2015-11-25 In order for silica to be a hazard, silica-containing dust particles that are small enough to be inhaled (i.e., respirable) must get into the air. The strategy for controlling the silica hazard can therefore be broken down into three basic approaches: prevent silica dust from getting into the workplace air. remove silica dust present in the air.
