Controlling the risk of dust exposure to workers in

The risk of workers being exposed to hazardous dust particles should be controlled using the hierarchy of controls shown below. Controls should focus on higher-order controls (e.g. elimination, substitution and isolation of the hazard) as the most effective means of treating the hazard.

Preparation of Silica-Alumina Nanoparticles via Blast

Blast-furnace slag (BFS) has been used as a feedstock for CO2 sequestration by indirect mineral carbonation to produce calcium carbonate precipitates and solid residues. The most-abundant elements in these residues, Si and Al, are usually considered to be impurities that need to be removed in acid-dissolution processes involving BFS. The co-production of value-added materials from these
