铬矿渣粉是制造玻璃的原料,其化学成份为CaO25～35％,MgO27～31％,Fe_2O_310～20％,Al_2O_33～10％,Cr_2O_34～6％,SiO_26～10％,具有强硷性,100～180目的粉末。 1987年5月铁路某车站发生一起有铬矿渣粉引起的中毒事件,13名工人收卸一车(61吨共1220包)铬矿渣粉,由于运载和包装不严,卸车时粉末撒漏飞扬,浓度很大,又当时气温较高(35℃),工人虽均戴有普遍纱布口罩,可卸到约一半时,工人均减呼吸紧迫,喉、鼻受刺激难受,头晕、咳嗽、恶心,重者呕吐,腹痛,似重感冒症状。经医院检查:眼睑、喉头轻度充血外,手、脸皮肤无异变,心(一),肺透视(一),血、尿常规未见异
Chromium slag powder is a raw material for manufacturing glass, and has the chemical composition of 25-35% of CaO, 27-31% of MgO, 10-20% of Fe2O3, 33-10% of Al2O3, 26-6% of Cr2O3, 180 purpose powder. In 1987 May there was a poisoning caused by chrome slag powder at a railway station. Thirteen workers collected and unloaded a chrome slag powder (12 tons in total of 12 tons). Due to laden shipping and packaging, Concentration is very high, but then the temperature is high (35 ℃), although workers wear gauze masks are generally can be unloaded to about half, the workers reduce the respiratory pressure, throat, nasal irritation discomfort, dizziness, cough, nausea, weight Vomiting, abdominal pain, like a cold symptoms. The hospital examination: eyelids, throat, mild hyperemia, no change in the hands and face skin, heart (a), lung fluoroscopy (a), blood, urine routine no difference
