Who is required to perform and document total chlorine testing for a central water system?

The requirement for total chlorine testing in a central water system is particularly important for ensuring water safety and quality, especially in healthcare settings such as dialysis clinics. The presence of two staff members performing this task, which includes the nurse in charge, adds a level of oversight and accountability to the process. This dual involvement helps prevent errors and ensures that proper protocols are followed.

Having a nurse in charge as part of the testing team guarantees that a licensed healthcare professional is involved, which is crucial for interpreting results and taking appropriate action if chlorine levels are outside acceptable parameters. This collaborative approach not only enhances the reliability of testing but also ensures compliance with health and safety regulations, reducing the risk of contamination and safeguarding patient health.

Involving just one staff member or any available staff member lacks the checks and balances necessary for accurate testing and may not meet regulatory requirements. Similarly, the role of a quality assurance officer, while vital for overall compliance and monitoring, may not directly pertain to the hands-on aspect of performing and documenting total chlorine tests. Thus, the most appropriate option is for two staff members, including the nurse in charge, to conduct and document these essential tests.
