Virginia Graeme Baker Pool and Spa Safety Act
June 18, 2008 Staff Interpretation of Section 1404:
“Federal Swimming Pool and Spa Drain Cover Standard”*
On December 19, 2007, the President signed into law the Virginia Graeme Baker Pool
and Spa Safety Act, named after the daughter of Nancy Baker and the granddaughter of
former Secretary of State James Baker. Graeme Baker died in a tragic incident in June
2002 after the suction from a spa drain entrapped her under the water. This Act was first
introduced by Rep. Debbie Wasserman-Schultz (FL) and was supported by the Baker
family and Safe Kids Worldwide.
There is an annual average of 283 drowning deaths (2003-2005) and 2,700 emergency
room-treated submersion injuries (2005-2007) involving children younger than 5 in pools
and spas. In addition, from 1997-2007, there were 74 reported incidents associated with
suction entrapment, including 9 deaths and 63 injuries. The new law is aimed at reducing
these deaths and injuries by making pools safer, securing the environment around them,
and educating consumers and industry on pool safety.
The Act specifies that on or after December 19, 2008, swimming pool and spa drain
covers available for purchase in the United States must meet specific performance
requirements. Additionally, public swimming pools, wading pools, spas and hot tubs
must meet requirements for installation of compliant drain covers. New drain covers
which meet the current standard are now beginning to make their way into the
marketplace. Additionally, in certain instances, public pools and spas must have
additional devices or systems designed to prevent suction entrapment.
U.S. Consumer Product Safety Commission (CPSC) staff has prepared this guidance
document that spells out the technical requirements of Section 1404 of the Act, along
with CPSC staff’s answers to certain enforcement and legal issues. This document takes
into account comments provided to CPSC during an open comment period in March
2008. Comments were provided by a member of the U.S. House of Representatives, state
government officials, pool industry representatives, safety equipment manufacturers and
representatives, consumer safety organizations, and others.
CPSC staff urges all public pool and spa owners/operators, state and local health and
safety officials, and those in the pool and spa industry to carefully review this document
as they work toward complying with Section 1404 of the Act prior to December 19,
2008.

ENGINEERING/MECHANICAL REQUIREMENTS
Note: italicized language is taken directly from the Pool & Spa Safety Act.
Drain Covers: …each public pool and spa in the United States shall be equipped with
anti-entrapment devices or systems that comply with the ASME/ANSI A112.19.8
performance standard, or any successor standard…
Staff interpretation: All public pools and spas must have ASME/ANSI
A112.19.81 compliant Drain Covers on or after December 19, 2008. The basic
requirements of the ASME/ANSI standard are:
• Cover material must be tested for structural integrity
• Cover must be tested for body entrapment and hair entrapment/entanglement
• Cover must display a flow value in gallons per minute (gpm) that indicates the
maximum flow rate for which the cover has been approved
Main Drain: The term “main drain” means a submerged suction outlet typically located
at the bottom of a pool or spa to conduct water to a recirculating pump.
Single Main Drain: …each public pool and spa in the United States with a single main
drain other than an unblockable drain…
Staff interpretation: A main drain is a term usually referring to a plumbing fitting
installed on the suction side of the pump in pools, spas and hot tubs (a suction
outlet). Sometimes referred to as the drain, it is normally located in the deepest
part of the pool, spa or hot tub. It does not literally drain the pool, spa or hot tub
as a sink drain would, but rather connects to the pump to allow water to be drawn
from the pool, spa or hot tub for circulation and filtration.
Staff interpretation: The term “single main drain” means a submerged suction
outlet, with or without a skimmer, connected to a dedicated pool pump. A pool
may have more than one single main drain if it has multiple suction outlets that
are each connected to a dedicated pump. A group of suction outlets connected
together is considered a single main drain if the centers of the outlets are located
within three feet of one another.
Staff interpretation: Pools and spas with multiple main drains are not subject to
the requirements of Section 1404(c)(1)(A)(ii).
Staff interpretation: Multiple main drains consist of, at minimum, two fully
submerged suction outlets per pump, with drain cover centers at least 3 feet apart.
