What is water quality management for school pools? Daily procedures [Basic knowledge]

What should be checked before use, when to retest during class, and what to leave behind after it's finished? We will follow the water quality management of the school pool for one day according to the standards.

The water in the school's swimming pool is managed in accordance with the school environmental health standards established by the government based on the School Health and Safety Act. In addition to regular water quality tests, daily inspections for the days of use are also specified by the standards. Here, we will organize the checks according to the daily flow of the person in charge. ■ Four items to check before use 1. In the water: Ensure there are no hazardous substances or abnormalities. 2. Free residual chlorine: At least 0.4 mg/L in any part. 3. pH value: Maintained at the standard level. 4. Clarity: The wall should be clearly visible from a distance of 3 meters underwater. Before swimming, also check that the covers of the drainage and circulation water intake are secured with screws or bolts. This is an important check related to the safety of swimmers. ■ What if there is not enough chlorine? If it is below the standard, stop swimming and increase the amount of chlorine agent injected. Allow swimming only after confirming it has returned to above 0.4 mg/L. ■ What if the wall is hard to see? If the wall 3 meters ahead is not clearly visible underwater, operate the circulation filtration system sufficiently until it becomes visible, or replace the water.
