目前邮局信件分拣工人每日分信数量较多,平均工时较长;信件分拣工人每日极力伸长手臂次数,手抬高过肘次数和手抬高过肩次数分别占手活动次数的66.0%、74.4%和34.7%,明显不符合工效学操作姿势原则,建议根据有关标准和法规,采取相应改进措施。
At present, postal letter sorting workers have a larger number of daily sub-letters and a longer average working hours. Letter-sorting workers try their best to extend the number of arms, raise the number of elbows over their shoulders and raise the number of shoulders by hand respectively, 66.0%, 74.4% and 34.7%, which obviously do not accord with the principle of ergonomics posture. It is suggested to take corresponding improvement measures according to relevant standards and regulations.
