Code
Blood contamination of a properly maintained AQUATIC VENUE’S water does not pose a public health risk to swimmers.
Annex
If the CHLORINE or bromine residual and pH are in a satisfactory range, there is no public health reason to recommend closing a POOL due to blood contamination. Data suggest that the risk posed by potential bloodborne pathogens is greatly diminished by dilution and normal FREE CHLORINE RESIDUAL levels. However, the operator may wish to temporarily close the POOL for aesthetic reasons or to satisfy PATRON concerns.
