Code of Massachusetts Regulations › 950 CMR - OFFICE OF THE SECRETARY OF THE COMMONWEALTH › Title 950 CMR 39.00 - Regulations On Using Microfilm › Section 39.06 - Storage

Current through Register 1525, July 5, 2024
Standards for storing original or duplicate film shall comply
				with
Processed Safety Photographic Film - Storage
, ANSI IT
				9.11. In regard to the original film, the following storage standards shall be
				met:
(1)
Film
			 Enclosures.
Film enclosures shall be chemically stable and shall
			 meet the requirements of ANSI IT 9.2.
Materials used for film enclosures shall be free of acids and
				peroxides that may be released over time and cause degradation of the film.
				Paper and paperboard materials shall meet the requirements of the photographic
				activity test as outlined in ANSI IT 9.2.
Only enclosures of inert plastic or non-corrodingmetal such as
				anodized aluminum or stainless steel shall be used. Steel will be permitted
				only if such reels are well-protected by lacquer, enamel, tinning, or other
				corrosion-resistant finish.
Enclosure materials shall be sufficiently fire-resistive that
				they will not ignite or emit reactive fumes after heating for four hours at
				150°F. Melting and distortion of the enclosure materials after such heating
				shall not damage or prevent the film from being removed from the
				enclosure.
Plastics and lacquers that might give off reactive fumes or
				emissions during storage shall not be used. Suitable plastic enclosure
				materials are photographic film support material such as uncoated polyester or
				cellulose acetate. Highly plasticized sheetings or coatings shall not be used.
				The plastics must be free of peroxides.
The use of rubber bands, tape, paper strips, etc. for fastening
				film onto reels or cores is prohibited. The materials used shall not ignite,
				decompose, or develop reactive fumes or vapors. Filmonreels may be confined by
				tucking the film end between the roll and the flange.
All adhesives shall meet the standards of ANSI IT 9.2.
(2)
Storage
			 Containers
. The film shall be packaged either in chemically stable
			 containers of metal or inert plastic of proven quality or paper-board boxes of
			 low acidic composition. Plastics and lacquers that might give off reactive
			 fumes or emissions during storage shall not be used. The plastics must be free
			 of peroxides. All containers and adhesives shall meet the standards of ANSI IT
			 9.2. Containers shall be sealed when necessary to maintain prescribed humidity
			 limits or to protect the film against gaseous impurities. If proper temperature
			 and humidity are maintained as prescribed in 950 CMR 39.06(4), and if there is
			 good ventilation and cleanair in the storage area, the containers need not be
			 sealed. Each container shall be properly labeled with the series title, reel
			 numbers, and number of documents (where possible). All inks used for labeling
			 shall pass the photographic activity test outlined in ANSI IT 9.2.
(3)
Storage
			 Housings
. Micro film shall be stored in closed housings such as
			 drawers or shelving units equipped with doors, unless the film is in closed
			 containers, in which case open racks and shelves may be used. Storage housings
			 shall be noncorrosive and noncombustible. Air conditioning or ventilation shall
			 be provided in accordance with ANSI IT 9.11.
(4)
Storage
			 Facilities
. All original film shall be housed in clean, dust-free,
			 environmentally controlled circumstances affording the maximum in security. All
			 storage areas shall be constructed and maintained in accordance with
Processed Safety Photographic Film - Storage
, ANSI IT9.11.
Heat and humidity can deform the film base and weaken the
				emulsion. Since the emulsion is an organic product, mold growth can also occur.
				The average relative humidity in areas in which first generation, master film
				is stored shall be between 20% and 30% with daily fluctuations not to exceed
				5%. Temperature shall not exceed 70°F. with lower temperatures providing
				better keeping characteristics.
Storage areas shall be equipped with air filters since
				air-entrained impurities, in the form of particulates, can cause abrasion of
				the film and certain fumes may react with the film to degrade the image
				.
First generation, master film shall be stored in fire resistant
				safes or vaults. Safes shall be UL Class 150 rated four hours. Vaults shall
				provide protection equivalent to ANSI/NFPA 232 except that provision for
				air-conditioning shall be made in accordance with ANSI IT9.11. Except in fire
				resistant buildings, all safes shall be on ground-supported
				flooring.
