AEROSIL® Fumed Silica - Handling & Logistics
Since AEROSIL® pyrogenic synthetic amorphous silica is a dusting powder material we recommend that exposure be maintained below the MAK-value by ventilation of the working area.
In the presence of high dust concentrations an approved respirator for nuisance dust should be worn.
Pyrogenic synthetic amorphous silicas are not explosiv or flammable.
Pyrogenic synthetic amorphous silicas (SiO2) do not burn. Therefore, for pure SiO2 there is practically no risk of dust explosion.
However, during handling silicas, even when emtpying bags, the phenomenon of electrostatic discharges might be observed. This is why we recommend precautionary measures against static discharges, like earthing and occasionally inerting the gas atmosphere of the recipient vessel. More detailed information about this issue is given in our Technical Bulletin No. 62 "Synthetic Silica and Electrostatic Charges".
To prevent the feeling of dryness of skin during contact, pyrogenic synthetic amorphous silica should be rinsed off with water and skin should be treated with cream.
Spilled material can be removed by sweeping or suction and placed into a suitable container without causing dust.
