AFO Aquatic Facility Operator study plan
AFO Aquatic Facility Operator · Give each week a clear focus.
8 weeks · About 6 hours per week
Water Chemistry and Disinfection
Differentiate free chlorine, combined chlorine, and total chlorine, and compute combined chlorine from paired test readings
Explain how pH and cyanuric acid shift the balance between hypochlorous acid and hypochlorite ion, and rank sanitizer effectiveness at pH 7.0, 7.5, and 8.0
Calculate the dose required to reach breakpoint chlorination given a measured combined chlorine level
List at least six factors that depress ORP readings at a constant free chlorine residual
Describe the correct storage, handling, and PPE requirements for chlorine and acid, including why they must never be mixed or co-stored
Your checkpoint
Score 80% or higher on a self-made 25-question chemistry quiz and submit a one-page formula sheet with eight fully worked calculations (dose, residual, breakpoint, ppm-to-ounces conversions)
Filtration and Circulation
Calculate pool volume, turnover time, and required flow rate for rectangular, circular, and irregular pools
Compare sand, cartridge, and diatomaceous earth filters on design flow rate, filtration rate, and backwash or cleaning trigger
Explain head loss and read a pump curve to determine whether a system is operating on the flat or steep part of the curve
Size filter surface area and pipe/pump capacity for a specified turnover requirement
Describe how skimmers, gutters, surge tanks, and equalizer lines maintain circulation and water level
Your checkpoint
Produce a worked calculation packet for a 75,000-gallon pool: volume, turnover at two turnovers per day, required gallons per minute, sand filter area at 15 gpm/ft², and backwash frequency - verified against eight practice problems
Facility Safety and Risk Management
Identify entrapment hazards and explain how anti-entrapment drain covers, secondary systems, and the federal pool safety law apply to an existing facility
Outline the components of an emergency action plan, including roles, signals, and post-incident steps
Define zones of patron surveillance and explain how to assign and rotate coverage
Conduct a walk-through hazard audit covering decks, ladders, depth markings, signage, and electrical/water interfaces
Explain bather load calculations and how capacity limits affect supervision and water quality
Your checkpoint
Draft a one-page emergency action plan outline plus a 15-item hazard inspection checklist, and score 80% or higher on a 20-question safety and risk management quiz
Maintenance and Equipment
Build a preventive maintenance calendar covering pumps, motors, filters, chemical feeders, heaters, and safety equipment
Diagnose six common equipment faults (loss of prime, high filter pressure, cloudy water after backwash, heater short-cycling, feeder drift, cavitation) from symptoms
Calibrate a chemical feed pump by calculating desired output in milliliters per minute and verifying with a drawdown test
Explain heater and heat exchanger maintenance, including scale control and the risk of low flow
Specify the records a facility must keep for equipment service and chemical use
Your checkpoint
Submit a 30-day preventive maintenance calendar with at least 20 scheduled tasks and a troubleshooting matrix matching six equipment faults to likely causes and corrective actions
Pool Operations and Staffing
Write opening, mid-day, and closing procedures that assign specific tasks to specific roles
Design a four-week in-service training rotation that covers surveillance, rescue drills, chemical handling, and customer communication
Calculate staffing needs from bather load, zone coverage, and break requirements
Explain how to document daily operations, incidents, and staff training in logs that satisfy an inspector
Describe how to onboard and evaluate a new operator or lifeguard through the first 30 days
Your checkpoint
Produce a 25-item daily operations checklist (opening, mid-day, closing) plus a four-week in-service training schedule with named topics, durations, and sign-off lines
Regulations and Health Codes
Locate and cite the specific permit, inspection, and reporting requirements that apply to a public aquatic facility in your jurisdiction
List required water testing frequencies, acceptable ranges, and the log entries an inspector will ask for
Apply the CDC-recommended response to formed-stool, diarrheal, and vomit incidents, including hyperchlorination targets and contact times
Explain record retention requirements for chemical, testing, staffing, and incident documentation
Map required signage and safety equipment to the code provision that mandates each one
Your checkpoint
Build a compliance table mapping 15 regulatory requirements to the exact record, log entry, or physical item that proves compliance, and score 80% or higher on a 20-question codes quiz
Water Chemistry and Disinfection & Filtration and Circulation & Facility Safety and Risk Management & Maintenance and Equipment
Re-attempt every missed question from weeks 1 through 6 and write the corrected reasoning for each
Re-solve the calculation types that produced errors: turnover, filter area, breakpoint dose, and feeder calibration
Teach back the pH–chlorine relationship and the entrapment hazard hierarchy in your own words without notes
Run a timed mixed set of 40 questions drawn from the four heaviest domains and analyze the error pattern
Your checkpoint
Complete an error log listing every missed question with the corrected answer and the underlying rule, then score 85% or higher on a second attempt at the week 4 cumulative quiz
Water Chemistry and Disinfection & Filtration and Circulation & Facility Safety and Risk Management & Maintenance and Equipment & Pool Operations and Staffing & Regulations and Health Codes
Complete two full-length timed practice exams under exam conditions and review every answer
Drill the highest-frequency facts: residual ranges, turnover targets, breakpoint multiplier, incident response chlorine levels, and required records
Rebuild the formula sheet into a final one-page reference covering chemistry, hydraulics, and dosing
Practice explaining three regulatory or safety scenarios aloud as if answering a scenario question
Your checkpoint
Score 85% or higher on both timed 100-question practice exams and submit a final one-page master reference sheet
Milestones
