Still, says Rowley. there is a logical way to tackle
this problem. "If
at these accidents in terms of risk and exposure." he says,
"children in wading pools are at the greatest
risk and have the greatest exposure because they tend to sit on the
bottom of these pools. In other words, public wading pools are a good
place to start retrofitting."
The state of North Carolina agrees:
Fueled by public outcry over a suction-entrapment
accident there, the state in 1994 required that more than 150 public
wading pools be retrofitted with dual suction plumbing. Pointing to this
example as proof that a retrofit mandate is doable, Rowley notes that
other states are also reportedly considering similar
Another condition found in a vast majority
of suction entrapments is the absence of a grate
or anti-vortex cover-which could have served as a protective measure to
prevent the accidents.
In many cases, the grate or cover was missing
fact that went unnoticed by the pool operators, lifeguards and service
technicians. In other cases, the cover was loosened somehow, either by
bathers or by degradation by chemicals
and UV light. In yet other
incidents, the grate or cover came loose or broke apart when the
victim came in contact withit.
One of the primary conclusions of the 1974 Swimquip
study was that it is impossible to become entrapped on a drain
that is protected with a grate having 1/2-inch openings. "Most of
the time, you can push yourself off the drain," Rowley explains.
"You simply wiggle or turn to break the seal your body has created
with the drain. "But if there’s no drain cover or
grate. he adds, "you can't
The study found that a grated cover was as effective
in preventing entrapment accidents as were anti-vortex drains. For
has recommended mandatory inspections of grates
and drain covers, noting that if the service technician or pool operator
detects any damage at all, the pool or spa should be shut down until the
grate or cover is replaced or repaired.
A third protective measure is the presence of a
shut-off switch installed near the pool or spa. At the facility
where Nickens was entrapped, for example, there was no shut-off switch
near the spa. As a result, her would be rescuers searched
frantically, but in vain.
