Is it safe to swim in a pool with chlorine level of 5?

No, it is not safe to swim in a pool with a chlorine level of 5. The ideal chlorine level for a swimming pool is between 1 and 3 ppm (parts per million). A chlorine level of 5 ppm is considered to be too high and can irritate the skin, eyes, and respiratory system. It can also lead to the formation of harmful disinfection byproducts, such as trichloramines. For these reasons, it is important to maintain the chlorine level in a swimming pool within the recommended range.
