Nationally, drowning is a leading cause of death to children under five.

The key to preventing these tragedies is to have layers of protection. This includes placing barriers around your pool to prevent access, using pool alarms, closely supervising your child and being prepared in case of an emergency. CPSC offers these tips to prevent drowning:

Fences and walls should be at least 4 feet high and installed completely around the pool. Fence gates should be self-closing and self-latching. The latch should be out of a small child's reach.

If your house forms one side of the barrier to the pool, then doors leading from the house to the pool should be protected with alarms that produce a sound when a door is unexpectedly opened. A power safety cover -- a motor-powered barrier that can be placed over the water area -- can be used when the pool is not in use.

Keep rescue equipment by the pool and be sure a portable phone is poolside with emergency numbers posted. Knowing cardiopulmonary resuscitation (CPR) can be a lifesaver.

For above-ground pools, steps and ladders to the pool should be secured and locked or removed when the pool is not in use.

If a child is missing, always look in the pool first. Seconds count in preventing death or disability.

Pool alarms can be used as an added precaution. Underwater pool alarms generally perform better and can be used in conjunction with pool covers. CPSC advises that consumers use remote alarm receivers so the alarm can be heard inside the house or in other places away from the pool area.

PARENTS AND GUARDIANS: ONLY YOU CAN PREVENT A DROWNING. WATCH YOUR CHILD CLOSELY AT ALL TIMES. MAKE SURE DOORS LEADING TO THE POOL AREA ARE CLOSED AND LOCKED. YOUNG CHILDREN CAN QUICKLY SLIP AWAY AND INTO THE POOL.
