Cassandra, the requirement for humidity covers requirements for equipment (specifications will specify operating conditions - temperature, humidity), chemicals (some are hygroscopic and high humidity can shorten shelf life) and "working environment." If you find that you need certain humidity levels for good results, or worker comfort, you can put that in your environmental procedures. The question is, what can you do about it to change the levels?
Besides those things, low humidity is a fire danger, and continuous high humidity can be an infection control concern. We set our humidity range at 20% to 60%. Here we never get to 20% but we sometimes go over 60% in some our labs on mild foggy days, mainly in older buildings.

Isn't there a CAP requirement requiring monitoring of the humidity as well as temperature in the actual lab not just where slides are stored?
