某制药企业洁净厂房新风量及工人不适主诉调查

Investigation on fresh air volume and workers' complain in a clean workshop of pharmaceutical enterprise

    摘要
  • 摘要:
    目的  调查及检测某制药企业洁净厂房新风量以及工人的不适主诉, 探讨控制对策。
    方法  对该企业洁净厂房进行送新风设施调查, 采用TY-9900数字微风仪对各工作场所空气入口处进行新风量的测量和计算。对工作人员进行不适症状调查, 采用SPSS软件对新风量不足和不适率的相关性进行统计学分析。
    结果  该企业洁净厂房各个区域统一采用屋顶向下送风的方式, 采用孔板式圆形送风口, 经检测, 8个工作场所有4个(如包装办公室、会议室等等)新风量未达到国家标准的要求, 工作人员存在不同程度的憋气、头晕、乏力、疲劳等不适症状。新风量合格区域工作人员主诉不适率为6.45%, 而新风量不合格区域工作人员主诉不适率为30.30%, 两者差异有统计学意义(P < 0.01)。各工作场所人均新风量与工作人员主诉不适率呈负相关(r=-0.234, P < 0.01)。
    结论  由于新风量不足, 员工长期处于不良空气质量的工作场所, 会造成健康危害。应从合理适宜的新风量、良好的空气净化系统、合理的通风设施布置、日常维护等多方面进行综合控制。

     

    Abstract:
    Objective To effectively improve the maintenance of fresh air quality in a clean workshop in a pharmaceutical enterprise, the fresh air volume in this workshop was measured and the complain of the workers was surveyed.
    Methods  The ventilation facilities were examined in this clean workshop. The wind speed of each fresh air inlet was measured with digital air meter TY-9900 and then the fresh air volume was calculated. The uncomfortable symptom of worker was survey with questionnaire.
    Results  In this clean workshop, when the workers using the round hole-plate air supply outlet, the fresh air was supplied downward from the roof. The calculated fresh air volume of some areas, such as packaging room, office rooms, and conference room, was lower than the national standard. The workers had the uncomfortable symptoms, such as suffocation, dizziness, weakness, and fatigue. The authors found 6.45% of workers in the areas with qualified fresh air and 30.30% of workers in the areas with unqualified fresh air had uncomfortable symptom respectively. The Spearman rank correlation analysis showed that there was a negative correlation between the average fresh air volume in each working area and discomfort rate of workers(r=-0.234, P < 0.01).
    Conclusion  Lack of enough fresh air in some areas of clean workshops would cause workers'health problem. Several aspects need to be considered to improve the fresh air supply, such as appropriate ventilation volume, good air purification system, reasonable distribution of ventilating facility and daily maintenance.
