为了探索小型制鞋业预防苯中毒的途径，我们在萧山市三家小型制鞋厂安装了局部抽出式双吸风保温防护罩设备。车间苯浓度由安装设备前的122．7～878.4mg／m3降到30.8～45.3mg／m3．达到和接近了国家卫生标准，二年来未发生苯中毒。本文对该设备的防护效果进行了评价，认为是比较适合当前小型制鞋厂防止本中毒的一套成熟技术，建议推广。 In order to explore the small footwear industry to prevent benzene poisoning approach, we Xiaoshan City, three small shoe factory installed a partial pull-out dual suction insulation cover equipment. Benzene concentration in the workshop was reduced from 122.7 ~ 878.4mg / m3 before installation to 30.8 ~ 45.3mg / m3. Reached and approached the national health standards, two years without benzene poisoning. This article evaluates the protective effect of the equipment and considers it to be a set of mature technologies that are more suitable for the current small-sized shoe factory to prevent the poisoning. It is suggested to be popularized.
