1.1本安全性能规范规定了在游泳池、水疗中心、热水浴缸或涉水池中使用吸力限制通风系统防止吸力滞留时的设计和安装安全要求。 1.2排气口的目的是释放因吸入口堵塞而导致的吸入口真空。排气口用于防止吸入口处的人体滞留，也可以缓解肢体滞留。其目的不是为了防止吸引出口造成的其他伤害，例如毛发夹闭、机械夹闭或眼球摘除。 1.3以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This safety performance specification provides requirements for safety in design and installation when using a suction-limiting vent system for suction entrapment prevention in swimming pools, spas, hot tubs, or wading pools. 1.2 The purpose of the vent is to relieve the vacuum at the suction outlet(s) caused by any blockage of the suction outlet(s). The vent is intended to prevent body entrapment at the suction outlet(s) and may also mitigate limb entrapment. It is not intended to prevent other injuries caused by the suction outlet(s) such as hair entrapment, mechanical entrapment, or evisceration. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
