What are the guidelines for indoor storage?

Seal tightly, mark and label all containers in storage. (Chemicals, flammables and trash are not allowed by most storage units. You are not allowed to live in the units.)
Secure storage facilities and limit access, as determined by the unit.
Exercise the First In First Out (FIFO) rule when issuing stored HM.
Store by characteristics and separate like items by a dike, berm or wall in main storage areas.
