							 A - Closure Requirements
Closure Event
Corrective Action Required
A. Free Chlorine = less than 1.0
							 pm
Close the facility. Determine the cause. Make
							 repairs or corrections.
B. pH of water = greater than 7.8
Close the facility. Determine the cause. Make
							 repairs or corrections.
C. pH of water = less than 7.2
Close the facility. Determine the cause. Make
							 repairs or corrections.
D. Inadequate lifeguards or
lifesaving equipment
Close the facility until the required number of
							 lifeguards and lifesaving equipment are provided.
E. Accident Resulting In:
Lifeguard leaving station OR Body fluids
							 discharged into water
Close facility until lifeguard returns to
							 station.
Follow fecal accident cleanup procedures
							 outlined below in item I if blood or feces are discharged into the
							 water.
F. Water Clarity Unsatisfactory
(Main drain or 6 inch black disk in the deepest
							 water on the bottom of a pool or spa not visible from the adjacent
							 deck)
Close the affected area until the main drain or
							 a six (6) inch black disk in the deepest water on the bottom of a pool or spa
							 is visible from the adjacent deck.
Determine cause. Make repairs or
							 corrections.
G. Free bromine = less than 2.0
							 ppm
Close the facility. Determine the cause. Make
							 repairs or corrections.
H. Equipment Failure - Main pump, disinfectant
							 feed equipment, or main drain covers.
Close the facility immediately upon main pump
							 failure. Close the facility when disinfectant feed equipment fails and free
							 chlorine falls below 1.0 ppm or free bromine falls below 2.0 ppm. Repair
							 equipment. Test and balance chemical parameters prior to re-opening the
							 recreational water facility. Close facility if main drain covers are missing,
							 loose, or broken. Replace, secure, or repair as required.
I. Fecal Accident or Release of
Blood or Vomitus into Water *
Follow Cleanup Procedure A if:
A formed stool, visible blood, or vomit is
							 discharged into the water.
Follow Cleanup Procedure B if:
A loose stool (e.g. diarrheal fecal accident)
							 is discharged into the water.
Evacuate patrons from all water contaminated
							 with fecal material. Do not let anyone back into the water until all
							 decontamination procedures are completed.
Remove as much fecal material as possible using
							 a net or scoop and dispose of in a sanitary manner. Clean and disinfect the net
							 or scoop (e.g. after cleaning, leave the net or scoop immersed in the pool
							 during disinfection). VACUUMING STOOL AND VOMITUS FROM THE WATER IS NOT
							 RECOMMENDED.
_
Proceed to procedure A or B as
							 required.
Cleanup Procedure
							 A
1. Raise free chlorine to 2 ppm, adjust pH to
							 between 7.2-7.5, and maintain for at least 25 minutes before letting anyone
							 back into the water.
2. Ensure that the filtration system is
							 operating during this entire process.
Cleanup Procedure
							 B
1. Raise chlorine to one of the following
							 concentrations, maintain for the corresponding time, and adjust pH to between
							 7.2-7.5:
a. 5ppm free chlorine for 32
							 hours;
b. 10 ppm free chlorine for 16
							 hours;
c. 15 ppm free chlorine for 12
							 hours;
d. 20 ppm free chlorine for 8
							 hours.
2. Ensure that the filtration system is
							 operating during the entire process.
3. Backwash the filter thoroughly or clean the
							 filter media after maintaining the required free chlorine concentration and
							 time.
4. Adjust free chlorine concentration to less
							 than 5 ppm before letting anyone back into water.
Cleanup Procedures A & B
Establish a fecal accident log. Document each
							 fecal accident by recording date and time of event, note whether formed stool
							 or diarrhea, and note the chlorine levels at the time or observation of the
							 event. Before allowing anyone back into the water, record the pH , the
							 procedures followed in response to the fecal accident (including the process
							 used to increase chlorine levels if necessary), and the contact
							 time.
