NAVFAC: GSA Approved Security Containers
Why GSA-Approved Security Containers Matter
When you are responsible for safeguarding sensitive information or high-value assets, the type of container you use is not just a purchasing decision—it is a compliance decision. GSA-approved security containers are built and tested to federal standards so they can be trusted to protect classified documents, critical components, arms, ammunition and explosives (AA&E), and other high-value materials.
These containers are a core part of the DoD Lock Program’s approved security hardware. Choosing the right class of container, keeping it in good condition, and understanding when it must be replaced are all essential responsibilities for facility managers, security officers, and contractors who work in high-security environments.
What Is a GSA-Approved Security Container?
A GSA-approved security container is a specially designed cabinet, safe, or similar unit that has been tested and certified to meet Federal specifications for protecting sensitive materials. According to NAVFAC, these containers are used for:
- Classified documents, components, materials, and media
- Small quantities of Risk Category II, III, and IV arms, ammunition and explosives (AA&E)
- Funds, valuables, weapons, and other high-value items
One important rule that NAVFAC emphasizes: classified and unclassified materials should not be stored together in the same container. Keeping these categories separate helps maintain clear accountability and reduces the risk of mishandling or compromise.
Label Colors and What They Tell You
Every GSA-approved container includes a label that identifies its approval status and class. That label is more than a sticker; it is proof that the container meets GSA standards. The label color also tells you when the container was manufactured and which set of requirements it was built to meet.
“Black Label” Containers
Containers manufactured before October 1990 typically have what many professionals refer to as a “black label”: a silver label with black lettering or a black label with silver lettering. These older units were compliant when installed, but the federal government has been phasing them out. They cannot be recertified or relabeled as current GSA-approved containers.
Red and Green Labels
After October 1990, GSA-approved Class 5 and Class 6 containers began using a silver label with red lettering. Historically, Class 7 containers were produced with a silver label and green lettering. While Class 7 units are no longer manufactured, you may still encounter them in older facilities.
During an inspection or service call, confirming the label color and condition is one of the fastest ways to determine whether a container is likely to still be acceptable for use or if it may require replacement under current guidance.
Understanding Container Classes: Class 5 vs. Class 6
The class rating on a GSA-approved security container is directly tied to how it is allowed to be used. NAVFAC outlines two primary classes currently manufactured:
Class 5 Containers
Class 5 containers are designed for high-security applications. They provide protection for classified materials and are also widely used for weapons, funds, jewels, precious metals, and other particularly valuable items. In addition to meeting the standards for classified storage, they offer an increased level of resistance to forced entry when compared with Class 6 units.
Class 6 Containers
Class 6 containers are primarily intended for the storage of classified information, such as documents, drawings, maps, plans, and similar materials. They are available in configurations like vertical file cabinets and map and plan files, making them practical for offices and secure records rooms where classified paper documents must be controlled.
NAVFAC provides detailed tables that list the container classes, Federal specifications, and performance requirements. Those tables are the technical reference used by government agencies, security officers, and vendors to ensure equipment meets
current standards.
Phase-Out and End-of-Service Dates
A crucial part of managing GSA-approved security containers is understanding their phase-out schedules. The federal government has established end-of-service dates for many older models, especially the black label units produced before October 1990.
In general, once a container reaches the end of its approved service life:
- It should no longer be used to store classified information or protected AA&E.
- It cannot be recertified or simply relabeled to extend its life.
- It should be replaced with a current-generation, red-label GSA-approved container.
If the GSA approval label is missing, damaged beyond recognition, or removed, the container is no longer considered GSA-approved.
That means it does not meet federal requirements for storing classified material, regardless of how it was originally built.
For facility managers and security personnel, this makes regular inspections essential. Any inventory that still relies on black label or unlabeled containers should be reviewed and scheduled for replacement.
Best Practices for Managing GSA-Approved Containers
Based on the DoD Lock Program guidance, here are practical best practices you can implement in your facility or recommend to your clients:
- Verify the GSA label. During inspections, always check that the GSA approval label is present, legible, and
matches the container class and manufacturer data. - Match the class to the contents. Confirm that the container’s class rating (Class 5 or Class 6)
is appropriate for what is actually being stored, whether it is documents, critical components, or weapons and valuables. - Keep classified and unclassified separate. Do not mix classified and non-classified materials in a single
container. This keeps accountability clear and aligns with federal guidance. - Monitor phase-out timelines. Track manufacture dates and any published end-of-service deadlines so you can
plan container replacements before a unit falls out of compliance. - Use compliant locks. When a lock fails or needs to be replaced, ensure that the new lock meets the current
Federal Specification (such as FF-L-2740 series) for high-security combination locks. - Document everything. Encourage the use of required forms and record-keeping, such as standard forms for
combination control and accountability, as outlined in Department of Defense manuals for classified information and AA&E.
