Title Moldy Library Impacts California Students and Faculty
Introduction LA Testing provides analytical services, sampling supplies and indoor environmental quality test kits to identify microbial contaminants.

Huntington Beach, CA, January 22nd, 2018

Last month, the Long Beach Post published an article about the scheduled reopening of the second floor of a university library in California. According to their report, the second floor, containing hundreds of thousands of books, had been closed for several months following the discovery of mold. The mold is believed to have been a result of repair work done over the summer which allowed for a period of humidity control issues.

Housing books and manuscripts made of paper, libraries must be especially vigilant of indoor air quality (IAQ) issues to protect their vast collection of printed materials. One component of indoor air quality that is particularly crucial is the humidity level. Humidity can quickly increase if there has been water damage, if the library’s HVAC system has not been properly programed or is not working correctly. 

“There are many types of mold that will rapidly begin to grow on anything made out of paper as soon as moisture is introduced,” said Michael Chapman, Laboratory Manager at LA Testing’s Huntington Beach facility. “It’s critical in these types of sensitive environments that they are kept dry. The growth of mold in a library will not only destroy books, it could also become a health concern for people who work in or visit the library. Exposure to elevated levels of mold can cause allergies, act as a respiratory irritant and even trigger an asthma attack in some people.”   

To help facility managers and librarians control and recognize moisture issues in libraries, LA Testing offers humidity sensors, data logging instrumentation, moisture meters, and other air and surface testing equipment. LA Testing’s microbiology laboratory also offers mold and bacteria testing of indoor air quality, surfaces and materials. These testing services are not only instrumental for identifying microbial issues, they are also crucial for evaluating cleanup efforts if a mold event has already occurred.
