Establish a fecal accident log documenting....? - CORRECT ANS (1) the date and time of the event (2) if the accident is a result of a form stools or diarrhea (3) The free available chlorine concentration at the time or observation of the event and before opening the public pool (4) The pH (5) The procedures followed to respond to the fecal accident including the process used to increase free chlorine residual if necessary (6) The contact time Procedures for form stool that is solid and not liquid - CORRECT ANS Raise the free available chlorine level to 2 ppm and ensure that the pH is between 7.2 and 7.5 Maintain the chlorine concentration for at least 25 minutes.
