【摘要】：目的分析某鉛酸蓄電池企業(yè)引進(jìn)國外極板生產(chǎn)線進(jìn)行生產(chǎn)工藝改造后鉛和噪聲危害狀況。方法以某引進(jìn)國外極板生產(chǎn)線(調(diào)查組)和某傳統(tǒng)極板生產(chǎn)線(對照組)的鉛酸蓄電池企業(yè)為調(diào)查對象,分別進(jìn)行工作場所職業(yè)病危害因素檢測、職業(yè)健康檢查和職業(yè)病防護措施分析。結(jié)果調(diào)查組工作場所鉛煙和鉛塵水平超標(biāo)率均低于對照組(13.6%vs 71.0%,19.2%vs 72.3%,P0.01),調(diào)查組作業(yè)工人尿鉛水平超標(biāo)率低于對照組(15.6%vs37.5%,P0.05)。調(diào)查組和對照組工作場所噪聲強度超標(biāo)率差異無統(tǒng)計學(xué)意義(38.9%vs 43.5%,P0.05)),調(diào)查組和對照組作業(yè)工人聽力損失率、雙耳高頻平均聽閾≥40 d BHL和較好耳語頻平均聽閾≥26 d BHL檢出率差異均無統(tǒng)計學(xué)意義(43.8%vs 37.5%,9.4%vs 12.5%,3.1%vs 5.4%,P0.05)。結(jié)論極板生產(chǎn)線改造有利于鉛職業(yè)病危害的防治控制,但對于噪聲職業(yè)病危害的防治控制并無明顯優(yōu)勢。
[Abstract]:Objective to analyze the harmful situation of lead and noise in a lead-acid battery enterprise after introducing foreign pole plate production line. Methods A lead-acid battery enterprise with imported foreign polar plate production line (investigation group) and a traditional pole plate production line (control group) was used to investigate the occupational hazard factors in the workplace. Occupational health examination and analysis of occupational disease prevention measures. Results the levels of lead smoke and lead dust in the workplace of the investigation group were lower than those in the control group (13.6%vs 71.0 and 19.2 vs 72.3, P0.01), and the urinary lead level of the workers in the investigation group was lower than that in the control group (15.6vs37.5cm, P0.05). There was no significant difference between the investigation group and the control group (38.9%vs 43.5%) (P0.05) the hearing loss rate of the workers in the), investigation group and the control group was higher than that in the control group. There was no significant difference in the detectable rate of BHL (43.8%vs 37.59.4vs 12.5 vs 5.4g) between BHL with high frequency 鈮，
