I just would like to hear the policy most facilities have on indoor pool closure for lighting. I usually go by the 10 sec flash bang method just as the standard. I know some say no record of injuries for indoor pools and more dangerous clearing pool just want to find out the standard . I started at a new pool which has been using weather apps to find out how far away lighting is to the pool to determine closure.
Our facility does not close for thunder/lightning.
