What are some common ways near drownings can occur?

Children are most likely to suffer a drowning or near drowning in home swimming pools. However, drownings are also common in natural waters such as lakes, rivers, or oceans, any open body of water. Drowning can occur while the child is swimming, if they unexpectedly begin to breathe in water while at play, if they fall into the water from a pool deck, vessel or the shore, or if they suffer a medical condition that causes them to lose consciousness.
