the ratio of the length ''l'' of the wire divided by its diameter ''d'' being larger than 3 and smaller than 10. The dimensions that might potentially cause the highest health risk are ~~(l = length, d = diameter)~~:		The possible implications of inhaling nanowires (carbon, silicon, indium arsenide, etc) are not yet fully investigated nor understood.
