home > monitoring your library > assessing your hygrometer readings

If you do find areas in your library that are regularly more humid than others, it may be an indication of more serious building problems.

What to Look For:

  • Look for signs of leaks or condensation in the building or plumbing and work with your city manager, building owner or landlord to have these issues fixed.
  • If you do not see signs of leaks or water damage to the building that could be causing higher humidity levels, the area may simply have low air circulation.
  • Use a fan in this part of your library to increase air circulation. This makes it less likely for mold spores to settle on surfaces where the higher humidity could support mold growth.
  • Work with your city manager, building owner or landlord to determine other strategies for long-term solutions, as well.

If you think you have a compromised building, more drastic measures may need to be taken. See the sections on Prevention, Assessing Mold Risks, Signs of a Compromised Building and Collection Maintenance for a starting point to deal with more serious situations.
