Exposure to crystalline silica can occur during common construction and demolition tasks when working with concrete, bricks, mortar, tiles, stone or other masonry. If employees regularly dry cut, grind, crush, drill, sweep or demolish these materials without engineering controls in place, it is likely that the exposure standard will be exceeded.
Figure 3.5 Preparation damage (arrows) in annealed CP titanium (500X, DIC, Kroll's reagent). A Planar grinding machine, like the PlanarMet 300 planar grinding machine shown in Figure 3.3, utilizes a fixed abrasive stone for rapid sample grinding. This type of automated grinder produces planar samples in 1-2 minutes replacing up to 3 traditional grinding steps.
