Most families have the obvious pool risks filed away: watch the kids near the water, no running on the deck, go feet-first in shallow ends. Good instincts, all of them. But emergency rooms see pool-related visits every summer for reasons that never make the standard mental checklist, and a few of them are genuinely worth knowing.
Pool Chemical Injuries Are More Common Than People Expect
According to CDC data published in the Morbidity and Mortality Weekly Report, pool chemical injuries led to an estimated 4,535 emergency department visits annually in the United States between 2008 and 2017. About two thirds occurred during the summer swim season, and more than a third of patients were under 18.
The most common injury is inhalation, not skin contact. The top diagnosis in pool chemical ER visits, per the CDC, was poisoning from breathing in chemical fumes, most often when opening chlorine containers, handling chemicals in an enclosed space, or accidentally mixing products that should never be combined. Chlorine and muriatic acid are both standard in residential pool maintenance, and combining them can generate toxic chlorine gas. It does not take much to cause coughing, shortness of breath, and eye and throat burning that needs medical attention. Most of these incidents happen at home pools, not commercial ones.
If someone has had significant chemical exposure and is still symptomatic after getting fresh air, persistent cough, trouble breathing, or eye pain warrants an ER evaluation.
That “Pool Smell” Is Not Chlorine, and It Matters
The sharp chemical smell at an indoor pool is not free chlorine. It is chloramines, which form when chlorine reacts with urine, sweat, and organic matter in the water. The CDC has documented that chloramines, not chlorine itself, are what cause red eyes and respiratory irritation in pool environments. In poorly ventilated indoor facilities, chloramines can accumulate in the air above the water and trigger real respiratory symptoms, especially in people with asthma.
A pool that smells overwhelmingly chemical is actually a sign the water is off: too much biological load, not enough free disinfectant. Worth leaving, and worth knowing if symptoms follow someone home.
Drain Covers and Broken Equipment: The Risk That’s Largely Hidden Underwater
Pool drainage systems create powerful suction, powerful enough that a missing, cracked, or improperly sized cover can trap hair, limbs, or a swimmer’s body against the drain opening. The Virginia Graeme Baker Pool and Spa Safety Act, which took effect in 2008, required all public pools to install compliant anti-entrapment drain covers and the CPSC reported zero drain entrapment deaths at public pools in the decade that followed.
However, residential pools are a different story. The law’s cover requirements did not extend to private backyard pools, which means older drain covers at home pools may not meet current safety standards. A cracked, dislodged, or missing drain cover carries the same suction hazard it always did.
It is worth visually checking the drain cover before children get in any pool, particularly a residential one. If a cover looks damaged, sits loosely, or is absent entirely, that pool should stay empty until it has been inspected and repaired. Children with long hair should tie it up before swimming.
Skin Infections and Ear Infections That Start in the Water
Swimmer’s ear is one of the most common reasons a pool day ends with a medical visit. It develops when water stays in the ear canal long enough for bacteria to take hold, making the ear painful, itchy, and sometimes swollen. Children are especially susceptible. It responds well to antibiotic drops, but it should be evaluated rather than treated with home remedies, and tends to get more uncomfortable before it gets better if left alone.
Less familiar but real: a red, itchy rash appearing within a day or two of swimming, particularly on areas covered by a swimsuit. This is often folliculitis caused by Pseudomonas bacteria in poorly maintained water. Despite being nicknamed “hot tub rash,” the CDC documents it in pools and water playgrounds as well. Most cases clear on their own, but a rash that is spreading, worsening, or accompanied by fever is worth having looked at.
After a Scary Moment in the Water, Watch for a Few Hours
If someone inhales water during a close call in the pool, respiratory symptoms can develop in the hours that follow as the lungs respond to irritation. The American Red Cross and the American College of Emergency Physicians both note onset can begin within four to eight hours. A person who comes out of the water completely fine and stays that way is fine. But watch for:
- Persistent or worsening cough after leaving the water
- Labored breathing, chest pain, or visible effort to breathe
- Unusual fatigue or behavioral change in a child that doesn’t lift after resting
Symptoms that are getting worse, not better, are the cue to go in.
Trust the Instinct That Something Is Off
None of this is meant to make the pool feel dangerous. It isn’t, and Texas families should be out there all summer. But a few of these scenarios unfold quietly, and knowing what to look for makes the difference between catching something early and wondering for a week what went wrong.
Surepoint Emergency Centers are open across Texas around the clock, every day of the year. The team evaluates chemical exposures, post-submersion respiratory concerns, skin infections, dehydration, and fractures regularly through the summer months. On-site imaging and lab work mean a complete evaluation happens in one place, without referrals. When something feels off and you’re not sure it can wait, that’s exactly why we are here.
