Swimming pools should always be happy places.
Unfortunately, each year thousands of American families confront swimming
pool tragedies, drowning's and near drowning's of young children. These
tragedies are preventable. These are guidelines for pool barriers that can
help prevent most submersion incidents involving young children. This
designed for use by owners, purchasers, and builders of residential pools,
spas, and hot tubs. These guidelines are not intended as the sole method
to minimize pool drowning of young children, just helpful safety tips for
safer pools.

Each year, hundreds of young children die and thousands come close to death
due to submersion in residential swimming pools. CPSC has estimated that
each year about 300 children under 5 years old drown in swimming pools.
Hospital emergency room treatment is required for more than 2,000 children
under 5 years of age who were submerged in residential pools. CPSC did an
extensive study of swimming pool accidents, both fatal drowning's and
near-fatal submersions, in California, Arizona and Florida, states in which
home swimming pools are very popular and in use during much of the year.
 | In California, Arizona and Florida,
drowning was the leading cause of accidental
death in and around |
the home for children under the age of 5 years.
 | 75 percent of the children involved in swimming pool
submersion or drowning accidents were |
between 1 and 3 years old.
 | Boys between 1 and 3 years old were the most likely
victims of fatal drowning's and near-fatal submersions in residential
swimming pools. |
 | 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. In addition, 23 percent of the
accident victims were last seen on the porch or patio, or in the yard.
|
 | This means that fully 69 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.
|
 | 65 percent of the accidents occurred in a pool owned by
the victim’s immediate family, and 33 percent of the accidents occurred in
pools owned by relatives or friends. |
 | Fewer than 2 percent of the pool accidents were a
result of children trespassing on property where they didn’t live or
belong. |
 | 77 percent of the swimming pool accident victims had
been missing for five minutes or less when they were found in the pool
drowned or submerged.
|
The speed with which swimming pool
drowning's and submersions can occur is a special concern:
 | By the time a child’s absence is noted,
the child may have drowned. Anyone who has cared for a toddler knows how
fast young children can move. Toddlers are inquisitive and impulsive and
lack a realistic sense of danger. These behaviors, coupled with a child’s
ability to move quickly and unpredictably make swimming pools particularly
hazardous for households with young children.
|
 | Swimming pool drowning's of young
children have another particularly insidious
feature: these are silent deaths. It is
unlikely that splashing or screaming will
occur to alert a parent or caregiver that a
child is in trouble. The best way to reduce
child drowning's in residential pools was
for pool owners to construct and maintain
barriers that would prevent young children
from gaining access to pools. However,
there are no substitutes for diligent
supervision. |
Why the Swimming Pool Guidelines Were
Developed
 | Young child can get
over a pool barrier if the barrier is
too low or if the barrier has handholds or
footholds for a child to use when
climbing. The guidelines recommend that the top of a pool barrier be at
least 48 inches above grade, measured on the side of the barrier which
faces away from the swimming pool. Eliminating handholds and footholds
and minimizing the size of openings in a barrier’s construction.
|
 | For a solid barrier no
indentations or protrusions should be present,
other than normal construction tolerances
and masonry joints. For a barrier (fence) made up of horizontal
and vertical members if the distance between
the tops of the horizontal members
is less than 45 inches, the horizontal members should be
on the swimming pool side of the fence.
The spacing of the vertical members should not
exceed 1-3/4 inches. This size is based
on the foot width of a young child and is
intended to reduce the potential for a
child to gain a foothold. If there are
any decorative cutouts in the fence, the space
within the cutouts should not exceed
1-3/4 inches. |
How to Prevent a Child from
Getting OVER a Pool Barrier:
 | A successful pool barrier prevents a child from
getting OVER, UNDER, or THROUGH and
keeps the child from gaining access to
the pool except when supervising adults are
present. |
The Swimming Pool Barrier Guidelines:
 | If the distance between the
tops of the horizontal members is more than 45
inches, the horizontal members |
can be on the side of the fence facing
away from the pool. The spacing between
vertical members should not
 | exceed 4 inches. This size is based on the head
breadth and chest depth of a young child
and is intended to
prevent a child from passing through an
opening. Again, if there are any decorative
cutouts in the fence, |
the
space within the cutouts space within should not
exceed 1-3/4 inches.
 | For a chain link fence the mesh size
should not exceed 1-1/4 inches square unless slats, fastened at the
|
top or bottom of the fence, are used to reduce mesh openings to no more than
1-3/4 inches.
 | For a fence made up of
diagonal members (latticework)
the maximum opening in the lattice
should |
not exceed 1-3/4 inches.
 | Aboveground pools should have barriers.
