Questions With Verified Answers.
First step of fecal accident procedure - answer✔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 - 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 - answer✔Formation of partial vacuums when the pump exceeds the water supply
Chlorine - answer✔A chemical element that exists as a gas in its elemental form or as a part of a
chemical compound that is an oxidant and a biocidal agent used in pool, spa, and hot tub
disinfection
Chlorine demand - answer✔The amount of chlorine necessary to destroy the germs, algae, and
other impurities in the water. Demand refers to the amount required before chlorine can be made
available to continue sanitizing the pool, spa, or hot tub water.
Chloramines - answer✔A compound formed when chlorine combines with ammonia, nitrogen,
or swimmer or bather wastes. They cause eye and skin irritation, and they have a strong
objectionable odor.
Chlorine residual - answer✔The amount of measurable chlorine remaining after treating water
with chlorine to disinfect and oxidize contaminants. It may also be explained as the amount of
chlorine left after satisfying the chlorine demand.
