Protection Résumé : After confirming the presence of arsenic and lead in selected nineteenth-century books using XRF, the UC Berkeley Library Preservation Department and the UC Berkeley Office of Environment, Health and Safety conducted an exposure test to evaluate the risk of handling books for patrons and library staff. This test was designed to replicate a patron or conservator’s exposure levels while reading or mending a book that contains arsenic and lead. It involved handling one book for an hour, wearing fitted personal protective equipment (PPE), while taking air samples near the handler’s breathing zone, and subsequent wipe samples taken from the underlying surface and gloves used to handle the book. Results were compared with the CAL/OSHA action levels, the California Department of Health standard for lead contaminated dust, and the ‘World Trade Center Indoor Environment Assessment’ guidelines. Despite being anecdotal evidence, this case study contributes to an information gap that cannot be easily filled given that individual libraries do not have the resources to undertake a large-scale analysis of nineteenth-century materials.

Occupational Exposure Risk Assessment of Library Collections Work Tasks and Storage Areas in Studies in conservation, Vol.70 N°7-8(2025; October-November) (2025-10-01)

Conservation. Protection Résumé : Cultural heritage sites, including libraries where historical texts are available, are responsible to staff, research visitors, and the public for providing a safe and healthy work and educational experience. Identifying hazards inherent and acquired on collections, or in contaminated work areas and storage environments, has become more prevalent with the use of XRF analysis (for metals), knowledge of collector's notes, and records of conservation methods. However, this is only source identification data, that typically does not directly correlate to the potential health risk from specific work tasks and where routes of exposure exist. An occupational exposure assessment, conducted by a qualified health and safety professional, will determine actual risks during work tasks via personal sampling devices and media, surface and dermal wipes, and other methods. An exposure assessment case study is presented, related to the testing and assessment of worker exposure to and workspace contamination from selected metals (arsenic, chromium, lead, and mercury) within historical collections at a regional library. Personal sampling results quantified potential inhalation exposures, wipe samples verified the presence of contaminants on hands (potential ingestion risk), and surface wipe results identified cross-contamination in collection storage and work areas. Detailed recommendations for improved safe work practices, personal protection, and other controls were offered. Understanding hazard sources, routes of exposure, and surface transference defines both the potential health risk and the methods to best control that exposure. Safety and collection preservation and conservation are not disjointed topics. Safety can work hand in hand to support the protection of collections.
