Which of the following statements is true regarding chemical safety?

The statement emphasizing that chemicals should always be added to water is critical for ensuring safety in pool operation. When adding chemicals, particularly concentrated substances like chlorine, introducing them to water minimizes the risk of violent reactions, such as splashing or generating harmful gases. Pouring water into chemical products, on the other hand, can cause hazardous reactions, including overheating or splattering.

The practice of adding chemicals to water allows for more controlled mixing and reduces the potential for injury or damage that could arise from improper handling. This fundamental safety protocol is crucial for maintaining a safe pool environment and protecting both the operator and patrons.

In contrast, mixing chemicals, switching scoops, or loosely storing chemicals can lead to misinformation about their handling and storage practices, increasing the risk of accidents and exposure.