While no maximum separation is noted, the connections between the outlets and
the pump are important for proper operation and should be certified by a design
professional and inspected by a licensed inspector to ensure hydraulic balance
between outlets and the main suction line to the pump.
1 The current approved version of this standard is A112.19.8-2007. There is an Addendum moving forward
through the ASME/ANSI ballot process to correct errors in the test method for UV light exposure. The
prior version of this standard is 1987 (reaffirmed in 1996) and addresses only hair entrapment potential.
3
Staff interpretation: Field Fabricated suction outlets are subject to the
requirements of ASME/ANSI A112.19.8.
Unblockable Drain: (7) UNBLOCKABLE DRAIN - The term unblockable drain means
a drain of any size and shape that a human body cannot sufficiently block to create a
suction entrapment hazard.
Staff interpretation: An unblockable drain, to be consistent with the test
procedures found in ASME/ANSI A112.19.8, would have minimum dimensions
of 18” x 23”, which represent the shoulder to waist measurements of the 99th
percentile adult male.
Staff interpretation: unblockable drain may include:
• Drain configurations that prevent a seal from occurring (large aspect cover,
such as 18” x 23” or larger cover)
• Long channels that cannot be blocked by the body (conceptual Figure a.
below)
• Large outlet grate (diagonal measure of 29” or more) (conceptual Figure b.
below)
• Circulation designs that do not include fully submerged suction outlets
Figure a. Long Channel Figure b. Large Grate
Conceptual Unblockable Drain Configurations
Devices or Systems Designed to Prevent Entrapment: …each public pool and spa in
the United States with a single main drain other than an unblockable drain shall be
equipped, at a minimum, with 1 or more of the following devices or systems designed to
prevent entrapment...
Staff Interpretation: In addition to having a drain cover or other anti-entrapment
device that complies with ASME/ASNI A112.19.8, public pools and spas with
single main drains must have one of the following additional systems or devices.
(I) SAFETY VACUUM RELEASE SYSTEM (SVRS) - A safety vacuum release system
which ceases operation of the pump, reverses the circulation flow, or otherwise provides
a vacuum release at a suction outlet when a blockage is detected, that has been tested by
an independent third party and found to conform to ASME/ANSI standard A112.19.17 or
ASTM standard F2387.
4
STATUTORY DEFINITION OF A SVRS: The term “safety vacuum release system”
means a vacuum release system capable of providing vacuum release at a suction outlet
caused by a high vacuum occurrence due to a suction outlet flow blockage.
(II) SUCTION-LIMITING VENT SYSTEM - A suction-limiting vent system with a tamper-
resistant atmospheric opening.
Staff interpretation: A suction-limiting vent system is also called an atmospheric
vent. It is a pipe teed to the suction side of the circulation system on one end and
open to the atmosphere on the opposite end. The pipe is normally full of water
equal to the same height as the pool. When a blockage occurs at the main drain,
air is introduced into the suction line thus causing the pump to lose prime and
relieving the suction forces at the main drain (suction outlet).
Conceptual Suction-Limiting Vent System to Relieve Main Drain Suction
Currently there are no approved voluntary standards for suction-limiting vent
systems; however, an ASTM International voluntary standards task group was
formed in March 2004 and is currently developing minimum requirements for
field-fabricated vent pipes. The performance of the vent, the ability to prevent
obstructions from occurring within the vent, and a test procedure to assess
performance are being addressed. The correct design and construction of the
suction-limiting vent system are important to the overall function and should be
certified by a design professional and inspected by a licensed inspector.
(III) GRAVITY DRAINAGE SYSTEM - A gravity drainage system that utilizes a collector
tank.
Staff interpretation: A gravity drainage system utilizing a collector tank is a
swimming pool/spa with a separate water storage vessel from which the pool
circulation pump draws water. Water moves from the pool to the collector tank
due to atmospheric pressure, gravity and the displacement of water by bathers
which removes the need for direct suction at the pool. This type of system is also
referred to as a reservoir, surge tank, or surge pit.
5
Conceptual Gravity Drainage System – Direct Suction Removed from the Pool
Currently there are no voluntary standards for gravity drainage systems or
collector tank specifications.
(IV) AUTOMATIC PUMP SHUT-OFF SYSTEM - An automatic pump shut-off system.
