Preventing Pool Chemical Injuries: A Quick Guide for Health Departments and Operators

May 19, 2025 | Anu Varma

Chemicals are used in pools, hot tubs, spas, and water playgrounds to protect swimmers from harmful germs and to prevent outbreaks. Some chemicals aid in disinfection, such as controlling pH levels, while others enhance water quality, prevent equipment corrosion and scaling, and combat algae growth. However, when pool chemicals are mixed incorrectly or personal protective equipment is not used during handling, they can pose a risk of injury. Be sure to follow our safety recommendations as well as the manufacturer’s instructions to handle these chemicals safely.

Pool chemical injuries such as skin rash, eye irritation, chemical burns, and pulmonary edema, result in approximately 4,500 emergency department visits annually, with at least one-third of the patients being under 18 years old.

This quick reference guide can be used by local, state, tribal, and territorial health departments and aquatic venue pool operators to develop an emergency response plan to ensure that you are prepared for what to do before, during, and after a pool chemical emergency.
