Claim 9:
10. A method, comprising:
receiving coiled tubing at an injector assembly having a well control stack operatively coupled thereto;
operating the injector assembly to longitudinally move the coiled tubing through the injector assembly and the well control stack;
calculating a real-time measured linear speed of the coiled tubing with a snap arrestor that includes:
one or more wheels configured to rotate as the coiled tubing moves longitudinally;
a tachometer that measures rotations per minute (RPM) of the one or more wheels; and
a microprocessor that receives and converts the RPM into a real-time measured linear speed of the coiled tubing;

sending a command signal to the injector assembly when the real-time measured linear speed of the coiled tubing exceeds a predetermined linear speed threshold; and
in response to receipt of the command signal, grippingly engaging the coiled tubing with the injector assembly and thereby ceasing longitudinal movement of the coiled tubing.