Staff interpretation: An automatic pump shut-off system would be a device that
could sense a drain blockage and shut off the pump system. Some safety vacuum
release systems may meet this definition.
One pump motor manufacturer has developed a circuit board for its motors that
monitors current to the motor and shuts the pump off when a noticeable change in
current occurs, possibly caused by an entrapped bather.
The National Electrical Code (NEC) regulation number 680.40 has a requirement
for an emergency stop switch for the pump to be located within 5 feet of a public
spa in case of bather entrapment. However, this switch is manually operated and
would require the presence of another person to activate the switch and therefore
would not qualify as “an automatic pump shut-off system” under this Act.
Currently there are no voluntary standards for automatic pump shut-off systems,
though the current SVRS standards provide release and response time
performance criteria.
(V) DRAIN DISABLEMENT - A device or system that disables the drain.
Staff interpretation: Staff is not aware of a product that meets this description that
is currently on the market. In the past, companies have developed products that
sealed the suction outlet or shut off the pump when a cover is removed.
Additional consideration can be given to physically removing the submerged
suction outlet (drain) by filling the sump with concrete (effectively removing the
suction outlet from the bottom of the pool) as long as another source(s) of water
for the suction side of the pump is(are) available, such as skimmers, re-plumbing
the suction outlet into a return inlet (permanently reversing flow), or permanently
disabling the suction outlet plumbing at the pump (removing the suction outlet
connection to the pump) to remove the suction entrapment potential at the
submerged outlet (drain).
6
Currently there are no voluntary standards for disablement devices or instructions
for filling or re-plumbing the suction outlet.
(VI) OTHER SYSTEMS - Any other system determined by the Commission to be equally
effective as, or better than, the systems described in subclauses (I) through (V) of this
clause at preventing or eliminating the risk of injury or death associated with pool
drainage systems.
Staff interpretation: This will allow the development of future products.
Currently, the Commission has not determined that any other system is equally
effective as, or better than, the systems described in subclauses (I) through (V) of
this clause. Further, there are no voluntary standards for such other systems.
ENFORCEMENT AUTHORITY
The Virginia Graeme Baker Pool and Spa Safety Act states that the requirements of
Section 1404(b) shall be treated as a consumer product safety rule under the Consumer
Product Safety Act. Under Section 19 of the Consumer Product Safety Act, it is unlawful
for any person to manufacture for sale, offer for sale, distribute in commerce or import
into the United States any consumer product that is not in conformity with an applicable
consumer product safety rule. 15 U.S.C. § 2068(a). Accordingly, on or after December
19, 2008, it will be unlawful to manufacture for sale, offer for sale, distribute or import
into the United States a drain cover that does not meet the entrapment protection
standards of the ASME/ASNI A112.19.8 performance standard or any successor
standard. Any person who knowingly commits a prohibited act under Section 19 of the
Consumer Product Safety Act is subject to a civil penalty under Section 20 of the
Consumer Product Safety Act. 15 U.S.C. § 2069(a)(1). Under current law, the maximum
penalty for one or more related violations is $1.825 million. Congress is considering
legislation that would increase this penalty to $10 million or higher. A willful violation
of the drain cover standard could result in criminal penalties, including fines or
imprisonment, under Section 21 of the Consumer Product Safety Act. 15 U.S.C. §
2070(a).
Any production, distribution or sale of a drain cover that does not meet the applicable
standard also could trigger a requirement to report to the Commission under Section
15(a) of the Consumer Product Safety Act. Specifically, a manufacturer, distributor or
retailer who obtains information which reasonably supports the conclusion that a drain
cover fails to comply with an applicable consumer product safety rule must “immediately
inform the Commission of such failure to comply…” 15 U.S.C. § 2064(b)(1).
The Act also addresses enforcement of Section 1404(c)(1), which identifies certain
required equipment for public pools. Specifically, Section 1404(c)(3) of the Act states
that any violation of the required equipment provisions is to be considered a violation of
Section 19(a)(1) of the Consumer Product Safety Act. As explained above, any violation
of Section 19(a)(1) may result in the imposition of civil or criminal penalties under
Sections 20 or 21 of the Consumer Product Safety Act.

