This includes: ❑ Bed and Backfill ❑ Pre -Installation Testing ❑ Hole Size/Burial Depth ❑ Anchoring Tank Installation - Warnings and Cautions AWARNING • Do not enter the tank excavation unless necessary! Follow OSHA guidelines for tank excavations. • Collapsing excavation walls can cause injury or death!
