Claim 0:
1. A coiled tubing system, comprising:
an injector assembly configured to receive and longitudinally move coiled tubing through the injector assembly;
a well control stack operatively coupled to the injector assembly and configured to receive the coiled tubing from the injector assembly; and
a snap arrestor including:
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,

wherein, when the real-time measured linear speed of the coiled tubing exceeds a predetermined linear speed threshold, a command signal is sent to the injector assembly to grippingly engage the coiled tubing and thereby arrest longitudinal movement of the coiled tubing.
