我局是一个新线铁路施工单位,广泛接触矽尘,尤以修建隧道,工作面狭窄,且工期较短,给防尘工作带来一定困难。为了探讨我局矽肺发病情况,指导今后采取切实可行的防尘措施,我们将几年来矽肺普查的有关资料整理分析如下: 临床资料一、矽肺发病情况: 我局历年来共发现矽肺患者79人,其中Ⅰ期42人,Ⅱ期26人,Ⅲ期11人(见表1)。检出率为受检人数17038人的0.46％。我局矽肺的检出率较之同系统的局明显为低(见表2)。
Our bureau is a new railway construction unit with extensive exposure to silica dust, especially for the construction of tunnels with narrow face and short construction period, which brings some difficulties to the dust prevention work. In order to explore the situation of silicosis in our bureau and to guide practical dust prevention measures in the future, we analyzed and summarized the relevant data of the silicosis survey in the past few years as follows: Clinical data I. Silicosis incidence: A total of 79 silicosis patients were found in our bureau over the years, Among them, 42 were stage Ⅰ, 26 were stage Ⅱ and 11 were stage Ⅲ (Table 1). The detection rate was 0.46% of the 17,038 people tested. The detection rate of silicosis in our bureau was significantly lower than that in the same system (see Table 2).
