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

Jobsite hazards could cause death or serious injury. Use correct
equipment and work methods. Use and maintain proper safety equipment.
NOTICE: Cutting, drilling or working materials such as, concrete, sand or rock containing quartz may
