Exposure to metal gases and particulates risks are documented with zinc, aluminum, and cobalt gases. There are some association with magnetite
nano particles and Alzheimer disorders. Thanks to EPG Blue Team for the reference The exposure to gas and small small particulates
is likely greater than exposure to the ferro-fluids due to the carrier fluid generally preventing release into the air.\
An exhaust fan or hood and normal protective gear should suffice for work with the ferrofluid core EPGS

that doesnt sound very healthy.... :)
Thanks for the warning, Jim.

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.
