Crystalline Silica (Quartz) Dust Precautions
Follow OSHA or other guidelines for exposure to crystalline silica when trenching, sawing or drilling
through material that might produce dust containing crystalline silica (quartz).
Other Jobsite Precautions
You may need to use different methods to safely avoid other underground hazards. Talk with those
knowledgeable about hazards present at each site to determine which precautions should be taken or if
job should be attempted.
Breathing crystalline silica dust may cause lung disease. Cutting, drilling,
or working materials such as concrete, sand, or rock containing quartz may result in
exposure to silica dust. Use dust control methods or appropriate breathing protection
when exposed to silica dust.
