Most of the EPG teams are using laminar flow hoods with negative pressure, as well a gloves , eye covering and other protective gear when
working with the nano sized metal powders. Once they are mixed with aqueous or non aqueous carrier liquids as in ferrofluids the surface tension
reduces the the release of the small particles into the air, thus reducing risk.. Generally speaking it is best to avoid contact with mucous membranes
inhalation or contact with skin. The
vapors of aliphatic hydrocarbons such as the kerosene carrier liquids in some of the non aqueous ferro-fluids
are best avoided. Non sparking switches and a static spark reduction protocols should be used as a standard laboratory safety program.
