10 Emergency Devices and Emergency Egress
(Reference 21CFR 1020.33 (f)(2)(ii))
10.1 Emergency Devices
The system has two types of Emergency buttons:
1. Emergency Stop — When pressed, all table and gantry motions are halted, generation of X-
rays is stopped, laser alignment lights are turned off. The system aborts any data acquisition
in progress, and attempts to save all data acquired prior to the abort. Use the Emergency
Stop button for patient related emergencies.
2. System Emergency Off Button — When pressed, the power to all system components is
removed, stopping all table and gantry motion and generation of X-rays. The system aborts
any acquisitions in progress, and data obtained prior to the abort can become corrupt or
lost. Use the System Emergency OFF button for catastrophic emergencies, such as fire or
earthquake.

Every operator should take a few minutes to locate the Emergency Stops on their
system before scanning the first patient.
The system has five Emergency Stop buttons:
