SUCTION ENTRAPMENT HAZARD
This pump produces high levels of suction and creates a strong
vacuum at the main drain at the bottom of your pool and spa. This
suction is so strong that it can trap adults or children under water if
they come in close proximity to a pool or spa drain or a loose or
broken drain cover or grate.
The Virginia 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:
1. 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 :
1.1 A safety vacuum release system (SVRS) meeting ASME/ANSI A112.19.17 Manufactured Safety
Vacuum Release systems (SVRS)
For Residential and Commercial Swimming Pool, 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
1.2 A properly designed and tested suction-limiting vent system or
1.3 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 :
1. A SVRS meeting ASME/ANSI A112.19.17 and/or ASTM F2387, or
2. A properly designed and tested suction-limiting vent system, or
3. An automatic pump shut-off system, or
4. Disabled submerged outlets, or
5. Suction outlets shall be reconfigured into return inlets.
There are five types of suction entrapment according to The Virginia Graeme Baker (VGB) Pool and Spa
Safety Act
1
.
Body Entrapment
a section of the torso becomes entrapped
2
.
Limb Entrapment
an arm or leg is caught by or pulled into an open drainpipe
3
.
Hair Entrapment
or entanglement hair is pulled into and/or wrapped around the grate of the drain
cover
4
.
Mechanical Entrapment
the bather's jewelr y or clothing gets caught in the drain or the grate
5
.
Evisceration
the victim's buttocks come into contact with the pool suction outlet and he or she is
disemboweled
TO REDUCE ENTRAPMENT HAZARD RISK
Two function suctions outlets per pump must be installed to prevent entrapment.
The minimum separate of suction on the same plate must be at least point to point
measurement 1 meter (3ft) apart. It is used to avoid “dual blockage” by bather.
If suction is found damage, broken, cracked, missing or not securely attached during
regular checking, shunt down the pool and replace it immediately.
A vacuum release or vent system is recommended to install for suction entrapment release.
