Abstract
A protection tool is provided to protect a control line in a safe area while one or more slips of a spider are being closed. In another embodiment, a safety interlock system is provided to prevent the closing of the slips before the control line is pulled away from the tubular string. In yet another embodiment, a safety interlock system includes a safety interlock trigger adapted to be actuated by a protection tool. The safety interlock trigger is adapted to detect the physical presence of the protection tool, and thereafter send a signal to the interlock system to enable an operator or a control mechanism to safely close the slips.
