Body Entrapment:
When a portion of the body
is held against the drain cover trapping the
swimmer underwater. This hazard is present when
the drain cover is missing, broken, or the cover
flow rating is not high enough for the pump(s).
Evisceration/Disembowlment:
When a person
sits on an open pool (particularly a child wading
pool) or spa outlet and suctions applied directly to
the intestines, causing severe intestinal damage.
This hazard is present when the drain cover is
missing, loose, cracked, or not properly secured.
Mechanical Entrapment:
When jewelry, swimsuit,
hair decorations, finger, toe or knuckle is caught
in an opening of an outlet or drain cover. This
hazard is present when the drain cover is missing,
broken, loose, cracked, or not properly secured.
Note: All suction plumbing must be installed
in accordance with the latest national and local
codes, standards, and guidelines.
▲
WARNING:
To minimize the risk of injury due to
suction entrapment hazard:
• A properly installed and secured ANSI/ASME
A112.19.8 approved anti-entrapment suction
cover must be used for each drain.
• Each suction cover must be installed at least three
(3-ft) feet apart, as measured from the nearest
point to nearest point.
• Regularly inspect all covers for cracks, damage
and advanced weathering.
• If a cover becomes loose, cracked, damaged,
broken or is missing, replace with an appropriate
certified cover.
• Replace drain covers as necessary. Drain covers
deteriorate over time due to exposure to sunlight
and weather.
• Avoid getting hair, limbs or body in close proximity
to any suction cover, pool drain or outlet.
• Disable suction outlets or reconfigure into return
inlets.

WARNING:
A clearly labeled emergency shut-off
switch for the pump must be in an easily accessible,
obvious place. Make sure users know where it is
and how to use it in case of emergency.
The Virgina Graeme Baker (VGB) Pool and Spa
Safety Act
creates new requirements for owners
and operators of commercial swimming pools and
spas. Commercial pools or spas constructed on or
after December 19, 2008, shall utilize:
A. A multiple main drain system without isolation
capability with suction outlet covers that meet
ASME/ANSI A112.19.8a Suction Fittings for
Use in Swimming Pools, Wading Pools, Spas,
and Hot Tubs and either:
i. A safety vacuum release system SVRS)
meeting
ASME/ANSI
A112.19.17
Manufactured Safety Vaccum Release
(SVRS) for Residential and Commercial
Swimming Pools, Spa, Hot Tub, and Wading
Pool Suction Systems and/or ASTM F2387
Standard Specification for Manufactured
Safety Vacuum Release Systems (SVRS)
for Swimming pools, Spas and Hot Tubs or
ii. A properly designed and tested suction-
limiting vent system or
iii. An automatic pump shut-off system
Commercial pools and spas constructed prior to
December 19, 2008, with a single submerged
suction outlet shall use a suction outlet cover that
meets ASME/ANSI A112.19.8a and either:
A. A SVRS meeting ASME/ANSI A112.19.17 and/
or ASTM F2387, or
B. A properly designed and tested suction-limiting
vent system, or
C. An automatic pump shut-off system, or
D. Disabled submerged outlets, or
E. Suction outlets shall be reconfigured into return
inlets.
For installation of Electrical Controls at Equipment
Pad (ON/OFF Switches, Timers, and Automation
Load Center).
▲
CAUTION:
Install all electrical controls at equipment
pad, such as on/off switches, timers, and control
systems, etc. to allow the operation (start-up, shut-
down, or servicing) or any pump or filter so the
user does not place any portion of his/her body over
or near the pump strainer lid, filter lid or valve
closures. This installation should allow the user
enough space to stand clear of the filter and pump
during system start-up, shut-down or servicing of
the system filter.
▲
DANGER:
Hazardous pressure: Stand clear of
pump and filter during start-up. Circulation systems
operate under high pressure. When any part of the
circulating system (i.e.locking ring, pump, filter,
valves, etc.) is serviced, air can enter the system
and become pressurized. Pressurized air can
cause the pump housing cover filter lid and valves to
violently separate which can result in severe
personal injury or death. Filter tank lid and strainer
cover must be properly secured to prevent violent
separation. Stand clear of all circulation system
equipment when turning on or starting up pump.
Before servicing equipment, make note of the filter
pressure. Be sure that all controls are set to ensure
the system cannot inadvertently start during
service. Turn off all power to the pump.
