Drowning is often a "silent death" because a victim is usually unable to splash violently or call for help, as one might expect. According to the Centers for Disease Control and Prevention, drowning is the second leading cause of death for children 1-14 years old, and an extensive study performed by the Consumer Product Safety Commission (CPSC) found that "75 percent of the children involved in swimming pool submersion or drowning accidents were between 1 and 3 years old." In addition, the CPSC's study revealed the following statistics:

• Most of the victims were being supervised by one or both parents when the swimming pool accident occurred.
• Nearly half of the child victims were last seen in the house before the pool accident occurred. Twenty-three percent of the victims were last seen on the porch, patio, or in the yard.
• Sixty-nine percent of the children who became victims in swimming pool accidents were not expected to be in or at the pool, but were found drowned or submerged in the water.

Protecting children from drowning or becoming submerged in a backyard swimming pool requires more than just a single safety device or barrier. Providing "layers of protection" is the best strategy for keeping children safe in and around the pool area.

Pool Fence or Barrier

The first layer of protection is the barrier that surrounds the pool area; generally, this is a pool fence or wall. Fences or other barriers on the perimeter of the pool area should be at least four feet high, and the spaces between slats or holes in the barrier should be small enough to prevent a child from gaining a handhold or foothold which would allow them access to the other side of the barrier. Opportunities for a child to get over, under, or through a barrier should not exist.

Any gates in the fence or wall that surround your backyard swimming pool should have the ability to close and latch by themselves so that there is no danger of the gates standing open for any length of time. In addition, gate latches should be placed out of the reach of children. An open gate or an easily reachable gate latch may be an invitation to a young child to explore your backyard swimming pool.

Door Alarm

Installing a door alarm may be necessary if one or more of the outside walls of your house acts as part of the barrier around the pool. Any door and/or screen that leads from the house to the pool area should be equipped with an alarm that sounds if the door is opened. Door alarms should be designed to sound within 7 seconds after a door is opened and for a duration of at least 30 seconds, and the sound of the door alarm should be loud and distinct to avoid confusing it with another alarm that may be in the house. In addition, door alarms should be equipped with a switch or keypad to allow adults to enter or leave through the door without the alarm sounding. This switch or keypad should be mounted high on the interior wall out of a child
