How to Prevent a Child from Getting UNDER or 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 the house to the pool is demonstrated by the statistics obtained during the CPSC’s study of pool incidents in California, Arizona and Florida. Almost half (46%) 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 seven seconds after the door is opened. It should also 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 re-set 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 de-activate the alarm for up to 15 seconds. The de-activation 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, above-ground, 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 above-ground 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 and 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. The 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 seven 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 doorbells. The alarm should automatically re-set under all conditions. The alarm should be equipped with manual means, such as touchpads or switches, to temporarily de-activate the alarm for a single opening of the door from either direction. Such de-activation should last for no more than 15 seconds. The de-activation 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.
- Other means of protection, such as self-closing doors with self-latching devices, are acceptable as long as the degree of protection afforded is not less than the protection afforded by the above.
10. Where an above-ground 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 drownings of children under 5 years of age by restricting access to residential swimming pools, spas and hot tubs.
Exemptions
A portable spa with a safety cover which complies with ASTM F1346-91 should be exempt from the guidelines presented here. Swimming pools, hot tubs, and non-portable spas with safety covers should not be exempt from these provisions.
