i. An inspector must ensure that swimming pool equipment is being handled
and maintained correctly. The important features of chlorine gas containers and their
care are discussed in this lesson. Commonly used filtration equipment, operational
problems, and tests for adequate filter function are also discussed.
j. Another important item to inspect is algae control procedures. The
unpleasant and dangerous features of algae growth, early detection, and control
methods are presented in this lesson.
k. Accidents and drowning deaths are another problem in swimming pool
operation. An inspector should determine that equipment is correctly used and
maintained and that no dangerous conditions exist. Lifeguards and lifesaving
equipment should be present according to standards.
l. The routine inspection is primarily a check on pool operations and
maintenance procedures. Policies concerning the frequency, time, and method for
conducting the inspection are discussed and a sample inspection checklist is shown.
m. The routine inspection includes bacteriological studies, pH testing, and testing
for free available chlorine. Common tests for these items and testing techniques are
n. Natural bathing areas present special problems because they cannot be
controlled as swimming pools can be controlled. Disease hazards come from three
organisms: coliform bacteria, entamoeba histolytica, and the helminths causing
schistosomiasis. In addition, accidents and drowning occur at natural swimming areas
due to the lack of control.
o. Natural swimming areas must be surveyed carefully, including bacteriological
sampling. The inspector can then determine whether the site is acceptable for
swimming. Natural swimming areas are classified according to the number of coliform
organisms present in the sample. An inspector must also check that safety measures,
such as lifeguard requirements and the use of buoys, marking signs, and lifesaving
equipment, are being followed.
