Should I completely empty the silo or can I leave chemical in the silo for a long term shutdown?

Some bulk chemicals may degrade over time or absorb moisture from the air; some bulk chemicals may even solidify over time so it may be best to empty the storage silo in advance of a long term shut down. This will depend on your specific circumstances.

In addition, this may be an opportune time to inspect the silo’s internal structure and any instrumentation inside the silo.
