本文对从事冷库作业的88名工人做了入库前后指端血流图的测定分析。结果表明,工人指端血循环损害程度与作业环境温度有关。不同的温度(0℃以下,0℃以上,室温)与工人局部血流量减缓,血管弹性减弱,血循环状态异常呈显著相关。随着作业环境温度的下降,工人局部血循环机能减弱。为加强冷作业工人的劳动保护,提高工效,建议在低温作业分级标准的研制中把-12℃作为特殊的温度级别。
In this paper, 88 workers engaged in cold storage operations done before and after storage of finger blood flow measurement analysis. The results showed that the degree of damage to finger blood circulation was related to the operating ambient temperature. Different temperatures (below 0 ℃, 0 ℃ above, room temperature) and local workers slowed blood flow, decreased blood vessel elasticity, abnormal blood circulation was significantly correlated. As the working environment temperature drops, workers local blood circulation function weakened. In order to strengthen the labor protection of cold-working workers and improve work efficiency, it is suggested that -12 ℃ be used as a special temperature level in the development of the classification standard for low-temperature operation.
