摘要
目的 分析有机溶剂接触人群佩戴半面罩呼吸器的适合性检验结果及其影响因素.方法 采取方便抽样方法,选择84名有机溶剂接触工人为研究对象,在其佩戴好半面罩呼吸器后采用呼吸防护用品定量适合性检验测试仪进行定量适合性测试,并测量研究对象的11项颜面指标.结果 研究对象适合性检验通过率为71.4％(60/84);进行弯腰动作时的通过率最低,为63.1％(53/84).适合性检验通过组人群头宽、额最小宽、面长、鼻长、鼻深、头围和头长尺寸均大于未通过组(P值均＜0.05).二分类logistic回归分析结果显示,性别和面宽均为适合性检验结果的影响因素(P值均＜0.05);其中,女性工人较男性工人通过适合性检验的概率更低,面宽越大者通过适合性检验的概率越低.结论 大幅度动作可能会导致有机溶剂接触工人佩戴半面罩呼吸器的密合性降低.企业为有机溶剂接触工人提供半面罩呼吸器时,需重点关注女性和面宽较大者的佩戴适合情况.
Abstract
Objective To analyze the results of fit testing and its influencing factors on half-mask respirator among workers exposed to organic solvents.Methods A total of 84 workers exposed to organic solvents were selected as the research subjects using a convenience sampling method.The qualitative fit test apparatus of respiratory protection was tested after the workers had put on the half-mask respirats,and 11 facial indicators of the subjects were measured.Results The overall pass rate of the respirator fit testing was 71.4％(60/84).The lowest pass rate was 63.1％(53/84),which occurred during bending movements of workers.The head width,minimum forehead width,face length,nose length,nose depth,head circumference and head length were higher in workers who passed respirator fit testing,compared with those in the failing group(all P＜0.05).The result of binary logistic regression analysis showed that gender and face width were influencing factors of the respirator fit testing(both P＜0.05).Female workers had a lower pass rate of the fit testing than male workers,and workers with larger face width had a lower pass rate in the fit testing.Conclusion.Drastic movement may lead to a decrease in the seal of half-mask respirator of workers exposed to organic solvents.When providing half-mask respirator to workers exposed to organic solvents,employers need to pay attention to the fit of respirators of female works and those with larger face width to ensure the effectiveness of respiratory protection for workers.
