Cutting concrete, brick, or stone can release respirable crystalline silica. What is the primary control OSHA's silica standard emphasizes for construction tasks?
a.Blowing dust away with compressed air
b.Ignoring dust below waist height
c.Engineering controls such as water (wet cutting) or vacuum dust collection to limit exposure
d.Only wearing gloves
解析
1926.1153 emphasizes engineering controls — water suppression and vacuum dust collection — often via Table 1 specified controls, to keep respirable silica below the permissible exposure limit. Dry cutting without controls is a serious hazard.
