    一起室内游泳馆氯气刺激反应事件的调查

    An Event of Stimulus-response for Acute Chlorine Gas Release in Indoor Swimming Pool

    • 摘要:
      目的  调查某室内游泳馆发生一起多人急性氯气刺激反应事件的原因,避免今后类似事件的发生。
      方法  采用流行病学调查方法对室内游泳馆的设备设施和刺激反应患者进行调查。依据《公共场所卫生检验方法第1部分:物理因素》(GB/T 18204.1-2013)、《公共场所卫生检验方法第2部分:化学污染物》(GB/T 18204.2-2014)对游泳馆内空气质量进行检测,依据《生活饮用水标准检验方法》(GB/T 5750-2006)、《游泳池水微生物检验方法细菌总数测定》(GB/T 18204.9-2000)、《游泳池水微生物检验 大肠菌群测定》(GB/T 18204.10-2000)对游泳池水进行检测。依据《游泳场所卫生标准》(GB 9667-1996)进行评价。
      结果  现场检测游泳池水余氯质量浓度为0.07 mg/L和0.08 mg/L,均低于《游泳场所卫生标准》(GB 9667-1996)。游泳馆内空气质量及游泳池水卫生质量均符合《游泳场所卫生标准》(GB 9667-1996)。
      结论  此次刺激反应事件原因为泳池临时工清洗脚垫、篦子时,误将盐酸和次氯酸钠混合配制消毒液,瞬时产生大量毒性和刺激性气体,他是本事件的唯一原因。

       

      Abstract:
      Objectives  To investigate the cause of many people with acute chlorine gas stimulus response occurred in the indoor swimming pool, and to avoid the occurrence of similar incident in the future.
      Methods  The authors investigated the indoor sngimming pool facilities and stimulus response patients by means of pidemiolog survey. The tests of swimming pool air quality were based on the Examination Methods for Public Places-Part 1: physical Parameters(GB/T 18204.1-2013), and the Examination Methods for Public Places-Part 2: Chemical pollutants (GB/T 18204.2-2014), the test of swimming pool water were based on Standards for drinking water Quality(GB/T 5750-2006), the Methods of Microbiological Examination for Water in Swimming Pool-Determination of Aerobic Bacterial Count(GB/T 18204.9-2000), and the Methods of Microbiological Examination for Water in Swimming Pool-Determination of Coliform Bacteria(GB/T 18204.10-2000). The evaluation was based on the Hygienic Standard for Swimming Place (GB 9667-1996).
      Results  The tests of swimming pool water residual chlorine concentration were 0.07 and 0.08 mg/L, which were lower than that of the Hygienic Standard for Swimming Place (GB 9667-1996). The tests of swimming pool air quality and swimming pool water health quality were comformed to the Hygienic Standard for Swimming Place (GB 9667-1996).
      Conclusions  The temporary member of the stuff made a faulty operation, who mixed commercial concentrated hydrochloric acid with water disinfection liquid(sodium hypochlorite solution) for mats and strainer cleaning; a violent and exothermic chemical reaction occurred immediately between a strong acid and a strong alkali, which produced enomous amount of todic and pungent chlorine gas. It was the unique cause of the event.
