Quality Control & Process Improvement Flashcards

Which of the following BEST describes the purpose of a hazard analysis in aquatic facility quality management?

Answer: To identify steps in the operation where failures could cause illness or injury

Hazard analysis identifies critical points in pool operations where failures could lead to waterborne illness or safety incidents.

A pool's combined chlorine (chloramine) level measures 0.7 ppm. What corrective action is indicated?

Answer: Perform breakpoint chlorination by raising free chlorine to at least 7.0–10.5 ppm

Breakpoint chlorination requires adding enough chlorine (approximately 10x the combined chlorine level) to oxidize chloramines.

An operator wants to reduce chemical waste and cost while maintaining water quality. Which process improvement technique is MOST applicable?

Answer: Lean management principles to eliminate over-dosing and waste

Lean management focuses on eliminating waste and inefficiency, which in pool operations includes chemical over-dosing.

During an audit, an inspector finds that chemical test results are recorded only at the beginning and end of operating hours. What risk does this create?

Answer: Out-of-range conditions during peak hours may go undetected and unaddressed

Infrequent testing creates gaps where water quality can deteriorate to unsafe levels without detection, especially during high bather loads.

What is the primary benefit of using an Automatic Chemical Controller (ACC) as part of a quality improvement program?

Answer: It provides continuous monitoring and reduces chemical fluctuations

ACCs continuously measure and dose chemicals, minimizing the peaks and valleys in chemical levels that occur with manual dosing.

A facility's incident log shows a pattern of skin and eye irritation complaints every Saturday afternoon. What quality control step should the operator take?

Answer: Analyze bather load, chemical logs, and ventilation data for Saturday afternoons

Correlating complaints with operational data (bather load, chemical levels, timing) helps identify root causes of recurring problems.

Which MAHC-aligned practice BEST supports a culture of continuous improvement in aquatic facilities?

Answer: Regular staff training, documented audits, and corrective action follow-up

Continuous improvement requires trained staff, systematic auditing, and tracking corrective actions to verify effectiveness.
