Hazards of Pools without Ventilation

I open the outside doors at the indoor pool on my street. Even traffic fumes are better than having no air! Sadly the building owner refuses to fix the ventilation problem.

Indoor Pool Ventilation
Indoor swimming pools continuously produce large quantities of chlorine laden water vapor through the process of pool evaporation.

When water vapor has no escape from these air tight structures, it causes numerous problems such as:
blistering of paint,
deterioration of structural supports
and many other negative cosmetic effects on your building.

As a result repair or replacement of damaged items can be very costly and time consuming. Patrons and staff of indoor pools must also endure an unpleasant environment. They are surrounded in the physical discomfort of high humidity. The mold, mildew, bacteria and fungi that grow in these moist conditions can effect their health. These growths give off low-molecular weight volatile organic compounds (VOCs), many of which are poisonous and have potent odors.
Bathhouses, mechanical equipment rooms, storage areas and indoor swimming pool enclosures shall be ventilated, either by natural or mechanical means. Room ventilation shall prevent direct drafts on swimmers and shall minimize condensation. A minimum of two air changes per hour shall be provided for indoor pool areas. Heating units shall be kept from contact with swimmers. Fuel-burning heating
equipment shall be installed and vented to the outdoors in accordance with the Uniform Code.
