If you store the same chemical in different containers in the same location, you will
report each container type as a separate storage location.
For example: If you store the chemical in a Fiber and a Steel drum, you will report the chemical
once, but under the Storage Location section you will add a storage location for the chemical in a
Fiber drum container and one for the Steel drum container.
