摘　　要：目的分析高吸水树脂(SAP)粉尘作业人员佩戴防尘口罩的防护效果及各测试动作对口罩防护效果的影响。方法于2017年3月,选取某大型化工企业SAP粉尘作业人员49名,使用呼吸器适合性检验仪分别检测其在接受呼吸器佩戴培训前后所佩戴某款防尘口罩的防护效果,并研究各测试动作对口罩防护效果的影响。结果呼吸器佩戴培训后,SAP粉尘作业人员防尘口罩的防护效果合格率为95.92%(47/49),明显高于培训前的合格率[63.31%(32/49)],差异具有统计学意义(χ^(2)=14.69,P<0.01)。在总防护效果合格的情况下,大声说话时的呼吸和弯腰时呼吸佩戴口罩的适合因子(FF)显著降低(Z=-2.59、-4.20,P<0.01);且各个动作的防护效果合格率存在差异(χ^(2)=42.70,P<0.01),其中深呼吸的合格率最高(100.00%),弯腰时呼吸的合格率最低(70.21%)。结论加强劳动者正确佩戴口罩的培训有助于提高其呼吸保护效率;在防尘口罩总的防护效果合格的情况下,劳动者应尽量避免不必要的动作,尤其是大声说话和频繁弯腰。Objective To analyze the protective effect of dust masks worn by super absorbent polymer(SAP)dust-exposed workers and the influence of each test exercise on the protective effect of mask.Methods In March 2017,forty nine SAP dust-exposed workers in a large chemical enterprise were selected as subjects.The respirator fitness tester was used to test the protective effect of dust mask before and after training,and the influence of each test exercise on the protective effect of dust mask was analyzed.Results After training,the qualified rate of dust mask protective effect of SAP dust-exposed workers was 95.92%(47/49),which was significantly higher than that before training[63.31%(32/49)],and the difference was statistically significant(χ^(2)=14.69,P<0.01).When the total protective effect was qualified,the fit factor(FF)decreased significantly when speaking aloud and bending down(Z=-2.59,-4.20,P<0.01).The qualified rates of protective effect of each exercise were significantly different(χ^(2)=42.70,P<0.01),among which the qualified rates of deep breath was the highest(100.00%),and the qualified rate of bending down was the lowest(70.21%).Conclusion Strengthening the training of workers to wear masks correctly is helpful to improve their respiratory protection efficiency.Under the condition that the total protective effect of dust masks is qualified,workers should try to avoid unnecessary actions,especially speaking aloud and bending down frequently.
