| Once your microfilm is developed the most important factors that will affect its
availability for future generations are storage conditions. |
 |

| Heritage Archives' vault meets the highest ANSI/AIIM Standards: |
- Temperature: We maintain our vault at a constant year around temperature of 60 degrees Fahrenheit.
- Humidity: Our vault is dehumidified to maintain a constant 50% or lower relative humidity.
- Fire-protection: Our vault is specially constructed with two-hour fire burn through protected walls and ceilings
and a concrete floor. The vault has a steel fire door with vapor seals for exceptional burn through protection. An
internal sprinkler system protects your film and our entire building has a fire detection and burglar alarm system.
- Flat Storage: According to ANSI specs all microfilm canisters are to be stored lying flat. If the canisters are
stored on edge (as many do) the gelatin coating that contains your images will migrate from spindle pressure - eventually
blurring the images.
Heritage only stores canisters flat.
- Periodic Evaluation: Every other year we examine every canister for signs of destructive redox or vinegar syndrome.
This inspection provides assurance that no degradation is affecting your film.
- Molecular Sieves: Air borne contaminants are a primary cause of premature degradation. In every canister we place 3 packets to scavenge moisture, acetic acid, and other
harmful contaminants from the microenvironment surrounding your film. No other newspaper archivists go to this length to ensure the safety and long-term health of the microfilm entrusted to them.
