very serious hidden
danger within pools and spas is main drain suction entrapment. The
United States
Consumer Products Safety Commission (CPSC) put out an immediate
release alerting the pool and spa industries of this very serious
problem. From 1978-1996, the CPSC reported 49 incidents, which included
18 that involved children between the ages of 2-14. Five of the 18
incidents ended in deaths due to body entrapment. Another 13 deaths were
contributed to hair entanglement.
The same week the CPSC report came out, a 16-year girl at a party in
Wall Township, New Jersey, lost her life in front of her friends and
faculty in an indoor swimming facility. The girl was in the spa and
dipped her head underwater to wet her hair when someone turned on the
high jet pump. The girl was held underwater by the powerful suction from
the main drain of the spa, while a lifeguard, police officer and
classmates struggled to pull her free. Some students even tried to bail
water out of the spa to lower the water level, but there was not enough
time.
How could a five foot nine inch teenager drown in three feet of
water, surrounded by people trying to help? The incredible force of the
suction trapping the girl under- water baffled the rescuers. The suction
force was somewhere around 380 pounds.
While main drains are essential for water circulation, there are very
old drain covers that need to be replaced. The new pump technologies
today now perform at an efficiency rate of two or three times the
efficiency of pumps from ten years ago, which is a real concern.
1. Body entrapment happens when a drain sucks a person against the
drain cover, sealing off the drain cover, the vacuum pressure builds,
and the person cannot escape.
2. Limb entrapment is when a person gets one of their limbs stuck by
the suction force of a main drain cover that is either missing or
unsecured, or by a side suction outlet that is not properly covered.
3. Hair entrapment occurs when
a swimmer's hair is sucked through the main drain grate and tangles in
what is called a sump and the hair swirls and knots, trapping a swimmer
underwater.
4. Evisceration or disembowelment is when an organ is drawn from the
body. This occurs when a person (often a small child) sits on an
unsecured or missing drain cover, and the intense suction pulls the
rectum and intestines from the body.
Last year there were 10 reported cases of entrapment. Over the last
five or six years there have been some new technologies introduced, to
create a better, safer swimming environment. Along with new technologies,
there are layers of protection :hat are available.
Drain covers should be
inspected daily.
Four Layers Of Protection
1. Educate staff and swimmers on Pool and spa drain safety.
2. Make sure the pool and spa have certified drain covers that are
securely fastened. Pool chemicals can break down plastic
covers. sure to inspect all drain covers daily, and replace any
cracked, broken covers. If the pool or spa is missing a cover, close it
and replace the cover. Drain covers should be firmly attached with stainless steel screws per the manufacturer's
instructions.
3. Hydraulically balanced dual main drain systems reduce the suction
of one drain and carries relief to the other, freeing anyone that could
become otherwise stuck.
4. Install a safety vacuum relief device (5VRD). There are new and
exciting technologies that have been introduced to the aquatics
industry.
5. There should be a pool and spa pump emergency shut off button that
is visible and accessible within the pool and spa area.
With layers of protection, community associations should need not to
suffer the anguish of such tragedies or bear the financial
responsibilities. All pools and spas, no matter how old, can be updated
with new systems and technologies to make them as safe as possible, at
minimal cost.
Drowning deaths by main drain suction entrapment can be prevented.
This year a court ruling in Florida award- ed a judgment against a pool
company, and its customer, an apartment community, a decision of over
$7,000,000 in damages because a teenager was trapped by suction of the
main drain. The teenager lived, and is now in a coma. This kind of
accident does not need to hap- pen at your community.
