Swimming pool operator certification| 103 QUESTIONS| WITH COMPLETE SOLUTIONS First step of fecal accident procedure Direct all bathers to leave the pool. All affected waters must be closed to swimming until proper procedures for contamination have been completed Second step of fecal accident procedure Manually remove as much of the material as possible using a net or scoop and dispose of it in a sanitary manner. Clean and disinfect the scoop or net. After cleaning leave the net or scoop immersed in the pool during this infection. Vacuuming the stool is not allowed. Establish a fecal accident log documenting....? (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 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. Ensure this concentration is found throughout all waters by sampling at least three widely spaced locations away from return outlets Procedures for diarrhea liquid or non-form stools Raise the free available chlorine level two 20 ppm and ensure that the pH is between 7.2 and 7.5 Maintain the chlorine concentration and pH for eight hours while ensuring that the filtration system is operating. Backwash the filter thoroughly discharging the effluent directly to waste. Where appropriate replace the filter media Bathers may be allowed into pool after chlorine concentration has been returned to normal operating ranges Acid demand The amount of acid required to reduce pH and alkalinity to the correct range Algae Microscopic plant like organisms that grow in water do to warm temperatures and in adequate sanitizer. Algae can be green blue green black or yellow green (mustard). Alkalinity A measure of the ability of pool water to resist changes in pH. Buffering capacity of water. Balanced water The correct ratio of hardness, alkalinity, temperature, dissolved solids, and pH that prevent pool water from being either corrosive or scale forming
