[Libs-Or] REALM Project Test 4 Results Available

[Arlene Weible]

The REALM project has published the results of the fourth round of Battelle's laboratory testing for COVID-19 on five materials. Four of the five items-hardcover book cover, softcover book cover, plastic protective cover, and DVD case-were part of Test 1, but in this round, the materials were stacked to simulate storage in a book drop, bin, or on shelves. The fifth item, expanded polyethylene foam, is commonly used in museum exhibits, storage, and shipping and was tested unstacked in open air.

Results show that after six days of quarantine the SARS-CoV-2 virus was still detected on all five materials tested. When compared to Test 1, which resulted in nondetectable virus after three days on an unstacked hardcover book, softcover book, plastic protective cover, and DVD case, the results of Test 4 highlight the effect of stacking and its ability to prolong the survivability of the SARS-CoV-2 virus.

Based on the materials' porous cellulose composition, liquid disinfection methods may not be suitable and may result in material degradation. Longer quarantine time can be considered; or, other methods such as application of heat may promote more rapid decontamination and may warrant further investigation. A literature review that will be available in October 2020 is exploring published research on the effect of heat, UV light, and other methods of disinfection. Organizations such as the Northeast Document Conservation Center<https://www.nedcc.org/free-resources/preservation-leaflets/3.-emergency-management/3.5-disinfecting-books> have shared information on disinfecting materials for archives, libraries and museums.