The pool structure itself serves as a barrier or a barrier is mounted |
on top of the pool structure. Then, there are two possible ways to prevent
young children from climbing up
into
an aboveground pool. The steps or ladder can be designed to be secured,
locked or removed to prevent
access,
or the steps or ladder can be surrounded by a barrier such as those
described above. For any pool
barrier,
the maximum clearance at the bottom of the barrier should not exceed 4
inches above grade, when
the
measurement is done on the side of the barrier facing away from the pool.
 | If an aboveground pool has a barrier on
the top of the pool, the maximum vertical clearance between the top of the
pool and the bottom of the barrier should not exceed 4 inches. Preventing
a child from getting through a pool barrier can be done by restricting the
sizes of openings in a barrier and by using self-closing and self-latching
gates.
|
 | To prevent a young child
from getting through a fence or other
barrier, all openings should be small enough
so that a 4-inch diameter sphere cannot
pass through. This size is based on the
head breadth and chest depth of a young child.
|
There are two kinds of gates which might
be found on a residential property. Both can play a part in the design of a
swimming pool barrier:
 | Pedestrian Gates
are the gates people walk through. Swimming
pool barriers should be equipped
with a gate or gates which restrict
access to the pool. A locking device should be
included in the gate design. Gates
should open out from the pool and should be
self closing and self-latching. If a
gate is properly designed, even if the
gate is not completely latched, a young child pushing
on the gate in order to enter the pool
area will at least close the gate and may
actually engage the latch. When the release
mechanism of the self-latching
device is less than 54 inches from the
bottom of the gate, the release mechanism for
the gate should be at least 3 inches
below the top of the gate on the side
facing the pool. Placing the release mechanism
at this height prevents a young child
from reaching over the top of a gate and
releasing the latch.
Also, the gate and barrier should have no
opening greater than 1/2 inch within
18 inches of the latch release
mechanism. This prevents a young child from
reaching through the gate and releasing
the latch. |
 | Other gates should be equipped with self-latching
devices. The self-latching devices should be installed as described for
pedestrian gates.
|
How to Prevent a Child from Getting
UNDER / THROUGH a Pool Barrier:
 | In many homes, doors open directly onto
the pool area or onto a patio which leads to the pool. In such cases, the
wall of the house is an important part of the pool barrier, and passage
through any doors in the house wall should be controlled by security
measures. The importance of controlling a young child’s movement from
house to pool is demonstrated by the statistics obtained during CPSC’s
study of pool incidents in California, Arizona and Florida. Almost half
(46 percent) of the children who became victims of pool accidents were
last seen in the house just before they were found in the pool.
|
 | All doors which give
access to a swimming pool should be
equipped with an audible alarm which sounds
when the door and/or screen are opened.
The alarm should sound for 30 seconds or more
within 7 seconds after the door is
opened and should be loud, at least 85
decibels, when measured 10 feet away
from the alarm mechanism. The alarm
sound should be distinct from other sounds in
the house, such as the telephone,
doorbell and smoke alarm. The alarm should
have an automatic reset feature.
Because adults will want to pass
through house doors in the pool barrier
without setting off the alarm, the alarm
should have a switch that allows
adults to temporarily deactivate the
alarm for up to 15 seconds. The deactivation
switch could be a touch pad (keypad) or
a manual switch, and should be located at
least 54 inches above the threshold
of the door covered by the alarm. This
height was selected based on the reaching
ability of young children. |
 | Power safety covers can be installed on
pools to serve as security barriers. Power safety covers should conform to
the specifications in ASTM F 1346-91. This standard specifies safety
performance requirements for pool covers to protect young children from
drowning. Self-closing doors with self-latching devices could also be used
to safeguard doors which give ready access to a swimming pool.
|
Indoor Pools:
 | When a pool is located completely within a house, the
walls that surround the pool should be
equipped to serve as pool safety barriers.
