Security of Copper

Keep larger amounts of copper in a securely fenced yard or building when not in use

Copper cable should be brought to the work site in sufficient quantities for that day’s work

Decommissioned copper cable removed from buildings must be secured in a bin

Work Planner is responsible to secure copper at end of the working day
