Workers in construction and manufacturing jobs are often exposed to respirable crystalline silica, which is released when cutting or drilling into stone and concrete. Breathing silica dust is dangerous and can lead to serious and often fatal illnesses.
There are steps employers must take to protect workers by reducing exposure to dust. These steps include using controls like wet methods and ventilation. Respirators can be used, but only if other methods are not protective enough.
The following resources provide guidance for how employers can protect workers from hazardous exposures to silica dust.
