Common scenarios where people may be exposed include:-breaking, crushing, grinding or milling silica-containing material such as concrete, aggregate or mortar-drilling, cutting, chiselling or sanding silica-containing material-dealing with cement-moving earth, eg excavating, mining, quarrying
Silica Gel: Properties, Uses and Side Effects
Silica gel is basically a highly porous, non crystalline, slightly transparent form of silicon dioxide commonly known as silica. Silica gels are majorly used to remove moisture from solid and gases, for liquid thickening, for polishing a surface to paint and glass making. The silica gel chemical formula is mSiO2.nH2O. Silica gel structure is-.

Alkali-silica reaction in concrete - Understanding Cement
Over time, the gel slowly does take up calcium; eventually the composition of the alkali-silica gel may become very similar to that of the calcium silicate hydrate in the cement paste (see Figure 4). By then, though, the damage to the concrete may have already been done.

Small-scale processing of microbial pesticides. Chapter 4.
The virulence of the fluidized bed-dried material is enhanced and the process accelerated by precipitation using a calcium carbonate, surfactant, silica gel mixture. In addition, a sulphite liquor is mixed in. Drying in a vacuum desiccator produced samples of high viability and virulence, some remaining active for 1 year at 4 o C storage.

Silica Dust Exposure Limits, Regulations And The Law - HASpod
Silica dust has a workplace exposure limit (WEL) of 0.1 mg/m3, expressed as an 8-hour time-weighted average (TWA). Exposure should be reduced as low a reasonably practicable, and at least below the WEL. Because the WEL for RCS is an 8-hour WEL, you can exceed it but only for a short amount of time.

Moreover, the milling tools should be cleaned and kept inside vacuum-silica gel dissectors in order to protect them from any expected contamination by the dust. Such storing conditions offer prefect protection against corrosion for the steel-based milling tools.-The type of the ball mill used should be considered as an important factor.
