With regards to best business practices, most GSA Security containers should have an "OPEN/CLOSED" sign. This may be either a magnetic sign or one that fits into the handle of the top drawer. The purpose of these signs is to be able to determine from a distance whether the container is opened or closed. This helps to mitigate risk and ensure security of stored documents and/or materials.
"Open" on one side
