4、e the lack of extensive epidemiologicaldata,the manufacturers,consumers,and users supported by CPSC staff decided on February 6,2001to proceed with dedicated time,expense,and effort toward development of a voluntary safety standardto reduce the possibilities of injuries due to swimming pool,spa,and
5、hot tub body and limbentrapment.If a cover or grate is unfastened,missing or broken,exposure to the drain suction force couldproduce evisceration.Even though it is expected that safety vacuum release devices may help inreducing cases of evisceration,the devices are not designed for nor intended to d

7、is not intended to and does not address hair entrapment.Field fabricated vent pipes are excluded from this specification and will be addressed in a separatestandard under development.1.Scope1.1 This specification covers requirements for safetyvacuum release systems(SVRS)for use on swimming pools,spa
8、s,hot tubs,and wading pools.1.2 This specification is intended to reduce the risk ofdrowning or entrapment by providing a rapid detection andrapid release of vacuum or preventing a dangerous vacuumaltogether when a person becomes entrapped at the suctionoutlet serving a pumping system.1.3 The values
