As with any material, housekeeping is paramount to reducing potential employee exposures to any type of dust. During our Hazard Classification Study, we did find a relationship between extremely poor housekeeping conditions and the ability to detect respirable quartz. Although these exposures did not exceed the OSHA PEL, the levels were detectable by NIOSH Method 7500 when housekeeping was poor. As a reminder, with all dust, wet methods and/or vacuuming of dusts are the best ways to prevent the suspension of dust particles in the air.
