我们对某橡胶厂轮胎制造车间接触炭黑尘作业工357人进行了健康检查。 该车间历年炭黑粉尘浓度测定样本87个,平均浓度15.41mg/m~3(0.95～29.88mg/m~3),最高粉尘浓度超标2.9倍。车间有防尘通风设施。 该车间接触炭黑尘工人共365名,实检357名,受检率97. 8％。男性347名,女性10名。年龄平均36岁(18～68岁)。接尘工龄14.3年(1～39年)。 工种计有配料(配合)工24人,窑炼工262人,叉车工9人,保全工39人,半成品6人,微机员4人,电梯工3人,其它工种10人。吸烟307人,不吸烟50人。 接触炭黑尘作业工人临床自觉症状不明显,但随着工龄增加,少数工人出现呼吸道症状,咳嗽68人,
We conducted a health check on 357 people working with carbon black dust workers in a rubber plant tire manufacturing workshop. The workshop over the years carbon black dust concentration determination of 87 samples, the average concentration of 15.41mg / m ~ 3 (0.95 ~ 29.88mg / m ~ 3), the highest dust concentration exceeded 2.9 times. Workshop dust-proof ventilation facilities. The workshop contacted a total of 365 workers in black carbon dust, the actual inspection 357, the test rate of 97.8%. 347 males and 10 females. The average age of 36 years (18 to 68 years old). Dust-cleaning workers 14.3 years (1 to 39 years). There are 24 kinds of work (ingredients), 262 kiln smelters, 9 forklift workers, 39 maintenance workers, 6 semi-finished products, 4 computer workers, 3 elevator workers and 10 other types of workers. 307 people smoke, 50 people do not smoke. Exposure to carbon black dust clinical workers clinical symptoms are not obvious, but with the increase of seniority, a small number of workers have respiratory symptoms, 68 people cough,
