29 This document provides the shift checklist covering the Hall-C
30 base equipment. This checklist should be filled out at least
31 once per eight-hour shift during experiment data-taking shifts,
32 and at least once per 24-hour period during {\it Standby} shifts.
33
34 Each experiment should modify and/or amend this checklist to satisfy
35 its own particular needs.
36
37 The checklist itself composes Section 2. You should make multiple
38 copies of the pages of that section for shift workers to fill out.
39 The remaining sections provide guidance for filling out the checklist.
