-====== ​Emergency ​Shutdown ======+====== Shutdown ​S800/S3 Vault ======
 The following checklist describes the steps to follow during an emergency shutdown. The assumed scenario is that where the entire S800 (and S3 vault) must be turned off due to multiple reasons. Please, be aware that the procedures described below involve many different systems in the lab. As such, it is highly recommended to coordinate with operations staff using all available communication channels (face-to-face,​ hourlog, 8am-meeting and short-meeting). Also, as long as it is possible (the nature of an emergency shutdown may require to act very quickly), a Work-Control-Plan should be submitted. ​ The following checklist describes the steps to follow during an emergency shutdown.
