Start from the collection plan that says where nitrate film is stored and handled, then check that the vault or cabinet construction, venting, sprinklers, and room separation on each discipline’s drawings describe the same rooms. AI can flag conflicts; the design team, the collection owner, and the authority having jurisdiction decide compliance.
What does NFPA 40 cover?
NFPA 40 is the Standard for the Storage and Handling of Cellulose Nitrate Film. NFPA’s page states that it provides guidance on safe storage and handling of still and motion picture cellulose nitrate-based film located in film cabinets, vaults, archival vaults, projection booths, laboratories, and film exchanges.
NFPA’s official NFPA 40 page identifies the 2025 edition as current when checked on October 10, 2026. Confirm the edition, local amendments, and project scope that actually govern the work. The publisher’s newest edition does not establish local adoption.
Nitrate film collections usually sit inside buildings covered by the NFPA 909 cultural resources guide, and general records rooms by the NFPA 232 records guide. Record which rooms will hold nitrate film and in what form before comparing.
Gather the collection plan and the vault drawings
Collect the collection or storage plan, the floor plans and enlarged plans of vaults and handling rooms, the wall, floor, and roof construction, the vent and exhaust drawings, the sprinkler drawings, the door schedule, the mechanical drawings for temperature and humidity control, the fire alarm drawings, and the specifications.
Vault venting usually crosses the architectural and mechanical sheets. Upload both so each vent route can be compared from the vault to the outside.
Follow each vault through the disciplines
| Review question | Sources to compare | Decision to record |
|---|---|---|
| Storage locations | Collection plan, floor plans, room names | Confirm each nitrate vault, cabinet room, or handling room is named the same in every source. |
| Vault construction | Wall types, sections, enlarged plans | Check that the construction around each vault agrees between the plans, sections, and wall types. |
| Venting | Vent drawings, mechanical plans, roof and wall sections | Trace each vault vent to the outside and find routes that differ between sheets. |
| Sprinklers | Sprinkler drawings, enlarged plans, specifications | Match the sprinklers drawn in each vault with the vault layout and specifications. |
| Doors and separation | Door schedule, rated wall plans, hardware | Ask the designer to confirm the doors and walls separating vaults from other rooms and that sources agree. |
| Environmental controls | Mechanical drawings, collection plan, specifications | Identify ducts or equipment serving a vault that the vent and separation details do not address. |
Detection in collection areas follows the NFPA 72 guide. These questions come up in museum and cultural and library projects; the fire sprinkler checklist tracks the sprinkler questions.
Example: a vault vent that ends at a different wall
Hypothetical example. An archive adds a nitrate film vault to an existing storage wing. The enlarged architectural plan shows the vault vent leaving through the north exterior wall, while the mechanical drawings route it up to the roof and the sprinkler drawings show the vault before shelving was added.
The enlarged plan shows the vault vent leaving through the north wall, but the mechanical drawings route it to the roof, and the sprinkler drawings show the vault before shelving was added. Please confirm the vent route and coordinate the sprinkler layout with the shelving.
The design team confirms the vent route and the sprinkler layout is updated. Compliance is decided by the designers and the authority having jurisdiction.
Review a nitrate film vault with Groundbook
Upload the current project PDFs and relevant specifications to Groundbook. Identify the governing issues and add the applicable NFPA 40 reference from a copy you are licensed to use, where the license permits uploading it. State the edition, amendments, review area, and known exclusions in your instructions.
Compare the collection plan, floor and enlarged plans, construction drawings, vent drawings, sprinkler drawings, door schedule, mechanical drawings, fire alarm drawings, and specifications. Flag storage locations, construction, vents, sprinklers, doors, and environmental controls that differ between sources. Use the supplied NFPA 40 edition where applicable and cite both sources.
Groundbook links each potential finding to the sheets involved and the reference you uploaded.
Document review does not assess film condition, size vents, or approve the vault. Those decisions remain with the design team, the collection owner, and the authority having jurisdiction.
