What is the most important factor related to pool water chemistry?
650mV
HOCl
300-600ppm
pH
Term 3 of 48
When are chloramines formed?
under a heavy organic load with low chlorine levels, often with limited air movement
when chlorine is added in excess to a clean pool
during the filtration process of pool water
when the pool is shocked with high doses of chemicals
,Term 4 of 48
What is NOT one of the AFO's primary responsibilities?
Teaching Lessons
Facility Inspection
Special Pools
Building Instruments
Term 5 of 48
What is oxidation?
the process of filtering out dirt and debris from the pool
a chemical process that destroys organic compounds in the pool water
a technique for balancing ph levels in the water
a method of adding chlorine to the pool
Term 6 of 48
What are the two types of pumps?
Self-Priming and Flooded Suction Centrifugal
Facility Inspection
Under a Heavy Organic Load with Low Chlorine Levels, Often with Limited Air Movement
Heated and Treated Water is Equally Distributed in the Pool
Term 7 of 48
What does sanitation do?
destroys bacteria
absence of microbes
inhibits bacterial growth
without infection
,Term 8 of 48
When is HOCl produced?
When chlorine gas is released from a chemical reaction
During the evaporation of water in a swimming pool
When water is heated to a boiling point
Upon gas chlorine, sodium hypochlorite (bleach) or calcium hypochlorite being added
to water
Term 9 of 48
What is the most influential variable in the CSI?
300-600ppm
650mV
pH
HOCl
Term 10 of 48
What do chemical controllers NOT replace?
orp and ph
pool operator
when flooded
wear protective equipment
Term 11 of 48
What is total Alkalinity?
this is an index of the water's resistance to pH change
this measures the amount of chlorine present in the water
this indicates the temperature stability of pool water
this refers to the total amount of dissolved solids in water
, Term 12 of 48
Why is HOCl the desirable chlorine compound?
a chemical process that destroys organic compounds in the pool water
liquid filter acids
because calcium carbonate is more likely to form on elevated temperatures
because it oxidizes AND sanitizes
Term 13 of 48
When do gutters NOT work?
pool operator
when flooded
(tc)-(fc) = combined chlorine
wear protective equipment
Term 14 of 48
For CSI, what does negative/positive mean
(tc)-(fc) = combined chlorine
Negative = aggressive
Positive = scaling
Eye wash station
Orp and ph
Term 15 of 48
Safety considerations for chemical handling require what?
safety shower
emergency shower
goggles
eye wash station
