Do not roll over uncovered cables with any equipment.
Special precautions should be taken while walking over the cable
and while handling sharp tools during the installation process.
CAUTION!
Work stages should be planned so the cable does not remain
uncovered between the installation and the coating stages.
Where the project encounters any delay between these stages,
special precautions should be taken to mechanically protect
the cable against any breakage.
CAUTION!
