Which is an effective engineering control to reduce silica exposure when cutting concrete?
a.Working faster
b.Using water (wet methods) or local exhaust ventilation to suppress dust
c.Holding your breath
d.Cutting in an enclosed room with no ventilation
Explanation
Wet cutting methods and tools with local exhaust ventilation and vacuum dust collection are effective engineering controls that keep silica dust out of the air. These controls are preferred over relying on respirators alone. Reducing dust at the source protects everyone nearby.
