# How to prepare instruments for Natural Disasters If an instrument is located in an area that is expected to be affected by a natural disaster (hurricane, tornadoes, storms, etc), see the following instructions to prepare them: 1. Perform washes as instructed in the [Instrument maintenance and shutdown procedures for extended site closures](https://illumina.lightning.force.com/lightning/r/Knowledge__kav/ka0aJ000000HpKfQAK/view) 2. Power off the instrument via normal processes in the instrument system guide. 3. Unplug the instrument from the power source (remove the power cord). Upon return to work: 1. Plug the power cord back and turn the instrument on. 2. Perform two maintenance/manual washes to rehydrate the fluidics system. 3. Perform a system check following the instrument system guide. If system checks fail or any other errors are observed, contact [Illumina Technical Support](https://www.illumina.com/company/contact-us.html#/united-states/technical-support). \ \ \
