Legislation

In pharmaceutical applications, the majority of operations require humidity levels between 20% and 35% relative humidity.

1996 NFPA 99, Appendix A, recommends a relative humidity level of at least 50% in operating rooms because it helps to diffuse electrostatic charges.

One major consequence of poor humidity is mold. Since it is nearly impossible to eliminate all sources of mold spores inside a building once it is present, the main priority is to focus on adequate humidity levels to stop the spread of mold. (See mold section for further details.)