Measures recommended above where a
house wall serves as part of a safety
barrier also apply for all the walls
surrounding an indoor pool. |
Guidelines:
 | An outdoor swimming pool, including an
in-ground, aboveground, or on-ground pool,
hot tub, or spa, should be provided with a
barrier which complies with the
following: |
1 .
The top of the barrier should be at least 48 inches above grade measured
on the side of the barrier which faces away from the swimming pool. The
maximum vertical clearance between grade and the bottom of the barrier
should be 4 inches measured on the side of the barrier which faces away from
the swimming pool. Where the top of the pool structure is above grade, such
as an aboveground pool, the barrier may be at ground level, such as the pool
structure, or mounted on top of the pool structure. Where the barrier is
mounted on top of the pool structure, the maximum vertical clearance between
the top of the pool structure and the bottom of the barrier should be 4
inches.
2. Openings in the barrier should not
allow passage of a 4-inch diameter sphere.
3. Solid barriers, which do not have
openings, such as a masonry or stone wall, should not contain indentations
or protrusions except for normal construction tolerances and tooled masonry
joints.
4. Where the barrier is composed of
horizontal and vertical
members and the distance between the tops of
the horizontal members is less than 45 inches, the horizontal members
should be located on the swimming pool side of the fence. Spacing
between vertical members should not exceed 1-3/4 inches in width. Where
there are decorative cutouts, spacing within the cutouts should not
exceed 1-3/4 inches in width.
5. Where the barrier is composed of
horizontal and vertical members and the distance between the tops of the
horizontal members is 45 inches or more, spacing between vertical members
should not exceed 4 inches. Where there are decorative cutouts, spacing
within the cutouts should not exceed 1-3/4 inches in width.
6. Maximum mesh size for chain link
fences should not exceed 1-3/4 inch
square unless the fence is provided with slats
fastened at the top or the bottom which reduce
the openings to no more than 1-3/4 inches.
7. Where the barrier is composed of
diagonal members, such as a lattice fence, the maximum opening formed by
the diagonal members should be no more than 1-3/4 inches.
8. Access gates to the pool should
be equipped to accommodate a locking
device. Pedestrian access gates should open
outward, away from the pool, and should be
self-closing and have a self latching device.
Gates other than pedestrian access gates should
have a self-latching device. Where the release
mechanism of the self-latching device is located
less than 54 inches from the bottom of the
gate.
 | The release mechanism should be located on the pool
side of the gate at least 3 inches below the
top of the gate. |
 | The gate and barrier should have no opening greater
than 1/2 inch within 18 inches of the release mechanism. |
9. Where a wall of a dwelling serves
as part of the barrier, one of the following should apply:
 | All doors with direct access to the pool
through that wall should be equipped with
an alarm which produces an audible warning when
the door and its screen, if present, are opened.
The alarm should sound continuously for a
minimum of 30 seconds within 7 seconds after the
door is opened. The alarm should have a minimum
sound pressure rating of 85 dBA at 10
feet and the sound of the alarm should be
distinctive from other household sounds, such as
smoke alarms, telephones, and door bells. The
alarm should automatically reset under all
conditions. The alarm should be equipped with
manual means, such as touchpads or switches, to
temporarily deactivate the alarm for a single
opening of the door from either direction.
Such deactivation should last for no more
than 15 seconds. The deactivation touch pads or
switches should be located at least 54 inches
above the threshold of the door. |
 | The pool should be equipped with a power safety cover
which complies with ASTM F1346-91 listed below. |
 | Other means of protection, such as self-closing doors
with self-latching devices, are acceptable so long as the degree of
protection afforded is not less than the protection afforded by the above.
|
10. Where an aboveground pool structure
is used as a barrier or where the barrier is mounted on top of the pool
structure, and the means of access is a ladder or steps, then:
 | The ladder to the pool or steps
should be capable of being secured,
locked or removed to prevent access. |
 | The ladder or steps should be surrounded
by a barrier. When the ladder or steps
are secured, locked, or removed, any opening
created should not allow the passage of a
4-inch diameter sphere. |
These guidelines are intended to provide a means of
protection against potential drowning's and narrowing to children under
5 years of age by restricting access to residential swimming pools,
spas, and hot tubs.
 | A portable spa with a safety cover which
complies with ASTM F1346-91 listed below should be exempt from the
guidelines presented in this document. Swimming pools, hot tubs, and non
portable spas with safety covers should not be exempt from the
provisions of this document. |
