●● Second step of fecal accident procedure
Answer: 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....?
Answer: (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
Answer: 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
Answer: 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
Answer: The amount of acid required to reduce pH and alkalinity to the
correct range
●● Algae
Answer: 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
, Answer: A measure of the ability of pool water to resist changes in pH.
Buffering capacity of water.
●● Balanced water
Answer: The correct ratio of hardness, alkalinity, temperature, dissolved
solids, and pH that prevent pool water from being either corrosive or
scale forming
●● Bromine
Answer: A chemical element that exists as a liquid in its elemental form
or as part of a chemical compound that is an oxidant and a biocidal agent
used to disinfect pool, spa and hot tub water.
●● Bromamine
Answer: Bromine-ammonia compounds formed when the bromine in the
water combines with ammonia, nitrogen or swimmer or bather waste.
Unlike Chloramines they do not smell or irritate the body. They are
active sanitizers.
●● Calcium hardness
Answer: The amount of dissolved calcium in the pool. High levels
promote scale and cloudy water. Low levels promote corrosion of the
pool or spa equipment.
●● Cavitation
