What is the lifeguard to swimmer ratio? - Correct Answers -50-1
Certified Pool Operator must be how far in order for the pool to open? - Correct
Answers -15 minutes
How often should readings for pH and chlorine take place - Correct Answers -every 1
hour
How long do records need to be held? - Correct Answers -2 years at the pool and 3
years total
What is they key to a safe facility? - Correct Answers -Prevention
Most drownings of victims happen when? - Correct Answers -under 4 feet of water
under 4 feet tall
under 7 years old
where to put the heater ? - Correct Answers -after the filter and before the chemical
injection points
chemical feeders - Correct Answers -introduce the disinfectant chemical and pH
adjusters to filtered water
Sand filters - Correct Answers -- water goes into filter through the filter influent line
-goes to the diffuser (evenly distributes water through a sand bed)
, -Laterals (rungs located in the bottom of the filter tank)
laterals - Correct Answers --rungs located in the bottom of the filter tank
when broken sand can get in them and go into the return line
What does water balance consist of? (5) - Correct Answers -pH, Total Alkalinity,
Calcium Hardness, Temperature, and Total Dissolved solids
(chlorine only disinfects water, it does not maintain sanitary qualities)
when does corrosive water happen? - Correct Answers --when the water balance is too
low
-satisfies its hunger by dissolving it comes in contact with
-attacks metals and iron
When does scaling water happen? - Correct Answers -- when water balance is too high
-relieve its overfed condition by releasing precipitates as scale , cloudiness, and residue
what is pH? - Correct Answers -how basic or how acidic a solution is
explain the pH scale. - Correct Answers -0-6: acidic
7: neutral
8-14: basic
what is the pH of the human eye? - Correct Answers -7.5 --> so a pool should try to
maintain 7.5 also
Health Department regulation for pH and how often it should be checked - Correct
Answers -7.2-7.8 and every 1 hour for pool and spa
what is phenol red? - Correct Answers --what the pH value is tested with
If the pH of the water is too high what should you do? - Correct Answers -1. Muriatic
Acid (12 oz per 10,000 gallons to decrease pH by 0.2 units)
2. Sodium Bisulfate/ Dry Acid (1 lb per 10,000 gallons)
3. Carbon Dioxide
If the pH of the water is too low what should you do? - Correct Answers -Sodium
Carbonate (Soda Ash) - 6 oz per 10,000 gallons to increase pH by 0.2
What is Total Alkalinity - Correct Answers -- represents the amount of carbonates,
bicarbonates, and hydroxides in a solution
- the ability if a solution to resist change in pH
pH Bounce - Correct Answers -when the total alkalinity is too low their will be wide
fluctuations of pH (can be so unpredictable it can change hour to hour)
