Drowning
People drown when they get too much water in their lungs. You can drown in as little as an inch or two of water. Babies can drown in a sink or bathtub. Preschoolers are most likely to drown in a swimming pool. People who have seizure disorders are also at risk in the water. Drowning can happen quickly and silently.
