<br />b) Microforms: <br /> <br />1) Silver Halide: <br /> <br />Send to or have picked up by professional microfilm processing laboratory. <br /> <br />c) Vesicular and diazo: <br /> <br />1) Wash with liquid detergent and rinse. <br /> <br />2) Layout on absorbent paper to dry. <br /> <br />Tapes and Floppy Diskettes <br /> <br />If the diskette itself has been damaged (by melting, creasing, etc.), restoration is very <br />difficult, and probably incomplete at best. If there is a loss of access to date due to foreign <br />material on the surface, this type of damage more readily allows restoration. To remove a <br />contaminant, follow these procedures: <br /> <br />a) Carefully remove diskette from jacket and sleeve. <br /> <br />b) Agitate the exposed diskette in multiple baths of cool, distilled water. <br /> <br />c) Dry with lint-free towels or air dry. <br /> <br />d) Insert diskette into new jacket. <br /> <br />e) Copy date to new diskette. <br /> <br />f) Clean copy equipment drive heads often to avoid permanent damage to heads. <br /> <br />other Magnetic Media <br /> <br />Have professionally cleaned and dried by an outside agency. <br /> <br />Section 9. RECOVERY PROCEDURES FOR OTHER TYPES OF DAMAGE <br /> <br />FIRE/SMOKE <br /> <br />PAPER <br /> <br />If records are not fragile, trim charred edges and clean the surface with a soft bristled <br />brush and rub gently with art gum eraser, mildly abrasive drawing paper, or wallpaper <br />cleaner. Typed material should first be tested to determine if correctable ribbon was <br />used; if so, do not use paper cleaner. <br />If records are too fragile, enclose in mylar folder and copy, using either paper or <br />microfilm. Discard the original, keeping a record of such action. <br /> <br />Smoke damaged records can be quick frozen to remove smoke smell. <br /> <br />Page 32 <br />
