BARRIER REQUIREMENTS
AG105.1
Application. The provisions of this chapter shall
control the design of barriers for residential swimming
pools, spas and hot tubs. These design controls are
intended to provide protection against potential drownings
and near-downings by restricting access to swimming pools,
spas and hot tubs.
AG105.2
Outdoor swimming pool. An outdoor swimming pool,
including an in-ground, above-ground or on-ground pool,
hot tub or spa shall be provided with a barrier which
shall comply with the following:
-
The top of
the barrier shall be at least 48 inches (1219 mm) 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 shall be 2
inches (51 mm) 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 shall be 4 inches
(102 mm).

-
Openings in
the barrier shall not allow passage of a 4-inch diameter
(102 mm) sphere.
-
Solid
barriers which do not have openings, such as a masonry or
stone wall, shall not contain indentations or protrusions
except for normal construction tolerances and tooled
masonry joints.
-
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 (1143 mm), the horizontal members
shall be located on the swimming pool side of the fence.
Spacing between vertical members shall not exceed 1.75
inches (44 mm) in width. Where there are decorative
cutouts within vertical members, spacing within the
cutouts shall not exceed 1.75 inches (44 mm) in width.
-
Where the
barrier is composed of horizontal and vertical members and
the distance between the tops of the horizontal members is
45 inches (1143 mm) or more, spacing between vertical
members shall not exceed 4 inches (102mm). Where there are
decorative cutouts within vertical members, spacing within
the cutouts shall not exceed 1.75 inches (44 mm) in width.
-
Maximum
mesh size for chain link fences shall be a 1.25 inch (32
mm) square unless the fence is provided with slats
fastened at the top or the bottom which reduce the
openings to not more than 1.75 inches (44 mm).
-
Where the
barrier is composed of diagonal members, such as a lattice
fence, the maximum opening formed by the diagonal members
shall not be more than 1.75 inches (44 mm).
-
Access
gates shall comply with the requirements of Section AG105.2, Items 1 through 7, and shall be equipped to
accommodate a locking device. Pedestrian access gates
shall open outward away from the pool and shall be
self-closing and have a self-latching device. Gates other
than pedestrian access gates shall have a self-latching
device. Gates other than pedestrian access gates shall
have a self-latching device. Where the release mechanism
of the self-latching device is located less than 54 inches
(1372 mm) from the bottom of the gate, the release
mechanism and opening shall comply with the following:
| 8.1 |
The release
mechanism shall be located on the pool side of the gate
at least 3 inches (76 mm) below the top of the gate, and |
| |
| 8.2 |
The gate and
barrier shall have no opening greater than 0.5 inch
(12.7 mm) within 18 inches (457 mm) of the release
mechanism. |

-
Where a
wall of a dwelling serves as part of the barrier one of
the following conditions shall be met:
| 9.1 |
The pool shall be
equipped with a powered safety cover in compliance with
ASTM F1346; or |
| |
9.2 |
All doors with
direct access to the pool through that wall shall be
equipped with an alarm which produces an audible
warning when the door and its screen, if present, are
opened. The alarm shall sound continuously for a
minimum of 30 seconds immediately after the door is
opened and be capable of being heard throughout the
house during normal household activities. The alarm
shall automatically reset under all conditions. The
alarm system shall be equipped with a manual means,
such as touchpad or switch, to temporarily deactivate
the alarm for a single opening. Such deactivation
shall last for not more than 15 seconds. The
deactivation switch(es) shall be located at least 54
inches (1372 mm) above the threshold of the door; or
|
| |
| 9.3 |
Other means of
protection, such as self-closing doors with
self-latching devices, which are approved by the
governing body, shall be acceptable so long as the
degree of protection afforded is not less than the
protection afforded by Item 9.1 or 9.2 described
above. |
-
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:
| 10.1 |
The ladder or steps
shall be capable of being secured, locked or removed to
prevent access, or |
| |
| 10.2 |
The ladder or
steps shall be surrounded by a barrier which meets the
requirements of Section AG105.2, Items 1 through 9.
When the ladder or steps are secured, locked or
removed, any opening created shall not allow the
passage of a 4-inch diameter (102 mm) sphere. |
AG105.3
Indoor swimming pool. All walls surrounding an indoor
swimming pool shall comply with Section AG105.2, Item 9.
