目的调查深圳市龙华新区企业三氯乙烯使用的情况,通过三氯乙烯防治知识现场培训的干预措施,预防和控制三氯乙烯职业性药疹样皮炎的发生。方法采取现场职业卫生学调查,了解三氯乙烯的使用情况,对该辖区内使用三氯乙烯的93家用人单位进行分组试验,干预组(50家)进行现场培训,对照组(43家)除不进行现场培训,其他不变,其结果进行对比。结果干预组使用三氯乙烯的单位数明显减少,在弃用三氯乙烯、三氯乙烯识别和敏感人群识别、防护设施设置方面与对照组的差异有统计学意义(P<0.01)。干预组干预前后的差异有统计学意义(P<0.01)。结论现场培训对预防职业性三氯乙烯药疹样皮炎的发生有积极的意义。
Objective To investigate the use of trichlorethylene in enterprises in Longhua New District of Shenzhen City and to prevent and control the occurrence of occupational drug-induced dermatitis in trichlorethylene through trichlorethylene intervention training on the spot. Methods A field occupational hygiene survey was conducted to understand the use of trichlorethylene. Group of 93 employers using trichlorethylene in this area were divided into groups. The intervention group (50) was on-site training, while the control group (43) No on-site training, the other unchanged, the results were compared. Results The number of units using trichlorethylene in the intervention group decreased significantly. There was a significant difference (P <0.01) between the two groups in the use of trichlorethylene, the identification of trichlorethylene and the identification of sensitive individuals and the setting of protective facilities. Intervention group intervention before and after the difference was statistically significant (P <0.01). Conclusion On-site training has a positive effect on the prevention of occupational trichlorethylene-like dermatitis.