ENFORCEMENT DISCRETION
Public pools and spas that are not in operation on December 19, 2008 need not meet the
requirements of the Pool and Spa Safety Act until they return to operation.
Upon re-opening for use by the public after December 19, 2008, all public pools and spas
must be in compliance with the Pool and Spa Safety Act, as specified in the engineering
and enforcement sections above.
LEGAL RESPONSE TO PUBLIC COMMENTS
a) One commenter asked whether section 1404(c)(1)(A)(i) applies to all new pools
constructed one year after date of enactment, or to all public pools in the United
States, regardless of the date of construction.
Section 1404(c)(1)(A)(i) provides, “Beginning 1 year after the date of enactment
of this title, each public pool and spa in the United States shall be equipped with
anti-entrapment devices or systems that comply with ASME/ANSI A112.19.8
performance standard, or any successor standard.” Because the Act does not limit
the requirement to pools and spas constructed one year after the date of
enactment, we interpret this requirement to apply to all public pools and spas
meeting the definition of public pool and spa in section 1404(c)(2) of the Act,
regardless of the pool or spa’s date of construction.
b) One commenter stated that section 1404(c)(1)(A)(ii) does not exclude pools and
spas with multiple drains.
Section 1404(c)(1)(A)(ii) provides, “each public pool and spa in the United States
with a single main drain other than an unblockable drain shall be equipped, at a
minimum, with one or more of the following devices or systems designed to
prevent entrapment by pool or spa drains…” The requirement that a public pool
or spa be equipped with an anti-entrapment device or system applies to public
pools or spas with a single main drain other than an unblockable drain. Thus, a
plain reading of the statute indicates that pools and spas with multiple main drains
are excluded from this provision.
c) Another commenter strongly recommended that the CPSC interpret Section
1404(c)(1)(A)(ii) to require anti-entrapment devices or systems for all pools that
have multiple drains—where those drains operate under independent drain
systems.
If a pool or spa subject to the Act has more than one independent drain served by
a separate, dedicated pump, then each such drain is a “single main drain” and
must comply with the requirements of Section 1404 (c)(1)(A)(ii).

d) Several commenters noted their states have pool and spa safety requirements that
differ from those in the Virginia Graeme Baker Pool and Spa Safety Act (“Act”),
and asked what effect the Act has on state requirements.
The Act contains no provision on its preemptive effect and, therefore, does not by
its terms expressly preempt state law. However, section 1404(b) of the Act has
been deemed by Congress to be a “consumer product safety rule” under the
Consumer Product Safety Act. For this reason, we believe that the preemptive
provisions of Section 26 apply directly to the Section 1404(b) requirement that all
swimming pool or spa drain covers manufactured, distributed, or entered into
commerce in the United States conform to ASME/ANSI A112.19.8. Drain covers
or other anti-entrapment systems or devices marketed or sold in the U.S. on or
after December 19, 2008 need to meet the new federal standard.
Congress required that each public pool and spa in the United States be equipped
with anti-entrapment devices or systems that comply with the ASME/ANSI
A112.19.8 performance standard and that each public pool and spa with a
particular configuration be equipped “at a minimum” with one or more
enumerated devices or systems designed to prevent entrapment associated with
pool and spa drains. The fact that the Act lays out “minimum” requirements
suggests Congress contemplated a minimum floor of protection, above which
States could regulate. The impact of the Act on a particular state law or
regulation needs to be assessed on a state by state basis. For a more detailed legal
analysis of this issue with regard to a particular state, see CPSC’s May 6, 2008
letter to the Florida Department of Health.
e) One commenter requested clarification as to whether all or what portion of the
1404 provisions (1404(a), (b), or (c)) are to be enforced as consumer product
safety rules.
Section 1404(a) provides that the requirements in section 1404(b) are to be treated
as a consumer product safety rule issued by the Consumer Product Safety
Commission under the Consumer Product Safety Act. Thus, section 1404(b) will
be enforced as a consumer product safety rule. Section 1404(c) is not
characterized by the Act as a rule, but the statute sets forth specifically that “a
violation of section 1404(c)(1) is to be considered a violation of section 19(a)(1)
of the Consumer Product Safety Act and may also be enforced under section 17 of
the CPSA.”
