_______________ is a step by step plan that the facility staff will follow in response
to an emergency at the facility. - CORRECT ANS Emergency Action Plan
Most rescues and diving accidents occur in _____ water - CORRECT ANS
Shallow
Pool Operator certification is valid for _____ years - CORRECT ANS 2 years
Lifeguard certification is valid for ____ years - CORRECT ANS 2 years
Five factors figure into water balance: - CORRECT ANS 1. pH
2.Total Alkalinity
3. Calcium hardness
4. Temperature
5. Total Disolved Solids
Define : Corrosive Water - CORRECT ANS Seeks to satisfy its hunger by
dissolving virtually everything it contacts. Attacking metals and plaster surfaces.
Define: Scaling Water - CORRECT ANS Too many ingredients seeking to relieve
its condition by releasing precipitates either as scale, cloudiness or residue.
What is neutral pH? - CORRECT ANS 7
What is pH of human eye? - CORRECT ANS 7.5
What is acceptable value of pH? Main pool is tested every _____ hours and spa be
tested every ____ ? - CORRECT ANS 7.2 - 7.8 (Although ideal range is 7.4 - 7.6)
Main pool tested every 2 hours and spa tested every hour
How is pH tested? - CORRECT ANS Phenol Red or R-004
If pH is too high what needs to be added? - CORRECT ANS Muriatic Acid
If pH is too low what needs to be added? - CORRECT ANS Soda Ash ( sodium
carbonate)
What is Total Alkalinity represent? - CORRECT ANS The amount of carbonates,
bicarbonates and hydroxide in a solution.
What does Total Alkalinity information provide? - CORRECT ANS The measure
of the pH-buffering capacity, or the ability of a solution to resist change in pH. -- If the
alkalinity is too high then it will be difficult to either raise or lower the ph.
What is pH bounce? - CORRECT ANS If the alkalinity is too low, wide fluctuations
in the pH reading will occur. In these situations, the pH level will become so
unpredictable that it may change as frequently as hour to hour
What is acceptable Alkalinity values: _____ to _____? How often should it be tested
for main pool ____?
How often should it be tested for spa _____? - CORRECT ANS 60-180 ppm (
ideal range is 80-120 ppm with goal around 100)
Main pool: 1x a week
Spa: Daily
If Total Alkalinity is too High what needs to be added? - CORRECT ANS Muriatic
Acid
If Total Alkalinity is too Low what needs to be added? - CORRECT ANS Baking
Soda ( Sodium bicarbonate)
What is the difference between hard water and soft water? - CORRECT ANS
Hard water will produce scaling resulting in mineral deposits on wall or in pipes.
